Anchor cable pullers are essential tools used in coal mines, tunnels, and other engineering projects for the dismantling and recovery of anchor cables.
Anchor cable pullers primarily use hydraulic or pneumatic methods to generate powerful thrust, pulling the anchor cable out of the anchorage. Their working principle is based on the transmission and conversion of force; through a specific mechanical structure, hydraulic or pneumatic energy is converted into mechanical energy to achieve anchor cable dismantling.
Hydraulic Drive: This is currently the mainstream drive solution. A hydraulic pump generates high-pressure oil, which drives a piston in a cylinder. The power is transmitted through high-pressure oil pipes to the pulling/tensioning structure at the actuator end, achieving tension control of the anchor cable. Dual-speed reversing pumps can also serve as a standalone power source for low-flow, high-pressure oil, adapting to different operational needs.
Electric Drive: An electric motor drives a mechanical transmission structure such as gears and chains to efficiently transmit power to the anchor cable working end. Some high-end models are equipped with electronic control systems for precise power output control, improving operational accuracy.
