Custom Big Ton Springs with Hydraulics
Rilco Manufacturing designed and fabricated custom big ton springs for a refinery in California. These springs were fabricated from carbon steel and included four powder coated spring coils and four hydraulic cylinders. The cylinders connected to a common hydraulic manifold by tubing and fittings. See close-up of the internal components below.
The big ton springs were designed for a cold load of 45,900 lb., a hot load of 43,000 lb., and a retracted load of 61,900 lb. Additionally, they were designed with a spring rate of 16,000 lb./in. and an upward travel of 0.2 inches. The big ton springs measure 20" high x 18" wide x 52" long.
They were fabricated to support large pressure vessels in the refinery. When the hydraulic cylinders are activated, the spring coils self-retract down to facilitate the movement of the vessel for maintenance.
The completed big ton springs, shown above, underwent load testing prior to shipping to ensure quality control.
