Meanwhile, the bearing capacity of the pedal is limited, 1 to 2 persons are allowed to take rescue equipment on the pedal, and the rescue efficiency is reduced to a certain extent.

Fig. 1 and 2 are schematic structural views of a second storage box in different working positions according to some embodiments of the article storage and taking structure of the present disclosure. Referring to fig. 1 and 2, in some embodiments, an article taking and placing structure includes a vehicle chassis 1, a first storage case 2, a second storage case 3, and a case driving device. The vehicle chassis 1 refers to a chassis structure which can drive the vehicle to move on a field or a road, and other structures (such as a boarding structure or an auxiliary structure and the like) of the vehicle can be supported and driven by a head of the vehicle chassis or other dragging equipment.

The first storage box 2 is fixedly disposed above the vehicle chassis 1, may have a frame structure, and is used for storage of articles. For the equipment fire engine, the storage device can be used for storing fire-fighting or rescue equipment. For other types of work vehicles, it may be used for storage of work tools or material as a work object. The first storage compartment 2 is arranged in a fixed manner relative to the vehicle chassis 1, has a high stability and can be used for storing a large number of or heavy objects.

A second storage compartment 3 is provided on at least one side of the first storage compartment 2, which can be used for storage of articles.
