TM 10-3950-672-10
Never operate the crane with less than two wraps of rope on the hoist drum.
Check the hoist brake by raising the load a few inches and holding it there. Be sure the hoist brake is working correctly
before continuing the lift. When using a controlled free-fall hoist, slowly return the hoist to normal lowering speed before
stopping the descent of a load. Quick stops could cause the machine to fail. Also refer to CONTROLLED FREE-FALL
HOIST information in this section.
Never pull sideways with the boom. Booms and swing systems are not designed to side pull and may be damaged if
subjected to excessive side loading. Booms are designed for lifting only freely suspended loads.
NEVER permit anyone to ride loads, slings, hooks, etc., for any reason.
Look before swinging your crane. Even though the original set-up may have been checked, situations do change.
Never stand or work on or near the superstructure while the crane is moving or swinging.
Keep everyone away from suspended loads. Allow no one to walk under a load. Ensure that all slings, ties, and hooks
are correctly placed and secured before raising or lowering the load.
Use tag lines, as appropriate, for positioning and restraining loads. Check the load slings before lifting.
Be sure everyone is clear of the crane and work area before making any lifts.
Check all braking and holding devices before operation. Perform an operational check of all braking (wheel and swing)
and safety holding devices before starting any crane or traveling operations.
Be sure the load is well secured and attached to the hook with rigging of proper size and in good condition.
Allow no one to ride on the crane, carrier deck, engine compartment, etc.
Tag line personnel must guide the load from the ground.
Use only slings or other rigging devices rated for the job and use them properly. Never wrap the hoist cable around a
load.
Check all tackle, hardware, and slings before use. Refuse to use faulty equipment.
Never work the crane when darkness, fog, or other visibility restrictions make such operations unsafe.
Exercise extreme caution when picking and carrying a load. Never pick and carry a load with a crane that is not
authorized for such operation.
