The invention relates to a two-wheel synchronous steering hydraulic system and a forklift. The two-wheel synchronous steering hydraulic system comprises a first steering wheel mechanism, a second steering wheel mechanism, a third steering wheel mechanism and an oil tank, wherein the first steering wheel mechanism and the second steering wheel mechanism are positioned at the front end of a forkliftframe; the third steering wheel mechanism is positioned at the rear end of the forklift frame; the first steering wheel mechanism is connected with a first oil cylinder; the second steering wheel mechanism is connected with a second oil cylinder; and the oil tank is connected with the first oil cylinder and the second oil cylinder through pressure valves. When a first piston in the first oil cylinder reaches a first position, the steering angle of the first steering wheel mechanism is controlled, and when a second piston in the second oil cylinder reaches a second position, the steering angleof the second steering wheel mechanism is controlled, so that the first steering wheel mechanism and the second steering wheel mechanism steer synchronously. The third steering wheel mechanism is connected with a third oil cylinder and independently steers through the third oil cylinder.
