Spin-Resistant ＆ Nor-Rotating Ropes

A normal general purpose rope under tensile load has a tendency to rotate along its axis(core) in the direction of un-laying itself. By modifying the way how individual wires or strands are laid around their cores, ropes can be designed and produced with minimized self-rotating tendency. These specially designed ropes are called rotation-resistant ropes or non-rotating ropes. Examples of rotation resistant ropes are some spiral strand ropes such as locked-coil ropes; Concentric ropes; Multi-(strand)-layer ropes; and Single ropes ( Mono-track Ropes).

▼ Multi-Layer Rotation Resistant Rope

As suggested by its name, a multi-layer rope is produced by closing multi-layers of strands around its core (either steel strand core or fiber core). The excellent rotation resistance is obtained by laying each layer of strands in opposite direction around the core. Also, since the length of outer-most wires exposed to surface is relative short compared to round or spiral ropes, these wires do no protrude even when broken. With these qualities, Multi-layer rotation resistant ropes provide great advantages when used in dynamic applications, such as the hoist rope for cranes.

Main applications

As main hoist rope for cableways, cables, cranes

As auxiliary hoist rope for cranes and other mechanical hoist

As guy (supporting) line for crane booms, etc.

▼ Single Rope / Mono-Track Rope

As buildings being built higher and higher, a need for high performance ropes along with development of tower cranes have become evident. Becoming more and more popular are single ropes with virtually no bird caging and still satisfying requirement of single part threading. There are many constructions of single ropes specifically designed for its application. Single ropes are widely used as main hoist ropes for tower cranes, truck cranes, deck cranes, and floating cranes. Due to excellent rotation resistant and ease of handling, single ropes are also popular as lead lines when laying a long length of power cables. Also with a strong resistance against deformation, single ropes are used in deep-sea observation.

Main applications

Hoist rope for one part threaded cranes

Lead rope for power cable installation and logging cableway

With equipment vulnerable to rope’s bird-caging or to projection of core.

Others applications where high possibility of accident due to spinning of rope is evident
