A balanced luggage van includes wheels, a wheel frame and a main van frame. The wheels are mounted on the lower side of the main van frame via the wheel frame. The axle components of the wheels are connected with the lower end of the wheel frame. A rotating shaft is further provided in the center of the main van frame, and the upper end of the wheel frame is rotationally connected with the main van frame by the rotating shaft. When the baggage van passes through various oblique and bumpy roads, the carrying platform of the van can be always kept horizontal via operations, and it is quite reliable in stability. |
