Description

Technical Field

[0001] The utility model relates to the technical field of carts, in particular to a self-unloading hand cart. Background Art

[0002] A handcart is a transport vehicle that is pushed and pulled by manpower. It is the ancestor of all vehicles. Although the material handling technology of handcarts continues to develop, handcarts are still used as an indispensable transport tool. Handcarts are widely used in production and life because they are low in cost, simple to maintain, easy to operate, light in weight, and can work in places where motor vehicles are inconvenient to use.

[0003] The handcarts in the prior art are not convenient for transporting long objects. For example, when transporting trees or pipes, the handles of the handcart hinder the handling of the objects, making it inconvenient to load and unload. During transportation, the staff needs to stand on one side of the handcart, which is inconvenient to control the handcart. In addition, the existing self-unloading handcarts can only unload goods to the front of the handcart. When unloading long goods, the handcart needs to move backwards at the same time, which inevitably causes wear and tear on the goods and the handcart, and is extremely inconvenient to operate. Therefore, a self-unloading handcart is proposed. Utility Model Content
