PT&P designed G-Type variable spring supports for a paper manufacturing plant in Minnesota. The variables are comprised of two standard spring housing coil subassemblies joined together with an intermediate bridge assembly. The bridge assembly is customized to match existing site conditions which allows for use in applications with limited space or interferences. The variables are fabricated from carbon steel with a hot-dipped galvanized finish. The assemblies were designed for a total operating load of 1,348 lb. with an upward design travel of 0.8013″. Each assembly underwent a standard load test prior to shipment.
