Time to Test Your Rigging Knowledge Again with an ITI Training Quiz

School may almost be out for the kids, but for those of us in the rigging and lifting industry, class is always in session! We have another chance for you and your team to test your rigging knowledge. This time we've got questions running the gamut from sling inspection criteria to coefficients of friction.

As always, if you find this quiz to be more difficult than you'd like, come train with us and brush up your skills! We've got upcoming training center courses as well as online course options via the ITI Learning Hub. Whatever your training needs, we can help!
