Wire ropes can be divided into single-wound rope, double-wound rope, and triple-wound rope according to the level of winding.

Single winding rope: It is made by twisting several thin steel wires around a metal core. It has poor flexibility and is easy to wear and break when repeatedly bent. It is mainly used as a non-moving tension cable. (One-time twist: the steel wire is directly twisted into a rope without strands)

Double-wound rope: The strands are twisted around the core of the rope to form a rope. The commonly used rope core is hemp core, and metalcore twisted with asbestos core or soft steel wire should be used for high-temperature operation. The rope core before rope making is dipped with lubricating oil, which can reduce the damage caused by the friction between the steel wires. The double-wound rope has better flexibility, simple to manufacture, and is the most widely used.

Three-wound rope: Double-wound rope is used as strands and then twisted around the double-wound rope core to form a rope, which has good flexibility; but the manufacturing is more complicated, and the steel wire is too thin and easy to wear, so it is rarely used.
