Introduction
The 40-foot container chassis semi-trailer is made of high-strength steel, serving as an efficient transfer equipment for ports and multimodal transportation scenarios.
Details
Specifically designed for 40-foot standard containers, it achieves "efficient adaptation + safe transportation".
The frame dimensions fully match 40-foot standard containers, with quick fixation via locking devices-no additional modification required, ensuring high loading and unloading efficiency.
The rational layout of chassis crossbeams and locking devices firmly secures containers, preventing displacement during transportation, ensuring safety and stability, and adapting to long-distance trunk transportation scenarios.

Applications
In ports and terminals, it serves as the hub for container land transfer, adapting to narrow yard passages and frequent loading/unloading needs, significantly improving terminal operation efficiency.
In multimodal transportation, it plays a "link" role, seamlessly connecting sea, railway, and road transportation. Containers received from ports can be directly transferred to inland logistics, making it a core tool for cross-border trade and domestic long-distance logistics.
In the field of professional cargo transportation, its adaptability is extremely strong: it can carry containers of piece goods such as electronic products, home appliances, and daily necessities; it can also transport heavy building materials like construction steel and cement prefabricated parts through special containers; it can even be customized with fixing schemes to adapt to special goods such as large mechanical equipment and wind power accessories, meeting the needs of multiple industries including industry, agriculture, and infrastructure.
In addition, it is widely used in logistics parks and warehousing centers, becoming a key support for the efficient operation of modern logistics.
