When performing balance adjustment, the controller outputs the corresponding extension and retraction amounts of the two counterweight electric push rods 15 based on the inclination angle feedback from the inclination sensor and the height information feedback from the height sensor 17, and controls the extension and retraction of the corresponding counterweight electric push rods 15 to balance the inclination angle caused by the uneven weight distribution of the components during the lifting process, thereby ensuring the balance and safety of the lifting process.
