should yield the required line pull asa general rule of thumb?: 5%
6. All of the following are results of unbalanced reeving of the hook block EXCEPT::
Wear on the hook
7. Before a spreader bar or beams can be used they MUST have been:: Tested and approved
8. When materials are being hoisted to an upper level, a tag line is used to:: Help control the load

, service?: 5%
13. The methodical process that attempts to identify hazards and devise plans to
overcome or eliminate hazards which may interfere with crane or rigging is called:: Lift plan
