Hydraulic steering shear-fork type aerial work platform

A hydraulic steering shear-fork type aerial work platform comprises a running chassis and a lifting device, wherein the running chassis comprises a chassis body and a running device, the running device comprises a left steering wheel, a right steering wheel, a left wheel carrier, a right wheel carrier, a linkage frame and a steering oil cylinder, and the left steering wheel and the right steering wheel are respectively installed on the left wheel carrier and the right wheel carrier, and the left wheel carrier and the right wheel carrier are rotatably installed on the chassis body through wheel carrier shafts;

• characterized in that the two ends of the linkage frame are respectively hinged to the left wheel carrier and the right wheel carrier;
• the linkage frame further comprises a steering oil cylinder installing portion for one end of the steering oil cylinder to be installed;
• the other end of the steering oil cylinder is fixedly connected with the wheel carrier shaft through an installing plate, so that the left steering wheel and the right steering wheel turn towards one side when the steering oil cylinder is controlled to extend, and the left steering wheel and the right steering wheel turn towards the other side when the steering oil cylinder is controlled to withdraw.
