CABLE, BOOM, AND LEVEL WIND

Always wear leather gloves when handling winch cable. Never allow cable to

run through hands. Broken wires can cause painful injuries. Do not operate

winch/crane with less than four turns of wire ropes on drums. Failure to observe

these warnings could result in injuries to personnel.

During winch/crane operations direct all personnel to stay clear of operations

area. A snapped cable or shifting load can be extremely dangerous. If faulty

equipment halts operation, notify unit maintenance personnel immediately.

Arrange signals with equipment operator per FM 21-60 to prevent injury to per-

sonnel or damage to equipment during loading/unloading operations.

Equipment operators will not allow personnel to stand or walk under lifted load.

Any kinks, crushed sections, or broken strands are potential weak points and

can cause wire rope failure. Frayed, kinked, worn, or corroded ropes must be

replaced. Rope is unsafe if 3 broken wires are found in one strand of 6 x 7

rope, 6 broken wires in one strand of 6 x 19 rope, or 9 broken wires in one

strand of 6 x 37 rope.

Do not touch level wind slide assembly unless the level wind switch is in OFF

position. Unexpected turning of cab and boom may injure personnel and damage

equipment.

Make sure all personnel stand clear of any suspended load when releasing boom

winch brake.

Make sure all personnel stand clear of boom.

Make sure all personnel stand clear of any load supported by the wire rope

which may roll free when releasing tow winch brake.
