In 1985 Foster Yeoman Ltd brought into use a giant walking crusher at its Merehead Quarry (Torr Works). The crusher was built by Orenstein and Koppel and is equiped with a Fuller Traylor 54 inch primary crusher capable of producing 22,500 tonnes in a single shift. The machine weighs in at 1,050 tons and is the height of a seven story building. It is moved around the quarry floor by "walking" cylinders and is powered by electricity, delivered byt a trailing cable.

Want to see how stone was loaded and overburden cleared in the 1940s? Take a look at this film of a Chaseside Hi-loader at work in Holwell Quarry, Nunney. The short 16mm colour film was made by managing director George Coleman and is a real gem.
This home movie of Asham Quarry at work was shot by Trevor Craddock in the early 1960s on Super 8 colour film. It shows a very dusty crushing plant and a Ruston Bucyrus 33-RB filling dump trucks at the quarry face. Also includes anecdote of former quarryman Ted Philips on "darsty" Asham.
