WFT-1 safety device control elevator compensation chain
Product feature
WFT series of elevator balance compensation chain, break through
the traditional elevator balance chain of a single balance
compensation, the introduction of a new function - the role of
security measurement and control.WFT-1 safety control device of
elevator compensating chain,
product structure by the high quality welding cable, rubber
composite and safety detecting and controlling device, the perfect
combination, forming its unique function. Product advantages not
only has good elasticity, difficult to burn, aging resistance, cold
resistance, excellent performance, and stable performance is good,
low noise characteristics and into a a brand characteristics,
safety monitoring, elevator operation, safety is the eternal theme,
we will lift safety monitoring work can magnify, in operation such
as encountered in emergency situations, safety monitoring will pass
the first time signal to the control system, parallel to control
security system, so that the lift to take
emergency measures, thereby reducing the risk of safety, avoid the
occurrence of safety accidents.Suitable for 1.75M/S above the
middle and high speed elevator.

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.
