Pullers & Machines
Puller 50kN
The hydraulic puller is designed for controlled overhead stringing of conductors, ground wire and OPGW, providing a constant pulling force of up to 50 kN over long distances.
Unlike a winch, the pulling rope passes through the capstan system and is not stored, ensuring uniform tension, precise speed control and maximum conductor protection.
The machine is optimized for continuous-duty stringing operations, where stable pulling force and smooth operation are critical.
It is typically used in combination with external rope reels or reel stands, allowing virtually unlimited pulling length.
