According to the present invention having such a configuration, the following effects can be expected. That is, in a vertical path where the station is located, by separating the support frame from the self-propelled dolly using the actuating device, the cargo storage case in the normal position can be lowered in a state separated from the self-propelled dolly, and the self-propelled A little before the lowering limit of the cart, the storage case is received from below by the receiver, and the amount of movement of the self-propelled cart to the lowering limit is increased, and the left and right pins are moved downward against the engagement piece. Then, by bringing the support frame closer to the self-propelled cart, the left and right pins can be removed from below the engagement piece, and then, by raising the self-propelled cart, the cargo storage case is lowered onto the platform. be able to. In addition, by performing the reverse operation, the receiver can load the cargo storage case on the platform onto the self-propelled cart. In this way, it is possible to quickly load and unload the transported objects at the station without requiring any human labor together with the transported object storage case, and without providing a special transfer device. Therefore, objects can be moved between the station and other locations together with this object storage case.
