The invention discloses an automatic gradient adjustment portal crane and relates to the technical field of cranes. The automatic gradient adjustment portal crane comprises a supporting device, a sliding device, a moving device and a power device. The left end of the front surface of a steel frame I is fixedly connected with a spring layer I. The adjacent surfaces of the steel frame I and a steelframe II are provided with sliding grooves. The upper surface of the steel frame I is provided with a rolling groove. Rolling wheels I are attached to the interior of the rolling groove. The upper ends of the rolling wheels I are movably sleeved with a trolley frame. The lower surface of the trolley frame is fixedly connected with a fixed block. The front and rear surfaces of the fixed block are fixedly connected with sliding bars. The upper surface of the trolley frame is fixedly connected with a fixed disk. A motor is started to drive an output shaft to rotate, the output shaft drives a gearIII to rotate, the gear III drives a gear II and a gear I to rotate, a steering column drives a gravity bar to move, and the gravity bar maintains the vertical state under the action of gravity. Whenthe automatic gradient adjustment portal crane is used for transferring an object, the object is not prone to inclination and toppling, and the operation safety of working staff is greatly guaranteed.
