Tab/Accordion Items

What are the hazards associated with crawler locomotive and truck cranes?

Failure to use cranes within their specifications can cause the inadvertent release of a load, leading to employees being struck by or crushed by loads. Depending upon the size and weight of the load, this can result in serious injury or death.

What can I do to protect myself and others?

Do not walk or work under a suspended load and stay clear of the path of travel of a suspended load. If you are the operator, never allow your attention to be diverted while moving a load. Do not lift, lower, or transport a load with the crane or hoist until all personnel are clear of the load and the load’s path. Do not allow personnel to be lifted, lowered, or transported by means of the crane, hoist, trolley, hoist hook, or load.
