The utility model belongs to the field of automobile manufacturing and refitting, and particularly relates to a full-hydraulic steering device of an unmanned wide-body mining dump truck, which is characterized in that a hydraulic oil tank, a steering pump, a priority valve, a steering gear, a hydraulic steering system and an unmanned control system are respectively arranged on the truck, and the unmanned control system is used for collecting road condition information. When the unmanned control system sends a steering instruction, the steering pump conveys hydraulic oil to the priority valve, the priority valve provides proper flow to the steering gear, and then the hydraulic oil is distributed to the hydraulic steering device system through the steering gear. According to different steering instructions sent by the unmanned control system, hydraulic oil is conveyed to the tail ends of the hydraulic rods at different positions to achieve the steering process, the steering angle is controlled by the hydraulic
