Nylon coated wire rope needs to withstand alternating loads during its use, and its performance is mainly determined by the mechanical properties of the steel wire, the surface state of the steel wire and the structure of the steel wire rope. The material of the steel wire includes carbon steel or alloy steel. The steel wire rope is made by cold drawing or cold rolling. The cross section of the steel wire is round or special. Toughness, and appropriate surface treatment of the steel wire to meet the needs of different environmental conditions.

When the nylon coated wire rope is twisted, the steel wire that has been subjected to the drawing stress is subjected to the twisting stress. These stresses are mainly caused by the uneven deformation during the drawing of the steel wire and the twisting of the steel wire rope (strand). If the measures to relieve stress are taken, there will be large residual stress and elastic stress in the rope, which will reduce the technical function and working function of the wire rope to a large extent. , it will disintegrate.
That is to say, if it is on the twisting process of nylon coated wire rope. If the method of reducing the twisting stress (such as pre-deformation, post-deformation) is used, the nylon coated wire rope made has a lower internal stress, and then it will show non-disintegration. When the end is in a free state At the same time, the strands in the wire rope and the wires in the strands will not be scattered. This kind of wire rope is called non-slack nylon coated wire rope, which is not only to improve the fatigue performance of the wire rope, but also to use it in use. There are many advantages.
