Customization
Available
Sheave size, load capacity, and structure can be customized according to project requirements
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
