Polyurethane Crane Buffer

The polyurethane crane buffer is a cushioning device molded from polyurethane microcellular elastomer, absorbing impact energy through its special microporous structure, acting like a spring with multi-chamber damping. Mounted at the ends of crane long-travel, trolley, or end carriages, it limits travel and cushions collisions to protect equipment and personnel, widely used on overhead cranes, gantry cranes, and elevators.

    Introduction

    The buffer absorbs energy through its microcellular structure; during impact it consumes 40% of the energy and stores 60% for later release, offering moderate rebound and good compressibility and resilience. Lightweight, easy to install, and maintenance-free, it produces no noise or sparks during cushioning, providing excellent explosion-proof performance, impact resistance, compression resistance, and corrosion resistance. Safe, reliable, and smooth, it is an ideal replacement for traditional rubber and spring buffers.

    Our Advantage

    Microcellular structure absorbs impact strongly with superior cushioning, protecting equipment and personnel.

    Quiet cushioning with no sparks and good explosion-proof performance, suitable for flammable and explosive areas.

    Lightweight and easy to install with no routine maintenance, reducing use and maintenance costs.

    Impact-resistant, pressure-resistant, corrosion-resistant, operating at -20℃~60℃ for harsh outdoor conditions.

    Consuming 40% and storing 60% of energy gives moderate rebound and smooth travel, preventing secondary impact.
