Core technical advantages: First, high-strength composite steel belt, adopting "steel wire + polyurethane" composite structure, breaking strength is 1.5 times that of traditional steel wire rope, flexibility increased by 50%, no broken wire, no rust, maintenance-free, service life up to 30 years, twice that of steel wire rope; Second, lightweight high-efficiency transmission, traction wheel diameter reduced by 40%, weight reduced by 50%, transmission efficiency increased to 98%, reduce traction machine load, elevator energy consumption reduced by 35%, annual power saving of single elevator up to 3000 degrees; Third, low noise and low vibration, flexible meshing between steel belt and traction wheel, no abnormal noise of steel wire rope friction, operating noise reduced by 20% (≤50dB), vibration amplitude reduced by 60%, ride comfort greatly improved; Fourth, upgraded safety redundancy, steel belt built with multiple independent steel wires, single wire break does not affect operation, equipped with steel belt wear monitoring and fracture warning system, safety redundancy far exceeds steel wire rope; Fifth, convenient installation and maintenance, light weight and good flexibility of steel belt, installation efficiency increased by 60%, maintenance-free, maintenance cost reduced by 70%, adapt to machine-room-less and small shaft elevators, save building space.
