The basic concept of a shearer having no doubt been influenced by the much earlier undercutting ''bar'' machines in the first place.
Mining Picks. Mining picks body made from cold extrusion of high quality 42CrMo steel, the density is high, and there is no decarburization. It is mainly used for coal mining and drilling of roadway, tunnel and ground ditching. Used together with shearer, roadheader, pavement planer, etc.
The downdrives are bolted to the traction cases in an arrangement that permits the custom fitting of the shearer within the armoured face conveyor and roof support envelope; a wide selection of downdrives can be fitted to the shearer to suit both mining conditions and the armored face conveyor selected.
Pulled along the face astride the conveyor, the shearer bore a series of disks fitted with picks on their perimeters and mounted on a shaft perpendicular to the face. The revolving disks cut a slice from the coal face as the machine
