The HDN 3.5 x 12 is a heavy duty non-adjustable shock absorber designed for high-energy impact applications, with a stroke of 12 inches (300 mm) and a maximum energy absorption capacity of 626,500 in.-lbs./cycle (70,800 Nm/cycle). It features a nominal return force of 270 lbs. (1,200 N) without the bladder accumulator option and 1,010 lbs. (4,480 N) with it, and a maximum return force of 67,500 lbs. (300,250 N). The unit measures 33.9 inches (862 mm) in length, weighs 117 lbs. (53 kg), and has a maximum cycle rate of 60 cycles per hour with the BA option. Mounting options include front and rear flange or foot configurations, with rear flange mounting not recommended for strokes of 12 inches or longer. The device is rated for impact velocities up to 180 in./sec. (4.5 m/s) under linear conditions, with higher velocities requiring factory consultation.
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.
