Zigzag Corridor - Forward & Reverse in 7 Mins. [Video]

National Crane Operator Certification Exam Practice 

One of the required tasks of National Crane Operator Certification Exams requires the operator to display skills and ability by negotiating a "zigzag" corridor with a test weight on the hook. The task is timed and will reveal competency levels of the following operator attributes:

  • Avoidance of Unsafe Acts
  • Understanding of Crane Controls and Functions
  • Load Control
  • Travel Path Considerations
  • Understanding of Crane Hand Signals

The zigzag task starts when the test weight is lifted into the air, whilst maintaining contact with the ground with a 36 inch chain on the bottom of the test weight. The operator then must navigate the test load through a corridor made up of PVC poles, topped with balls. Points are deducted for the following:

  • Knocking a ball off a pole with the load
  • Moving the base of a pole off of a line on which it is centered
  • Knocking a pole over completely
  • The chain on the bottom of the test weight leaving the ground
  • Moving the load past poles with the chain off of the ground
  • Touching the ground with the load
  • Evading any portion of the corridor
  • Excessive time to move the test weight through the corridor

Okay, got it? Now see how its done!
