40ft Tri-Axle Skeleton Semi Trailer Detailed Description
Optimized Chassis for Maximum Payload
Our 40ft skeletal trailer features an advanced frame design that reduces tare weight without sacrificing strength.
This improves fuel efficiency during long-distance hauls. The main beam is crafted from Q345B high-strength steel, providing excellent resistance to bending and heavy impact during crane loading.
Precision Components & Port Readiness
Equipped with three heavy-duty FUWA axles and a robust mechanical suspension, the trailer ensures balanced weight distribution.
The 12 high-quality twist locks allow for flexible container configurations, ensuring cargo stays firmly in place. To withstand salty port air, the chassis undergoes full sandblasting and is finished with a multi-layer anti-corrosion coating.
