What is an elevator elevator overspeed governor tension device?
Elevator overspeed governor tension device is a crucial part in the elevator’s safety protection system. It is used to control the elevator’s operating speed and ensure passenger safety. The main function of the tension device is to maintain the tension of the overspeed governor’s steel wire rope, ensuring that the elevator does not experience safety accidents during operation caused by the steel rope becoming slack or breaking.
Elevator tension device mainly consists of the following components:
- Elevator Tension Wheel(Pulley)
- Elevator Tension Spring
- Elevator Guide Device
- Elevator Bracket
- Elevator Wire Rope Brake Tension switch
- Heavy Weight Black
Types Of Elevator Tension Device:
- Swing Arm Type Elevator Tension Device
- Weight Load Type Elevator Tension Device
To compensate for the elongation of the elevator overspeed governor rope during operation, the tension device floats up and down within the guide device. To prevent failure due to rope breakage or excessive elongation, the tension device must have an appropriate height from the bottom of the pit.
- For low-speed elevators: 400 ± 50mm
- For fast elevators: 550 ± 50mm
- For high-speed elevators: 750 ± 50mm
As the side of the tension device is equipped with a rope break protection switch, if the overspeed governor rope breaks or over-elongates, the tension device falls, triggering the rope break protection switch, which cuts off the elevator control circuit to prevent the elevator from operating without the protection of the governor and safety gear.
Therefore, choosing a high-quality elevator oeverspeed governor tension device is crucial for ensuring the safe operation of the elevator. When selecting such a product, attention should be paid to its materials, design, and manufacturing process to ensure it meets the safety requirements of elevator operation, providing passengers with a safe and comfortable riding experience.
