摘要
In a drive arrangement for the loading arms (5) of a loading ramp for a heading machine or longwall shearing machine, each loading arm (5) is rotatably supported in off-center position on a rotary disc (7) and extended beyond its axis of rotation (6) by guide arm (10) arranged so as to swivel around a bearing point on one end of a steering lever (11) . The heading machine or longwall shearing machine has--for broadening its loading ramp--laterally outwardly swivellable parts (2) having arranged thereon, in a manner preventing angular movement, an arm (14) extending beyond the pivotal axis (4) of the extendible part (2). For automatic adaptation of the removal width of the loading arms (5) to the selected working width of the loading ramp, the other end of the steering lever (11) is hinged to the free end of the arm (14) connected with the outwardly swivellable part (2).
