Handing device for handling drill string components (8) in a rock drill rig (1 ), wherein the handing device includes a magazine (6) for storing drill string components (8) to be introduced into and removed from a drill string position (A) of the drill rig. The magazine includes, in the region of the loading position (L), a transfer unit (41 ) for separation of a drill string component being positioned on said support means from an adjacent drill string component and to transfer the separated drill string component to the loading position. The transfer unit includes movable stop elements (47) for said separation of drill string components. The transfer unit includes a plurality of pivot arms (42) being pivotal around a pivot axis (V), being parallel to said axial direction, from a first position (Fig. 3), wherein the pivot arms lie against a drill string component being closest to the loading position on said support means (44'), to a second position (Fig. 4), wherein the pivot arms (42) allow bringing down the separated drill string component to the loading position (L). The invention also relates to a rock drill rig. |
