Enidine's HD/HDN Series of heavy duty shock absorbers protect equipment from large impacts in applications such as automated storage and retrieval systems as well as overhead bridge and trolley cranes. They are available in a wide variety of stroke lengths and damping characteristics to increase equipment life and meet stringent deceleration requirements.

Utilizing a special compact design, these shock absorbers smoothly and safely decelerate large energy capacity loads up to 8 million in-lbs. per cycle. These models incorporate an internal, air charged bladder accumulator, replacing mechanical return springs, providing a shorter overall length and reduced weight. The zinc-plated external components provide enhanced corrosion protection, while epoxy painting and special rod materials are available for use in highly corrosive environments. All of Enidine's heavy duty hydraulic shock absorbers are engineered to meet OSHA, AISE, CMMA and other safety specifications such as DIN and FEM.

ITT Enidine Inc.'s heavy duty industrial shock absorbers are offered with a wide variety of optional configurations, including bellows, clevis mounts and safety cables. Standard adjustable or custom-orifice non-adjustable models are also available as well as optional fluids and seal packages to expand standard operating temperature range from (15ºF to 140ºF) to (-40ºF to 210ºF). For easy maintenance, all sizes of ITT Enidine Inc.'s heavy duty hydraulic shock absorbers are fully field-repairable. These products also offer piston rod extension sensor systems for reuse safety requirements.
