The invention provides a hydraulic suspension heavy-load transportation vehicle. The hydraulic suspension heavy-load transportation vehicle comprises a vehicle body, an axle and wheels; a slewing bearing is arranged on the vehicle body; the slewing bearing comprises an inner ring and an outer ring; the inner ring and the outer ring are capable of rotating relatively; the outer ring is horizontally fixed on the vehicle body; a supporting seat is fixed in the inner ring; the vehicle further comprises a steering system; the steering system comprises a front wheel group and a rear wheel group; the front wheel group and the rear wheel group are driven by a steering hydraulic cylinder, respectively; the steering hydraulic cylinder is horizontally mounted on the vehicle body and hinged to a stirring crank arm; the stirring crank arm is fixedly connected to the top surface of the supporting seat; the supporting seat rotates along with the slewing bearing so as to drive the wheels to rotate; for steering, the wheels of the front wheel group all are deflected in the same direction, while the wheels of the rear wheel group all are deflected in other direction; the wheels of the vehicle run in the same moving trajectory, and therefore, the all-wheel steering of the vehicle is realized. The hydraulic suspension heavy-load transportation vehicle is capable of meeting the requirements of large logistics transportation due to a small turning radius and flexible turning; meanwhile, the cost is also reduced and the production efficiency is improved.
