Abstract:
A merchandise presentation arrangement (11) contains a lifting bottom (33) carried by lifting cushions (32) that are arranged on top of one another and can be expanded up to a functional height by supplying compressed fluid. Each lifting cushion (32) is assigned a control valve and a pressure sensor that are connected to a control unit. In an automatic program sequence, compressed fluid is supplied to a lifting cushion (32) until a reference pressure value corresponding to the total weight of the merchandise is reached, wherein a switching pressure value is calculated from said reference pressure value for each lifting cushion (32).
