Then, the top panel 54 is placed on the vehicle body 1 with the operator seat 55 facing the instrument panel assembly 17 side, and the rear end is rotatably mounted on the vehicle body 1 via the hinge member 56. . Further, if necessary, a towing vehicle can be constructed by detachably mounting the loading platform guard 50 on the vehicle main body 1 behind the top panel 54. At this time, the steering wheels are located in the front, so running stability can be improved.

Next, when the vehicle is to be used as a forklift, a forklift mast assembly is attached to one mounting bracket portion 12 of the vehicle body 1 so that the drive wheel 7 becomes the front wheel as shown in FIGS. 3 and 4. 34 and the forklift counterweight 47 are removably attached to the other mounting bracket portion 13 in the manner described above. This type of mast assembly 34, which does not involve tilting, has good support because it is fixed by two fixing parts M at the top and bottom of one side, and the top surface of the forklift counterweight 47 is approximately the same as the top surface of the vehicle body frame 2. Since it is mounted at the same height, it can be supported by the entire mounting bracket part 13 without detracting from its appearance, even though it is heavy. Durability is also improved because the load is not concentrated locally. and,
The top panel 54 is placed on the vehicle body 1 with the operator's seat 55 facing the mast assembly 34 side, and the rear end is rotatably mounted on the counterweight 47 via the hinge member 56 to create a forklift. can be configured.

In this case, by using various attachments 38 attached to the carriage 37, the carriage 37 can be used as a ram lift, a side clamp, etc. in addition to a forklift, depending on the load role.

Effects of the Invention As described above, according to the present invention, the main parts of the car body such as the car body and the top panel are shared, and a mast assembly for a forklift is attached to the mounting brackets formed at both the front and rear ends of the car body. , forklift counterweight or tow vehicle instrument panel assembly,
By selectively attaching a counterweight for towing vehicles and changing the orientation of the top panel to suit the intended vehicle, it can be used for multiple purposes as a forklift or as a towing vehicle. This has a great practical effect in that it is possible to further improve the handling of the dealer and the usability of the user, and also to realize a significant cost reduction.
