The carrier vehicle comprises a chassis (2) and four wheels, all driving wheels, with two wheels (4) situated on the right-hand side of the chassis (2) of the vehicle and two other wheels (5, 6) situated on the left-hand side of the chassis. The four wheels are of the independent suspension type, having a jack-controlled height, and each comprise rotation-drive means, especially hydraulic motors. The chassis (2) receives, at the front and at the rear, working equipment, such as drilling arms (25, 26) with respective guides (27, 29), the basic position of which is horizontal and transverse to the direction of displacement (F) of the vehicle. This carrier vehicle is applicable to the realization of a machine which can be used in mine galleries of low height.
