Elevator

A freight elevator with full computer control technology and AC VVVF drive,not only has superior energy-saving feature,precise leveling performance and high carrying capacity,but also has very high cost performance in the design with full consideration of interest demands if custormers.It can be widely used for vertical transportation in various occasions,such as factories,transportation centers,warehouses,and vehicles. Machine-room-less freight elevator is designed by use of advanced permanent magnet synchronous gearless traction technology,so the layout inside elevator hoistway is improved with no further deceleration device; the gearless traction machine-room-less freight elevator and reducing the failure rate NR freight elevator Variable frequency traction machine Variable frequency and asynchronous traction machine has the features, such as safety, energy saving,high efficiency, low noise, small vibration, smooth running, good lubricity, and superior performance, which greatly meets the high requirements of users for elevator products, including steadiness, energy saving and stable running. Control system With modular computer control technology, the control system is integrated with serial communication network, self-diagnostic system, intelligent selective collection system and group control dispatching system, enchancing the efficiency and reliability of the system overall, and meanwhile facilitating future upgrading and modernization of the elevator
