Heavy semi-trailers specially designed for efficient logistics transportation adopt a gooseneck frame structure. The vehicle body is constructed with high-strength metal beams. Its evenly spaced warehouse fence grids are equipped with openable and closable fence doors, balancing ventilation performance and loading & unloading convenience.

　　Adopting high-strength steel and lightweight structures, the vehicle's curb weight is controlled at approximately 5 to 6 tons, effectively improving load-carrying efficiency and reducing fuel consumption.

　　Rated load capacity of 40 tons, wheelbase ranging from 12 to 13.5 meters, three-axle design equipped with 12 tires (mostly 12R22.5 specification), ensuring transportation stability and regulatory compliance.

　　Comes standard with ABS anti-lock braking system, heavy-duty disc brakes (2.5 times more wear-resistant) and anti-roll air suspension to reduce rollover risks, extending brake service life to 1.5 million kilometers.

　　Robot welding combined with electrophoretic coating and powder spraying processes, the coating weather resistance reaches 7 years;‌

　　The railings of the warehouse grid structure can be opened and closed, and the grid design balances ventilation and cargo spillage prevention. The anti-slip ladder and reflective markings at the rear improve operational safety.‌

　　Supports multi-color painting (red, yellow, etc.), cargo railing height adjustment and accessories such as tarpaulin frames, suitable for transportation scenarios of bulk goods, agricultural and sideline products and so on.
