The folding trolley, for carrying various types of loads that can be pushed by hand, consists of upper and lower load-carrying platforms (1, 3) linked by a collapsible frame on wheels or rollers (4). The upper platform is held up by lateral supports (9, 13) with the supports (9) at the front of the trolley connected to a handle (10). At the point where the supports join the handle here are stay rods (12) connected to the rear supports (13). Pushing the rear end of the top platform down collapses the rear supports when a downward pressure is applied to the handle. At the same time the lower platform and a central transverse hinge fold upwards, allowing the trolley to fold into a compact unit. ADVANTAGE - Design and operating simplicity.
