Frequently Asked Questions
1. Are the elevator wire ropes durable?
Yes. Configuration is not only for wire rope and rated load but also considers traction size. The tensile strength is greater than the weight of the lift, and the safety factor is equipped with more than four wire ropes to ensure they won't break simultaneously.
2. Is a sudden power failure dangerous during operation?
No. If a power failure occurs, the elevator will automatically stop due to electrical and mechanical safety devices. Elevator brakes are automatically applied in case of power loss.
3. Will passengers be hurt if doors close suddenly?
In the closing process, if someone touches the hall door, it will automatically restart. Anti-clamping switches and controlled closing forces ensure the door reopens upon contact.
4. How does the elevator run?
Elevators are operated with a counterweight wire rope through the traction drive (tractor), moving up and down along the guide rails.
5. Is escalator installation complicated?
We utilize an integrated structure for escalators, making the equipment more precise and efficient, which allows for easier and more convenient commissioning.
6. What certifications are available for these products?
The products are compliant with ISO9001, CCC, and CE certifications.
