Frequently Asked Questions
Are the elevator wire ropes durable?
Our elevator wire ropes meet special provisions and requirements. The configuration considers not only wire rope and rated load, but also traction size, resulting in tensile strength greater than the lift weight. The safety factor includes at least four wire ropes to prevent simultaneous breakage.
Is it dangerous if power fails suddenly during elevator operation?
The elevator will automatically stop using electrical and mechanical safety devices. In case of power failure, elevator brakes engage automatically. Power supply departments typically provide advance notice for planned outages.
Will users be hurt if the door closes suddenly?
The door automatically restarts if touched during closing, with no danger. Anti-pinch switches prevent closure when obstruction is detected, and closing force is carefully regulated.
How does the elevator operate?
Elevators operate via counterweight wire ropes through traction drive, moving vertically on guide rails.
Is escalator installation complicated?
Our escalators feature integrated structures for precision and efficiency, designed for easier installation and commissioning.
Do you have any certifications?
Yes, we hold ISO9001, CCC, and CE Certificates for our products.
