8x25 ROTATION RESISTANT WIRE ROPE

 

8X25

In a multi-part wire rope system where the blocks have a tendency to twist -- the 8 x 25 Resistwist rope has found successful application. It is a category 3 rotation resistant rope. The rotation-resistant characteristic is achieved by laying the eight outer strands around an independent wire rope core so these strands are in the opposite direction to the lay of the core. Thus, when the rope is in tension, opposing rotational forces are created between the core and the outer strands.

Though not as rotation-resistant, the 8 x 25 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.
