Surface Contact Wire Rope Characteristics And Uses
Jun 12, 2018


Surface contact wire ropes have high wear resistance and fatigue resistance.

The surface of the steel wire rope is smooth, and the contact area between the steel wire rope, the sheave, and the steel wire rope is large in use, the contact stress is reduced, and the wear resistance is 2 times higher than that of the ordinary steel wire rope.

Due to the large contact area between the steel wires, the strands eliminate the tanning stress during the forming process. In the process of use, the bending stress is generated only when the steel wire bypasses the sheave, and the additional bending stress generated due to the existence of gaps in the partial steel wires is greater. Small, and there is no bending stress caused by the inter-layer wire pressing each other, the fatigue resistance of the surface contact wire rope is 1.7 to 2.8 times higher than that of the ordinary steel wire rope.


The surface contact wire rope has a large density coefficient, so that in the case of the same diameter and strength level, the total breaking tensile force (see wire rope inspection) is more than 25% higher than the ordinary steel wire rope.

Another feature of the surface contact wire rope is that it is not easy to use when used, has good pressure resistance and corrosion resistance, and can reduce rotation during use.

Surface contact wire ropes can replace most of the existing wire ropes and are used in the lifting of mine shafts and inclined shafts, wire rope tank roads, various hoisting hoists, electric shovels, tow ropes, mining machinery and aerial ropeways.
