Rail transit sliding door is a high-tech product independently developed by our company. It has beautiful and fashionable appearance, simple and reasonable structure, high reliability, large door opening, good sealing and high safety, and has good waterproof and cold proof effect.

● scope of use:

The sliding plug door device for rail transit is used to open and close the passenger door of tram, and can also be used for the passenger door of subway, high-speed railway, trolley bus and other products.

● main functions:

Centralized door opening and closing function of driver;

Single door fault removal function (isolation function);

Obstacle detection function;

Emergency unlocking function in the vehicle;

Door status LED indicator and audible prompt function;

Door fault diagnosis function;

Zero speed protection function;

The train is not in a static state and is not allowed to open the door.

● product advantages:

1. The electronic door controller with full digital control technology realizes the functions of door control, monitoring, diagnosis, self-learning and network communication;

2. Brushless DC motor drive, less electromagnetic interference, long service life and high reliability;

3. Full mechanical whole process locking mechanism is adopted, which is in the structure room, long service life and good maintainability.

4. Short mechanism design, and the mechanism length is less than |. Military and monthly workers have the characteristics of less free use, stable transportation and long service life;

5. Maintenance free special screw nut pair transmission, good environmental adaptability, long service life and high reliability;

6. Aluminum honeycomb composite structure door panel, light weight, high strength, good sound insulation and heat insulation performance;

7. After closing, the door leaf is flush with the external surface of the vehicle to improve the overall aesthetics of the vehicle.
