Leyland-Metz turntable escape, 1938.
© Science Museum / Science & Society Picture Library
This engine drives a 500 gallon (2.270 litres) per minute turbine pump, which delivers water to the monitor at the top of the ladder, and also supplies power for the training, elevation, extension, and plumbing of the ladder, at the base of which are the controls and indicators. The turntable ladder can be extended up to 100 feet (30m). It can be employed in a variety of ways but its principal uses are as a water tower and to effect rescues from high buildings. Until 1961 this appliance belonged to the Lancashire Fire Brigade.
