There are two commonly used pre-tension methods of zinc aluminum alloy wire rope: online pre-tension of zinc aluminum alloy wire rope and offline pre-tension of zinc aluminum alloy wire rope.

The online pre-tension of zinc aluminum alloy wire rope is measured directly on the rope machine. The online pre-tension of zinc aluminum alloy wire rope is only applicable to the situation where the tension of zinc aluminum alloy wire rope is small, the tension range is small, and the effect is not very uniform. Under use;

The offline pre-tensioning of zinc aluminum alloy wire rope refers to the wide application range of zinc steel wire rope tension, which is convenient for the tension adjustment of zinc aluminum alloy wire rope, and the tension adjustment speed of the steel wire rope is fast; the adjustment method of other pre-tension is different.

The zinc aluminum alloy wire rope plays the role of bearing the load, and its performance is mainly determined by the steel wire. Steel wire is a round wire made of carbon steel or alloy steel through cold drawing or cold rolling. It has high strength and toughness, and the surface treatment of the steel wire is carried out according to different environmental conditions. Rope core: It is used to increase the elasticity and toughness of the wire rope, lubricate the steel wire, reduce friction, and increase the service life. Commonly used rope core organic fiber, synthetic fiber, asbestos core or soft metal and other materials.
