The Elevator Car Top Installation 2-Leafs Center Opening VVVF Door
Operator is a cutting-edge system designed for the precise and efficient
operation of center-opening, two-panel elevator doors. Installed on
the car top of the elevator, this operator utilizes Variable Voltage Variable Frequency (VVVF) technology to deliver smooth, quiet, and energy-efficient door
movement, making it an ideal solution for modern elevator systems
in commercial, residential, and industrial buildings.
The VVVF technology allows for precise control of the motor's speed
and torque, ensuring that the two door panels open and close in
perfect synchronization. This results in a seamless and reliable
operation, minimizing mechanical stress on the door components and
extending their lifespan. The center-opening design is particularly
advantageous for elevators with limited space, as it allows for a
wider entrance without requiring additional lateral clearance.
Safety is a key feature of this system, with built-in obstacle
detection and emergency stop functions. If an obstruction is
detected during door movement, the operator immediately halts or
reverses the door panels, preventing accidents and ensuring
passenger safety. The system also complies with international
safety standards, providing reliable performance in various
operating conditions.
The car top installation design simplifies maintenance and reduces
the need for frequent adjustments, as the operator is easily
accessible for inspections and repairs. Additionally, the
energy-efficient operation of the VVVF technology helps reduce
power consumption, contributing to sustainable building practices.
Overall, the Elevator Car Top Installation 2-Leafs Center Opening VVVF Door
Operator combines advanced technology, safety, and efficiency, making it a
reliable and high-performance solution for modern elevator door
systems.

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.
