Abstract
A handling device for handling drill string components with respect to a rock drill rig including a rotator device supported on a feed beam and arranged to rotate and drive a drill string component. A gripper grips drill string components. The gripper is swingably supported around a first swing axis between: a first position aligned with the active drill string position, and a second position aligned with a delivering position for drill string components. A swing arm includes a support configured to support a drill string component and is swingable around a second swing axis. A guiding beam is fastenable at end regions in connection with respective regions of the first and second swing axis. The guiding beam forms mechanical stops for the gripper in the second position and for the swing arm in the delivering position. Also, a rock drill rig and a method.
