Product Advantages
- Flexible Performance: Multi-thin steel wire structure provides excellent bending performance, suitable for frequent bending and winding scenarios including elevator traction ropes, auxiliary hook ropes for lifting machinery, and small winch ropes
- Wear and Compression Resistance: Large number of steel wires disperses stress surface, effectively resisting compression wear and prolonging service life during repeated operation with pulleys and drums
- Strength Balance: Moderate overall breaking force balances strength and flexibility, offering cost-effective performance in industrial applications
- Common Specifications: Diameter range from 3mm to 12mm allows flexible selection according to load requirements
