Center Opening Landing Door Device With DC110V / AC110V Voltage
The Elevator Center Opening Landing Door Device is a specialized mechanism designed for elevator systems where the
landing doors open from the center, providing a symmetrical and
space-efficient entry and exit point for passengers. This device is
a critical component of the elevator system, ensuring smooth,
reliable, and safe operation of the landing doors at each floor.
The center-opening design involves two door panels that slide
horizontally in opposite directions, meeting at the center when
closed and parting evenly when opened. This mechanism is
particularly advantageous in spaces where side-clearance is
limited, as it requires less lateral space compared to single-panel
sliding doors. The device is typically powered by a motorized
system, which may incorporate advanced technologies like Variable Voltage Variable Frequency (VVVF) control to regulate door speed, acceleration, and deceleration for
a quiet and seamless operation.
Safety is a paramount feature of the Center Opening Landing Door
Device. It is equipped with sensors, safety edges, and obstruction
detection systems to prevent the doors from closing if an object or
person is in the doorway. Additionally, the device is integrated
with the elevator's control system to ensure synchronization
between the car doors and landing doors, enhancing passenger safety
and system efficiency.
Durability and low maintenance are key characteristics of this
device, as it is designed to withstand frequent use in high-traffic
environments. Its robust construction and precise engineering make
it an essential component for modern elevator systems, ensuring
reliable performance and a positive user 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.
