with complete solution
What should be given a visual inspection prior to use?
All rigging equipment slings and hardware
What do you do with defective components?
Destroy defective components
What is the most important precaution in hoisting and rigging?
The most important precaution is to determine the weight of the load before attempting
to lift it
What is the SWL and when is it determined?
Safe Working Load of all equipment, slings and hardware and once the weight of the
load in known.
What is necessary before any crane lift?
A lift plan
What is a lift plan?
This identifies the requirements needed for the primary areas of every lift.
What are the requirements included in a lift plan?
It identifies the size shape and weight of the load, where it will be lifted from, where it
will be placed and the placement of the cranes.
