G-Type Variable Spring Supports Designed for a Chemical Plant
PT&P designed G-Type variable spring supports for a chemical plant in Texas. The variables are comprised of two standard spring housing 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 23,522 lb. with a downward design travel of 3/8″. Each assembly underwent a standard load test prior to shipment.
