Elevator Polyurethane Buffer – High-Capacity Shock Absorber, Durable Elastomer, OEM Sizes Available for Safe End-Stop Protection
The Elevator Polyurethane Buffer is a critical safety component designed for modern elevator systems. Engineered from high-grade polyurethane elastomer, this buffer provides reliable shock absorption during emergency stops or end‑travel overrun situations. Its advanced material composition delivers exceptional energy return, high load‑bearing capacity, and outstanding resistance to wear, oil, and temperature fluctuations—ensuring consistent performance over a long service life.
Unlike traditional spring or hydraulic buffers, the polyurethane buffer requires minimal maintenance, offers silent operation, and maintains stable damping characteristics under varying speeds and loads. It complies with international elevator safety standards (e.g., EN 81, GB/T 7588) and is available in multiple sizes and hardness grades to suit different elevator car weights and travel speeds. Easy to install and retrofit, this buffer enhances passenger safety while reducing downtime and replacement costs. Trusted by elevator manufacturers and maintenance professionals worldwide, the Elevator Polyurethane Buffer represents the optimal combination of durability, efficiency, and cost‑effectiveness for vertical transportation systems.
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.
