Description

Technical Field

[0001] The utility model relates to the technical field of logistics turnover vehicles, in particular to a logistics turnover vehicle with a lifting structure. Background Art

[0002] With the rapid development of the logistics industry, turnover vehicles are often used in handling, loading and unloading. Logistics turnover vehicles can be used to transport goods or raw materials between warehouses, production lines, loading and unloading areas and other locations. They can carry items of various types and weights.

[0003] Existing logistics turnover vehicles are generally of a frame structure with four casters installed at the lower end for movement. When in use, materials are placed inside the frame. The structure is simple and the cost of use is low, but the height of the base cannot be adjusted up and down, and the height of the internal goods cannot be adjusted during loading and unloading. During the loading and unloading process, there will be a large height difference between the goods and the shelf, which makes loading and unloading more laborious. At the same time, the side doors generally adopt a latch structure, which generally cannot be automatically locked when closing the door, so the convenience of use is average. Utility Model Content
