In certain instances, the use of rotation-resistant wire rope is necessary to provide rotational stability to the lifted load. In general, the use of these wire ropes is limited to those situations where it is impractical to:
- Use a tag line
- Relocate a rope’s dead end
- Increase sheave sizes
- Eliminate “odd-part” reeving
- Significantly reduce the rope loading and rope fall length.
Rotation resistant ropes have less of a tendency to unlay when loaded than do conventional wire ropes. This results in improved rotational stability to the lifted load. Rotation resistant wire ropes are designed in such a way that the rotational force of the outer strand is partially counteracted by the rotational force of the inner strands or core when the rope is subjected to a load.
