The semi-trailer container is a heavy logistics equipment specifically designed for the transportation of standardized containers. It is primarily used for the long-distance transfer and short-distance distribution of various standard and non-standard containers, such as 20ft, 40ft, and 45ft. It serves as a central support for modern port logistics, cross-border transportation, and freight on major routes. This model is characterized by "container-adapted specifications, efficiency and convenience, as well as safety and stability." Thanks to a high-strength chassis structure and a special locking mechanism, it enables rapid loading and secure anchoring of containers, adapting to various transportation scenarios. It is widely used in the fields of container logistics transportation, refrigerated transportation, compliant hazardous materials transportation (customized model), and multimodal transportation, both domestically and internationally.
