Colliery Steam Winding Engine

Elliot Colliery, New Tredegar, was opened in the late 1880s by the Powell Duffryn Steam Coal Company and was the first of its modern "Super Pits" to be sunk in the Rhymney Valley.

The East Pit winding engine was built in 1891 and used to raise and lower the cages in the shaft. It was originally a twin-cylinder horizontal engine but was extended in 1904 with two high pressure cylinders. The winding drum is of conical or "Diablo" type.

At its peak, in 1912, Elliot Colliery employed some 2811 men and produced 1,305,000 tons of coal per year whilst the haul speed of the engine could reach a maximum 92 feet or 28 metres per second to lower the men and raise the coal.

Despite the widespread conversion to electrical power at other collieries, this winding engine continued to be powered by steam until Elliot Colliery closed in 1967. A first phase of restoration has been completed and work continues.

Decades of engineering history are illustrated in this single machine and it is testimony to the miners and their families who lived and worked with it for so many generations whilst engaged in the production of the steam coal exported worldwide from South Wales
