Vvvf Passenger Elevator Door Operator , Center Opening Elevator
Door Components
The Elevator Door Operator is a vital mechanism within an elevator
system, responsible for the precise and safe operation of the
elevator car doors. It ensures the doors open and close smoothly at
each floor, facilitating passenger entry and exit while maintaining
safety and efficiency. The door operator typically consists of an
electric motor, drive system, and control unit, which work together
to manage door movement. It is equipped with sensors to detect
obstructions, ensuring the doors reverse direction if an object or
person is detected, preventing accidents. The system also
synchronizes with the elevator car control board to align door
operations with the car's position and movement. Modern door
operators are designed for quiet operation, energy efficiency, and
durability, capable of handling high-frequency use in busy
environments. Advanced models may include features like automatic
speed adjustment, diagnostics, and integration with smart building
systems. The Elevator Door Operator plays a crucial role in
ensuring passenger safety, accessibility, and a seamless vertical
transportation experience.

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.
