One Way Lift Governor Rope Tension Force 500~1600N For Gearless Traction Machine

One Way Lift Governor

The One Way Lift Governor is a specialized safety device designed to prevent elevator cars from overspeeding in a single direction (typically downward). It activates only when the elevator exceeds the preset speed limit during descent, providing directional speed control without interfering with normal upward movement.

Key Features & Operation

1. Unidirectional Activation: Engages only during downward overspeed, allowing unrestricted upward travel.

2. Mechanical Trigger: Uses centrifugal force or weighted mechanisms to detect excess speed, initiating braking or safety gear engagement.

3. Fail-Safe Design: Ensures activation even during power loss or system failure.

Applications

• Ideal for hydraulic elevators or systems where upward overspeed risk is minimal.

• Used in low-to-mid-rise buildings with limited travel height.

Advantages

• Simplified Design: Reduces complexity compared to bidirectional governors.

• Cost-Effective: Lower maintenance and installation costs for specific elevator types.

• Compliance: Meets regional safety standards (e.g., EN 81-2 for hydraulic elevators).

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.
