Haig Colliery Mining Museum, Whitehaven

The Home of the only fully restored and operational Bever Dorling Winding Engine in the world.
Augustus Bever and Horace Dorling formed Bever Dorling & Co Ltd in 1906. They had moved from W.J.Cardwells in Dewsbury, to Bradford in 1902. An engine built by Cardwells, Sara, is still on display at the Providence Mills in Dewsbury. The company was first listed as Colliery Engineers, and moved to bigger premises at Bowling Back Lane, Bradford in 1909. Little more however, is known about the company.
The company catalogue was extensive, with machinery being manufactured for many uses in mining and also sugar plantations, among others. The only engines known to survive in the world, however, are the two steam engines at Haig, and an electric winder in Hong Kong operating an inclined tramway.
