Torque-Balanced

Torque-Balanced wire rope resists rotation. At loads approaching the elastic limit—75% of rope breaking load—tests show rotation to be less than 1° per foot of rope length. Even when there is a sudden release of load, Torque-Balanced wire ropes will not kink or form loops and hockles, as in conventional 6-strand wire ropes. Torque-Balanced wire rope will give you better and longer service life free of the problems associated with conventional wire ropes in undersea operations.

The elastic limit of Torque-Balanced wire rope is 75% of normal rope breaking load, compared to approximately 50% for 6-strand ropes. The importance is that the payload of a Torque-Balanced wire rope, at the elastic limit, is 50% greater than that of an equal strength 6-strand rope with no difference in diameter.  Additionally, since a Torque-Balanced wire rope weighs less (about 10%) than a conventional 6-strand rope of the same size and strength, it has a much higher strength to weight ratio.  Specify:  Bright, Galvanized, or Jacketed wire rope.
