Tank Semi-Trailer

Tank semi-trailers take tanks as the main bearing structure to transport liquids, powder materials, bulk cement and other goods, including liquid tank, powder tank, gas tank, particle tank, mixer tank and water sprinkler models.

The tanks are elaborately manufactured via 3D modeling and matched with dedicated reliable chassis. They enable efficient loading and unloading, protect cargo, improve transportation safety, and cut packaging and labor costs.

Classified by transported materials: liquid tanks carry fuel, chemical liquids and drinking water; powder tanks transport cement and stone powder; gas tanks store industrial gas; particle tanks deliver grain and plastic pellets.

By internal pressure, they are divided into low-pressure, medium-pressure and high-pressure tanks for different materials such as water, fuel, asphalt and caustic substances.

The load on semi-trailers is fully self-supporting. The tractor only connects via couplings and provides driving power without bearing any cargo weight. Combinations of one or more semi-trailers are widely used for long-distance transportation. A semi-trailer consists of frame, traction, steering, suspension, braking and other systems.
Frames fall into three types: straight beam, stepped beam and concave beam. Straight-beam frames feature flat floors, simple manufacturing processes and excellent trafficability. Heavy-duty semi-trailers adopt integrated box-welded frames with strong bending and torsion resistance for solid structure. Equipped with rotary suspension mechanisms, they realize all-wheel steering. The low-profile yet high-strength frame suits heavy and oversized cargo, enabling easy loading and unloading as well as stable operation.
