[0002] At present, my country's coal transportation mainly includes road, rail and water transportation. Coal from coal mining plants is mostly transported by container trucks, which transport the crushed fine coal from coal mining areas to railway yards for long-distance transportation. Container truck transportation generally has problems such as environmental pollution and transportation safety hazards.

[0003] In the operating environment of large altitude difference between coal mines and coal transportation railway stations, steep line slope and strong wind climate, the traction and braking performance of traditional railway vehicles cannot meet the application requirements, and they can only be transported by a large number of container trucks, which leads to prominent problems such as congestion, pollution, efficiency and safety. The freight system using aerial rail transportation has received widespread attention in the market and has a good market prospect.

[0004] The existing suspended monorail freight system generally uses solid rubber wheels for the vehicle running system. Although solid rubber wheels have the advantage of strong load-bearing performance, they also have problems such as large rubber temperature rise over long distances and high operation and maintenance costs over the entire life cycle. They are mainly suitable for short-distance and low-speed applications. For large-volume, high-frequency, long-distance and other application scenarios, the use of solid rubber wheels has high maintenance costs and is difficult to be accepted by the market.

In addition, the technical solutions of the present invention are limited only by the scope of the claims.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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.

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.
