Abstract
A double-head drilling machine is disclosed, which by changing over or converting small component units can cooperate with drill or drill pipes of different diameters. To this end, drive carriages (,) operating on drills or drill pipes, for example, comprise a carriage base element (,), to which a drive unit (,) is releasably fitted. The drive unit (,) can thus be replaced by a different drive unit having essentially the same geometry, which is designed for operating with a drill or drill pipe having a different diameter.
