<p>The device (1) has a chassis (2) mounted on a road of a vehicle, and a sliding arm (5) mounted slidingly with respect to a pivoting arm (3) between a retracted position and an unfolded position. A control unit (8) unloads an object in two phases, where the sliding arm is maintained in the retracted position with respect to the pivoting arm, in one of the phases. The pivoting arm is maintained in the unfolded position with respect to the chassis, and sliding arm moves from retracted position to the unfolded position with respect to the pivoting arm, in the other phase.</p> |
