Elevator Lift Safety Devices Rogressive Safety Gear With 10/16mm Guide Rails
Progressive safety gear represents the pinnacle of elevator overspeed protection systems, designed to engage during free-fall scenarios to halt elevator cars with controlled, life-preserving deceleration. Unlike instantaneous safety gears that apply abrupt stops, progressive models utilize wedge-and-rail friction physics to deliver variable braking force proportional to load and speed.
Core Technical Advantages:
Gradual deceleration profile (0.2-1.0g adjustable) prevents passenger injury versus traditional 2.5g+ impact stops
Auto-reset functionality allows post-inspection reuse without mechanical replacement
Dual-trigger system activates at 115-140% rated speed (EN 81-20/50 compliant)
Precision Engineering Elements:
Tungsten-carbide friction linings maintain consistent coefficient of friction (μ=0.4±0.05) across -30°C to 120°C
Load-sensing hydraulic dampers adjust braking force within 0.5 seconds for 300-3000kg car weights
Laser-calibrated guide rail engagement ensures full-surface contact within 5mm tolerance
Modern iterations feature:
Wireless condition monitoring of wedge wear (0.01mm resolution)
Predictive activation testing via integrated load cells
Corrosion-resistant aerospace alloys for coastal/high-humidity installations

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.
