Bridge-Cable Dampers

Cable-stayed and extradosed bridges not only help create a smooth flow of traffic in an urban environment, their elegant design adds to the beauty of the landscape. The Sumitomo Cable Damper protects a bridge by decreasing wind-and rain-induced vibrations that threaten the safety of the cables with a damper that absorbs a high degree of energy and improves the durability of the bridge. Due to the high degree of damping provided by the system, cable vibration can be controlled and by decreasing the stress fatigue placed on cable stays, improved levels of durability and safety can be reached. Sumitomo's damper systems feature designs and specifications which can be applied to a variety of structures and conditions, helping to create a symbiosis between civil engineering and nature.
