Why Choose Our 40-Foot Flatbed Semi-Trailer?

2.
Three pieces of 13-ton FUWA / BPW axles are optional: The standard configuration comes with three 13-ton axles, featuring more reasonable load distribution per axle, stable load-bearing performance and low failure rate.
3. Optimized wheelbase layout: 8000 × 1310 × 1310 mm wheelbase design, balancing heavy-load capacity and driving stability.
4. Wear-resistant, low-resistance tires: 12R22.5 heavy-duty tires, high strength, low rolling resistance, reducing the risk of tire blowouts and increased fuel consumption.
5. Optional suspension configurations: Mechanical suspension for durability and cost savings; air suspension for excellent shock absorption, suitable for transporting high-value goods.
6. JOST landing gear with anti-corrosion treatment: JOST heavy-duty support legs for safer loading and unloading; industrial-grade paint for effective rust and weather resistance.
