A polyurethane rubber bumper is a buffer installed on a hoist trolley or a crane to protect the trolley or crane in the event of a collision. Polyurethane buffer adopts low-frequency collision design and is spray-treated. It has excellent abrasion resistance, good cushioning effect and long service life.

Model JHQ-A bumper is for a hoist trolley, which is composed of bolts and polyurethane rubber bumper.

Model JHQ-B is for an overhead crane or gantry crane, which is designed with a buffer base pressure plate.

Model JHQ-C bumper is for an bridge crane or gantry crane, which is composed of flange base and polyurethane rubber bumper.

Features of Rubber Bumper:

The product has a large polyurethane density ratio, a small cushioning stroke, easy installation, and a significant noise reduction effect on noise generated during a collision. Polyurethane buffer adopts low-frequency collision design and is spray-treated. It has excellent abrasion resistance, good cushioning effect and long service life. The installation is simple, and the height and level can be adjusted according to the actual installation requirements.

It has a light weight and reasonable price. In use, iron and rubber collide with each other, which will produce less noise during collision, and will not make sparks. It is widely used in explosion-proof cranes and flammable and explosive mining, building materials, chemical and metallurgical industry.
