can be erected on the side edge of the floorboard 11.

Further, a rear wall 20 is removably supported by a shaft 25 at the upper rear end of the side wall 19, so that the rear wall 20 can be detached from the side wall 19 as required.

An engagement/disengagement mechanism E is provided between the bottom surface of the cargo box C and the cargo handling frame 7 to connect them together or to separate them. The structure of this engaging/disengaging mechanism E will be explained below. An engaging hook 21 is fixed to the bottom surface of the cargo box a.
Further, the cargo handling frame 'FK has an engaging hook 21 fixed to the engaged hook 22 which can be engaged and disengaged, and when the cargo box 0 is pulled up onto the cargo handling frame F, the engaging hook 21 is attached to the engaged hook 22.
2, and when the cargo box O slides down from the cargo handling frame F, the engagement hook 21 can be detached from the engaged hook 22.

5 In the figure, 26 is a bin provided to prevent the bin 18 from being removed from the shipping box, and 24 is an empty cargo box a'f: when stacking, the bin 18 is separated from the floor board 11 and another cargo box C. main digit 1
This is a sleeper that is installed between the two.

Next, the operation of the present invention will be described. As shown in FIG. 2, the cargo handling frame F is rotated rearward, and the 7° angle H is engaged with the locking bin 16 on the cargo box O side.

Next, by contracting the lift cylinder 9, the telescopic frame 4 can be rotated forward and installed on the chassis 1.
The cargo box O can be pulled up and placed on the vehicle platform 1 with the guidance of guide rollers 10.

Finally, the telescopic cylinder 8 is extended and the cargo box O can be mounted at a predetermined position on the vehicle chassis 1, as shown in FIG.

In this way, the cargo handling vehicle can be driven and the contents loaded in the cargo box can be transported to an appropriate location.
