Elevator Shaft Magnetic Brake System – High-Safety Emergency Stop
Solution
Elevator shaft magnetic absolute value information system
Applications
This product is used for absolute position detection of elevator
cabins, achieving leveling without the need to encode floors or
record floor numbers. The detection accuracy is higher, and the
installation in the elevator shaft is not affected by environmental
factors, making it simple to install and highly efficient.

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.
