This 3-axle lowbed semi-trailer (lowboy) is purpose-built for heavy-duty transportation of construction machinery, large equipment, and over-dimensional cargo, combining high load capacity, stability, and durability.
Designed with a balanced multi-axle load distribution, the trailer delivers exceptional load-bearing capacity with a low center of gravity, ensuring stable handling and resistance to side tilting during turns and descents. Equipped with hydraulic ramps, it allows excavators, loaders, and other construction machinery to drive on and off independently, making loading and unloading operations efficient and hassle-free.

Constructed with Q345B/S700 high-strength steel, the trailer features a lightweight yet rigid frame that is resistant to torsion and impact, ideal for use on construction sites, mountain roads, and other challenging terrains. With a rated load capacity of 60-120 tons and a gross mass of 80,000kg, it balances strength and efficiency for compliant, high-payload transport.
Safety and reliability are enhanced by the WABCO EBS electronic brake system with ABS, ensuring stable braking performance and even tire wear for long service life. The trailer also features a 3.5-inch JOST kingpin, 12R22.5 tires, and a 24V 7-pin standard electrical interface, meeting international safety standards.
Key specifications include ultra-low deck height (600-700mm), overall dimensions of 16000×3000×1800mm, and a robust frame with 20mm top/bottom main beams and 12mm vertical plates.
