Product Description
7 Inch 178mm 20kN Single Sheave Universal Stringing Blocks with Low-Friction Cable Roller
Designed for overhead conductor guiding, cable pulling, and transmission line installation work. This versatile overhead pulley is suitable for power line construction, telecom cable installation, utility maintenance, and general cable stringing projects where stable cable guidance is required.
Common Installation Challenges
  • Cable surface damage during pulling operations
  • High friction between cable and support points
  • Unstable cable direction during overhead installation
  • Low working efficiency in narrow or complex job sites
  • Difficulty using one roller for different cable pulling angles
Technical Solution
This universal cable roller and stringing block addresses installation challenges through:
  • 178mm sheave diameter for smoother cable guidance
  • 20kN rated load for reliable field operation
  • Single sheave compact design for easy handling and quick positioning
  • Low-friction rotating pulley to reduce cable wear
  • Universal overhead pulley structure for different cable pulling directions
  • Heavy-duty frame construction for transmission line installation work

7 Inch Universal Cable Roller and Stringing Block - Industrial cable pulling equipment for transmission line installation
Operation Principle
The cable or conductor passes over the rotating sheave during pulling or stringing work. As the pulley rotates, it guides the cable forward and reduces direct friction between the cable and the support point. The smooth roller surface helps protect the cable jacket or conductor surface, while the strong frame keeps the pulling direction stable. This improves safety, reduces cable damage, and makes overhead line installation more efficient.
Applications
  • Transmission line installation
  • Power line construction
  • Overhead conductor stringing
  • Cable pulling projects
  • Utility maintenance work
  • Telecom and electrical cable installation
  • Temporary cable guiding on job sites
Selection Guidelines
  • Light and medium cable pulling: Choose 7 inch single sheave cable pulling blocks for compact and flexible operation
  • Overhead line work: Choose universal stringing blocks with stable frame construction and smooth roller rotation
  • Cable surface protection: Choose low-friction rollers to reduce abrasion during pulling
  • Different job site conditions: Choose universal overhead pulley design for easier positioning and wider application
  • Heavier pulling tension: Confirm the actual pulling force and select a rated load that is higher than the maximum working tension
