(57) An area (1) is defined by a fixed border (2) located at the same height of the side
frames of pallets (3) in order to limit and guide them. On each pallet (3) a car (4)
can be loaded, or another object to be parked, such as a machine, a piece of furniture,
etc. The pallets (3) are alike, independent from one another and self-propelled, arranged
according to a plurality of rows and of columns on the area (1). The pallets (3) have
substantially rectangular shape and are capable of moving according to two orthogonal
directions, i.e. the rows and the columns. For their manoeuvre spaces (5) are left
free, each corresponding to the surface covered by each pallet (3). On a pallet (3)
a car (4) is loaded or unloaded in a zone (6) of the area (1) that can be used as
entrance or exit, near to which pedestrian platforms (7) are provided for getting
on or of the car (4). The pallet are self-propelled, by means of electric steering
drives on board and are independent from one another. Step movements in the two orthogonal
directions are controlled by a send-receive computing fixed unit.
