The constants range in size from 25" to 27" in height, 52" to 67" in length, and 25" in width. Their load capacities range from 10,300 lb. to 13,000 lb. with vertical movement ranging from 3" to 4-1/2". All constants were fabricated from A-36 carbon steel, and went through standard load and travel testing per MSS Standards prior to shipment.

To prevent twisting of the fluid container, the support system is designed to allow for “level” vertical movement. This was achieved by using a special system composed of three U-Type constant units. Each unit employs two springs working in parallel with a common large base plate and a load flange to support the entire 5' width of the container.

The spring coils were coated in neoprene, and all the other major components were hot dip galvanized to inhibit corrosion. These constants were constructed primarily from carbon steel with the use of stainless steel and PTFE, 25% glass filled slide plates. Want to learn more about constant springs?
