Product Description

Progressive Elevation Safety Gear – Reliable Overspeed Protection for Elevators

Overview
The Progressive Elevation Safety Gear is a critical safety component designed to protect elevator passengers by preventing uncontrolled descent in case of overspeed. Installed on the elevator car, it operates smoothly during normal conditions but instantly engages when excessive speed is detected, clamping onto the guide rails with precision-engineered friction to bring the elevator to a controlled stop.

Engineered for reliability and compliance with international safety standards, our safety gear ensures maximum protection for both passengers and elevator systems.

 
Key Features

Automatic Overspeed Activation – Triggers only when necessary, ensuring smooth operation under normal conditions.

High Friction Clamping – Secures the elevator car onto guide rails, preventing free-fall accidents.

Durable & Low Maintenance – Built for long-term reliability with minimal servicing requirements.

Wide Compatibility – Suitable for various elevator speeds and load capacities.

Certified Safety Compliance – Meets GB standards for elevator safety components.

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.
