Abstract A storage rack installation having a rank of movable storage racks disposed in lateral juxtaposition and adapted to be shifted individually or in groups by associated drive means to open an access passage between any two selected neighboring racks. Each rack is provided with a reversible motor and is mounted on a plurality of wheels at least one of which is coupled to the associated motor. Control means are provided comprising a common control unit which determines the direction of rotation of the motors of the single or group of racks that is to be shifted, by reference to the position of two-way switch means of which one is associated with each rack, and which switch means adopt an open or closed position depending upon the existing position of the rack with which they are associated.
