Summary:The loading ramp (1) of a heading machine or longwall shearing machine has swivelable loading arms by means of which the cut material is removed onto a conveying means. The surface of the loading ramp (1) can be increased by outwardly swivelling of parts (2). The loading arms (5) are driven by using a pivotal point (6) on a rotary disc (7), noting that a further swivel point (12) is provided outwardly of the circle described by a rotary pivotal point (6) on the rotary disc. The loading arm (5) is guided in a shiftable manner at the swivel point (12) and sweeps when driving the rotary disc (7) over a removal area (15, 18) defined by the relative position of the pivotal point (6) and the swivel point (12). The swivel point (12) is connected with the laterally extendable part (2) and is displaced together with the laterally extendable part (2) thus varying the removal area (15, 18).
