ELEVATOR SPRING HALL DOOR SELF-CLOSING Door head hard spring side door soft tension spring 52CM

Function:
Balance the weight of the car
The elastic force of the spring is used to adjust the overall weight of the counterweight system so that it maintains a dynamic balance with the weight of the car (including the rated load), reducing the load on the traction machine and reducing energy consumption.
Principle: The spring can compensate for the weight deviation of the counterweight block caused by wear, installation error, etc., to ensure that the force on both sides of the traction wheel is balanced when the elevator is running.
Shock absorption and guidance
The counterweight device may vibrate due to the guide rail error during operation. The spring absorbs the vibration energy through elastic deformation, while assisting the guide shoe to maintain the stable guidance of the counterweight and reduce the operating noise.

The core role of springs in elevators
Safety assurance: buffering the impact of falling and preventing overspeed and loss of control, it is a key component of the elevator safety system.
Stable operation: balancing weight, reducing vibration and noise, improving riding comfort and equipment life.
Automation control: auxiliary door machines, weighing and other systems to achieve automatic reset and signal feedback to ensure the normal operation logic of the elevator.
Different types of springs are adapted to the working environment of high load and frequent start and stop of elevators through material selection (such as stainless steel, alloy spring steel) and structural design (such as spiral springs, disc springs), and are indispensable basic components in elevator mechanical systems.
