A handling device for handling drill string components (8, 8 ',8") in a rock drilling rig (1), wherein the handling device includes a gripper unit (11) for gripping drill string components (8, 8 ',8") to be put into and be brought out from the rock drilling rig, and wherein the gripper unit (11) includes grippers (12,13,14) operational for gripping components positioned in a gripping position, which defines a grip position axis (G). The gripper unit (11) is supported swingable between: a) a first position, wherein the gripper unit is positioned for engagement with an end portion of a first drill string component (8') and an end portion of a second drill string component (8") in and aligned with said active drill string position (A), and b) a second position, wherein a gripper unit (11) is positioned for engagement with an end portion of a drill string component in a delivering position for drill string components that are to be brought into respectively taken away from said active drill string position (A). The invention also concerns a rock drilling rig and a method. |
