A handling device for handling drill string components (8,8',8") in a rock drill rig (1) which includes a rotator device (4) being arranged for rotation and driving of a drill string component and being supported movable to and fro on a feed beam (2), wherein the handling device includes means for introducing drill string components into respectively remove drill string components from a drill string position (A) of the rock drill rig. The handling device includes a guiding beam (19) which includes a longitudinal guide (42). A gripper shuttle (40) is drivingly displaceable along the longitudinal guide, wherein the gripper shuttle includes a pivotally arranged guiding gripper (41) for gripping a first end region of a drill string component. The gripper shuttle carries a drive motor (45) for driving a drive wheel (44), and the drive wheel (44) is disengageable to allow essentially free movement of the gripper shuttle along the longitudinal guide (42). The invention also concerns a rock drill rig. |
