40ft Container Chassis Semi-Trailer (also called a 40-foot chassis or skeleton semi trailer) is a specialized trailer designed to transport standard 20-foot and 40-foot shipping containers.
Lightweight Design
Unlike flatbed or box trailers, the skeletal trailer removes unnecessary structures, making it lighter (typically around 5-6 tons). This increases cargo capacity and reduces fuel consumption.
High-Strength Frame
Built with high-strength steel or alloy steel welding, the frame offers excellent torsion resistance, handling both the concentrated load of containers and long-distance road vibrations.
Quick Loading & Unloading
Equipped with ISO-standard twist locks that securely fasten to container corner castings—no extra strapping needed. Loading and securing takes just 5-10 minutes.
Low Center of Gravity
The skeletal design positions the container flush against the frame, lowering the trailer’s center of gravity for better stability—especially at highway speeds.
