The HDA 3.0 x 8 is a heavy duty adjustable shock absorber designed for high-energy impact applications, with a stroke length of 8 inches (200 mm) and a maximum shock force of 50,000 lbs (222,400 N). It features a maximum energy absorption rating of 160,000 in.-lbs./cycle (18,100 Nm/cycle) and a maximum cycle rate of 60 cycles per hour. The unit has a front flange mounting configuration with dimensions of 25.2 inches (640 mm) in length, 16.3 inches (415 mm) in width, and 4.4 inches (112 mm) in thickness, weighing 57 lbs (29 kg). It includes an adjustable damping setting range determined by impact velocity, with a maximum allowable propelling force of 25,000 lbs (111,200 N). Rear flange mounting is not recommended for strokes of 12 inches or longer.
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.
