At the end of the set of booms (10) at least a drilling apparatus (19) can be attached. A front part (4), to which the set of booms (8) is fitted from the end opposite to the drilling apparatus (19), attached in front of the carrier (1), in the direction of travel of the crawler treads (11). The set of booms (8) is attached to a rotation ring (9), with the aid of which a good reach is made possible for the device.
