The HDN 3.0 x 8 is a non-adjustable heavy duty shock absorber designed for high-energy impact absorption in industrial applications. It has a nominal stroke of 8 inches (200 mm) and can absorb up to 316,100 in-lbs. (35,700 Nm) per cycle at a maximum initial shock force of 170 lbf (755 N). The unit weighs 57 lbs. (26 kg) without the bladder accumulator option and features a 3.0 inch bore. Dimensions include a return force of 650 lbf (2,895 N), an overall length of 25.2 inches (640 mm), a front flange diameter of 10.0 inches (253 mm), and a rod diameter of 1.8 inches (46 mm). It is rated for a maximum cycle rate of 30 cycles per hour without the bladder accumulator option and requires consultation for impact velocities over 180 in./sec. (4.5 m/s).
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.
