814 Heavy Equipment Safety

Do not attempt dual lifts unless absolutely necessary and only with competent supervision throughout the operation. Dual lifts are extremely dangerous. Shifting of the load can cause overloading and failure of one crane. This throws the entire load onto the second crane causing it to fail. Before making a dual lift, carefully determine the position for the cranes and the location of the slings to balance the load properly.

After repair or alteration of a crane or derrick involving its hoisting capacity or stability, its safe working load should be determined by a competent person. Have this person issue a written statement specifying the safe working load.

Test the brakes at the beginning of each new shift, after a rainstorm, or at any other time when brake linings may have become wet. When hoisting a capacity load, check the brakes by stopping the hoist a few inches above the ground and holding it with the brake.
Equip all cranes with an appropriate fire extinguisher. Keep the extinguishers maintained and ready for use.
