Container transportation means that the medium-sized and large-sized containers such as containers are used as carriers, and cargos are assembled into a containerization unit so as to carry out loading, unloading and carrying operations and finish transportation tasks by using large-sized loading and unloading machines and large-sized carrying vehicles in the modern circulation field, thereby better realizing a novel, efficient and beneficial transportation mode for transporting cargos from door to door. The container transportation has the advantages of high transportation efficiency, low transportation cost, convenient intermodal transportation, less cargo loss, door-to-door and the like, is a main mode of modern logistics and multi-mode intermodal transportation, and is widely adopted by all countries in the world.
Railway container vehicles are vehicles designed and manufactured specifically for the transportation of national and international standard containers. In the early stage of container transportation development, because of the small number of containers and the large number of types, the conventional transportation vehicles can be generally used for completing transportation tasks. With the rapid development of container transportation in the world, the large-scale and standardization of box types, the traditional vehicles can not meet the requirements of container transportation in the aspects of structure and performance, and special vehicles for containers have to be developed. At present, railways of all countries in the world develop a novel special container vehicle suitable for domestic and international intermodal transportation according to respective characteristics and requirements, and the novel special container vehicle is focused on the aspects of reducing energy consumption, improving speed, simplifying structure, lengthening vehicle body and the like. According to the length of the bottom plate of the special railway container vehicle, the special railway container vehicle can be divided into a special 40-foot container vehicle, a special 60-foot container vehicle and a special 80-foot container vehicle, and other special container vehicles with other lengths, wherein the special 40-foot container vehicle is provided with two TEU (terminal equipment unit) seats and can be used for loading 1 40-foot container or 2 20-foot containers; the 60-foot container special vehicle is provided with 3 TEU positions and can load 1 40-foot container and 1 20-foot container or 3 20-foot containers; the 80 foot container special vehicle has 4 TEU positions and is suitable for loading 2 40 foot containers.

In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly, e.g., as meaning fixedly connected, detachably connected, or integrally formed; may be mechanically coupled, may be electrically coupled or may be in communication with each other; either directly or indirectly through intervening media, such as through internal communication or through an interaction between two elements. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
In the present disclosure, unless expressly stated or limited otherwise, the first feature "on" or "under" the second feature may comprise direct contact between the first and second features, or may comprise contact between the first and second features not directly. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
