Wire Ropes Disentangling Wire Rope Parts
Proper Handling of Wire Ropes
If new wire rope is used with a long boom and the line parts are few in number, a coiling effect may be created, causing the rope to become tangled. This condition is dangerous because it will cause the hook block or load to rotate. Disentangle the rope as follows:
CAUTION Do not handle wire ropes with your bare hands. Always wear protective gloves when handling the wire ropes. Always handle wire ropes carefully and correctly. The life of wire ropes can be maximized if they are handled correctly. If handled improperly, wire ropes become deformed or lose their original strength, and must be replaced prematurely.
1. Let out the wire rope until only a few wraps of rope are left on the winch drum, and check the direction and number of twists.
2. Remove the rope socket from the boom or hook block, and eliminate the twists as described below. (1) If the rope is twisted in a clockwise direction, twist the rope further (i.e., turn it in the same direction as the twist). (2) If the rope is twisted in a counterclockwise direction, untwist the rope (i.e., turn it in the opposite direction of the twist). ◆If there are many twists, correct the rope in stages. Do not twist or untwist the rope more than four turns at a time.
How to Unwind Wire Rope Wire rope is wound in a coil or around a wooden spool when supplied. Unwind the wire rope by rolling the coil, or pull out the rope while rotating the spool. If the wire rope is unwound improperly, it may become twisted or have kinks, rendering it unusable. Even a slight added twist may cause the wire rope to become tangled.
(1) Rope twisted in a clockwise direction
(2) Rope twisted in a counterclockwise direction
