Cable Stringing Pulley Block

Core Advantages 

1. Cable-friendly nylon wheel

Made of tough wear-resistant nylon, it will not scratch wire insulation, aluminum strands or optical cable jackets during pulling, effectively preventing cable abrasion and cracking.

2. Anti-corrosion galvanized frame

The whole steel bracket adopts hot-dip galvanizing process to resist rust and rain erosion, suitable for long-term outdoor overhead operation with long service life.

3. Smooth pulling & stable load bearing

Built-in high-smooth bearing greatly reduces traction resistance for easy pulling. Thick steel plate and locking bolts provide high load capacity without shaking or cable jumping off the groove.

4. Two-way usage & easy installation

It can be suspended overhead via the top movable U-shackle or placed on the ground for linear stringing. No extra tools required for quick assembly, saving much time for high-altitude work.

5. Lightweight hollow wheel design

Hollow holes cut down overall weight to ease carrying and overhead hanging, while maintaining structural strength of the wheel.

6. Wide compatibility

Large wheel groove fits ACSR power wires, overhead ground wires, communication optical cables and low-voltage cables for universal application.

Main Applications

1. Overhead power line construction

Hang on utility pole and tower cross-arms to string ACSR conductors and overhead ground wires, protecting wires from sharp pole edges.

2. Communication optical cable laying

Used for overhead optical cable stringing on pole routes; the soft nylon wheel buffers and protects cable sheath to avoid fiber damage during pulling.

3. Cable pulling on construction sites

Lay flat on the ground in substations, factories and construction sites to guide cables and lower friction during traction.

4. Auxiliary tensioning & guying work

Serve as temporary guide pulley during power maintenance and line reconstruction, reducing traction loss when tightening wires and pulling guy cables.

5. Outdoor emergency power repair

Lightweight and portable for mountain and field repair sites; can be quickly mounted on various temporary hanging points for emergency construction.
