ABSTRACT:
This invention relates to a drilling and/or lifting machine, in particular a track-mounted drilling and lifting rig. The machine comprises a movable carriage, a first lifting and/or tool carrying device (A), a support (2, 4, 5) mounting the first lifting and/or tool carrying device (A) on the carriage to enable the first lifting and/or tool carrying device to be positioned in a selected one of a variety of different positions and a second lifting and/or tool carrying device (B) mounted on the carriage so as to be movable either with or independently of the first lifting and/or tool carrying device (A). The support is rotatably connected by a bearing member (3) to the first lifting and/or tool carrying device and connecting mechanism (6, HH', PP') connects the support to the first lifting and/or tool carrying device (A), the connecting mechanism being movable to rotate the first lifting and/or tool carrying device (A) relative to the support.
