Installation of a New Wire Rope
The wire rope is given a natural bend or winding from the
coil. If the wire rope is on a reel, unwind the wire rope from
the reel or coil as shown in Figure 11-15. Use care to prevent
reverse bend in the wire rope.
1. Make sure that the equipment (drum, sheaves, etc.) are
in good condition.
2. Unwind enough rope from the reel to connect the wire
rope to the winch drum. Use care to prevent twists or
sharp bends.
3. Operate the winch slowly to move the wire rope directly
from the reel to the winch drum. Keep the wire rope
under tension and make sure the wire rope winds
correctly on the drum. Loose windings will increase wear
on the wire rope and cause bad performance.
4. After installation, operate the winch with a minimum load
until you see the wire rope is moving easily over the
sheaves and is winding correctly on the winch drum.
5. Gradually increase the speed and load until the wire
rope is moving at normal load and speed. This run-in
period adjusts the moving parts to each other.
