Product Description

Our 8 strand constructions are regular lay and either 19 Seale or 25 Filler or 26/36/41/ WS or 49 Seale/Filter Wires. The size relationship between strands and cores gives these ropes increased bendability over six-strand ropes of the same diameter.

  • Crush-resistant
  • Increased bendability
  • Fatigue-resistant

In a multi-part wire rope system where the blocks have a tendency to twist–the 8 x 31 Resistwist rope has found successful application. The spin-resistant characteristic is achieved by laying the eight outer strands around an independent wire rope core so these strands are in opposite directions to the lay of the core. Thus, when the rope is in tension, opposing rotational forces are created between the core and the other strands. Though not as rotation-resistant, the 8 x 31 Resistwist is more stable than a 19 x 7 rope. It also has increased resistance to bending fatigue and crushing. This is achieved through the use of eight-strand construction with an independent wire rope core.
