1. Fast repair speed, the head pulley can be replaced at time without disassembly on the site;
2. Use high elasticity, high wear-resisting rubber raw materials.
3. Wear-resisting layer adopts the special groove structure, increased coefficient of elevator belt and the head pulley, double the traction;
4. Significantly reduce the cost of maintenance and replacement frequency, reduce the labor intensity.
Cost: reduce replacement frequency and repair time, reduce the cost;
