1.0m/S Machine Roomless Passenger Elevator Lift With Vvvf Drive
Traction elevators
Machine room less elevators do not have a fixed machine room on the top of the hoistway, instead the traction hoisting machine is installed either on the top side wall of the hoistway or on the bottom of the hoistway. The motor is installed using a permanent magnet which "sticks" the motor permanently and work with Variable Voltage Variable Frequency (VVVF) drive. Some of the hoisting machines are using gearless synchronous motors instead conventional induction motors. This design eliminates the need of a fixed machine room and thus saves much building's space. Almost all the traction MRL elevators are gearless traction.

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.
