Abstract: A movable shelf arrangement has individual shelf members and tracks connected to the floor and extending parallel to one another perpendicular to the longitudinal extension of the shelf members. A set of wheels is connected to each one of the shelf members for moving the shelf members on the tracks. At least some of the wheels of the set of wheels are driven. A drive is connected to each one of the driven wheels. A sensor arrangement is connected to each one of the shelf members for sensing alignment and lateral displacement of the wheels relative to the ideal line of movement on the tracks. A drive control unit is connected to each one of the driven wheels for receiving corrective control signals based on the detection signals of the sensor arrangement in order to correct the driven wheels with respect to alignment with the ideal line of movement.
