The handing device includes a magazine for storing drill string components to be introduced into and removed from a drill string position of the drill rig. The magazine includes, in the region of a loading position, a transfer unit for separation of a drill string component being positioned on a support from an adjacent drill string component and to transfer the separated drill string component to the loading position. The transfer unit includes a plurality of pivot arms being pivotal around a pivot axis, being parallel to the axial direction, from a first position. The pivot arms lie against a drill string component being closest to the loading position on the support, to a second position.
