The invention relates to a precast concrete carrier vehicle which comprises a travelling mechanism, a storage bin mechanism, a storage bin dumping actuating mechanism, a rail mechanism, an electric control mechanism and a bracket mechanism. When the precast concrete carrier vehicle is used, a bucket driven wheel unit travels on the rail mechanism under the driving of a dragging vehicle, and then the bucket driven wheel unit drives the storage bin mechanism, the storage bin dumping actuating mechanism, a travelling control cabinet and the bracket mechanism to travel following the bucket drivenwheel unit, so as to transport the precast concrete stored in a cylinder from a stirring host machine to a pouring station. After the precast concrete is transported to the pouring station, the storage bin dumping actuating mechanism supplies a power to turn over the cylinder and unload the precast concrete. Compared with the prior art, the precast concrete carrier vehicle provided by the invention has the advantages that the structure and the operation are simple, the use is safe and reliable, the automatic operation of transporting the precast concrete is realized, the labor intensity is relieved, and the labor cost is lowered.
