Hydraulic buffers absorb the kinetic energy of impacting objects by dissipating the energy internally. These are safely decelerated with no resultant damage to surrounding structures or to the moving object itself.

Most hydraulic buffers (shock absorbers) are sealed units and are maintenance free. These are designed to withstand multiple impacts and to operate on a continuous basis.

How This is Accomplished

Hydraulic buffers work on the principle of forcing oil from one chamber to another under high pressure. Restricting this oil flow results in the absorption of the impact energy.

A gas return spring is used to extend the buffer’s plunger after an impact.

What Buffers Offer You

• An engineered solution for impact energy absorption problems
• Very efficient impact energy absorption
• Can operate on a continuous basis over extended periods of time – multiple impacts
• Predictable outcomes
• Very low maintenance requirements
• Consistent protection for men, equipment and structures under impact conditions
