The basic knowledge of wire rope

Concept: wire rope, also known as cable, is made of high-quality steel wire shaft, twist strand, rope and other processes made of rope-like products, it has a light weight, high strength, good flexibility, to withstand the impact of strong, high-speed operation Noise, the use of security and other characteristics, widely used in tension fixed, transport traction, lifting and so on.

A round (or shaped) wire made of carbon or alloy steel by cold drawing or cold rolling. It is the basic unit of the constituent stock. In general, the greater the wire diameter, wear resistance and wear resistance, the stronger the wire diameter, the better the softness. The steel wire can be divided into circular and shaped shapes such as Z-shaped, V-shaped, H-shaped and so on. The surface can be divided into smooth (no coating), plating (coating), galvanized, Copper plating, plastic coating and other coatings). More common for the galvanized layer, which according to the coating can be divided into the first pull after the first plating and pull.

Steel wire rope surface is commonly divided into two kinds of smooth and galvanized, in a corrosive environment, and allows the full lubrication of the wire rope occasions, the general use of smooth steel wire rope. In the corrosive environment and not easy on the surface of steel wire coated grease occasions, should be used galvanized steel wire rope. The galvanized layer is firmly attached to the wire surface and provides cathodic protection. Corrosion-resistant long life Galvanized steel wire ropes are commonly used in marine and other rainy and humid environments.

A wire bundle formed by a certain number, one or more layers of wire.

The wire rope is covered with plastic and rubber.

Wire rope diameter refers to the wire rope size characteristics of the specified value.

The minimum breaking force of the wire rope can be calculated by the formula of the nominal tensile strength and the rope structure of the wire.

The thickness of the coating on the surface area of the steel wire is expressed in g / m2. The corresponding standard is specified.
