In the present publication, an air-cushion element (1 to 5) for air-cushion transport equipment is described. The element comprises a disc-shaped frame (1), a ring-shaped rubber bellows (2) arranged air-tight underneath and frame (1), a membrane (4) with a high number of small perforations (5), attached to the bottom edge of the rubber bellows (2) so that the frame (1), the rubber bellows (2), and the membrane (4) define a space (6) for outflowing air, and at least one opening (3) for the feeding-in of pressurized air into the space (6). According to the invention, in this connection, the perforations (5) in the membrane (5) are arranged irregularly in relation to orthogonal or polar coordinates, for example, along a so-called spiral of Archimedes. Air-cushion transport equipment with air-cushion elements in accordance with the present invention can also be used when there is a discontinuity or a difference in level between two faces, such as in the case of slots in the floor or between platforms that can be raised and lowered.
