Tank semi-trailers are specialized transport vehicles with a tank as their core cargo structure. They are primarily used for specialized transportation of liquids (fuel, acids and alkalis), bulk materials (cement, fly ash), and bulk cement. Based on the transport medium, they can be categorized into four main types: liquid tankers, powder tankers, gas tankers, and granular tankers. Powder tankers are categorized by tank pressure into low-pressure, medium-pressure, and high-pressure types. Core technologies include innovative structures such as a fluidized bed unloading system and a dual-pipe air intake design, enabling high-speed unloading efficiency of 1.4 tons/minute and a residual ash rate of 0.2%. Typical models, such as the SDC9400GSN, utilize a gravity-driven pneumatic unloading system, boasting a capacity of 94 cubic meters and a 15% reduction in weight, while maintaining a 100% curb weight acceptance rate.
Structural Design: The tanks generally utilize a load-bearing single-V or double-V inward-inclined horizontal structure, utilizing fluidized bed technology to optimize material flow. The SDC9400GSN has a tank capacity of 94 cubic meters. The frame is made using manganese plate welding and automatic submerged arc welding technology, and the suspension adopts a steel plate stamping rigid structure. The wheelbase is designed to be 8750×1310×1310mm, and it is equipped with 12 tires to ensure load-bearing performance. Some models use an integrated molding process, and key welds are X-ray inspected, and the vehicle quality qualification rate remains 100%.
