Ergonomically developed Crane Buffer has a key role in safeguarding material handling equipments like crane from impact. Notable for its heavy duty design, this product is also used as an important part of rail vehicles or trolleys to reduce mechanical stress. This buffer is designed with hollow piston rod, cylinder, choke system and floating separator piston. The buffer force is generated by displacement of its hydraulic oil via choke system. The displaced oil pushes its separator piston towards the upper part of the buffer in order to compress the nitrogen gas of the hollow piston. The low volume of its nitrogen gas helps to build up high gas pressure in it.
