Abstract: An arrangement for the handling of drill string elements, such as tubes or rods, in drill rigs, comprising means for transferring the drill string elements between a magazine and the drill string axis, a drill string centralizer at the front end of an elongated support for guiding the drill string, a spinning device on said transferring means for gripping and rotating a drill string element, said means being adapted to axially displace the drill string element during rotation thereof, and a sleeve brake mounted on the drilling machine for nonrotatably holding a coupling sleeve when the adapter of the drilling machine is disconnected from the drill string.
