Heavy duty shock absorber

HI Series

Product introduction

HI Series

The HI series of shock absorber is specially for the safety of heavy-duty mechanical equipment. They are air-liquid separated and are returned with nitrogen. This design facilitates maintenance. At the same time, the HI series also features large bore and high absorption energy to protect the safety of heavy machinery.It is used in port, railway, steel and other industries. Its characteristics are cylinder bore drilling and high energy absorption. It can effectively reduce the moving load of heavy-duty machinery and equipment.Its working principle is that when the impact head is impacted by external force, the piston rod moves downward and compresses the hydraulic oil to pass through the orifice to produce damping force. At the same time, the hydraulic oil squeezes the nitrogen in the air chamber. When the load is removed, the high-pressure nitrogen will press the hydraulic oil to push the piston to move up to reset the piston rod and complete a working cycle.
