A handling device for handling drill string components (8, 8 ',8") in respect of a rock drill rig (1), which includes a rotator device (4) being supported moveably to and fro on a feed beam (2) and being arranged for rotation and driving of a drill string component, wherein the handling device includes a gripper unit (11) for gripping drill string components (8, 8 ',8") to be placed into or be removed from an active drill string position (A) of the drill rig. The gripper unit (11) is swingably supported around a first swing axis (Al) in the region of the feed beam between: a) a first position aligned with said active drill string position (A), and b) a second position aligned with a delivering position for drill string components to be placed into and removed from said active drill string position (A), wherein the handling device includes a swing arm (7), having support means (7') for supporting a drill string component and which is swingable around a second swing axis (A2) between a loading position for drill string components and said delivering position, wherein a guiding beam (19) is fastenable at its end regions in connection with the respective regions of the first and the second swing axis (A1;A2), and wherein the guiding beam (19) forms mechanical stops for the gripper unit (11) in said second position as well as for the swing arm (7) in the delivering position. The invention also concerns a rock drill rig and a method. |
