The invention discloses a four-wheel flatbed cart capable of crawling short-step stairs. The cart comprises a cart front-end flat plate, a cart rear-side rotating plate, a bearing plate, a rotating shaft, a front wheel driving mechanism arranged at the lower end of the cart front-end flat plate, a rear wheel driving mechanism arranged below the rear end of the cart front-end flat plate, a supporting frame mechanism arranged above the rear wheel driving mechanism, and an auxiliary air pressure mechanism located on the left side of the supporting frame mechanism. The cart front end flat plate and the cart rear side rotating plate are rotationally connected through the rotating shaft, the front wheel driving mechanism comprises a front wheel rotating assembly used for rotating a front tire, and the auxiliary air pressure mechanism comprises a pneumatic starting assembly used for controlling starting pneumatic pressure. According to the technical scheme, the flat cart can adapt to steps with different heights and climb the steps, the levelness of the flat plate for bearing goods can be adjusted in a self-adaptive mode on the steep slope, and therefore it is guaranteed that the goods cannot topple over when the cart climbs on the steep slope, and the goods transporting efficiency is guaranteed.
