The group's principal activities are to design, develop, manufacture and market shock absorption, rate control and energy storage devices for use in various types of machinery, equipment and structures. the group has six major products: seismic dampers, fluidicshoks, crane and industrial buffers, self-adjusting shock absorbers, liquid die springs and vibration dampers. seismic dampers are designed to ameliorate the effects of earthquake tremors on structures. fluidicshoks are small, extremely compact shock absorbers for use in defense, aerospace and commercial industry. crane and industrial buffers are used for industrial application on cranes, ships, railroad cars etc. self-adjusting shock absorbers are designed for high cycle application primarily in heavy industry. liquid die springs are used for manufacture of tools and dies. vibration dampers are used in the aerospace and defense industries. products are sold to customers in domestic and foreign markets.
