A widely used cutter loader in which the ordinary jib of the longwall coal cutter is replaced by a shear drum which cuts a web from 16 to 22 in (40.6 to 55.9 cm) depending on its width. The machine travels on an armored conveyor and requires a prop-free front for working. It shears the coal in one direction and the front coal is loaded by a plow deflector, and then returns along the face (without cutting) and loads the remainder of the broken coal. The ordinary Anderton is suitable for coal seams more than 3 ft 6 in (1.1 m) thick.
