Energy Absorption and Vibration Isolation Products

Hydraulic Buffer


Deceleration of Large Equipment

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-orificed non-adjustable models are also available as well as optional fluids and seal packages to expand standard operating temperature range from (15º F to 140º F) to (-40º F to 210º F). 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.


Large Machinery Safety Stops Made Easy

ITT Enidine Inc.'s Heavy Industry (HI Series) buffers safely protect heavy machinery, cranes and equipment during the transfer of materials and movement of products.

The large-bore, high-capacity buffers are individually designed to decelerate moving loads under various conditions and in compliance with industry mandated safety standards. Control of bridge cranes, trolley platforms, overhead cranes, large container transfer and transportation safety stops are typical applications. Industry-proven design technologies, coupled with the experience of a globally installed product base, ensure deliverable performance that exceeds customer expectations.

Prior to HI Series buffer manufacture, computer-simulated response curves are generated to model actual conditions, verify product performance, confirm damping characteristics and generate unique custom-orificed designs that accommodate multi-condition or specific damping requirements.

The HI Series of buffers by ITT Enidine Inc. feature a nitrogen-charged return system that allows for soft deceleration and positive return in a maintenance-free package. The oversize bore area results in optimal energy absorption capabilities and increased internal safety factors. ITT Enidine Inc.'s state-of-the-art testing facilities ensure integrity of design and product performance.
