[0003] [Patent Document 1] Japanese Patent Application Publication No. 2017-200807 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in conventional multi-purpose vehicles, when loading and unloading cargo between the loading platform and shelves or the like that are higher than the loading platform, doing the work manually puts a heavy physical strain on the worker, and using a forklift has the inconvenience of requiring space for the forklift to move.

[0005] In view of the above problems, the present invention aims to provide a multipurpose vehicle that allows easy loading and unloading of luggage and the like on the loading platform and on shelves or the like that are located higher than the loading platform. [Means for solving the problem]

[0006] The multipurpose vehicle of the present invention includes a running body, a loading platform provided at the rear of the running body, and a lifting mechanism that raises and lowers the loading platform relative to the running body while maintaining the platform in a horizontal state. The loading platform is configured to be manually adjustable in height, and the loading platform includes a bottom surface and: When the loading platform is lowered, in the height direction from the lateral edge of the bottom portion , to a height lower than the top of the rope frame surrounding the seat and a side wall portion extending from the bottom portion to prevent a worker from falling, and the side wall portion is configured to be openable and closable by rotating around an axis extending in the front-to-rear direction.

[0007] According to this invention, loading and unloading of cargo can be performed with the height of the loading platform adjusted to a shelf or the like that is higher than the loading platform. In this case, since there is no need to move the cargo in the vertical direction, even if loading and unloading work is done manually without using a fall lift or the like, it is possible to perform the work with less physical strain on the worker.

[0008]

[0009] In addition, with this configuration, the side wall portion can prevent workers working on the loading platform from falling, and by opening the side wall portion, it is possible to facilitate loading and unloading of luggage, etc.

[0010] In the present invention, it is preferable that an operating tool for performing the manual operation is provided, and that the operating tool is provided on the loading platform.

[0011] With this configuration, the worker can change the height of the loading platform while standing on it, and can easily match the height of the loading platform with the height of the shelves or the like where cargo and other items are loaded and unloaded.

[0012] In the present invention, it is preferable that the lifting mechanism is driven to move up and down by electricity.

[0013] According to this configuration, the lifting mechanism can be configured using a commonly used electric drive device.

[0014] In the present invention, it is preferable that the lifting mechanism is hydraulically driven to move up and down.

[0015] According to this configuration, the lifting mechanism can be configured using a commonly used hydraulic drive device. [Brief explanation of the drawings]
