Torque Factor

Rotation

Rotation resistant ropes are manufactured with a steel core closed in the opposite direction to the outer strands. When under load the strands of the IWRC have a tendency to twist in one direction while the outer strands tend to rotate in the opposite direction. Rotation resistant ropes are used as hoist ropes for unguided loads. The lifting application can be a single fall or multiple fall reeving system. Non rotation resistant ropes are used as hoist ropes for guided loads with both ends of the rope fixed.

Main advantages of Special Wire Ropes are:

  • Good rotational stability over a wide load spectrum for torque balanced rotation resistant ropes.
  • Improved rope behaviour in multiple layer spooling on the drum for well balanced rotation resistant ropes made from compacted outer strands in langs lay execution and a solid steel core.
