Referring to fig. 1, the air transportation system of the present disclosure includes a transportation rail 1 and an air transportation vehicle 2. The air vehicle 2 is configured to travel along the transportation rail 1 to transport the target cargo from the current position to the target position.
It should be noted that the terms "horizontal and vertical" used herein in describing the air transportation vehicle are set based on the moving direction of the clamp, and the direction in which the clamp is lifted by the lifting webbing is a vertical direction, and it can also be understood that the gravity direction of the lifted target cargo is a vertical direction, and correspondingly, the direction perpendicular to the vertical direction is a horizontal direction.

When the motor 21 is started, its armature shaft drives the driving pulley 22 to rotate, and the driving pulley 22 drives the driven pulley 23 to rotate synchronously through the synchronous belt 24.
The lifting mesh belt 3 is wound on the driven pulley 23, and one end part of the lifting mesh belt is a fixed end which is fixed on the chassis 20 or the driving pulley 23, and the other end part of the lifting mesh belt is a free end on which a mechanism of a clamp and a lifting hook which can lift the goods can be arranged.
