Container truck transportation generally has problems such as environmental pollution and transportation safety hazards.

[0003] The braking performance of the traction mechanism of traditional railway vehicles is difficult to meet the application requirements in the operating environment of large altitude difference between coal mines and coal transportation railway stations, large line slope and strong wind climate. Aerial rail transportation driven by linear motors can significantly improve the climbing performance of vehicles and is not restricted by terrain. It is a suitable way to solve the problem of coal transportation under line conditions such as large slope and large drop.

[0078] The shapes, sizes, ratios, angles, and numbers disclosed for describing various aspects of the present specification and claims are merely examples, and therefore, the present specification and claims are not limited to the details shown. In the following description, when the detailed description of the related known functions or configurations is determined to be unnecessarily obscuring the focus of the present specification and claims, the detailed description will be omitted.

[0079] In the case of using “including”, “having” and “comprising” described in the present specification, unless otherwise used, there may also be another part or other parts, and the terms used may generally be in the singular but may also represent the plural form.

[0080] It should be noted that although the terms "first", "second", "top", "bottom", "one side", "the other side", "one end", "the other end", etc. may appear and be used in this specification to describe various components, these components and parts should not be limited by these terms. These terms are only used to distinguish one component and part from another component and part. For example, without departing from the scope of this specification, the first component can be called the second component, and similarly, the second component can be called the first component. The components at the top and bottom can also be swapped or converted with each other under certain circumstances; the components at one end and the other end can have the same or different performances.

[0081] In addition, when constituting a component, although there is no clear description thereof, it can be understood that a certain error area is necessarily included. When describing a positional relationship, for example, when the positional sequence is described as "on ...", "above ...", "below ..." and "next", unless words or terms such as "just" or "directly" are used, the situation where they are not in contact or in contact can also be included. If it is mentioned that the first element is "on" the second element, it does not mean that the first element must be above the second element in the figure. The upper and lower parts of the component will change according to the change of the angle of observation and orientation. Therefore, in the accompanying drawings or in the actual construction, if it is involved that the first element is "on" the second element, the situation where the first element is "below" the second element and the situation where the first element is "above" the second element can be included. When describing a temporal relationship, unless "just" or "directly" is used, when describing "after", "subsequently", "subsequently" and "before", the situation where the steps are not continuous can be included.

[0082] The features of various embodiments of the present invention may be combined or spliced ​​with each other in part or in whole, and may be performed in various different configurations as those skilled in the art may fully understand. The embodiments of the present invention may be performed independently of each other, or may be performed together through interdependent relationships.

[0083] The above are only specific embodiments of the present invention. It should be pointed out that any changes or substitutions that can be easily thought of by any technician familiar with the field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention. The rest not described in detail are prior arts.
