One end of the steel wire rope of the rotary drilling rig is fixed to the winch drum, passes through a fixed pulley and a guide pulley, and the other end is connected to the hoist at the top of the drill rod. Because it does not use a movable pulley design, the steel wire rope must have a high single-rope tension to ensure that the hoist rotates freely under counter-torque and to ensure the safety and reliability of the drill rod lifting process. The ope is mainly used to lift the drill rod and drilling tools. Frequent up-and-down movements during rotary drilling place high demands on the wear resistance of the wire rope, directly affecting its service life.

The telescopic boom of a rotary drilling rig uses steel wire rope, which is pulled by a hydraulic cylinder to extend and retract the boom like a telescope. The core components are the wire rope and pulley system. One end of the rope is fixed to the boom, passes over a pulley, and connects to the lower boom section. When the hydraulic cylinder extends or retracts, it pulls the wire rope, causing the lower boom section to extend and retract synchronously. Note that not all rotary drilling rigs have a telescopic boom.
