The main vehicle + trailer double-box structure has a total volume of 130-145m³ (main vehicle 66m³ + trailer 64m³), which is equivalent to the compliant loading capacity of two 9.6-meter cargo trucks, making it particularly suitable for light bulk cargo transportation‌.
The total length of the cargo box is 17.1 meters (main vehicle 8.85 meters + trailer 8 meters), providing an additional 4 meters of effective cargo space compared to a 13-meter semi-trailer.

The main vehicle can load and unload cargo independently (volume 66 m³), and after separation, the trailer can quickly connect with other main vehicles, enabling a “one main vehicle, multiple trailers” drop-and-hook transportation mode.
The hydraulic system supports quick coupling, reducing the entire loading and unloading process time by 40% compared to traditional semi-trailers.

The central axle design positions the trailer axle at the center of gravity, with vertical loads affecting only 10% of the tractor unit. High-speed cornering stability is improved by 50% compared to full trailers.
Standard WABCO ABS + air suspension reduces braking distance by 30% compared to conventional semi-trailers.
