Technical Field

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

[0002] A logistics trolley, also known as a logistics trolley or cargo trolley, is a unit-type mobile container designed specifically for transporting and storing materials. It typically has four casters for easy pushing or pulling. It is widely used in large supermarket logistics distribution and for inter-process logistics in factories.
