700kg Elevator / Lift Gearless Traction Machine Motor For Elevator Parts

Sheave Φ 480mm Elevator Lift Gearless Traction Machine (SN-B2500)

A lift gearless traction machine is a high-performance drive system used in modern elevators, particularly in high-rise and ultra-high-speed applications. Unlike geared traction machines that rely on a gearbox to reduce speed and increase torque, gearless systems eliminate mechanical gears, resulting in smoother operation, higher efficiency, and reduced maintenance. These machines are commonly found in skyscrapers, commercial buildings, and premium residential elevators where speed, reliability, and energy efficiency are critical.

FAQ
1. Are the elevator wire ropes durable?
The elevator wire rope has special provisions and requirements. Configuration is not only for wire rope and rated load, but also considered the size of the traction, as a result, the tensile strength of wire rope is greater than the weight of the lift. The safety factor is equipped with more than four wire rope. So it won’t break at the same time.
2. Is it dangerous for power failure suddenly during the elevator running?
If it occurs, the elevator will automatically stop due to the electrical and mechanical safety device. In case of power failure,elevator brakes will automatically taken. In addition, the power supply departments such as planned outage, prior notice are also operating.
3. Will us be hurt when it closed suddenly?
In the closing process, if people touch the hall door, the door of elevator will automatically restart without any danger. With anti clamping switch, once the gate touched, this switching action make the elevator unable to be closed and even reopened. In addition, closing force is also available here.
4. How the elevator running?
Elevators are operated with a counterweight wire rope through the (tractor) traction drive, making ups and downs on the guide rail.
5. Is the escalator installation complicated?
We believe the functions of an escalator are not necessarily proportional to the operation complexity. Therefore, escalators designed by us apply an integrated structure, so that the equipment is more precise and more efficient and allows easier and more convenient commissioning.
6. Do you have any cerifications?
Yes, we do with ISO9001 / CCC / CE Certificates for u.
