Center opening 4 panels landing door device(ZP interface)
The Elevator Center Opening 4 Panels Landing Door Device is an advanced and highly efficient system designed for the smooth and synchronized operation of center-opening, four-panel elevator landing doors. This configuration is commonly used in high-capacity elevators, such as those in commercial buildings, hospitals, and large residential complexes, where wider door openings are required to accommodate higher passenger traffic or larger loads, such as stretchers or trolleys.
The device operates by dividing the door into four panels—two on each side—that open and close simultaneously from the center. This design not only maximizes the available entrance width but also ensures efficient use of space in the elevator lobby. The system is equipped with precision-engineered mechanisms, including synchronized motors, rollers, and guides, to ensure that all four panels move in perfect harmony. This synchronization minimizes wear and tear, reduces noise, and enhances the overall durability of the door system.
Safety is a critical feature of the Center Opening 4 Panels Landing Door Device. It incorporates advanced sensors and obstacle detection technology to immediately halt or reverse door movement if an obstruction is detected, ensuring passenger safety and preventing damage to the door mechanism. Additionally, the system complies with international safety standards, providing reliable performance in emergency situations.
The device is also designed for ease of maintenance, with accessible components and a modular structure that simplifies inspections and repairs. Its energy-efficient operation further contributes to sustainable building practices by optimizing power consumption.
Overall, the Elevator Center Opening 4 Panels Landing Door Device combines innovative design, safety, and efficiency, making it an ideal solution for modern high-capacity elevator 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.
