3x19S 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, 3x19S wire ropes will not kink or form loops and hockles, as in conventional 6-strand wire ropes. 3x19S 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 3x19S 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 3x19S 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 3x19S 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
- Resists rotation
- Non-twisting
- Better and longer service life
- Higher strength to weight ratio
