The Beam Engine
This steam-powered, steel beam engine and the engine house of which it forms an integral part are central to the Prestongrange colliery site, now a historical monument to the Scottish coal industry.
The massive pump, capable of shifting 650 gals of water per minute, is of a design most common in Cornwall, where it was originally developed to use high-pressure steam with greatest efficiency.
The cast-iron beam stands at a height of 27ft, is 33ft long and 6ft 4in deep, and weighs more than 30 tons. The stroke of the beam is 12ft, giving the pump-rams one of 10ft, and the normal working speed would have been three and a half strokes per minute.
The pump was modified in 1895 and was in full use until 1954.

can't beat the picturesque power of the analog machine!! very impressive in an almost intimidating way, those giant iron wheels resting under a dramatic sky! and the low point of view even enhances their impact – great! greetings, sabine.alberto16-menuder 07/07/2015 10:08
