Elevator PU Polyurethane Buffer Lift Buffer For Elevator Safety Brake

Elevator Polyurethane Buffer: Advanced Energy Absorption for Safe Terminal Stopping

The elevator polyurethane buffer is a critical safety component designed to absorb kinetic energy and provide controlled deceleration when an elevator car or counterweight approaches its terminal landing. Engineered as an alternative to traditional oil or spring buffers, polyurethane buffers offer superior durability, maintenance-free operation, and consistent performance across diverse environmental conditions.

Key Features & Benefits:

• High Energy Absorption Efficiency – Compresses under load to dissipate impact forces, rated for speeds up to 2.5 m/s (EN 81-20 compliant).

• Long Service Life – Resistant to wear, UV exposure, and temperature fluctuations (-40°C to +80°C) without performance degradation.

• Maintenance-Free Design – Unlike hydraulic buffers, polyurethane models require no fluid replenishment or seals, reducing lifecycle costs.

• Compact & Lightweight – Up to 40% lighter than traditional buffers, optimizing pit space and installation flexibility.

Technical Specifications:

• Progressive Compression – Nonlinear deformation absorbs energy smoothly, preventing abrupt stops.

• Fire-Resistant Formulations – Self-extinguishing grades available for enhanced safety compliance.

• Corrosion Resistance – Ideal for humid or coastal environments where metal buffers may degrade.

Applications:

• Machine-Room-Less (MRL) Elevators – Space-saving solution for modern low-to-mid-rise buildings.

• High-Traffic Commercial Lifts – Withstands frequent impacts without fatigue.

• Regenerative Drive Systems – Compatible with energy-efficient elevator designs.

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.
