Spin-Resistant Wire Rope
Rotation-resistant wire rope is specifically designed to prevent cable rotation while under a load. This is accomplished by laying the inner strands in the opposite direction as the outer strands. The rotational force of the two layers counteracts each other, reducing the chance of spin.
All of our rotation-resistant wire rope meets the dimensional and strength requirements of Federal Specification RR-W-410 (latest revision) and ASTM A1023
Rotation-Resistant Wire Rope Categories
The level of rotation resistance a wire rope provides is dependent upon both the number of strand layers and the number of outer strands and are broken down into categories.
There are three categories, and all of our spin-resistant wire rope falls into either category 2 or 3 due to their configurations. Neither category should be used with a swivel.
Category 2 Rotation-Resistant Wire Rope
When it comes to the number of outer strands, higher is better. The 19x19 and the 19x7 wire ropes both have more than 10 outer strands, and two layers of strands, meaning they can offer significant rotation resistance.
Category 3 Spin-Resistant Wire Rope
The 6x26 and 8x19 have 9 or fewer outer strands, so they can only be classified as spin-resistant.
