[0002] The vehicle beam is a major body structure in heavy-duty vehicles and serves as the load-bearing component. Located in the middle of the vehicle body, it supports and suspends the main components. Vehicle beams are typically made of steel frames, possessing high strength and corrosion resistance, capable of withstanding large loads and shear forces. During production, the outer perimeter of the vehicle beam's components is welded using welding equipment. In this process, the beam frame is placed on a welding platform, and welders first weld the upper and sides of the frame. When welding the lower side of the beam frame, it needs to be lifted and placed on a high platform using hoisting equipment. This method is not only complex but also time-consuming, thus affecting the overall welding efficiency of the vehicle beam frame. Utility Model Content
