| Type: | Big Ton Spring Supports |
| Material: | Carbon Steel w/ HDG Finish |
| Design: | 13,457 lb. Load | 0.35" Vertical |
| Testing: | Load and Travel Tests |
These big ton springs are used in supporting large heavy units such as compressors, vessels and pumps in power and petrochemical plants. The housing and frame are fabricated from carbon steel and hot-dipped galvanized, and the spring coils are dipped in a neoprene coating. The units are 48” x 40” x 20”. The big ton spring support is designed to allow limited movement of 0.35″ upwards and an operating load of 13,457 lb. This design saved the customer from having to entirely redesign the piping system, which saved them thousands of dollars. Load and travel tests were performed prior to shipping to an oil refinery in Australia.
