Description
Technical Field
[0001] The utility model belongs to the field of slope climbing equipment, in particular to automatic cargo climbing equipment. Background Art
[0002] With the rapid development of science and technology, the ways and methods of transporting goods have gradually increased. Water and rail transportation have developed together, and the transportation volume has also increased. In terms of rail transportation, the National Railway Group has made every effort to ensure the transportation of key materials such as electric coal, grain, and fertilizers, increase the transportation of collection ports and "road to rail", and continuously improve the quality of freight services. The national railway completed 3.91 billion tons of cargo shipments throughout the year, setting a new historical high. In ordinary life, people use family cars and box trucks for short-distance transportation to transport goods. In addition, when people need to transport goods to high places or cannot use vehicles for transportation, the ability to transport goods is significantly reduced. For example: when individuals face high floors, they are alone and weak, and cannot complete the transportation of all goods at one time, or it is difficult to independently complete the transportation of some large and precious objects. At the same time, considering that the elderly and young children cannot complete the short-distance transportation of goods in certain specific situations by themselves. Or in mountainous areas, construction sites and other rugged terrains, there is a lack of transportation devices that can be operated by one person, have strong cargo capacity, and adapt to various road environments, except for cars and human-powered wheelbarrows. This is the current lack of human-powered transportation of goods. Utility Model Content
