The 40FT skeleton semi trailer is a dedicated intermodal transport chassis tailored for standard 40-foot ISO shipping containers, serving global ports, container yards, cross-border logistics and highway freight transportation. Adopting a hollow frame structural design without a solid cargo floor, this trailer features ultra-light self-weight compared with flatbed trailers, effectively improving effective load capacity and reducing fuel costs for long-distance container transportation.

Constructed from high-strength manganese steel, the trailer’s integrated main beam is processed through integral bending and full penetration welding technology. The reinforced cross beams and stress-bearing points greatly enhance torsion resistance and structural stability, enabling long-term stable operation under heavy loads and adapting to complex road conditions and frequent container loading and unloading work.

This container skeleton trailer is fitted with precision positioned standard twist locks, which can firmly fix 40-foot standard containers to prevent shaking, sliding and tilting during high-speed driving and bumpy road transit. It supports multiple axle configurations including 3-axle and 4-axle to comply with different national highway axle load limit standards.

Equipped with heavy-duty axles, durable suspension system and complete air brake device, the trailer ensures sensitive braking response and safe driving performance. Standard landing gear, heavy-load kingpin, anti-collision protection, reflective warning strips and full LED lighting meet international road safety regulations. Featuring simple structure, low maintenance cost and high transportation efficiency, it is the mainstream reliable equipment for modern container intermodal logistics.
