The invention discloses short-distance transportation equipment applied to an excavator. The short-distance transportation equipment comprises a shaft rod, two tires, a shell and a pair of supporting plates, wherein the two tires are rotationally connected with the two sides of the shaft rod respectively, the shell is connected with the shaft rod to bear the weight of the excavator, and the supporting plates are fixed to the bottoms of a pair of second panels respectively so as to support bottom wheels of the excavator. A hole is formed in the circle center of each tire so that the shaft rod can penetrate the holes to be rotationally connected with the tires. A bearing is arranged between the shaft rod and the inner wall of each hole. An oil guiding groove is formed in the surface of the shaft rod in the axial direction. Each supporting plate is provided with a bottom face supporting layer, a top face anti-skid layer and a cushioned layer which is arranged between the bottom face supporting layer and the top face anti-skid layer and made of elastic materials. The short-distance transportation equipment is simple in structure and suitable for the heavy-duty excavator and bumpy roads, facilitates shifting of the excavator and greatly saves the cost of a trailer.
