Unspooling anti-twisted steel wire rope
Before starting to unspool anti-twisted steel wire rope, you must always make sure that the reel is free to rotate during the operation. Any attempt to unspool a wire rope from a fixed reel may cause twisting or kinks.
The figures below illustrate the right ways and the wrong ways to unspool steel wire rope.
Always avoid sharp deflection angles between the reel and the first pulley. This could cause the wire rope to unstrand.This rule should be followed with all types of wire rope, whether they are anti-twisted or not.
Avoid unspooling the wire rope through small deflection pulleys and also avoid changing the level (vertical or horizontal).
If you need to unspool a heavy and large steel wire rope, use a brake to keep the wire rope under slight tension. NEVER allow the wire rope to slacken and form loops.
