PT&P custom-designed big ton spring supports with stainless steel rollers for a chemical plant in Brazil. The frame is fabricated from carbon steel and the shim plates are 2205 duplex stainless steel. The design specified that these big tons are placed in a large “oil pan” that was fabricated from AR400 steel. AR400 steel is abrasion resistant and has a minimum hardness of 360 on the Brinell scale and a nominal hardness of 400. The stainless steel rollers are designed to fit inside the “oil pan” and the big tons are placed on top of the rollers. Oil is then placed inside the pan providing continuous lubrication for the assembly while accommodating the axial or lateral movement of the structure. These big ton spring assemblies include special coils and neoprene drip shields to protect the coils and oil in the pan from debris. The big tons are 26-1/2″ x 33″ x 26-1/2″ with a movement of 0.499″ down and a spring rate of 13,450 lb./in. They are designed for an operating load up to 78,318 lb. and underwent load testing prior to shipment. PT&P, along with our team of engineers and designers, specializes in making the impossible, possible. Over the years, there are many instances where our clients have come to us with unique and unusual applications requiring a product not yet developed or requiring the modification of an existing product.
