Electric flatbed is a transportation tool used for pulling goods powered by an electric battery and an electric motor; Electricity, as an important energy source that is environmentally friendly, clean, and has a high conversion rate, is used to drive the upgrading of transportation vehicles, promote the low-carbon development of the transportation industry, reduce transportation costs, save energy, and protect the environment. It is one of the important topics studied by countries around the world. After decades of development, it has been applied in many fields such as urban public transportation vehicles, electric transportation vehicles for factories and mines, electric urban sanitation and cleaning vehicles, engineering, tunnel, and subway construction special vehicles. Electric flatbed trucks have the advantages of strong applicability, mobile recording, simple maintenance, convenient maintenance, and low price. Electric flat cars are widely used in short distance transportation fields such as factory areas, mining areas, and environmental sanitation.

Electric flat cars are generally used in harsh environments, requiring durable motors and batteries, as well as high requirements for frame materials and welding processes. The thickness of the frame pipes is 2.5 or more, and plasma shielded welding is used for welding. The welding density is high, the tensile strength of the weld seam is high, and it is not easy to break. Can adapt to the requirements of the factory operating environment.
