The invention provides a multi-axis steerable telescopic flatbed transport vehicle, and relates to the field of special vehicles. The turning radius of a super-long cargo transport vehicle can be effectively decreased, and the vehicle passing capacity is improved. According to the technical scheme, the multi-axis steerable telescopic flatbed transport vehicle comprises a power gooseneck, a frame assembly and a wheel set steering assembly, and the frame assembly comprises a main longitudinal beam assembly and a telescopic beam assembly which can stretch out and draw back relative to the main longitudinal beam assembly; the wheel set steering assembly comprises five rotary discs corresponding to a rear five-axis axle, two parallel longitudinal pull rods are hinged to each two adjacent rotary discs, each rotary disc is provided with swing arms, transverse pull rods are hinged between swing arms and corresponding wheel steering arms at the two ends of the axle to drive a wheel to steer, and two oil cylinders used for driving the rotary disc to steer is connected to each rotary disc.
