0.25m/s Elevator Progressive Safety Gear For Elevator Safety Devices
Elevator safety gear is a critical component designed to prevent catastrophic accidents by stopping an elevator car in the event of overspeeding or free-fall. Installed on the car frame, it engages with the guide rails when triggered, halting uncontrolled movement.
There are two main types: instantaneous and gradual. Instantaneous safety gear activates abruptly, clamping the rails with high force, suitable for low-speed elevators. Gradual safety gear applies progressive braking, minimizing jerk, and is used in high-speed systems.
Modern safety gear operates via a speed governor system. If the car exceeds a set speed, the governor rope triggers the safety mechanism, activating wedges or rollers to grip the rails. Redundant sensors and electronic controls enhance reliability.

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.
