Abrégé

The invention relates to a shearer loader for longwall mining, having a machine body (1) which is movable along a face conveyor (7) in the longitudinal direction (S) of the longwall by means of a drive device and having at least two drum arms (4) which are pivotally attached to the machine body (1) and at the free ends of each of which a cutting drum (5) is rotatably mounted, the machine body (1) having a support structure which is formed by a bracing of at least two support elements (3) in the longitudinal direction (S) of the longwall, and the machine body (1) comprising functional units (2). The aim of the invention is to further develop the shearer loader in such a way that the structural design of the machine body (1) allows larger dimensions of the shearer loader in order to work face thicknesses of 10 m and more. According to the invention, this is achieved in that the support elements (3) are designed as frame elements (8), each of which has an installation space (9) for the functional units (2).

Abrégé

The invention relates to a shearer loader for longwall mining, having a machine body (1) which is movable along a face conveyor (6) in the longitudinal direction (S) of the longwall by means of a drive device and having at least two drum arms (4) which are pivotally attached to the machine body and at the free ends of each of which a cutting drum (5) is rotatably mounted, the machine body (1) having a support structure, and the drive device having two or more drive units (3), each of which has at least one drive motor (3c), a winch transmission (3b), and a wheel house transmission (3a). The aim of the invention is to develop the shearer loader such that the shearer loader is more flexible overall during use. For this purpose, the invention proposes that the support structure of the machine body (1) is formed by a frame element (11, 8), and the drive units (3) can be fixed to the frame element (11, 8) at an adjustable height via connecting means.
