Why Use Polyurethane Buffer for Bridge Crane

The polyurethane buffer utilizes the micro-porous bubble structure of the polyurethane material to absorb energy and buffer. During the impact process, it functions like a spring with multi-chamber damping.


This product is a relatively ideal buffering device. It is installed on various mechanical equipment that collide frequently, allowing the equipment to operate normally and reducing equipment and personnel accidents caused by collisions. For cranes, this buffer can be installed on crane traveling and trolley traveling frame with or without flange.


This polyurethane buffer is proved the best bumper for bridge crane and gantry cranes because the following reasons:

1. Energy absorption: Polyurethane buffers are designed to absorb the energy of impact and cushion the collision, which helps to reduce the damage caused to the crane and surrounding structures.

2. Durability: Polyurethane is a very durable material that can withstand frequent use and heavy loads, making it an ideal choice for bridge cranes that are constantly in operation.

3. Versatility: Polyurethane buffers can be customized to fit a variety of bridge crane configurations and requirements, making them a flexible and versatile option.

4. Noise reduction: Polyurethane buffers can help to reduce noise levels during crane operations, which can be particularly important in busy industrial environments where noise pollution is a concern.

5. Safety: By reducing the impact of collisions and minimizing the risk of damage to the crane and surrounding structures, polyurethane buffers can help to improve the safety of bridge crane operations and reduce the likelihood of accidents or injuries.
