Safety Device Control Elevator Lift Compensation Chain

Product Description

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.
