Diameter of wire ropes

The method of measuring steel wire rope diameter is as below:

Twisting method and direction of wire rope

  • The twisting method refers to the spiral twisting direction of strand or wire in the rope.

  • Two types of twisting method: twisting in alternate directions and twisting in one direction.

  • Four types of twisting direction: right hand regular lay(RHRL), left hand regular lay(LHRL), right hand lang's way(RHLL), left hand lang's way(LHLL).

Twisting Method wire rope

Wire rope pitch

Wire rope pitch refers to the distance moved when one wire strand goes around the rope core for one round
