Abstract
In a cutting machine (2), including rotatably mounted cutting or shearing tools (19), a loading ramp and a hauling means (4) extend in a direction towards a mine face for receiving and hauling cut or sheared material. The cutting or shearing tools (19) are mounted on a slide which is displaceable on guides extending in the longitudinal direction of the machine. The guides are comprised of tubes or rods connected with a machine flame in the region of the track-laying gears (1), preferably within the track-laying gear frame. The slide is comprised of longitudinal spars (10) and a crossbeam (9) for mounting the cutting or shearing tools (19). The machine frame, at least in its front region adjacent the crossbeam (9), is designed as a box section (3), within the clear width of which the hauling means (4) is guided in a manner so as to be displaceable in the longitudinal direction of the machine.
