A lift truck comprises a chassis (1) movable on wheels (2) and a rotating platform (3) which supports an operating arm (4); stabilizing means are provided for resting on the ground and positioned at the front as well as at the back. The stabilizing means consist of two pairs of two telescopically extensible arms (5), each one comprising a first segment (6) and a second segment (7). The arms (5) have their ends hinged to opposite sides of the chassis (1), so as to swivel about parallel axes, and have the opposite free ends intended to lean against the ground by means of plates or stabilizing feet (8). The two arms (5) of each pair are arranged side by side at a short distance from each other on parallel planes and are individually bound to the chassis (1) by means of hydraulic cylinders (11). Control means are provided to control at least the return movements of each pair of arms (5) to a folded, contracted configuration, according to a predetermined sequence which provides that, for each single arm (5), full retraction of a respective second segment (7), at least for a predetermined portion of the final part of its return stroke, is carried out only after that the first segment (6) of the other arm (5), belonging to the same said pair of arms (5), has reached a final folding position.
