3 Axle Skeleton Semi Trailer is a practical container transport solution designed for ports, logistics companies, freight operators, and intermodal transportation. With its open skeleton frame, the trailer provides a simple and strong platform for transporting standard shipping containers. Compared with a conventional flatbed semi trailer, a skeletal trailer removes the unnecessary deck structure and focuses on the main chassis, container locking system, suspension, axles, and running gear.
INTAI Factory manufactures Tri Axle Container Chassis Trailer for different container transportation requirements. The trailer can be configured for 20ft, 40ft, and other ISO container applications according to the customer’s transportation needs. In addition, the frame uses high-strength Q345B steel, while heavy-duty axles, reliable tires, mechanical suspension, and ISO container twist locks work together to provide stable performance for daily container hauling. As a result, the 3 Axle 40ft Skeletal Semi Trailer is especially suitable for regular 40ft container transportation between ports, terminals, warehouses, factories, and logistics centers.

The open-frame design keeps the trailer relatively lightweight while providing direct support for the container. For customers who mainly transport 40ft containers, the 3 Axle 40ft Skeleton Trailer offers a balanced combination of load capacity, structural strength, operating stability, and transportation efficiency. Typical 40ft skeletal trailer dimensions are around 12,400–12,500 mm in length and approximately 2,500 mm in width, although INTAI can adjust the dimensions according to local regulations and customer requirements. Industry configurations commonly use 13-ton or 16-ton axles, while the final payload depends on the trailer design, axle configuration, road regulations, and container weight.
INTAI Factory uses Q345B high-strength structural steel for the main frame of the 3 Axle Skeleton Semi Trailer. In particular, Q345B is widely used in heavy-duty trailer manufacturing because it provides a good balance between strength, weldability, durability, and manufacturing cost. Meanwhile, the main beam commonly uses an I-section structure. Depending on the customer’s load requirements, the main beam height can be around 450–500 mm, with the plate thickness adjusted according to the engineering design. For example, some heavy-duty industry configurations use a 500 mm main beam with approximately 14 mm upper plates, 8 mm web plates, and 16 mm lower plates. However, INTAI can modify the structure according to the required load rating and operating conditions.
The three-axle configuration is an important feature of this skeleton trailer. 3 Axle Skeleton Trailer distributes the container load across multiple axle groups and provides stable handling for medium- and heavy-duty container transportation.
Common axle capacities include 13 tons or 16 tons per axle, depending on the target market and legal axle-load requirements. Customers can choose axle brands such as FUWA or BPW, or request other suitable brands according to their local service network and budget.
A typical tri-axle configuration offers several benefits:
INTAI can also provide different axle configurations for customers who require specific gross vehicle weight or axle-load ratings.
INTAI Factory focuses on the design and manufacturing of semi trailers for different transportation applications. For container logistics, INTAI provides customized Skeletal Semi Trailers based on container size, road conditions, axle-load regulations, transportation distance, and customer budget.
The factory can customize key components such as:
This customization allows overseas customers to order a trailer that matches their actual operating conditions, rather than purchasing a fixed configuration that may not fully suit their market. At the same time, INTAI pays close attention to welding quality, component assembly, frame alignment, braking performance, and final inspection to ensure reliable trailer performance. Furthermore, for export orders, INTAI can adjust the trailer configuration according to the destination country’s road regulations and transportation requirements.
With factory-based manufacturing and customization capabilities, INTAI can develop the trailer configuration according to your transportation needs. Whether you need a standard 40ft container chassis, a multi-size container skeleton trailer, or a reinforced heavy-duty version, INTAI can provide a suitable solution for your fleet.
