The panel member 2 is restrained by the belt 14 and can be prevented from dropping from the carrier 1 of the panel member. Then, when the worker enters between the pair of handles 5 and lifts both handles 5, the curved portion 20 of the stand 9 is lifted off the ground as shown in FIG. The panel material 2 is transported by pushing the handle 5 toward the direction.

  As described above, according to the panel material transport trolley 1 of the present embodiment, the panel materials 2 can be loaded in two methods, horizontal and vertical, so that the number of panel materials 2 to be transported and the number of panel materials 2 Horizontal or vertical placement can be selected in consideration of factors such as the size and width of the passage. That is, in the case of the vertical installation, there is an advantage that the panel member 2 can be transported even in a narrow passage. However, even when the panel member 2 is small or the number of panel members 2 to be transported is large, And only four panel members 2 can be transported at one time. On the other hand, in the case of the horizontal placement, the panel material 2 protrudes in the left and right direction of the transport cart 1 of the panel material, so that it is difficult to pass when the passage is narrow. The number of panel materials 2 to be used can be increased, and depending on the dimensions of the panel materials 2, there is an advantage that more panel materials 2 can be transported at once by loading the panel materials 2 back and forth.

  Further, when the panel material 2 is placed vertically, the panel material 2 can be loaded from the front of the panel material carrier 1 or the panel material 2 can be loaded from the rear of the panel material carrier 1. Even when the loading operation of the panel material 2 is performed in a place where it is difficult to move the panel material 2 around the transporting trolley 1, the panel material 2 can be easily loaded.

  It goes without saying that the embodiment of the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the scope of the concept of the present invention.

  The transport trolley 1 of the panel material according to the present invention is suitable for transporting formwork panels used for, for example, foundation work.
