| 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.
