Tri Axle 40Ft Skeletal Trailer

This 40Ft Skeletal Trailer is a heavy-duty container transport semi-trailer engineered for the efficient movement of 40ft ISO containers across ports, shipping terminals, logistics yards, and long-distance freight operations. Designed specifically for fleet operators, freight companies, container logistics providers, and transportation contractors, it delivers reliable operational performance under demanding working conditions.
Also referred to as a 40ft container chassis trailer or skeleton semi-trailer, it is custom-built to transport ISO shipping containers without a traditional cargo platform. The open-frame design significantly reduces empty trailer weight while maintaining high structural strength, enabling operators to improve fuel efficiency and maximize payload capacity. The chassis connects directly to containers via heavy-duty twist locks, facilitating fast loading and unloading between trucks, ships, railway terminals, and container yards.
Main Applications
International container transportation
Port-to-terminal container delivery
Railway container transfer
Freight forwarding operations
Shipping company fleet transportation
Logistics warehouse distribution

Heavy-Duty Three-Axle Structure for Load Distribution
The tri-axle configuration distributes container weight evenly across the chassis, reducing stress concentration on individual components. Compared to a 2-axle container chassis, this 3-axle design provides optimized weight distribution, improved driving stability, higher loading capacity, reduced axle and tire pressure, and superior performance for long-distance transport. Standard configurations utilize three 13-ton or 16-ton axles sourced from reliable industry suppliers such as FUWA or BPW.
 

Reinforced Skeletal Frame for Heavy Container Loads
The chassis utilizes high-strength steel construction featuring reinforced longitudinal beams and cross members. The optimized skeletal design delivers strong resistance against bending and twisting, ensures reliable performance under repeated loading cycles, maintains a reduced empty trailer weight, and allows for easier maintenance compared to enclosed trailer structures. The main beams are manufactured using Q345 high-strength steel or equivalent materials based on operational requirements.
 

ISO Standard Twist Lock System for Secure Fixing
The trailer is equipped with ISO-compatible twist locks to firmly secure containers to the chassis during transit. This system prevents container movement during transportation, enhances road safety, and supports fast loading and unloading operations compatible with standard 20ft and 40ft containers. Optional configurations can be customized based on specific container types and operating environments.
