The trolley (1) has four bars (4) upwardly protruded from respective corner regions of a rectangular trolley base element (2). Multiple shutter elements (13-16) are arranged an upper or lower end portion of narrow sides (5, 6) and longitudinal sides (7, 8) in a vertical axis direction (Z) of the trolley.
