KHG Series Hydraulic Buffer

KHG Series

When the moving object collides with the bumper head, the internal check valve is closed and the oil chamber is compressed. The compressed oil flows into the orifice bar through the multiple orifice hole and it absorbs the shock. In addition, as the piston rod enters the inside of oil chamber, the oil amount as much as the piston rod volume presses the chamber piston to compress thd gas chamber(performs the accumlator fumction), so that the pressure inside the gas chamber is increased, absorbs shock energy over the entire stroke ranges. When the shock absorption is completed, the compressed gas chamber is forced to the oil chamber area, and the check valve installed in the piston is opened to return the piston rod to its original position.

KHG buffer safely protect heavy machinery and equipment during transfer of heavy loads. The high-capcity buffer are individually designed to decelerate moving loads under various conditions in compliance with industry mandatory international standards such as OSHA, CMAA, AIST, DIN, FEM etc.
