The disclosed subject matter is directed to a hydraulic steering shear-fork aerial work platform that comprises a running chassis and a lifting device. The running chassis includes a chassis body and a running device that comprises a left wheel carrier, a right wheel carrier, a linkage frame, and a steering oil cylinder. The left wheel carrier and the right wheel carrier are rotatably installed on the chassis body through wheel carrier shafts. The two ends of the linkage frame are respectively hinged to the left wheel carrier and the right wheel carrier. One end of the steering oil cylinder is installed at one end of the linkage frame, and the other end of the steering oil cylinder is fixedly connected with the wheel carrier shaft through an installing plate.
