Abstract: The invention provides a process and an installation for storing objects with automated handling.The installation comprises a storage area (10) formed by a plurality of horizontal and parallel beams (14) resting on supports (18) which define therebetween and under the beams at least one longitudinal passage track extending in a direction perpendicular to the beams and at least one mechanized handling vehicle (12) adapted to move along said track, said vehicle being equipped with conveyors (86,88) for driving in a transverse direction, perpendicular to the direction of movement of the vehicle, and being adjustable in height between a low position in which it may pass freely under the beams and a high position in which the drive conveyors raise the object to be moved.
