Steel Wire Ropes for Spin & Rotation Resistance

A rotation resistant steel wire rope is placed on the ground

Rotation resistant wire rope is composed of multi-layers of strands for minimizing the tendency to spin and rotation.

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:

Cross section of spin resistant steel wire rope

Spin resistant 2 layers & 8 to 10 outer strands

Cross section of rotation resistant steel wire rope

Rotation resistant 2 layers & 11 to 13 outer strands

Cross section of non-rotating-steel wire rope

Non-rotating 3 layers & 14 or more outer strands

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.

Application:
  • Serving as single part lines.
  • Whip hoist ropes.
  • Deck crane ropes.
  • Off shore crane ropes.
  • Pillar crane ropes, etc.
Detail:
  • Surface: bright or galvanized finish.
  • Lay style: regular or lang lay as your requirements.
  • Available with plastic impregnated.
  • Outer strands: 5 to 20 strands.

Note:

  • Wire ropes with 8 to 10 strands & 2-layer constructions without reversely twisted inner strands have very similar appearance to rotation resistant wire ropes, but they are not.
  • Rotation resistant wire ropes are considered to be less stable needing to be handled and installed with great care. They must be taken to avoid high loads with small diameter sheaves.
  • To avoid lay disturbances of the outer strands, it is recommended to ensure ends of the rope are seizes tightly, welded or brazed.
