Abstract
The loading ramp (2) of a partial-cut shearer machine has at least one lateral extension arm (6) which is pivotable relative to the loading ramp (2) in the horizontal direction about a vertical axis (7) and has a continuous conveyor formed by a conveyor worm (12). The extension arm (6) is pivoted by actuating a hydraulic strut (8). The drive motor (11) for the conveyor worm (12) is arranged at the discharging end of the extension arm (6).
