The invention relates to a hydraulic traveling wheel jacking system of a basketball stand. The jacking system comprises a chassis and an oil cylinder of the basketball stand, and a pair of front wheels and a pair of rear wheels which are arranged under the chassis and respectively on a front wheel seat and a rear wheel seat. The system is characterized in that: the chassis is fixedly connected with a front connecting plate, a rear connecting plate, a support and a base; the front wheel seat is articulated with the front connecting plate; the front wheel seat is articulated with the base by a connecting rod, and the connecting rod is formed by articulating a connecting rod 1 and a connecting rod 2; the oil cylinder is articulated between a joint of the connecting 1 and the connecting 2 andthe support; the rear wheel seat is connected with a hinge plate; the hinge plate is articulated with the rear connecting plate, and the hinge plate is articulated with the front wheel seat by the front connecting rod and the rear connecting rod. An operating mode of a piston rod in the oil cylinder helps controls the chassis of the basketball stand to lift or lower by the hydraulic device of theoil cylinder, which facilitates movement of the basketball stand and has simple structure, high stability, and high safety and reliability for use.
