である。As described above, according to this embodiment, the workbench 34 can be swung in the vertical and horizontal directions with respect to the deck 15 and can be moved in the horizontal direction.
The workable range is greatly expanded as compared with the case where the work is performed on the above 5, and it becomes possible to easily harvest fruits at a high position or at a position in the horizontal direction considerably away from the deck 15. In addition, in the above-mentioned embodiment, the workbench 34 is arranged at the rear part of the aerial work vehicle, but the front and rear direction of the vehicle body may be reversed to arrange the workbench 34 at the front part of the aerial work vehicle. The aerial work vehicle of the present invention can be used not only for harvesting fruits, but also for various works in orchards such as spraying fertilizer, caring for fruit trees and fruits, and for working in high places other than the orchards. Is also applicable.
