Technical Field

[0001] This utility model relates to the field of aluminum alloy flatbed truck technology, and in particular to a lightweight welded all-aluminum flatbed truck. Background Technology

[0002] In Europe and America, aluminum alloy flatbed trucks have become a common product, with some even used in mini electric four-wheeled vehicles. To meet the demands of overseas markets, a new all-aluminum flatbed truck specifically designed for international markets has been developed based on existing technology. Under the national policy of energy conservation and emission reduction, lightweight aluminum alloy flatbed trucks significantly improve transportation efficiency due to their substantial weight reduction advantages. Aluminum alloy has a density only slightly more than one-third that of steel and is recyclable, low-carbon, and environmentally friendly.

[0003] Flatbed trucks are a common type of transport vehicle, with a flat body. They mainly consist of a frame, flatbed, axles, and handrails or levers; they are available in human-powered and electric-powered types. Human-powered flatbed trucks are moved by pushing or pulling the handles to make the wheels roll, thus transporting goods.

[0004] Flatbed trucks are heavy due to the large weight of steel, which increases the overall weight of the vehicle. Furthermore, steel is not recyclable and is highly corrosive, making it susceptible to damage in harsh transportation environments and requiring frequent maintenance or replacement, further increasing operating costs. Therefore, a lightweight welded all-aluminum flatbed truck is proposed to address these issues. Utility Model Content
