TM 10-3950-672-10
When performing pick and carry operations or operating on sloping ground, carry loads much less than the rated
capacity. Keep the load low, carry the load uphill from the crane, swing only to keep the load uphill, and always place the
loads on the high side.
When traveling with a load, the boom should be carried in line with the direction of motion.
Report any crane damage immediately.
Check all pin connections, bolts, latches, locks, braking and restraining devices, and operational aids before operation.
Perform a visual inspection and replace/tighten any damaged or loose devices prior to initiating any crane or traveling
operations.
Never leave the crane with a load suspended. Should it become necessary to leave the crane, lower the load to the
ground and stop the engine before leaving the cab.
Be alert-stay alert.
Long cantilever booms can create a tipping condition when in an extended and lowered position. Retract the boom
proportionally with reference to the capacity of the applicable load chart.
Never swing over personnel, regardless of whether load is suspended from or attached to the boom.
2-4. WIRE ROPE AND SHEAVES.
The following information is taken from a National Consensus Standard as referenced by Federal Government Agencies.
WARNING
Wire rope can become frayed or contain broken wires. Wear heavy leather-palmed work gloves when handling wire
rope. Frayed or broken wires can injure hands.
Never let moving wire rope slide through hands, even when wearing gloves. A broken wire could cut through glove and
cut hand.
All wire rope will eventually deteriorate to a point where it is no longer useable. Wire rope shall be taken out of service
when any of the following conditions exist:
1. In running ropes, six randomly distributed broken wires in one lay or three broken wires in one strand in one lay.
2. Wear of one-third the original diameter of outside individual wires. Kinking, crushing, bird caging, or any other
damage resulting in distortion of the rope structure.
3. Evidence of any heat damage from any cause.
