Non Rotating or Rotation Resistant Wire Rope

Rotation resistant wire rope is a special category (class) of wire rope designed to resist the tendency to spin or rotate under load. In general these ropes are used as single part lines, or in situations where operating conditions require a rope that will resist cabling in a multipart system. The essential nature of rotation resistant rope designs impose certain limitations on their application and necessitate special handling requirements not encountered with other rope constructions.

Rotation resistant wire rope is available in two general classifications:
1) Single layer-consisting of a single layer of three or four strands. Typically the strands support one another without a core member.
2) Multilayer strand (Multistrand)-consisting of two or more strand layers closed in opposing directions. Torsional forces generated by each layer of the rope counteract one another to minimize rotation.
