This publication describes a trolley, the inside dimensions of which can easily be adjusted for products of different sizes. The bars of the trolley on the side walls are rotatable and the bar is of rectangular profile. When the bar is in an upright position, that is to say when the short side in its cross-sectional profile points upwards, the internal dimensions of the trolley are equal to the distance between its vertical side walls. When a trolley of narrower inside dimensions is required, the bars are turned into the horizontal position, the short sides of their profiles pointing towards the inside of the trolley. The inside dimensions of the trolley then diminish from both sides with a measurement corresponding to the difference in the side heights of the profile section. <IMAGE>
