The original raising mechanism was powered by pressurised water stored in several hydraulic accumulators. The system was designed and installed by Hamilton Owen Rendel[26] while working for Sir W. G. Armstrong Mitchell & Company of Newcastle upon Tyne. Water, at a pressure of 750 psi (5.2 MPa), was pumped into the accumulators by two 360 hp (270 kW) horizontal twin-tandem compound stationary steam engines, fitted with Meyer expansion slide valves. Each engine drove a force pump from its piston tail rod. (Wikipedia)
