Abstract
A coal-cutting machine (1) having an all-round swivelling jib boom (6), on which cutting implements (17) are rotatably supported, and a loading platform (3) comprising a loading platform which can swivel about an axis (4) extending transversely to the longitudinal direction of the machine. The loading platform (3) is angularly, rigidly connected to the swing gear (5) for the swivelling of the jib boom (6) in a horizontal direction and is supported on the machine frame (1) so as to swivel, together with the swing gear (5), about the axis (4) extending transversely to the longitudinal direction of the machine. As a result of this construction which a particularly low overall height is made possible while safely preventing a collision between the jib boom (6) and the loading platform (3). A pivot axis (15) for the pivoting of the jib boom (6) in an essentially vertical direction, is preferably arranged between the swing gear (5), which is rigidly connected to the loading platform, and the rotatably supported cutting implements (17).
