This big ton spring assembly is designed for a local area refinery, and is fabricated from carbon steel components with a painted finish. The top of the load flange has three PTFE, 25% glass filled slide plates. The base is 96″ x 18″ and the installed height is 24″. This big ton spring will be utilized to support heavy (in excess of 76,000 lb.) loads where a standard variable spring would be undersized. The big ton spring design includes an array of parallel coils within one frame to produce large load carrying capacity while maintaining the same spring rate. The assembly is designed to withstand an operating load of 76,800 lb. and has a downward travel of 0.894″.
Prior to fabrication, each of the coils were individually tested to insure correct spring rate and load capacity. After fabrication, the entire assembly was tested throughout the entire load and travel range.
