37×7 Steel Wire Ropes for Spin & Rotation Resistance

Rotation resistant wire rope refers to a series of steel ropes which minimizes the tendency to spin or rotation under load. These wire ropes boast special design – the outer layer is twisted in the reverse direction of inner layers for counteracting torsional forces generated from multi-layers of strands.

To achieve the resistance against the spin and rotation, all wire ropes are composed of at least two layers of strands. In general, more layers a rotation resistant wire rope has, more resistance it will boast. For example, 2-layer ropes is much easier to spin and rotate than 3-layer ones. Meanwhile, if one end of free rotation is allowed, 2-layer rope can only develop 55% to 75% of its breaking strength comparing with 95% to 100% of 3-layer ropes.

According to characteristics of rotation resistant wire ropes, three categories are supplied by our company to suit your different needs:

Normally, 2-layer spin and rotation resistant wire ropes can meet your needs of low and medium rotation resistance.

The 3-layer rope with more outer strands is capable to distribute more 

radial pressure onto inner layers and ideal for larger mobile such as all tower cranes.
