The device according to the invention is particularly intended for the manufacture of the carriage of the hike. The device is constituted by a shaft (2) on which are welded three forks (5) of the same opening having either a central wheel (6) or two lateral wheels (7) which transforms the carriage in the wheelbarrow to a wheel or trolley to two wheels. The device is orientable about two screws (10), making it possible to adjust the overall balance of the carriage by modifying the angular position of the axis (2), - latter is predetermined by the stops (9) on which rest of the struts (8). The uprights (3) of the carriage are extended by the rollers (11), which converts the carriage in the stroller when the four wheels applied simultaneously on the ground. The carriage is converted into a suitcase wheel when the forks (5) and the struts (8) are deployed on the wheels (6) and (7) pressed against the back of the carriage, the telescopic drawbars (16) then being retracted along the uprights (3).
