The 12-meter three-axle container skeleton trailer is a professional port and logistics-dedicated chassis trailer developed by Prime Mover Industries, specially optimized for standard 40ft full-size shipping containers and dual 20ft container combined transportation. Different from heavy flatbed trailers, this skeleton-style hollow frame design abandons redundant deck structures, achieving ultra-light tare weight while retaining rigid structural strength. It focuses on container dedicated transportation scenarios, featuring low fuel consumption, fast loading and unloading, flexible maneuverability and strict road compliance. It is the most cost-effective mainstream model for port depot turnover, inland container logistics and cross-border container transportation, widely adapted to global terminal, highway and urban logistics transportation standards.


Adopts optimized hollow skeleton beam layout and streamlined structural design, greatly reducing self-weight compared with traditional flatbed trailers. The lighter body effectively increases the effective cargo load under limited total vehicle weight, helping fleets maximize single-trip container loading capacity and obtain higher freight income without violating axle load regulations. It significantly reduces empty-load fuel consumption and tire loss, bringing long-term cost advantages for high-frequency container turnover operations.
Equipped with high-precision fixed container twist lock groups arranged strictly in accordance with ISO international container standard sizes. The lock positions perfectly match 40ft single container or 2×20ft combined container locking points. After container positioning and locking, no lateral sliding or longitudinal displacement will occur during high-speed driving, bumpy road transportation and emergency braking. The professional anti-offset limit structure fully ensures the safety of container and internal goods.
The 12-meter standard body length features flexible turning radius and excellent site adaptability, solving the problem of bulky and inflexible oversized trailers. It is suitable for narrow terminal passages, dense depot stacking areas and urban logistics distribution roads, realizing efficient docking with container gantry cranes and yard cranes, greatly improving container loading and unloading turnover efficiency.
The main frame adopts Q345B high-tensile steel integral bending and full submerged arc welding process, with overall uniform stress and strong torsion resistance. Even under long-term high-frequency container loading and unloading and highway vibration, the frame is not easy to deform or crack. Matched with professional shot blasting and multi-layer anti-corrosion paint process, it resists coastal salt fog, humid and dusty environments, ensuring long-term stable operation in port and open-air yard scenarios.
All axles, brake systems, electrical components and pneumatic parts adopt mainstream universal standard accessories in the global market, with wide compatibility and easy replacement. The simplified skeleton structure has fewer vulnerable parts, no easy-damaged flat deck components, lower daily maintenance difficulty and shorter downtime, effectively improving fleet operation rate.

Ideal for high-frequency container transportation inside ports, terminals and freight yards. The lightweight body improves driving flexibility, adapts to frequent craning and handling operations, and efficiently matches terminal container loading and unloading rhythm to improve overall port logistics efficiency.
Suitable for door-to-door container transportation between ports, inland container depots and customer factories. The standard three-axle configuration fully complies with highway weight limit standards in Europe, Africa, Middle East and Southeast Asia, avoiding overweight fines and ensuring smooth cross-border passage.
The compact 12-meter body has flexible passing performance, adapting to urban road restrictions and narrow factory access roads. It is widely used for container distribution of foreign trade factories, cross-border e-commerce warehouses and industrial park goods turnover.
For fleet rotation operations of alternating empty and full containers, the lightweight skeleton design greatly reduces empty return fuel consumption and tire wear. Optional lift axle further reduces operation costs during empty-load driving, bringing significant economic benefits for long-term container leasing and transportation fleets.
Focus on checking the flexibility and locking firmness of all twist locks to ensure no looseness or failure during container transportation; inspect frame welding seams and main beam for deformation or cracks; check tire pressure and wear status of each axle to ensure consistent stress; test brake sensitivity and ABS system operation; drain water from air storage tank to prevent pipeline blockage.
Do not overload beyond the rated payload to avoid frame torsion deformation; ensure the container is completely locked in place before driving to prevent cargo displacement; avoid violent lifting and collision during container loading and unloading to protect twist locks and frame structure; long-term idle storage requires chassis anti-rust protection and tire pressure maintenance.
Integrated skeleton frame and main bearing structure: 60-month/300,000km long-term warranty; three axles and suspension core components: 24-month warranty; pneumatic brake system and electrical parts: 12-month warranty. Strict factory quality control ensures stable product performance for long-term container high-frequency operation.
Multilingual after-sales team provides remote video guidance and fault diagnosis services all year round, quickly solving common problems such as twist lock failure, brake system failure and axle abnormal wear, minimizing fleet downtime.
All matching accessories of the skeleton trailer are global universal standard parts, with sufficient overseas warehouse inventory. Original factory spare parts can be delivered quickly, realizing low-cost and fast maintenance without long waiting cycles.
