The Anderton Shearer Loader is a coal cutting machine which was used in the UK coal industry after 1953. The Anderton Power Loader with its cutting drum up to five feet in diameter was patented in 1953. It was successfully used throughout the British coalfields and by 1966 cut half the coal produced and by 1977 it produced 80% of the coal mined in Britain.
Horizontal cutting drums are mounted on the face side of the machine, laced with cutting picks and rotating in a plane parallel to the face. If the AFC is pushed towards the face as the cutting drums are rotated and the shearer travels along the face, it is able to cut into the face for the full web width, moving along a snake in the AFC.

Mar 21, 2011#0183;#32;I have a gut feeling that what Anderton and his team did was to add a plough to an existing machine concept, which then altered the function of a shearer as a coal cutter to a cutter loader. The basic concept of a shearer having no doubt been influenced by the much earlier undercutting ''bar'' machines in the first place.
