  Cable Feeders

  Cable Feeders Equipment are used to push cables forward during installation in trenches, ducts, or tunnels. Working with Cable Pulling Winches, they help reduce pulling tension, prevent cable damage, and support long-distance cable laying. Changyun Technology Cable Feeders use rubber crawler belts to clamp and push the cable, delivering strong traction without damaging the cable. They also support linked multi-unit synchronized control and constant-speed operation, ensuring safe and efficient long-distance cable laying.

  Fiber Optic Cable Pullers

  Fiber Optic Cable Pullers are specialized machines designed for fiber optic cable installation in ducts, cable trays, trenches, and other communication network projects. They pull fiber optic cables smoothly from the cable drum and guide them safely to the installation point. Changyun Technology's Fiber Optic Cable Pullers support long-distance pulling operations of more than 1,500 meters. The upper-and-lower rubber track clamping system with automatic tensioning ensures reliable non-slip traction while preventing cable slippage, crushing, twisting, and displacement during installation.

  Cable Pulling Winches

  Cable Pulling Winches (Cable Winches ) are pulling and lifting machine used for cable laying, pulling, and cable recovery in power, communication, and marine engineering projects. They use drums to wind and release pulling ropes or steel wire ropes, working with cable mesh socks to connect and pull cables. Widely used in overhead transmission line stringing, transmission tower erection, underground cable installation, and long-distance large-section cable laying, they often work with Cable Pushers for coordinated multi-machine operation. They feature extra-high pulling force, diesel or gasoline-powered models for off-grid operation, remote-control operation, and stepless speed regulation.

Overhead Line Stringing Equipment

• 

  Hydraulic Pullers

  Hydraulic Pullers are core pulling equipment for overhead transmission line stringing. Powered by a hydraulic drive system, they provide strong and smooth pulling force and work together with hydraulic tensioners to pull conductors, ground wires, and OPGW through stringing blocks along transmission towers. With stepless speed control and stable tension regulation, they help ensure safe, efficient conductor stringing and are widely used in UHV lines, long-span crossings, and complex terrain.

  Hydraulic Tensioners

  Hydraulic Tensioners are core equipment for overhead transmission line stringing. They provide adjustable and constant back tension to conductors and work with Hydraulic Pullers to maintain proper tension and clearance during stringing. With precise pay-out control and responsive braking, they help prevent conductor abrasion, twisting, and damage, making them ideal for UHV lines, long-span crossings, and complex terrain.

  Hydraulic Puller-Tensioners

  Hydraulic Puller-Tensioners combine pulling and tensioning functions in one machine for high-voltage and ultra-high-voltage overhead transmission line stringing. They can operate as either a Hydraulic Puller or Hydraulic Tensioner, providing strong pulling force for conductor stringing and constant back tension for controlled pay-out. They help reduce equipment and transport costs while improving jobsite mobility, making them ideal for emergency repair, sectional stringing, long-span crossings, and complex terrain.
