TRANSCRIPTIon

Zack: Hello everybody, my name is Zack Parnell.  I’m the Vice President of Operations at ITI, Industrial Training International. The webinar today is really interesting. I’m going to kind of touch on all what we’ve been doing with these Showcases, and before I turn over to Mike here, but this is much more than interactive demo, and I hope all of you see the message right here, see download the workbook. You’re going to need that workbook, to participate in our showcase today. But you really handy if you can print it out, and have some pencils nearby. Okay, well, let’s get started, so. For all of you that are joining us, I’m just happy to say:” Hello, and good morning, its 11 AM, here on the west coast of the US.” We have some folks more on our wall today, joining us and some might be light out, some might be dark out, so welcome. ITI again, is a world leader in crane and rigging training. We’re specialized in those two items specifically, we don’t sell any product, and we don’t sell rigging or anything like that. We are an education company, and we’re happy to do this once a month. This is basically the showcase webinars series, and what we’re trying to do is, bring some insights to customers and prospects that are interested in learning about the industry, and about ITI.  But as you can see, some of the industries that we serve, as you all know, crane and rigging activity span across the dozens of industries. So, we are doing the trade training, if you will for dozens of industries and our key providers for lot of major customers, around the world. Just to touch on that, want to get some shout-outs to some folks that are here, from a customers including, Alston Power, and Argon national labs, BHP Billitin and BP. We also have some folks that are new, and, let’s see. BAE Systems, Steve from Norfolk I think. And, Mike was giving me a document before he’s interested because, there are actually 25 countries represented here, that which is the most that we have had. There are folks from Saudi Arabia, South Africa, India, Britain, Nigeria, Philippines, Australia, etc. So, in addition to that, North America, there is 25, no, 40 states, I’m sorry, represented in US, and 6 provinces in Canada. Like I was talking about the showcase, you guys can all go down to, ITI.com / Showcase, and download, well actually just watch from a web page, the past presentations, okay? Those includes Cranes, Rigging & Your Organization, Effective Crane & Rigging Training Methods for Your Employees, Heavy Intermodal Lift & Transport, this is a really what all we just did a last month, with Barnhart’s Jim Yates, SVP of Engineering. Today of course, we’re doing a master rigger overview, like I mention, again, go to the web page, if you need, download the workbook, and then upcoming, we have Lift Planning Considerations, in August, and then, ASME B30 & P30 Developments. And the major reason we’re doing the ASME Developments Webinar is because Mike Parnell, the vice-president of the ASME B30 Committee. Lot of customers call us to know, lot of times to understand legislation and the standards, and also the P30 is the Committee that oversees Lift Planning. And that standard, I believe Mike will touch on, but it’s coming, I don’t think its published yet, it’s coming out soon.  He has been working out this way all year at it, but, as you all know, ASME standards are accepted very much so in the Western hemisphere, US and Canada especially, and Mike is an industry leader in our industry obviously, and his focus points are wire rope and rigging, he’s also serves as a third party witness testimony in a lot of aware rigging accidents. He’ll probably touch on some of those we go through the workshops today, as they, lot of them apply to rigging selection load control, and alike. I’m not sure over here that Mike, where we get started, but the idea the purpose of the course, at this webinar, is to go over the course, and why we conduct the Master Rigger course as we do. And we’re going to give you all, pretty much half of 60 percent of the workshops, I’m sure that webinar will be on the workshops, including Load Control, Rigging Selection, Center of Gravity. Then sure we’re going to again hear the Mike, thank you all for joining, and we’ll get started.

 

Mike: Okay, I’d like to welcome everybody, and thanks for the intro Zack, and we’re very excited to have you join us today. And please make sure that you’ve downloaded the Master Rigger workbook, that 7 page document that’s just select for today’s presentation. In the process of those workshops will be considering items that have to do with Load Control, and proper rigging techniques, and then, Rigging Selection, based on load distribution, and then also Center of Gravity of course. Make sure you get that downloaded, as we go along, if you have questions, you’d like to type those in, and sent those in, I will deal and work with all the questions possible, towards the end of the presentation, some of   those maybe collected together, maybe 2 or 3 questions are very similar, those will be compiled, and I do my very best to respond to those. Make sure that you get the question put in what you like, and also be thinking about the impact of the presentation as far as your organization, how these workshops or for this type of information can best serve your needs, make your own applications, and your Crane and Rigging Environment.  Also we have, this is the little bit of an overview of who really is, sort of the Master Rigger Canada, and in particular, our folks that have some of course experience in crane rigging activities, it won’t have to be really the superman, in your organization, but there are a lot of folks that as we talked over previous webinars, we really want to make sure that we’re attending to those 1 and 2 year folks, there are going to be growing into the 3 and 4 year blocks, and there will be folks that we want to help really take forward and for skills training, and skills enhancement, so it’s, those are great candidates, you can see a whole listening here ,jobs titles, the folks that may fall into the titles that you have, within your organization are very  similar. And nearly every type of industry, have a need for folks that have the skills and traits, and abilities, knowledge for advance rigging. A lot of things we’re seeing today, qualified riggers oversee basic riggers as well. This is qualified rigger, and advance rigger master rigger lift director, when you look directly, all those kind of folks in those industries, really benefit from course information that is contained in a program like this. The rigging subjects that we particularly attempt to, in this program, and this is offered in Woodland, Washington, and Memphis, Tennessee and also on site. I’m actually; we’re doing a special course for Agrium up in Edmonton Alberta, a very similar to this. We’re doing this on site and take some preparations, and some equipment. But, subject in course content will be dealing within almost every Master Rigger course, are the core  element of good rigging, and taking them up to implementing, engineering  and principals for laymen . And that’s the idea that, not teach over anybody head, it’s brining all down to so we can all understand, and graphs, and settle that, and put those rocks in our backpack, so, that we prepared, for any job that comes across to us that we can handle effectively, and within control and using proven principals, good practices, and keeping our people safe. These are the items that we’re really focus on, and particularly distribution of load, of course the 3 basic elements the core basic elements of rigging what’s the load weight? Where is the center of gravity? And how we’re going to control it? And so, those are the sprinkled into our course, and any Master Rigger course, there is also a Core Foundation upon which we build a good rigging job, and a rigging plan. Where these are the offer the course, at, they can be for your facilities, and at any of our train centers, in the US, and Canada, and then we do have an e-learning module series that I believe are 12 different modules of, e-learning modules that are deal with advance and Master Rigger subject. It’s available to you in variety of packages, variety of mediums, so, take a look and entertain how that might best serve your organization. There are, we work hard to, provide in the neighborhood of, least 50 percent classroom information, and 50 percent hands on information. It’s very important. We’d like to get dirty, and sweat a lot of course all we’re doing a program, because that’s when real learning takes place, is speaking while doing and defending those decisions, all help us imbedding those skills, and those pieces of knowledge in a for a long term. A tone of hands on, it’s really important. Got that equipment, need the play area, need the loads. We use a lot of dynamometers that help prove, and confirm calculations, in advance, it’s a great it’s probably our most fun program, but it’s also most enriching skills and enhancement program that we offer. Take it into this program, we work with chain falls,  load, trans for using chain falls, you can see just a couple, I’m just going to burns through a number of pictures here, but, we’re going to in a half certain load and imposed on these overhead  connections point we integrate dynamometers, along with the chain falls to confirm those values, but  if this load has to come from this location, make a pass, looks through window, and get place down or transfer .We know in the old, rigging approach we have  length divided but high time share of load weight. And so, both, in the web drifting operations, we always had to decongest, on what implodes were imposing on those overhead varied points, or connection points, could be beam clamps, that are used appropriate within a given angle, or hurt connection points. We really want to make sure we don’t overload anything, especially where it comes along, a chain falls that we might be using for that.  These dynamometers go along ways to help confirm and validate their apply, the anticipate intentions, where we standing, we always use those overtraining program, and, the proper methods. You’ll see Michael Johnson here one of our instructors, that we’re out of the line of fire, we stand up to the side, where were chain falling, and case we have any brake issues, slippage or anything else. This loads making that pass, we want to make sure that, from an operational standpoint, we’ve got our people, really taking  care of they are off to the side, out of the line of fire, and so, that there, away from the pendulum action should any incident occurred. It’s all about the safety for person, safety for the equipment, and the facility, the building, the location we’re using. Another subject just quickly, is load distribution, and we know we’ve got given pay load, and in this case we’ve got the car body down here,  this weights about 4800 pounds, and this been rigged up in a full point pick, where using picks connection point shackles and hitches. We rigging up to a spreader bar, lifting beam, actually. And you notice that the load is very high, to a one crane, and a very load to another crane, particularly with a pick point. So how do we distribute out that weight of that, payload load the weight of the rigging, and also the weight of the beam out of these two cranes that are providing the lift, and it doesn’t… it seems really complex, but really in a Master Rigger within, 45 minute workshop, people are ramped out very quickly, and how to, arrived at those values, and those decisions. Here’s another of knuckle off of 966 loader, and this guy right here is a being rigged up, we’ve got a power pick point of up here, that origin to, far out on one side closer another, and that’s going to definitely impose more load to one side to the other. And we want to make sure that, in any given time that is a Beam Trolley transfer, using a lifting beam for reallocated the load of various cranes, and so on. We’re a capable of identifying how much load to each of those cranes, that’s really important to the operators, of course, that’s also important to us, for knowing what we’ve got, for a rigging tension, and how we’re able to manipulate or control that loads through the path.

 

So, let’s go on to the incline plane, things get rolled and ramped up. We’ve got couple of ramps that we use for training activities, of course is going to have a certain height, certain ramp length, height level and certain length on the incline. That’s going to produce greater load for our winch, using, or pulling system up here, and once we get up to the flat, then we just got double the weight, times the coefficient of friction, is that going to give us required force to pull that load, but when we come up and incline, we certainly have some different, additional tensions to deal with. Up or down, and we’ve got the anticipate, that make sure that our origin is right, and that our winch is capable, and then our load control of course, within this case we’ve got single steering unit down here, and 2 tops, one on each hand, to make a nice triangular move, and sort of the three point, looks to rolling system, we almost always preferred rolling the 3 versus 4, rollers to help intent continue the maintain load, to our pick points, our bearing points, based on the center gravities location. We’ll decide how much load to that front steering or the verse steering roller, versus the 2 on the other end, so, we’re constantly making sure: What’s the weight, what’s the CG how’s that effect in my capacity for the rigging or attachment you are supporting it with? Pretty intense process, here’s another incline the different rolling system, we’ve got a barrow right down here that connected to those 2 prop top rollers, and we guys steering mechanism, steering roller on the back. In this case, this was like assize, think that is our smaller unit, that’s a pipe size unit, so we have one and a quarter time, for capacity for each of 2 front top rollers, and then 2 and a half time capacity for the back roller, this back over here. We’ve got another 25 times that rolling step, that is capable of moving braded, sizes of a load. So, each time we’ve got to make sure that we’ve got the each roller is capable, supportive, and participate the load dedicate and based on permission to CG, and overall weight. So, those are always elements that we’re considering, and that concerned with.

 

Here’s the 25 times rollers test them on just that similar unit. Notice, this is a little unique, here we got always make sure for jacking and rolling, I want to bring this year intention, and notice we’ve got some steer place, we’ve got cut handles into. We’ve got to make a transition, and it’s really important. This is an upper slide concrete pad, and slightly lower pad, we’ve got about inch and a half, transition to make, right if it’s a break line right here. So, we’ve insole some steer plates for a small ramp weight to, be able to step that load up, and to make the transition up, so we don’t disrupt, or interrupt, or not get any rollers outcome under these. Transitioning from floor space, or from sometimes jumping over expansion joint, or all the other elements, a good master riggers going to take look of this, and entire on their way make sure that we make those transitions appropriately, and not at below hung up, not have to jack and brings that rollers to new position, because we didn’t prepare for this transitional element. Those are all parts of, good master rigger program we’re putting challenges in front of people, making sure they can deal with it, and then teach through, work through all the possible solutions. We use mechanical jacks, and we use the hydraulic jacks, and we also use airlifting bags, as our lifting systems, for all of the programs that we conduct in this case, we’ve got a hydraulic jack always ensure we’ve got a good foundation, and good support for it. In transferring we constantly use blocking, of course, and instructing and proper methods for block, and search and removal never getting your hands underneath the blocking, always hands on top on them, so that in case that we have any jack issues that knocks that blocking out of our hands, or hand isn’t trapped underneath, so, techniques, methodology all those things come into the play, when we’re providing that instruction. This is an air casters system, we’ve got a number of these, and all of our facility, and the air casters are placed, you can see right underneath here, and right up underneath, and these have tonnage capacity, this is 7 tone unit, and so back, this, there will be 4 these in this case, because, we have the ability to a reconcile system, to be able to manipulate the air pressure, and air volume, to the different air casters, they have the non-skip grip type, top on them, and were able [Inaudible]. And then manipulate the load through, the nice clean surface area, we can, industrial folks had a take care of working over rough surfaces. Sometimes there are cracks in the floor we can fill those, and tape over them or run aluminum over the top. There is a brighter method how to do that, with some uneven surface, but these are great systems for moving and cleaning rooms, and areas that you’re, I don’t want to do any markings on the floor, or floor indentations that might be coming from the Hellman roller or some other rolling system. So, let’s say we work at using brighter tools, and not that [Inaudible] 20:34-20:37. Of course, angles, and tensions based on center of gravity, of load, there are this case, we have a lifting beam that it has a brighter pick points and pad as across, that give us an opportunity to put different pick points, and different rigging points, across this entire top surface, this load. We made it up with a very short leg on a one side, and very long leg on the other. Of course dynamometers will be put in the place. But it really makes leave us out of people, and we take heights divided by … lengths divided by heights and share of load, and all the sudden the light bulbs go on, and everybody starts to grabs very quickly, tension doesn’t agrees with the angle decreases, so, great tools, and great equipment to be able to use this canopy develop, that should location as necessary. Lifting angels of course are ball down for standard load rigging, with mobile crane, and these become really great instructional tools, and great reminders of tension is increase thing as the angle is getting flatter to the risen.

 

Load control is a huge issue, we do lot acts and investigation, and expert witnesses were. And good rigging methods, pull rigging methods can be impose in varies places, varies locations around, facilities. And, you notice we’ve got the, full knock alarm here, for a small loader. Notice we using a tone of sling protection, and in some cases it will be cut protection, and some cases it will be abrasion protection. We have mass card cover, cover mass, we use a lot of rigging products, as corner around, all kind of things, but have a collect that rigging up at the very top, and making sure that, there is nothing that can’t happened, that can, have that load go kind of [Inaudible] and then end up with the load slip on it, or slip or sliding. We just have to make sure that every time we grab that load, we‘re going to dictate required worry, going to apply to how it’s going to, in what orientation, what edition. We never want to be surprised by loads up ending, and slipping, because we’re poorly rig, so, load control is the big issues for us, and also, certainly slip protection is a huge element. These are all; taking in a consideration of, it got to be big shifters, and some knuckles, and [Inaudible] items, you see the center of gravities right there. And rigging to that CG is really important, get that thing, a level in case we have to insole it in certain location. Lot of time we spent with varies teams there, with sign different rigging projects around the yards, inside the building, to make sure load control is very top priority, for them, while they dressing a project. And load training course is a big issue, lot of slings get cut because of load training takes place in all some things that to happened, end up with load that looks like this, and we’ve got, unfortunately we’ve got situations at times, we’ve got pick points, and we might have [Inaudible] to set, that, is on the outside, and, we… unfortunately we made up with slings, for time to time, that get rigged down ,to those corners. We’re going to up right this load in that direction. Really what needs to be happening because you, we know what’s going to, as this load breaks over, when it turns this load up, when they have a step block, right over here, that’s going to accept that load, so that we don’t slam the crane over, and stop block over, rest that load from that complete over turn, and the table set, accept that load to could step up, and then lift. So, what happens though, with this plan, makes this rotation around that corner, and continues to fight as at makes that pass, eventually the sling will be in this orientation. And this is a huge cutting issue in order load scrubbing and damages. So, we really work hard to let’s drop in a spreader bar right here, and make the pass, and allowed us to really rotate completely incline without any making contact with that load, is really going to be the answer. And so, you get into the some instruction, and use some equipment to help prevent damage to slings, damage that drop load, and people getting hurt. Slipping in a [Inaudible], I mean, you can get a 5 ton spreader bar like this for 800 bucks, and that’s a pretty cheap investment maybe 6 foot, 8 foot, 10 foot, but it ends up with pretty cheap investments and be able to complement load turning activities, and varies facilities, so just simple answers that all sudden avoid this sling damage, and cutting, and all kinds of potentials downstream. I would strongly suggest, we take look at rigging tool room, or gear box, or gear boxes, where we’ve got rigging store and make sure got appropriate equipment to performance the assign tab. Just ideas kind of imploding up there, load training of course. These is a 2 cranes pick, they are pick concern, mostly does pick points whit the extensions down here, we’ve got pick points, and we’re sharing a load, which rolling blocks right here, and we’re able to pick and rotate that load up, we know we’ve got x pounds of loads for that crane, x pounds of load here, and it’s riggers, we need to make sure that we’re protecting the rigging, during this pick and turn process. This load probably a 33 thousand pound load and we want to make sure nothing is overload in the process, and we’re able to make that turn clean. This is just not very long , we had to get this tower section up righted , so, that multiple crane list is really big deal and typically we were encouraged OSHA calls out for multiple crane lists, as something upload into what they would defines as critical lift, they actually don’t reach all that out, and many of the documents, but that would be a making sure that we’ve got a list plan basically from most cranes, how much load would  be on each crane, based on  where we’re rigging and suspended for, so, multiple crane picks is the big deal, the issue is, we swing away with one crane too far in one direction. And we’ve get out of qualm with that hoist sling; we’re certainly going to get out of plum with the other hoist sling. And, potentially pull this crane up along with this crane over, so; one crane is can be doing lot of damage to its brother while making a list like that. It’s all about the orchestration, signaling, the planning; good routs, and stand up with the crane, maybe side by side versus dueling booms, or facing the cranes to each other’s. It takes a lot of planning, and make sure, in this part of the Master Rigger program, incorporates this type of list activities.

 

Let’s go right to have a, kind of one of the last subject, winching, of course, we need to have engineer to number of ankle plates, to help a secure our winches to, end up facilities, and to make sure we can have suitable pulling points, and of course, pulling, using multi-part lines, up, to incorporate the brighter method to get loads relocate from point A to point B. We could go very quickly now into our workshops, and we’re going to ask you to give the workshop handout that was provided to you, it’s the 7 page document.

 

Let’s go through that, I’m going to flip to that screen right now. And let’s take a look at. This is should be what the cover looks like for you, and it’s got a nice, it’s a little 2 crane pick on a cover right there. This is a little intro inside of that, on a page 2, and it shows that table of contents, what we should have, in our little handout here, is that Journeyman Riggers Reference Card, The Master Riggers Card, Load Control, we have 3 workshops on pages 5, 6 and 7. So, let’s take a look then at the journeyman card, above on top on the screen we’ve got an additional this is one of the probably 6 or 7 different projects that are available, we produce, we produce the flat point view on a side by side, per your page today to work through, for workshops. And, certainly there are varieties; I do want to bring up a couple of others to you that you don’t have. We do have origin with the big step card and just put it upon the screen, and this particular has, card has the reference wire rope sling that is really with items, with 10 tons to 15 hundred tons. So, it’s the big brother to this journeyman card, and you’ll notice if you will, down here on panel side for this origin with the  make step card it’s not  been provided to, we made agreement with Crosby, and we put the wide body shackles, ongoing up to 1500 tons. And we incorporate this card, of course this standard shackle sizes up to 6 inches over here, and we incorporate that in with workshops example on the back of the cards that, this case, this load is 380 ton, and we ask the, you know, take through the content, of the cards identified of variety of items that, which shackles should be used at these points, based on the anticipated load, which slings, round slings, which size shackles, 125 ton spreader bar, big braided wide rope slings, large spreader bar, and then of course, our top slings. Those are all, available by site and selection based on that part. Notice on this 9 part braided slings, I know we‘ve got number of attendees on a call today that bring us world, they’ve got 3  inches, 3 and a half component rope that makes up to 14 inch finish rope sling diameter that over stand 100 contra vertical, so there are wider cards that provided this information to on those to that you have in  your a workbook, I want you to bring us the attention , and let’s take a look, with you have of course a rigging inspection of card. Multiple colors to help represent what [Inaudible] and that are meant, for inspection requirement, and so that card is available to it. And probably, sold in a last 24 years that somewhere in the neighborhood the 3 million cards, in 7 different languages, so, check in the book store and might find these to be helpful downstream.

 

The card that you have in front of you will be used in a variety of sections, and I’ll be working with you, on which panel we really going to need, for which particular workshops. A particular answer right now, I’m going to ask you to take a look with me, right over here on this panel for the journeyman card , which is on page 3, in your handout, and we’re going to take a look on these hitch types right here, for just to  minute. There are 7 different hitch types, 1, 2, 7, 8, and 9 we’re up to 14 so we have 14 different hitch types. And they’re all described right down here underneath in that bottom panel.  We have single vertical, 2 leg bridle, 4 slings, 3 leg pick, 3 slingers, I remember 5, or hit somewhere 5 and single basket, and number 6 of course is a double wrap basket and so on. So, let’s kind of keep those in mind, and let’s go over the page 4, let’s go start from page 5, and here’s the kind of the get primer for workshops today, we have 5 different load types, that are presented to us, and up those load types, let’s take a look at, good rigging methods, that will accommodate reasonably good and safe lift.  Not about capacity, it’s just about load control, so, the instruction here, I’d like here to do and work with me is, on sample one, or load 1, which one is a preferred rigging method that will provides the better positive load control. Circle A or B, A or B in each case, and 1 through 5, and identify the better technique for each one, and circle that, and I want you to do that, and I only give you about 15 seconds here, to get those marked on your page, and then we’ll review them, for everyone, and before go on our next workshop. Go ahead, and mark those up, I’ll bring this up for size here.

 

All right excellent, so, we have, let’s take a look at item 1, this load is common L load, in a center of gravity, of course is not very happy. It’s little over, lost on one side there, and that’s kind of be the central point here, the center point there, and based on density of materials, and so on the CG is about there. And, the key question you’re want to ask yourself, any time you’re reviewing  load being rigged, is sort of the, we put the scent to the north, south, east, west perspective, and how I ,want to rely that to you? Let’s take a look at one A, how many of you were picked one A, or one B? And I would hope lot of you picked B as our positive, as correct solution. Want to take a look at, one B, and it provides good control, and this, we call this as east west direction, that load really can’t go anywhere, in east west orientation or in north and south orientation. So, let’s take that same question, and look at one A. And then east west direction I’d say, that’s a big no. This inverted basket right here, you know, if you take a look back in the rigging card, on the journeyman card; let’s take a look over here. Let me take you down to panel 5 down here, we’re on page 3 panel 5. Just something to bring it in mind, coefficients of friction right down here; a look for the coefficients of friction for steel on steel, right up here we’re looking at 10 percent. And 10 percent coefficient of friction is very low friction. So, we only go back to our little drawing  here, and with 10 percent friction we have steel crane hook, with a steel sling, we just have 10 percent coefficient of friction that help stick that sling to the hook, and that’s not very much help. Especially if the center of gravity is off set, and it’s not in a very good place. We’re actually working on a court case right now, with the jib coming of the side of the hydraulic crane, and a jib looks something like this, it’s pretty long actually, and the guys were rigging it off the side of the boom, really short stubby jib here, and, the bales were set pull up one here, and one here. And the center of gravity was not really well regarded and what the guy did was to rig this up in 2 inverted baskets. 2 to 2 pick points, 4 pick points on a bale. They ended up with let’s say as sustain came off, of course, crane hook is right here, picked up, and they tried to pull it off the side of the crane, this way; and just the second it left the engagement anchor and hangers on that crane. I’m sure that what you already identify is: this is end up dramatically, this butt section went down, and the slings went right through the hook. And unfortunately we have a gentleman who was at this end of the jib hang on to end of it, pulling it away from machine, and he was injured as a result. So this entire unit went up and flipped him, he’s been injured now as a result, of this. Inverted baskets are just a killer way to rig, I mean it’s not good, it’s going to end up and people hurt in hurry. I had somebody tell me don’t worry the load self-centering. Well that sure will, it do exactly what it wants to do, and it want to be really cautious, so, not put a big circle in slash over this thing here. This is not going to be simple we’re going to approach, and any, really easy way to get hurt, fast way to have a wreck. Let’s take a look at number 2, we’ve got A) or B), and we think most of you have marked B as the prefer method. Think about that east and west control, and then north and south control. That looks good. Sort of this, optimum angle right here, that we want to be greater than or equal to 60 degrees up here, and that’s from the south west corner to the north east corner that it’s serve as our imaginary line right there. So, we’ve got a double wrap on each end. Closuring together those 3 pipe units there, that’s really good method, and nice toll angle and everything, works best for us. Under 2A we’ve got a number of issues here that inverted basket. Let’s go back to rigging card. And bring up on rigging card; let’s take a look at those sling hitch types there. And I’m going to put up little cleaner, cleaners series for us. Take a look at those hitch types there, and if you’ll notice, we’ve got that inverted basket right here, number 14. And right below we’ve listed that as a number 14, single inverted basket, above the center of gravity, 2 legs are taking load, but it’s very much upon load control poor method for rigging. We’re looking for rack, we’re getting through that rigging, and that type configuration and you want to be really cautious, and avoid that at all causes. Just a lazy ware rig and just, this is a big no. We’re going to lose this in a north and south direction for sure. And I would certainly say with this angle coming down, going across to the cross corner, and back up, that angle is very flat right there, probably in a 30 degree range. We’re very  flat, really good opportunity, for those slings to slide in, and once sling slides in, the pipe units can go oopsy-crapsy on a steer, and we lose the whole bundle, so, we’ve got bad rigging really, that’s a top and a bottom. For this method it would be really poor way to approach a load, it’s really pretty lazy, we just don’t really have attack properly, and  we’re not taking care of rigging, and technique itself, and our load control. Let’s take a look at 3A or B. 3 A, we’ve got, this is, if you look on your rigging card on panel 7 and 8, then for the journeyman on page 3 you’ll see this as hitch number 8, and this is going to be hitch number 13. If we have valued those 2, let’s take a look, I think we probably all agree, let’s go with A as our preferred method, east and west control, north and south control, and look pretty good. This, this inverted basket on this one, is a really actually a help to us. If you think about it; this inverted basket to the left, we’ve got 2 short legs on one side, and let’s call that 8 foot and 8 foot, and this would be a 16, and then inverted basket always makes sure we take a care of D to d raised, right up here, where the sling is going overthought, unless you’re using synthetic rigging with the ware path or protection. The make sure that this will help equalize loading all port pick one; and it’s really good way to help lower the loading and tension per leg. The tensions going to be also pretty equalized on B, however, this is okay, for east and west, but boy, this is a disaster on north and south, because we’ve got these inverted basket doubled  and we have a really dangerous  and hazarders method, if you notice it’s number 13, on our page 3, we’re listed as 4 legs take load but it’s very poor way to rig, it’s not something we want to get into, and that’s from ours illustration right here. We want to really be cautious, that number 13 as, no go, that’s a good way to get hurt, so, go back to our schedule quick here, and let’s go to item of number 4 here. And this is pretty interesting, this is a method that can be used for A or B let’s take a look at; I would help most of us to select A as a preferred method. Let’s talk about its attributes, for a second. East and west control looks good, north and south control looks pretty good. I mean it’s all a texting right up there is a hook, given angle or lengths to height ratio, and tension. We might only get this credit for 2 legs take load, some folks will take 3, rarely when you get 4 legs taking load, because of pick point placement, point length etc. So, rarely we get all 4 legs equally, taking load and that might not, but, from the control stand point, we got it. We’re in good shape. This one over on the right here on 4 B, let’s take a look, east and west is probably not a problem. North and south, that’s our problem, and we’re doing a couple of things here. One is the sling connectional run through those shackles. Those are running basket hitches. They’re actually reach through the shackles, and pulling against those path, so, we are the run ability here, is an issue, but  even bigger is the loader forced is being imposed on a corner pick points right there. And if we take a look, we actually have a little bit of included angle right here, and I’m going to ask you to go with me to your journeyman rigging card, on page 3, let’s take a look at that guy. And let’s look in the area that’s called Block Loading, and Block and Fairlead loading. And so, if you remember that, those slings are breaking through, the pick points, and I’ll just try right over the top here, sling is breaking through the shackles and breaking back up. So, it’s actually that shackle for dead end connection right there, and right here, serving as a little baby rigging block. What happens is compounds of loading right here that, shackle connection and path eye really dangerous way to rig, and we called this angle right here, 60 degrees from minute, and if you’re notice right on your chart rate there, at 60 degrees, angle, full angle included right there, we have block factor of 1.73. And so, what we’re going to do? I’m going to go back over through drawing, and let’s apply that, now it’s knowledge, and we’re going to give this load, we’re going to say that all pick points are going to be 3000 pounds, and do the same thing on the other side. If we have a perfect rigging method, and all 4 legs are perfectly equal in length, everything is good, and a pick points are right, we could float that up at 3000 pounds, per leg, especially if we had sub links and master links upon the top of, and so on. We’re able to float that up properly. If we apply that 3000 pounds over here, 2 of those path eyes and shackles right there , what  happened is, we’re going to, we’re going to apply that 3000 pounds, dedicated load to that sling leg, and we’re going to use that multiplier , and I’m going ask you to [Inaudible] in your calculator in your telephone, there,3000 in a multiplier for a 60 degree angle right there is 1.73, and we’ve got an actual load on the pick point, on a baring point,51. 90. That’s the compounding in fact, and that’s happening right down here, at the shackle and lifting load. It’s no longer, just 3000 as we have on the left hand side, on 4A, it’s actually almost 5200 pounds right there, on each of those pick points, and we’re trying to pull that path eye over broad side, it’s an orientation likely would not never designed for. I’m just kind of put big word lazy here; it’s really a lazy weighted rig. We need to actually improve that, and make sure that we’re not compromising the path eyes, pick point, and not inter vertically increasing detentions, of those. Be really careful, this will be another of those: “Boy stay away from that, like in hearth bit.” It’s a good way to get hurt, so, path eyes can snap off, and the loads can come down. We’re going to look at  last for some files B, and  let’s take a look, I hope most of us were preferred B, east and west control, north and south control, looks good there on 5A.We have , in this orientation we call this east and west not bad, but boy it’s a manning  it here for going north and south. And that one thing to think about is CG is up here and going across to that other sling condition, in baring points below the CG. We have 2 legs, below the center of gravity. And it’s a perfect recipe for disaster. As same as a couple of times, guys were rig this up, and think it’s all happy and nice, and lifted straight up and it doesn’t react, nothing happened. But eventually that crane has to take side way. And when we’re go sideways left or right, that load just try to decide why fall to the fort side or start up side and we up at below, and all the sudden cut the slings, drop the load, everything goes [Inaudible] on it; really poor way to rig; a reference point for that on our card, if you take a look at, this is number 2, and we’re on page 3. Look at hitch number 2, right there, and just as a point of the information, right down below you’ll see these 2 legs, right, or right here describe 2 legs, right over there. [Inaudible] below center of gravity, it stays above. Two legs and average load, but his is limited to above the center of gravity only, never below CG, two legs never below the center of gravity, not a good way to rig. All right, let’s take a look then, let’s go for next workshop, and we’re going too plugged over to a page 6, and this is a great workshop, I’m going to introduce you to couple a places on our rigging card. We’re going to work through this together; for those of you, as we can build this together. I’m going to bring this sling a large at the screen, and this is sort of a walk and talk together, and , we’re going to identify the first of the total way, right down here, so 110 000 pound. And you’ll notice right below that, we have, ware component, A, B, C, D, and E. So, we need find out what size the components needs to be. And right down below, we need to figure out participate in tension for all those components. So, let’s go back up, right those down as we go. We have nothing to the alternative but the engineers that assure us that the path eyes are the proper to place too according the center of gravity. We all get there, we have equal distance this equals there, this equals here. We’re good there, so we’re going to anticipate and sure that any small rigging way, 55000 pounds, for path eye, so let’s make a note there: 55000 pounds per path eyes, anticipated tension for A, and for B, and for C. So, I’m going to write that down below, I’m going to inner that as my anticipated tension area, so please do that with me, right down here. 55000 pounds, for A, B, and C, because I have to size my rigging up just a few minutes .Now, before we go over to picking a rigging and it’s available capacity, let’s write that all of our tensions first, then we’ll go and pick the rigging, to accommodate that. What we told then, we’ve got, the next tide them up, we’ve got the lifting beam, spreader bar, right here, and that weighs 10000 pounds is good for 16 ton. So, I’ve got account for the 10000 pounds of extra load that happens at this elevation. So, right up on top of this path eye, right here, it’s got that load of 60000 pounds, straights up, for each in because I’ve got my 55 plus 5 000 at this end of the bar makes my 60000 pound. But my real question is: What is tension? Going up at that leg, that’s really the bigger question. I got to accommodate my rigging from my tension. So, we’re giving this 45 degrees right here. So, here’s a card that we haven’t use yet is on panel 4. And that’s the master rigger card. Let’s take a look at that guy, on panel on page 4, master rigger card, is in the upper left hand corner of the page. And let’s find the 45 degrees, right here. And we have, what’s terms lengths height run relationship for 45 degrees is a length of 1414 heights of 1, and run of 1. So, really, what we’ll do is we’ll take lengths divided by height, as our multiplier. Length, divided by height, is our multiplier time share of load weight. And that formula, if you want to find that formula, it’s right on the journeyman card which is on page 3. And that formula is on panel 2 right here. So, we’re on page 3, second box down, said  Load Factors and Weight Distribution, and that formula is right her on the top. And a formula says the length of the sling, divided by the height, time share of load equals tension. That is how we apply length over height, and that’s a formal location on our Journeyman Card, we’re using the number right up on our Master Rigger Card, so we’re going to using that, 141, 141, and the 1. And so let’s go back to our workshop page. I have, I really in my rigging  drawing, I don’t know what that is , or  that is, but I know that’s a 45 degrees, so I’m going to have 1.414,divided by 1, times share of load of 60000.Now that help me find what my tension is, so I’m going to  punch that into my calculator, let’s do that 1.414 divided by 1 is 1.414 times 60000 , and let’s get we’ve got 84840, I need to inner that, I work on page 6 right here, so I need to inner that, for my tensions, and anticipated tension is 84 840 for each of those 2 pieces of gear, my shackle, and my top sling. So, now I know my anticipated tension, which I always need before, I can take my rigging. Now I’m going to show you really cool place in our Master Rigger Card, that get us to some really quick planning decisions, how bigger rigging do we really need? And that’s on the Master Rigger Card that’s going to be on page 4,page 4, and I’ll show you on a big sheet, page 4, and that will be over on your right side, and it’s going to be this panel right here, In-Line  Tension Capacity Chart. And it’s really bowling down whole bunch of rigging charts and putting in to half of panel. So, I’m going to focus on that for just a minute. So, let’s use our decision going right there, so In-Line Tension Capacity Chart, we’re using this panel right here. And we know that we’ve got 2 sets of tension we’re trying to overcome with our rigging .One is 55000 pound, and the other one is 84840.So,I got to pick my rigging to accommodate that. Question A is: What do I need for shackle, load shackle at 55000 pounds? And I can slide down that little chart, and identify  I’m going to come into the 60000 pounds, point, right here, and then I’ve got a box to tells me my wire ropes slings, or web slings that are flat endless. I’ve got chain slings, and I got shackles, right here. So, I need a shackle, and I’m going to write in that 2 inch shackle, for A, and web sling, and let’s flat web sling it’s going to be description of our tree, triply 9000 pound grade webbing 8 inches wide, and that’s  B, and then C is going to be another tool and shackle again. I’ve got A, B, and C identify right there, and lot of times manufacturer can pull over the web sling and make it more suitable for barring into that 2 inch shackle. And so that down forest or we can also use the wide body shackle potentially, for making up that connection. We found quickly, we need a couple of 2 inch shackles, and we need that 309 web sling. Let’s transfer that to our, workbook page, so we put that right down. And we’re right there, so let’s get that listed, and get that taking care of. Some worker thanks for writing along with me on this, page clipping, so I got to 2 inch shackle, and EN it’s a web sling and it’s a 3908, and I got another 2 inch shackle here. And we reflected, we found the capacity for those…at least stated on the card is 60000 pounds, minimum, and actually if we go to our ready capacity table we’ll find opposed, that probably have some prior capacity. But that’s available based on the Master Rigger Card. We know we, because it’s always a double check. We want to make sure that each of these 3 decisions exceeds, then anticipated tension on this other side. We’re in great shape there, now I got to find some bigger rigging to handle the upper sling and shackle selection as long as top side. I got to deal with that sling and shackle combination which is D and E, anticipated tensions is going to be 84840.Let’s go back over to our Master Rigger Card which is on page 4.We’re still on that little panel on A right there. And I got to get up into the next bunch of rigging sizes here, and 86000 is our best available capacity to overcome 84840, so I got my wire rope selection, and my shackle selection. What do we find for shackle size? 2-1/2 inch. What do we find for the wire rope sling? 2 -3/8. And its best known available capacity is 86, and both pages are probably over that, but that line in a send we’re able to build into the card to help give us some planning tools for selection. So, let’s take that information right over to our, and we’ll complete our 5 point listening here. I’m going to use the 2-1/2 inch shackle, and at the moment, I know that it’s got at least 86000 pounds, that’s a columnar chart point, I found that in. And I can use the 2 -3/8 sling, and again 86000. And this and this, both exceed, aren’t anticipated tension. So, as certain, size of the rigging will may have to be added rigging weight, I don’t think we need to disappoint, we won’t beginning , that much rigging way above. We’ll be at least, right up and above [Inaudible] capacity. We just found a number of quick solutions, for that little workshop problem, so, we’ve got, we know we’ve got appropriate rigging for all of the necessary components up here, for the 110000 pounds vessel, and so, we’re using the 2 inch shackles there, and here, 3908 web sling En, for endless. We use the 2-1/2 inch shackles down here, and 2 -3/8 at least wire ropes sling out there. Always making sure that the sling, make sure that D to d ratio will never get that crossed up with the shackle that we’re selecting. We’re in good shape, there. Excellent job, everybody. Let’s charge into our last workshop, this is, this is really a kind of a cool little, identification. We know what the weights of each component are; we need to find that combine center of gravity of this, other guy. And think the easiest thing to do, and let’s just sort of, we’re going to marked out, for moment. Now, you have, a little bit of your ruler on your Master Rigger Card, on panel 4, out on the edges, you’ve got some marking indications out here on this side, and with item that we were able to send you, we weren’t able to transfer some of metrics, some of material, and of course [Inaudible] but just grab a ruler, or… I use the metric ruler or, doing a lot of this. Grab something close to handy, you can also use this, tear that page off and use this for indicator marks, and we just set up this working in unit, and I get you the solution as we go through it. What we want to do first is, we’re going to identify the leg per section, and we notice right here leg A who is 3000 pounds, leg B, is 6500 pounds and leg C is 5000 pounds. So, A, B and C, those are the weights of each of those pipe sections coming in. Pretty large seminar very light wall, need to find combined center of gravity so can pick thing up and down it, just we planned it, so, we need to find the worth to combine the CG of this particular load here. And what I want to do is  suggest to, is to take a look with me, on the, the simplest thing probably  is just grab them , the Journeyman Rigger Card, on panel 3, and I’ll helps you with… you’ve got … that would be the easiest approach that we can take in this case. And in panel 3 we’re in a left hand column, in the load factors, and weight distribution section. So, find your page 3, left hand side, and this is a second little box with data down there. And what we’re going to use let’s use this known weights formula right down here. And that would be the easiest thing for its to help us, we realize and see on that known weight formula we’ve got a weight over here on the left side for this little example and away over here on the right side we don’t know where the center of gravity is, but using those 2 weights help us arrived at the CG. So the center of gravity, we’re going to use these 2 formulas right here. Center of gravity in feet from A, center of gravity in feet from B, and we’re going to find out where is the Cg for 2 pieces, then we’ll take that combined CG go to the third piece. It’s actually got to go pretty quick, but what  I want you to do is turn that page off, we’re going to use that formula, and I’m going to put it up on the screen for us, we’re going to work through that pretty quickly. Let’s take a look at our task here, and one thing what we want to do right after that, is to use the straight edge, and just draw a line from what we’re going to marked out is A and B, right here. And we’ll just make a mark here. From A to B, sorry about the ... I make a clear mark, I just free hand this. A to B, and I’m going to use matric on my screened page, that you should also have, I want to [Inaudible] up my copy machine, I got that distance, and I’m just using millimeters to help for quick reference, is, I’m going to ,I call that 42 millimeters. Just picture a scale, whatever scale you want to use, and I’ve got 42 units; from pick point to pick point, from center of gravity to center of gravity. I need that piece of information, because I’ve got to insert that just for few minutes. Right, so we know that leg A is 3000, leg B, this center pipe section 6500,so grab yourself a piece of paper, and slip one of these pages over on the back, and let’s  write that formula down, and the formula from this page 3 right here, that formula section known weights, that’s where we’re going to work from, let’s just grab blank page here, and we’re going to slap the formula down, so the CG  in feet from A, and from B, let’s work this together, so weight 1 . We’re going to assign the weight, W1 and W2. So, let’s do that. I’m going to make this A in W1, and make this B to W2, and the S, equals 42 millimeters. So span this 42 W1 is 3000, W2 is 6500, so let’s just establish that first. W1 3000, W2 6500, and spans 42 millimeters. So, let’s pick up the clean [Inaudible] here, and work this out, we’re already quick. I’m going to write this, and leave plenty of room to fill in my actually data in between. I’m going to put this up like W1 and W2 is equal to total weight, of the 2 pieces combined. Then I’ll take W2, what the formula tells me to do right here, W2 divided by total weight equals to percentage, and then percentage times for S equals CG, in feet from A. And, let’s write in the known information that we have. What is weight 1? That’s 3000. What is weight 2? That is 6500, our total is 9500, excellent job there. Let’s take W2, which we know that been 6500, divided by 9500, that’s going to give us the percentage and that percentage; we’re going to, around that out to point 68. Good job there. And, we’re taking down to the third line, point 68 times S, we establish that 42 millimeters, or feet, etc. Then we’re going to get… we’re going to get out of that, we’re going to get 29. And now I’m going to call that millimeter, and so, I’m going to go back to my little drawing. And I’m going to measure out to about the 29 millimeters from A, using kind of my skill. And I’m going to write that point, right about here. And so, I got 29 on this side, from A .Now let’s do our B side, what I don’t know is to double check on that, and then make sure that I can get this correct. I’m going to do how far from B, let’s put that in. I always make sure, just like I did back in school is to make sure I’m going to work both sides of equation; and, capable confirming it from both sides. So our second formula is W1 divided by total, equals to percentage, and percentage times S equal’s feet from B. All right let’s slap our numbers in. So, I’ve got again 3000,and 6500,equals 9500.Now this time I’m going to take weight long, which is 3000 divided by my total weight of 9500, and I’m going get that around number is going to be point 32. I take 32 percent of my S of 42 ,and that’s going to give me 13.All right, so here’s one question is, this 13 and 29 get us back to 42 and complete answer is yes. Let’s go to our drawing page, and so, I got 13 from one side, and 29 from the other, and that’s going to get me now that combined center of gravity is right above there, from those two components. Now here’s something that we want to take in consideration, I’m going to take all this other stuff away from that, and that little red CG bullets right there, and that is combine center of gravity, stuff A and B. So, I’m going to because I have the magic pen here, I’m going to take these all away out, they don’t actually exist anymore, because we’re going to be collected right there at this bullet point. This is going to be my new B, my new A, that center of gravity is going to be represented my new A, and that’s going to actually represent 9500 pounds because they have my 3000 and my 6500 became that new CG bullet. All right? So, A there, in that case is going to be 9500 because I’m going to ask you now to find the combined CG of the entire load. Now this collection point is new A, I’m going to get rid of the load designation C down here. And this lower guy is going to become B, this is weight 1, and weight 2 equals how much?  5000 pounds, excellent, all right. So, W1 is 9500, A, W2 B is 5000 pounds. Let’s use that formula again, and let’s measure this distance, and let’s see if we can get an agreement here. I want you write on that straight line, right in there. If have a value that I came up with but I didn’t just prior to workshop studding, and I’ve got S equals 58 .So, we’re going to call this entire S right here 58, so I’ve got my 3 pieces of information because I’m looking for where is the combine CG? Now all 3 pieces have together. Let’s get new clean page in front of us. I’m going to keep that data there, so, let’s keep let’s get a new page here. And I slap one up on the screen. So, I’ve got W1, plus W2 equals total weight.W2 divided by total weight equal percent, percent  times S, equals CG in feet from A. Do the same thing on the other side, for B. W1 plus W2 equals total weight, this time I use W1 divided by total weight equals percent, percent times S equals CG, in feet from B. All right, so now I’m going to give you a few seconds here, and think what we can come up with, our total combined center of gravity, let’s work those up based on the numbers. I’m going to just put the initial numbers in here, this W1 is 9500, W2 now is 5000, and we should end up with total weight, and excellent, we got 14500. Now let’s drop down, we’re going to impose, employ our formula here 5000, then divided by 14500, and this by rounding, we’re going to get that value of point 34. Very good, point 34 times S. What was the S we called out there? We said it’s going to be 85, just by scale, and now we going to end up with about 20 millimeters or scale over the feet, and so on, that’s good for 20, a unit of 20, and 20 units from A. We’re going and put that on our drawing, just a second, let’s figure out our right side. Work very quickly, [Inaudible] so let’s go with 9500 doesn’t change, notice our 5000, and that’s a 14500. This time we’re going to use 9500, divided by 14500 equals a percentage of 66. And now put that 66 times my S of 58, and then let get me down to 38. Here’s the question again: Does 20 plus 38 get us back to 58? Absolutely. All right, so let’s go back to our drawing, and put our values there. We’re going to measure a long, that line from there, to there. And we’re going to go 20 units from A, and 38 units from B, and our CG is right about here. So, 20 there, and 38 here and there is our combine center of gravity. Now why is that important? We want to be able to rig that load, from almost any orientation. I’m going to start taking some information down here for just a minute; because we’ve got some nice information to then make probably 5 rigging decisions from. So, now we’ve got a total weight, we know our total weight is 14500, we know our center of gravity. Let me get rid of these other little guys here for minute. There is our CG. CG doesn’t have to be hard point on the load, it could be uploading in space .But it is D point about which to rig, now we can decide, we want to decide to rig that up from the top down. Just assume we’re looking top down right here. And we want to build a triangle to support that load to flat. Flat out some [Inaudible] and put it, and engage it. So, really what we want to do is to start with that little center of gravity, and what you can do is, I know that sounds little silly but just draw a ring around it, and draw another ring around it, and draw another ring around it. And at some point what we want to do, is find that ring .Where can I rig this up, so that I got some support creating a triangle to support that load. So, I’m going to get rid of those, just for a minute, so I got my 3 pick points, kind I identify there. So, I’m going to rig potentially from here. Here’s my center of gravity, rig that up, and then right this up, and rig this up. So, these are 3 slings, or 2 slings, and 2 chain falls, with other slings below them, and I rig maintaining that load, within that triangle. Those[Inaudible] legs are equal, that’s okay, it’s not shape load, it’s not  odd small weights I’m really dealing with, but if I’m going to rig that straight down, I got the loads considerably, I can move this sling down to this position, stretch that triangle out little bit. And little better load control, or load distribution. So, that’s from the top down. I just, if that’s my center of gravity, I work my way out to 3 barring points that I like to pick that up with. Let’s take a look, we want to up in that load, and let’s put the CG back in there, so we’ll put that center of gravity right back in her for minute. By the way, when you measure that out, I think I’ve got 52 units about 52 units from the top, north edge, and it’s ended up with 24 units, from the east edge; to see if we all end at the same place. So, let’s just a double check, 52 from the north, and 24 from the east, but here’s the idea. Till we want to up end this load, and here’s what I want you to do: take that center of gravity and sort of take a line north and east and west, and north and south, so if I want to rig this up in this orientation, I will pick my slings, and so I can listed up this way. And knowing that center of gravity make a subtle mark right on that type right there, go equal distant, equal distant, I can rig this up here, rig this up here, and my  slings will meet right on that CG line. That’s good, now [Inaudible] in that orientation, I can certainly do in this direction, make sure your slings pick on that CG line, and certainly I can even do it from here, come around, and unpicking over the other direction. So, as longs as we got the center of gravity, identified, we can take those slings and make sure that they meet, at that orientation line, right over that center of gravity. No matter if it’s north, south, east, west, top to bottom. And you got that load pick, then we’re able to control it, but it’s all about where in the hack is that center of gravity. And that’s how everything works, that’s how make everything come together , and we’re controlling a load, we’re making it and do what we want to do, and not being in its mercy. All right, Zack thanks very much for let me go through the workshops, and I’d like to see if we have some questions, that I might be able to help answer, and let’s see what folks says on. And looks like we have a great bunch of folks that are stayed with us, all the way through. Everybody you know, high endurance, and doing great, sure appreciate for participation, so let’s see if we got any questions, today. If not we’ll be rolling out, and then moving on the other items. What questions might we have, Zack?

 

Zack: All right, we’re all, let’s answer to the questions we have prior to the event starting, but also everyone you can, so, make questions on the discussion and the chat box on the right; reverting the workshop that you saw.  Question from Roman: What is the best rigging technique for casing pipes?

 

Mike: Well, you know, and I assume that lay up and stand, stand up, and if we don’t have welded lifting legs on them, which would be optimum. We always like to have pick points welded on the top and we can come up with 2 slings, and then pick, and then rotate that up, if we don’t have that, welded [Inaudible] on some block, and that’s always important, let’s block these things up, and make sure you’ve got them supported off the ground. So, we’re able to rig down on your knees, but quite often we just need really good, high capacity sling, I would always push for using a small spreader bar in this case, but what is not uncommonly done, and you can rotate right on the chocker hitch, is, and we were produce a couple of double rack chokes at this point go up and make it half a hitch. And it’s still rated as a chocker hitch. And make it such that the sling is binding in, into the turning direction, so you make him one half hitch right there, and that sling brakes around, and goes up to spreader bar, and that’s spreader bar only needs to be just likely wider then pipe. And do the same thing on the opposite side. We have choker hitch started on the opposite side, and it’s rigged up and it also has that half inch choke point. And it comes up on the left side.  And then rig up to our crane hook, that distance right here has to be high enough to pass to the top, as we stand that up and inverted, and we’ve got securement down here with the double rack chocker hitches, down here for securement, and then half hitch for [Inaudible] and rotation, and then we’ve got a spreader bar to be able to use keep the slings away from the cutting edges of the pipe. And then, as we lift that pipe up, and if making its rotation, it’s rotating about those pick points, and it’s able to clear that top of those as we take it to a vertical position. There is a number of ways to do it. Wire rope sling certainly will work D to d ratio, so that can be a problem, but synthetic regional work as long as always make sure we’ve got the spreader bar in there, and then that keep the slings away from the edge of the load, if the pipe turns up and makes its rotations so we can stub it. So, I hope that help, and there is a lot of ways to do it, but the double rack chokes, and turning hitch right there, that half hitch will help get the job done. Great question Roman, thank you very much. Any other questions Zack?

 

Zack: Yes, let me, it’s interesting question, actually out of New York, from Conn Edison, Handy put this in before the  event sort of :Is there, is this Master Rigger Course specific to any state or cities like New York?

 

Mike: Great question, and answer is no. The ITI Master Rigger program is… what you want to, kind a notice this skills building program, and knowledge based, and knowledge enhancement. The New York City Master Rigger Licensing, is really its own [Inaudible], and if will [Inaudible] some of these subjects that are covered within this course, it could be considered about 50  percent prep course for the New York City Master Rigger Licensing. But they add into that a number of other elements that have to do with crane rigging, erection of cranes, and a number of other subjects, that are really restricted to the New York City license thing. So, it is a prep course, but I would only want to tell you that I would say, hopefully about the 50 percent of the content here, will help with this license thing exam. The other 50 percent are other subjects that New York City has developed as a need bases for Master Riggers to assist and add in correction of this mangling the crane. [Inaudible], all kinds of other things, that they decided that the Master Rigger has to be a knowledgeable about; Good basic program, good skills building, but it won’t, we don’t cover the entire breath of all the things covered on the New York Master Rigger License stuff. Great question thank you for that.

 

Zack: All right, James from Argon National Lab, actually have the follow questions that’s similar regarding the credentials obtain for the Master Rigger program. Are they recognized, in the US, or how and, broad?

 

Mike: Great question: right now what I’m going to tell you is, sort of in the US that I know of, except for New York City, which got a particular test, and it’s only good for New York City, but all of the programs right now are voluntaries and layout. So, wheatear folks go with the basic rigger, signal person, and those are required trainings for construction of course, and  qualification as required  for constructor activities, but there is no, you might say certifications are not required but qualification is required, on the Advance Rigger , the Master Rigger, it’s all voluntary as well as Lift Director . And what we’re going to, I think we’ll see in a next few years probably  in a 2 to 5 year window, of course we still have the rigger qualification ,and signal person qualification, for construction that were going to, we likely be seeing Lift Director as probably the next certification that would be out there  and available. But I got to tell you, lift director mentioned by notion in a new construction crane code, but it’s not certification as required, but their employer have to insure that their concept first is to qualifier to perform that work. But I would suspect there would be at least 2 organizations that will have certification available for Lift Director. And that would be on voluntary bases. I don’t think it’s going to be certification and required OSHA, but only folks [Inaudible] verified by the employer. Lot of these are going to get down to the employers, designate an unemployed have to have a concept deep level, to certain status within the organization, but they basically be doing that to prove to notion  that  by written testing and performance they’ve got folks that they believe are capable and constant to perform  certain work activities. But from the certification side of the world, I don’t see it right now happening. A lot of private companies are, of course have certain level in tears, rigging super intended, lift director, all those kind of things for BP, or Shell, or for Los Alamos, or for all kind of different organizations they have variety of titles, but almost all in house corporate designation they’re not based on a national standard, or national accreditation process at this time. We’ll see a lot of activities starting up and competing in the next 2 to 5 years at least throughout the US [Inaudible]. Next question.

 

Zack: Yes, that’s good, and one little saying on that, maybe for you Mark from [Inaudible] asks: What the new OSHA standards requirement of the qualify rigger, what amount of training has been discussed, maybe we can add on, just finish of that subject so we can jump back in to the technical questions.

 

Mike: Yeah, you know what I would have to say for the qualified rigger status it’s really the ability to perform and OSHA really is, and what OSHA is doing a lot of times its showing on a site and they are actually, it’s not so much: “Can you hang slings on the hook and then the shackles and then pic the load up and go with it.” It’s what is the load weight? They are asking very pointed questions and if a rigger is not able to answer that and he is not able to compute or calculate that then OSHA is going to say: He is not probably qualified rigger.” They are asking questions: “Where the CEG and what is are the sling tensions?” And what’s happening, I know on a number of job sites, they are asking those basic questions the qualified rigger and if he is not able to respond intelligently and reply: “Here’s how I figured the load weight, here’s the approximate center of gravity and here’s my result in sling tensions.” If they are not able to respond with that OSHA is taking a very hard view of this and saying: “Well that’s probably not your qualified rigger. Who is the next person?” So That really is achieved most of the time by, and so to get to the ability to perform typically training is involved, experience, knowledge’s is gained and putting it into practice. So we now that that’s how we get to this ability to perform is by having this building blocks under that person that OSHA only calling out that ability to perform and the way they are checking that is face to face questions of site employees on the rudimentary basics of rigging activities and they are, I have seen them deny on site rigger and also in numerous cases and signal persons that are not able to perform according to the requirements and they said, basically my [inaudible] employer that are not able to perform an answer for these questions so we don’t believe that they are competent person, the qualified person for this task, you need to get another person and I need to talk to that person. They are going to go right down the list again, so I got to, you know, I am not throwing, sky is falling here on top of you, but training is a huge leg of that. And once one they get that training and knowledge, like being able to use a rigging cart the way we used this morning and then put it into practice, experience, gain that. Generally speaking a guy needs to be trained to probably one level above what he really is performing so he’s got at least some of that exposure to that next level of information. You got some high in Journeyman Riggers, qualified riggers, some exposure to the Master Rigger subject, is really valuable. To get a Master Rigger, some of the exposure to a lift director, is information is really helpful for Master Rigger. Once you get to that level, some of the exposure to that next level is up, is really important for them to be able to see how all fixed together. I hope that help answer the question, I don’t personally know how you can get the training [Inaudible] in there, to not help support the performance, but a lot of employers are trying to do that, and they are not very successful  at it today. I am seeing citations coming out because of that, and we need the training leg underneath somewhere , whether in house, or out house, third party, whatever they got a from, there is probably going to be  training support that ability to perform. Great question, thank you very much for that, let’s go to the next one, if there is one.

 

Zack: Yeah, there is a few technical  questions here, came on  during the webinar, Richard Kravendam he asks: When you have the 50000 ton load, and lifted with 4 equal length slings, what’s safe working load limit slings do you need, when this angle with the[Inaudible] 60 degrees?

 

Mike: Okay, I think the big super question is we really counting on 2 leg lifting, 3 leg lifting, or 4 leg lifting. And if the assumption is ,we’ve got 4 legs actually lifting, you, and Richard has this up for 4 leg left, I believe  right?4 leg lift with 50000 ton. And really to achieve that we got to have some equalization, and so, I’m going to draw in here a master link, and a couple of sub links to try the help equalize the loading. We end up with hitch point the various locations. And then we come down with 60 degrees in this question, and this is a little [Inaudible] I know Richard’s capability and skill level. There is no [Inaudible] for the professor time for Richard, he’s much more professor then I am. We know that loading, the apply loading if we take a look at the Master Rigger Card, our 60 degrees, we know the load factor is 1.155, so, it’s 60 degrees right here, the load factors just about 16 percent, and so we go back and, if we take Richard giving us an example of 50 tons, and so we’ve got 50 tons on the load, and if you really do give it up, here for, most people won’t do that, and I agree. But we’ll use Richards’s comparison here, and so we’ve got a vertical leg loading of 12.5 tons, per leg, vertical, and multiplier, we just found out over on the Master Rigger Card, times 1.155,so, we’ll impose that. And so, in line tension right here we got 14.4 for ton on the sling, and of course on the shackle connection point, or about 15 ton. So, that’s about, so we would be grabbing 15 ton shackles, 15 ton slings, to be rig in that leg position right there, times 4 to work away around that load. That only satisfied if we are able to divide the leg loading by 4, and end up with appropriate, minimum rigging, that would be 14.4 ton rigging and slings and shackles. Obviously Master Rig got to be all prepared the entire load, up here at the top, this entire establish got to be suited for that 15 ton to be able support the rigging that’s coming up into the bottom of it. If we, the other way certainly I know, 2 companies personally, they take 15 tons divided by 3, and most companies that work to the really high ends for a safety, will take this 15 tons divided by 2, so then end up with 25 ton anticipated, vertical leg loading times 1.155, and then end up with, I put that in one point, they put in 28, or 29 tons, and that would be 28. 87 tons, or 29, or 30 tons per leg, they [Inaudible] on 2 legs doing entire left. And, make sure that they don’t get over laded on the rigging. Great question, Richard I appreciate it. But that Master Rigger card, you know, I got to tell you that that is a super little chart right there, for arriving quickly load factors, based on a variety of angles. You notice that those go anywhere from 90 degrees down to 0. Look at the load factor aside degrees that were on below factors 11 half, almost 12. So, it’s huge, so it’s really great tool. And, feel free to use this paper version you can certainly buy the plastic, and laminated version from the book store, but this is really, if you take the time really good answer,  that subject  items goes through the different components, you’ll find this really super card, or making  rigging decisions simply in a field. Any other question Zack?

 

Zack: Yes, there is a few more, and Richard, this might deserve just quick answer, but Richard was questioning, all your answering there, is there rule anywhere specific that safe you must use to  for your 4 slings.

Mike: Not in my knowledge, I noticed, it normally will end up as a corporate decision, it’s a great question, so, using a 2 legs, or 3 legs, or 4 legs, wire rope sling sellers and web sling, and round sling, folks [Inaudible]based on the 4 leg capacity. When they market 4 leg items in the US and Canada, the best of my knowledge, their market is for 4 legs taking all, and sharing all parts of that load. Obviously the Alloy chain folks limit their 4 leg, and 3 legs to only 3 legs capacity only, and that’s pretty standard in North America. And then a metal mashed slings, work on single leg capacities. I need to throw in here rope slings, synthetic rope slings all over here in the 4 leg as well. One leg, or metal mash, because they’re really only designed for basket choking, and that’s all the permitted to the use. It could be used as spreader bar, but they’re not incline angle loading because there are profiles that metal mash won’t permit that. The, I would say that corporate is, it is our corporate position as well as probably 50 percent of our corporate clients, restrict themselves, to a 2 leg, lifting. And, so they, that is a practice, but it’s not really an OSHA regulation, or ASME document to my knowledge. Maybe the API document, or Singapore requirements for MOM [Inaudible], or Australia, may work at different design factors, or different leg loading for maximum permissible. But it will be like country specific indoor my corporate. Great question and I appreciate that. Go ahead.

 

Zack: Okay, we have 2 more questions that are…

 

Mike: All right.

 

Zack: Dale Thorton from, [Inaudible] What do you think of using both hooks on the same crane to up in the pipe, or taking just describe in workshop? Many folks are against using the weep line on the tail. When up digging all capacity being within charts.

Mike: Okay, very god question. And under for ASME, this 30 point size, the current edition I believe 2011 edition, they are in current discussions that that does not address, this kind of addition does not address that there is new, there are new proposals currently under discussion and that just strictly proposal format for using both main block and axillary block for up righting loads, and I can’t tell you at the moment whether it’s going to survive the voting and it’s going to be, probably, another 3 years before we would identify, what has to happen here is it ends up going thru the point 5 subcommittee, it comes to the ASME the B30 main committee [inaudible], if it can survive there it will go out for public review and thru the [inaudible] approval. OS we are many steps away from actually getting that done, but I will tell you it is absolutely hot topic at discussions and what I think they are really proposing is that you must have, to make this happen you must have load indicating device, whether in the crane or on the hook and that the will or, at the option of the operator to be able to, be able to identify and determine the actual payload weight for each hook. So what they are doing is to make sure you have got a crane scale load, load moving indicator LMI, dynamometer or something that you can have at will, punch a button and find out what’s on my lip line, punch a button what’s on my main hoist. That is the approach we are trying to take right now to help protect. And you must have a [inaudible] that must be Okayed per the manufacturer to use a crane in that configuration. Some will say yes and some will say no, so based on the crane and it’s a position, configuration, some manufacturers will say: “We will give allowance for that two cranes or two hook tech and turn using main block and lip line.” and up to you [inaudible] likely not so… there are going to be a number of hurdles to get over and this is really, if you have an opinion about it  drop me an e-mail and if you would like to get in on, not so much discussions but I can put you in to contact with some of the committee members who are in those discussions. Drop me an e-mail mike@iti.com and I will, at least, put you in touch with some of the folks that are on subcommittee for making that decision and they might be able to kind of keep you up to paste, that’s where do we stand now, do you have a strong opinion about it or against and might even, a certainly this [inaudible] welcome to the point 5 subcommittee. So if you have an opinion lets share and bring it forward and we would love to hear what you have to say about… I think it’s also important to hear what the industry experts, because there’s probably 15 members on a subcommittee and another 40 plus members on the main comity and they all want safety as the first element. But there are provisions that would allow for that, can we do it safely and will be the big question and with those subject matter experts and industry folks, if it could be determined and by the manufacturers who also sit on a subcommittees and main committees, if it could be done reasonable, you know, well safely they will likely promote that as an allowable advance. So get a hold of me, mike@iti.com, and let me know if you would like to get in touch with some of those folks, and I will certainly hand you over to them and you can have those discussions, they appreciate it very much. Ok Zack last question.

 

Zack: Yeah, last question from Anthony Muñoz from [inaudible] we appreciate the questions guys. Do you have any practice that you would follow [inaudible] percentage of working limit you use on rigging hardware? Another word is it acceptable to use 100% of the working level limits if it is in good working condition?

 

Mike: Absolutely, yeah, we have always been, we have always been a believer in a making sure that we have full capacity and so I will just bring the hardware up here if… So when we know we have got, let’s say 7 and a half tone for a one inch shekel or a 8 and a half tons for one inch shekel or 12 tons for an inch and a quarter it does have a design facto, 5 to 1 or 4 to1, 5 to1, 6 to 1, in those ranges and if I need a 12 ton shekel for a 12 ton connection I have no problem rigging right to that number. If I know, here’s the other side of that, if I know I have got 12.2 tons load or tension versus 12 tone shekel I am immediately in violation for both OSHA and ASME. So it’s what can I justify, what can I defend? And if I am at my tonnage capacity with that shekel I am good to go. The reason that design factor off course is for wear, [inaudible] loss, wear and use that cause some loss across cross section and shock load. And those are the two big reasons that we have design factors in almost all of our rigging, to allow force some small amount of wear before we have to take out for service, not deformation and to, because we know the loads end up with some dynamic loading, it might be 1.1, 1.2, 1.6, times actual payload but we will end up with some shock loads just from normal natural hoisting and lowering. So we know we have to have those design factors in place. But that design factor is there to help absorb for that normal load handling activity, it’s OK to do that, I mean that’s fine, and we don’t preach that you need to be one ton above or two tons above or 10% above or 15%, we don’t preach that and nor does anybody impose that from an OSHA, ASME stand point. Rigging right to the capacity, right to the [inaudible] load weight with the right tonnage capacity shekels is perfectly fine, that also holds true for the rigging, for the sling. One thing, as you start adding rigging you start adding weight and you are going to have to count for that or compensate for that. But it’s OK to rig to the known capacity if we are within its rated capacity, that’s all it says. The main big word that OSHA uses is, and ASME, not to excide and that’s always the big [inaudible] and so once we have got that in mind and we can say: “Yes we maintained in the capacity of that rigging and we are good to go.” Even thou we don’t know we are going to have some dynamic loading. That’s part of, if you are doing demolition work I think it’s prudent on us to ramp up our rigging sizes because we are going to get really drastic dynamic loading. And that’s when we up size the rigging but normal lifting, normal operating speeds up and down, the rigging should easily be able to handle it and not walk away with any deformation as a result of standard load handling. Great question, I do appreciate it. Ok Zack, we do appreciate everybody’s participation and have enjoyed today and I do appreciate the questions very much and we have really enjoyed the time with you. We have got a great number of folks that started with this, have finished with this even thou we have gone to quite a distance here for ours program presentation. You will be getting the additional announcements about future webinars that we will do with variety of subjects, from our organization we sure appreciate you sharing those with others and participating with us again in the future. Zack I am going to give you the last word and thanks very much for allowing me to participate today.

 

Zack: Alright, alright, thank you and thank everybody again. You will be getting an e-mail of how to access the presentation after, I think about an hour after this thing closes and then you will be also able to download [inaudible] and also view the recording or send it to folks that have missed it. So enjoy your day, enjoy your weekend and thanks for attending we will talk to you soon, thank you.
