Professional Answer: A hydraulic cable pulling machine, also known as a hydraulic puller, is a heavy-duty piece of equipment used to pull power lines, conductors, or communication cables over long distances with precision and control. Unlike a simple mechanical winch, it uses a closed-loop hydraulic system to generate and manage pulling force. At Ningbo Changshi, our hydraulic pulling machines are engineered for two primary applications:

• Overhead transmission line (OHTL) Stringing: They are used to pull pilot ropes or conductors across towers and over terrain, often working in tandem with a OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioner to maintain a specific tension.

• underground cable laying: They are essential for pulling heavy, high-voltage cables through conduits and tunnels, where high friction and long distances make manual pulling impossible.
