Trolley constituted by a lower frame receiving rolling units 2, vertical walls 4 and stacking means which are props 15 which slide with respect to the walls 4, between a low retracted position and a high position allowing them to receive the frame of a trolley having the same dimensions. Each prop is constituted by two uprights 14 sliding in the lateral framework tubes 10 of the wall 3, connected by an L-section cross-piece capable of receiving the corresponding side of the frame of the trolley of the same dimensions to be stacked. The uprights 14 are held in the high position by bolts 19 whose shafts 20 traverse the lateral framework tubes 10 of the wall 4, on which the ends of the uprights 14 rest. Small rules running along the shafts 20 end with a hight stop piece. Such a trolley is used for goods handling. <IMAGE>
