The three-axle flatbed semi-trailer boasts core advantages such as lightweight construction, modular design, and efficient loading/unloading capabilities, making it widely used in the transportation of oversized cargo and fresh agricultural products. Below are its main features and applications:
1. Core Advantages

Utilizes composite material leaf springs (“plastic leaf springs”), with each spring weighing 65% less than traditional steel leaf springs. The vehicle's curb weight is as low as 4.8 tons (for the 13-meter model), enhancing cargo efficiency.
Standard equipment includes aluminum alloy wheels, landing legs, and honeycomb panel cargo boxes, further reducing weight.

The axles and upper structure are connected via bolts, enabling quick disassembly for convenient transportation and flexible modifications.
The columns can be disassembled independently, and the side panels can be optionally equipped with “quick-release hinges,” improving loading/unloading efficiency by 30%.

Low-profile straight beam design paired with BPW 10-ton-class axles, achieving a maximum load capacity of 34.7 tons.
Standard ABS (Kemi/Xihe brand), with some models equipped with disc brakes and hydraulic retarders for superior braking performance.
2. Main Applications

Suitable for non-standard cargo such as construction machinery and building materials, the 13-meter panel truck cargo box has a volume of 42.6 m³, supporting ultra-wide (2.55 meters) transportation.

The grille-style side panels facilitate ventilation, combined with a “wide-opening” design (side panels can be opened sideways or flipped down), suitable for quick loading and unloading of vegetables, fruits, and other fresh produce.

The exterior dimensions strictly comply with the GB1589-2016 standard, with a width of 2.55 meters, suitable for high-speed travel and areas with strict regulatory inspections.
