<p>Carrier arms, armed with rollers, swivel at both ends of the machine body. This moves partly in the cutting field with its back filling side led on the conveyor and is guided on the floor. The roller cutter loader excavates narrow seams in underground mines. The arms (3) are in the form of cutting chain booms, mounted on the machine body on the coal face side. The cutter rollers (10) are on the arms on the backfilling side, being driven by cutter chains (4), or by gear wheels, with the circulating cutter chains retained.</p> |
