Board detailing the action of the control valves of the Swing Bridge over the river Tyne Newcastle north east England UK
Construction of the The Swing Bridge began in 1873 and it was completed in 1876. It was designed and built by Sir Armstrong and Co. Ltd. The bridge rotates on a turntable rather like a gun turret, and is driven by hydraulic machinery powered by large water filled accumulators within caissons sunk below the river. All of the machinery was duplicated, so that a failure of one element would not prevent operation. Originally the accumulators were pressurized by steam engines, but in 1959 the engines and pumps were replaced by electrically driven pumps. Otherwise the machinery is as built. This photo, taken in the west engine room, shows the notice board that explains the function of each hydraulic control valve. The gauge shows the operating water pressure.
