Guidance of steel wire rope unwinding and installing
Unwinding a steel wire rope from the coil
When a rope is delivered from a coil, it shall be either unwound on a turntable or rolled out along the ground like a hoop. In the latter case ensure that the wire rope surface must keep clean; sand or grit that sticks to the lubricant might damage the wires when the rope travels over sheaves.
Unwinding the steel wire rope from the reel
An unreeling stand (turntable) should be used to unwind a wire rope from its reel. Another accepted unreeling method is to mount the reel on a shaft supported by two jacks or other structure.
Warning:
Under no circumstances must the rope be pulled off a coil while it is lying on the ground or looped over the head of the reel, because this procedure will inevitably induce one torsion per wrap into the rope.
Proper method of wire rope installing
If you are installing a right lay rope see under Fig.1 and Fig.2
If you are installing a left lay rope see under Fig.3 and Fig.4
For the non-rotated multi-layer rope，extra care must be taken. When installed, inspection shall be carried out to ensure that the drum, the wheel ,the fleet angles and the screw of the drum are suitable for the steel wire rope.
Make certain that the rope bends in the same direction when it is wound from the reel onto the drum, always from top to top or from bottom to bottom. If this procedure is not strictly followed, the rope will either try to twist between reel and drum or it will later try to regain its preferred position when in practical service. In both case structural changes of the rope may occur.
When cutting the non rotating multi-layer wire rope, mechanical or hydraulic cutter shall be used. Before cutting, both sides of the cut point must be properly seized by soft steel wire to prevent strands disturbance. After cutting, each end shall be welded.
