Metric Rotation Resistant
Metric Powerstrand Rotation Resistant Ropes are comprised of 19x7 Class wire ropes.
19x7 rope is a 2 layer rotation resistant wire rope with 12 outer strands. It is a general purpose rotation resistant wire rope suitable for main and auxiliary ropes on some mobile cranes, deck cranes, truck cranes and piling rigs. Use of swivels is not permitted.
Rotation Resistant Wire Ropes by design offer resistance to rotation, but are not considered a non-rotating rope. This design has a torque imbalance causing the core to be over stressed especially where the outer strands crossover the core. Therefore, repeated cycle lifting will cause wear on the inside core. A slip and cut program must be performed to prevent unexpected wire rope failure.
