Semi-trailers such as box trucks, tankers, flatbed trucks, and container trailers have always been important tools for land transportation, but they are also known as "fuel guzzlers". An empty heavy-duty steel semi-trailer typically consumes as much as 25 liters of fuel per 100 kilometers. The solution is simple: "Making the vehicle lighter can reduce fuel consumption."
As far as I know, aluminum alloy materials are much lighter than steel, and replacing steel semi-trailers with aluminum alloy ones has become a key way to achieve lightweight design. Under the same performance conditions, aluminum alloy semi-trailers are 35% to 40% lighter than steel semi-trailers.
Reports show that in developed countries such as Europe and the United States, the penetration rate of aluminum semi-trailers has exceeded 70%. All-aluminum vehicles can bring direct economic benefits to users: a single semi-trailer can carry an additional 3.4 tons of cargo. With a transportation cost of 0.5 yuan per ton-kilometer and an annual mileage of 200,000 kilometers, each vehicle can increase annual revenue by 340,000 yuan. During its service life, it can also save approximately 45,000 liters of fuel and reduce carbon dioxide emissions by 110 tons.
High costs and large one-time purchase investments are the main reasons for the current difficulty in promoting aluminum semi-trailers. Restricted by high aluminum prices and small production scales, the production cost of aluminum semi-trailers is more than twice that of steel semi-trailers.
In fact, the energy-saving performance of aluminum semi-trailers can fully offset the user's purchase cost in the long run. Chengda Trailer Factory specializes in manufacturing various lightweight trailers, which feature light weight, fatigue resistance, torsion resistance, deformation resistance, and safety, with a comprehensive improvement in load-carrying capacity.
