Rotation Resistant Wire Rope
What is a Rotation Resistant Rope? Or a Non Rotating Wire Rope as it is also known.
In a conventional wire rope, an external load creates a torsional moment which tries to un-twist the rope. A rotation resistant steel wire rope has a steel core which is an independent rope, closed in the opposite direction to the outer strands. Under load, the core tries to twist the rope in one direction, the outer strands try to twist it in the opposite direction.
The geometrical design of a rotation resistant wire rope is such that the torsional moments in the core and the outer strands compensate each other over a wide load spectrum, so that even with great lifting heights practically no rope twist occurs.
These ropes are very common as hoist ropes on mobile crane.
