Container Semi-Trailer
The CNFORCE Container Semi Trailer (Skeleton Trailer) is an intermodal chassis engineered for the efficient transport of 20ft, 40ft, and 45ft ISO shipping containers. Featuring straight-beam or gooseneck configurations fabricated from high-tensile Q345B/Q460C steel, this skeletal trailer provides a lightweight structure with high payload capacity. It is designed for port drayage, rail transshipment, transit stations, and long-haul highway logistics matching major tractor truck brands.

Key Features and Applications
Lightweight High-Tensile Skeletal Chassis
Fabricated from Q345B/Q460C high-tensile steel using automated submerged arc welding, the main I-beam chassis eliminates unnecessary deck weight while delivering the torsional stiffness required to resist sagging and bending under full container payloads.
Flexible Multi-Container Lock Configurations
Fitted with heavy-duty ISO twist locks configurable in 4, 8, or 12 sets. This allows the chassis to secure a single 40ft container, two 20ft containers, or one centered 20ft heavy container for balanced axle loading.
Proven Axle and Suspension Combinations
Configurable with 2-axle, 3-axle (tri-axle), or multi-axle setups using FUWA or BPW axles. Suspensions can be specified as heavy-duty mechanical leaf springs for rugged routes or air suspension for smooth highway drayage and reduced tire wear.
Reliable Braking and Running Safety
Equipped with a dual-line pneumatic braking system featuring WABCO emergency relay valves, T30/30 spring brake chambers, and a 24V electrical system with sealed LED lighting conforming to standard international road regulations.
Primary Logistics Applications
-
Port and Terminal Drayage: Rapid transfer of laden and empty containers between vessel berths and storage yards.
-
Intermodal Rail Hubs: Transshipment of ocean containers between railway flatcars and distribution warehouses.
-
Highway Logistics Corridors: Direct warehouse-to-warehouse container hauling across regional transit routes.

Dimensions and Operating Range
Overall chassis length for the standard 40ft model measures 12,400 mm to 12,500 mm with an overall width of 2,500 mm. Frame height ranges from 1,530 mm to 1,550 mm depending on tire and suspension selection. The skeletal layout facilitates top-loading and side-loading by reach stackers, gantry cranes, and container straddle carriers, enabling direct warehouse-to-warehouse transfers without opening or unboxing the cargo.
Supplier Support
We provide technical documentation, configuration consulting, and export procurement support for CNFORCE container semi trailers. Our engineering team assists with tractor truck fifth-wheel matching, kingpin sizing, and axle load distribution to comply with regional highway standards. For maritime delivery, trailers are shipped via RORO vessels, bulk cargo ships, or nested in container flat racks. Chassis frames undergo shot blasting, anti-corrosion primer application, and marine-grade protective wax spraying to resist saltwater atmospheric corrosion during ocean transit. Replacement twist locks, landing gear parts, and brake components are accessible through our export supply network.
Frequently Asked Questions
What container sizes can this skeleton semi trailer transport?
The skeleton trailer is engineered to haul standard ISO shipping containers, including 20ft, 40ft, and 45ft dry freight containers, high-cube containers, and reefer units.
What is the advantage of a skeletal chassis over a flatbed trailer?
A skeletal chassis eliminates the steel deck plate, resulting in a lower tare weight (around 5,200 kg to 6,000 kg). This weight reduction allows fleets to maximize payload capacity per trip and improve tractor fuel economy when running without cargo.
Can the trailer be configured with an air suspension or lift axle?
Yes. Depending on operational requirements and local axle-load laws, the trailer can be equipped with air suspension on all axles or an air-lift system on the front axle to reduce tire wear during unladen transit.
How are the trailers secured and protected during ocean shipment?
Trailers are shipped via RORO or bulk vessels with comprehensive protective coatings, including shot-blasting, anti-corrosion primer, and marine wax spraying. For bulk shipping, trailers can be stacked and lashed securely to optimize freight volume and minimize shipping costs.
