A or a plurality of strands of fine steel wire twisted into a flexible rope, wire ropeis composed of several layers of steel wires are twisted into stocks, again with the rope core as the center, a certain number of strand wound into a spiralrope. In material handling machinery, used for lifting, traction, pulling andcarrying with. Steel wire rope has high strength, light weight, stable work, not easy to suddenly the whole root fracture, reliable work.

Steel wire

Steel wire rope to bear the load, its performance is mainly composed of a steel wire decision. Steel is carbon steel or alloy steel by cold drawing or cold rolledinto round (or special) wire, with very high strength and toughness, and according to the use of different environmental conditions on the steel wiresurface treatment.

Rope core

The main effect of rope core is to increase the elasticity and toughness ofsteel wire rope, steel wire, reduce friction and lubrication, improve the service life of wire rope. Commonly used rope core types include organic fiber (such as hemp, cotton), synthetic fiber, asbestos core (high temperature) or softmetal materials.

Classification

Edit

The steel wire rope according to the shape, level, classification of state etc..

Shape

The 1 round strand wire rope

2 braided wire rope

3 flat wire rope

State

The wire rope can also according to shares in the contact state between each layer of steel wire is divided into point contact, line contact or surface contact3.

Wire rope point contact: shares in wire diameter are the same. In order to make the steel stress is uniform, each layer of steel wire twisted around the rear spiral angle of approximately the same size, but the torque range, so the inner layer and the outer layer steel wire cross, in point contact state.

The line contact wire rope: each layer of steel wire strands of screw distance is equal, the inner layer and the outer layer steel wire in contact with each otherin a spiral line, a line contact state. Performance of linear contact lay wire ropes than point contact are greatly improved, so widely used.

The surface contact wire rope: a facial contact strands, the outer layer made of profiled steel wire with smooth surface, good wear resistance, compared with other types of wire rope of the same diameter, tensile strength is big, and can withstand the lateral pressure, but the flexibility is poor, complex process,high cost, often used as a carrying cable. Such as cable of cable crane andthe aerial ropeway.
