The invention relates to a self-propelled tractable dolly car. The self-propelled tractable dolly car comprises a car frame, two driving devices, a steering device, a hydraulic unit, a power control device and a traction linkage mechanism. The car frame is divided into three areas which are the front area, the middle area and the rear area respectively. A steering axle is transversely installed below the front area of the car frame through the steering device via a center swinging hinge. Two steering tires are installed on the left and right side of the steering axle respectively through hydraulic steering mechanisms. The hydraulic unit is installed in the rear area of the car frame, the power control device is installed in the middle area of the car frame, and a rear traction mechanism is installed on the middle rear side of the rear area of the car frame. Four hydraulic supports are installed at the lower end of the car frame. The self-propelled tractable dolly car has the advantages of being ingenious in design, reasonable and compact in structure, convenient to operate, small in occupied space and powerful in function. The self-propelled tractable dolly car can move freely by means of the driving units and can operate within a small space. As the traction mechanisms are arranged front and back, the self-propelled tractable dolly car can be used for traction; the hydraulic supports are arranged on the periphery of the car frame and can lift the car stably, and stable operation is ensured; a rope tightener is installed at the lower end of the car frame, so that it is guaranteed that the car is firmly fixed during air transportation; the self-propelled tractable dolly car is safe and reliable when used and meets different requirements.
