Improved bag trolley, which being of the type that has a lower frame carrying wheels, whose frame is hingedly attached to an upper frame "U" inverted constituting the handle, is characterized essentially because the terminals of the arms of the upper frame have slots slides, by which play the articulation axes between the frame and frame, the latter comprising two protruding front hooks and having in addition to the above mentioned terminals of the upper frame concentric springs that, respectively, press on the axes that articulate the frame on the frame and on the front hooks of the upper frame, so that, in the assembly operation, the arms of the upper frame undergo a displacement with respect to the lower frame, made possible by the slots slides that the frame is provided, while, in that movement are compressed the springs, taking lu in this position, the fastening of the front hooks on the support beam of the bag provided in the lower frame, while uncoupling the hook from the cross beam, prior displacement of the upper frame compressing the springs and play of the articulatory axes on the collisions, allows the folding of the upper frame on the frame, until it is in a folding position parallel to such a frame.
