TM 5-3810-307-10
Never swing or lower the boom into the carrier cab.
Stop the hook block from swinging when unhooking a load.
Swinging rapidly can cause the load to swing out and increase the load radius.
Swing the load slowly. Swing with caution and keep the load lines vertical.
Look before swinging your crane. Even though the original set-up may be been
checked, situations do change.
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.
Never swing over personnel, regardless of whether load is suspended from or
attached to the boom.
Be sure the load is well secured and attached to the hook with rigging of proper size
and in good condition.
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.
2-14.5
Hand Signals.
A qualified signal person shall be used at all times when;
working in the vicinity of power lines,
the crane operator cannot clearly see the load at all times,
moving the crane in an area or direction in which the operator cannot clearly
see the path of travel.
At all times use standardized hand signals previously agreed upon and completely
understood by the operator and signal person.
If communication with the signal person is lost, crane movement must be stopped
until communications are restored.
