Key Advantages
- Lightweight Design: High-strength MC nylon sheave wheels significantly reduce overall unit weight while maintaining structural integrity and portability.
- Robust & Durable: Hot-dip galvanized steel frame combined with fully sealed ball bearings ensures reliable performance in harsh outdoor conditions—including high humidity and heavy dust exposure.
- Low-Resistance Operation: Heat-treated shafts paired with high-precision bearings guarantee long-term low-friction, smooth rotation.
- Flexible Installation: Supports both beam-mounted and shackle-suspended configurations, compatible with diverse tower types and construction scenarios.
- Multi-Cable Compatibility: Suitable for stringing conductors, OPGW optical ground wires, ADSS all-dielectric self-supporting optical cables, and communication cables.
Quality Assurance
Each sheave undergoes 100% rated load breaking force testing prior to shipment to ensure compliance with specified performance parameters.
