Abstract (en)
The machine has a leader (10) arranged on a chassis (2) for the longitudinally displaceable guidance of a drive head. A pivot drive (30) is provided for the pivoting of the leader about a pivot axis (6). A locking unit is displaced between a position, in which it fixes the leader on the chassis in a rotationally fixed manner about the pivot axis, and another position, in which the leader is released. A setting device is provided for the remote-controlled displacement of the locking unit.
