Abstract
A roll cutter loader is guided on a plane guide and has a machine frame with cutter rolls pulled by a plane chain. The machine frame is subdivided into two machine joint elements each with a cutter roll and roll drive assembly. The two machine joint elements are lower in structural height than the cutter rolls and are adjustably connected together relative to the floor, on the one hand via a joint and on the other hand via a setting device. In this way maneuverable, adaptable and compact construction is achieved, so that the roll cutter loader can be used to mine low mineral lodes.
