Elevator door hanging plate

The elevator door hanging plate is the core component of the elevator door suspension device, and its specific function can be analyzed from the following perspectives:
1. Support and suspension functions
The door hanging plate is fixed to the elevator door frame by bolts or welding, directly bearing the weight of the elevator door, and is the main load-bearing component of the door leaf.
It cooperates with the hanging wheel to enable the door leaf to slide along the door guide rail, achieving smooth opening and closing actions.
2. Guidance and stability guarantee
The door hanging plate is in contact with the door guide rail through the hanging wheel at the bottom, ensuring that the door leaf maintains linear motion during operation, avoiding deviation or jamming.
During the process of opening and closing doors, the door hanging plate needs to withstand dynamic impact forces (such as inertial forces when the door leaf accelerates or decelerates), and its structural strength directly affects the safety of the elevator door.
3. Key points of maintenance and fault prevention
Regularly checking whether the fixing bolts of the door hanging plate are loose can prevent the door leaf from falling or operating abnormally due to component detachment.
If the wear of the hanging wheel causes the door leaf to fall, the door hanging plate needs to be replaced with a new hanging wheel to restore the balance position of the door leaf.
The elevator door hanging plate is the central component connecting the door leaf and the driving mechanism. Its design needs to consider strength, wear resistance, and maintainability to ensure the long-term reliable operation of the elevator door system.
