ABSTRACT OF THE DISCLOSURE This public works machine, such as a self-propelled hydraulic loading shovel comprises a lower chassis provided with a pair of wheels and with a pair of liftable or retract- able stabilizers, so that this lower chassis can rest on the ground selectively simply by its pair of wheels or both by said pair of wheels and said stabilizers, and a superstructure carrying a working attachment and mounted to rotate on said lower chassis, said superstructure also carrying a pair of wheels which are movable between a position in contact with the ground and a lifted position. The machine is self-propelled when two pairs of wheels are in contact with the ground. For loading materials or the like, the wheels of the superstructure are lifted and the machine rests on the ground through the pair of wheels of the chassis and the stabilizers.
