are rotatably supported, and the rear end of the cover 10 is placed on the rear end of the frame 3 via both guide wheels 12, and the floor surface 3a of the frame 3 and the lower edge 10a of the cover 10 are connected to each other. In between is a palette P.
A gap 11 is formed which has a spacing slightly larger than the thickness of the upper plate P1, and into which the upper plate P1 is inserted and removed. The carrier body 1 is moved backward from the front of the pallet P, and the frame 3 is attached to the upper plate 5a of the pallet P.
When it enters the space below, both guide wheels 12 roll upward on the wrapper guide surface P2 of the pallet P and transfer from the floor surface 3a of the frame 3 to the pallet P (see Fig. 3A). , Furthermore, the guide rail P
The upper plate P1 of the pallet P is inserted into the gap 11, and the cover 10 moves backward on the pallet P together with the guide wheel 12. When the entire frame 3 enters the space below the upper plate P1 of the pallet P, the cover 10 is transferred onto the pallet P and the article B on the pallet P is covered with the cover 10. In this state, the frame 3 is moved upward, the pallet P is lifted from the ground position by the frame 3, and the carrier body 1 is driven to transport the object B together with the pallet P. Also, at the loading position of the transported object B, the frame 3 is moved to the lower position to lower the pallet P from the lifted position to the ground position, and then the carrier main body 1 is moved forward to move the frame 3 to the lower part of the upper plate P1. When the guide wheels 12 are moved forward from the space, the guide wheels 12 move to the guide rail P.

removed from above.

The shutter 14 is wound around the upper end of the rear end of the cover 10 so that it can be pulled out in order to open and close the opening at the rear end of the cover 10 when the object B is covered with the cover 10.

Next, the operation and effects of the embodiment having the above configuration will be explained.

In this example, a frame 3 extending horizontally behind the driver's cab 2 of the carrier body 1 extends into a space below an upper plate P1 formed horizontally at the upper end of a pallet P having a frontal shape. In the transportation vehicle A, which is installed so that it can be moved to a lower position where it can enter and an upper position where it can lift the pallet P, the frame 3 is located near the front end of the frame 3 in a space below the upper plate P1. When entering the section, the upper plate P
The front end of the cover 10 which is placed in parallel on the upper plate P1 and covers the transported object B on the same upper plate P1 is connected so as to be tiltable in the vertical direction. When entering the space, a cover 10 is placed on the rear end of the frame 3 to pivot the guide wheel 12 which is transferred from the top of the frame 3 to the top plate P1 and rolls on the top plate P1. The gap 11 in which the upper plate P1 is inserted and removed is the frame 3 at the rear end.
The guide ring 1 is formed between the guide ring 1 and the cover 10.
It is placed through 2.

Therefore, the cover 10 is automatically moved onto the pallet P when the frame 3 enters the space below the upper plate P1 of the pallet P or when the frame 3 escapes from the space below the upper plate P1. Transferred objects B are automatically covered or automatically removed from the pallet P, which simplifies and saves labor and makes the covering and removal operations for transported objects B easier and safer. It has the advantage of simplifying the mechanism for covering.

In particular, in this example, the cover 10 is stably supported on the frame 3 and the pallet P at both front and rear ends via the connecting pin 6 and the guide ring 12, so it can be applied to a long carrier body 1.

Furthermore, since the cover 10 is permanently placed on the frame 3 of the carrier body 1, it is possible to eliminate the problem that the work of loading and unloading the transported objects B onto the pallet P is obstructed by the cover permanently placed on the pallet P. With,
This has the effect of significantly reducing the number of covers installed.

Next, a second embodiment in which the present invention is applied to a cover having a width wider than the frame width will be described. In FIGS. 5 and 6, the frame width is extended and the guide wheel 12A is placed on it.
