Abstract

A device for handling drill string components for a drill rig. A slide is arranged displaceable on a longitudinal guide. A grip unit is swingable between a first position for receiving and delivering of drill string components beside the drill rig and a second position for assembling and disassembling of drill string components in the drill rig. The grip unit includes a rotator unit for rotation of a gripped drill string component. A rotational actuator supported by the slide has a rotational axis forming an angle with the length guide. A swing unit includes a first link portion that is connected to the rotational axis. A second link portion is connected to the grip unit and a swing joint portion.
