する。First, as shown in FIG. 1, in a state where the luggage box 5 is in a horizontal traveling posture, the jack cylinder 40 is extended, and the jack cylinder 40 is rotated counterclockwise in FIGS. It is placed at a position (see the chain double-dashed line in FIGS. 1 and 4) that projects slightly rearward from the position. At this time, the interlocking arm 31 also pivots in the same direction as the jack cylinder 40 pivots, and the link mechanism 30 interlocks with the pivoting of the interlocking arm 31 as described above, and the tip portion 20a of the locking pin 20. Project laterally, whereby the tip end portion 20a of the locking pin 20 and the engaging member 13 of the regulating member 10 are brought into an engaged state. When the dump cylinder is extended with the tip 20a of the locking pin 20 and the engaging member 13 of the regulating member 10 thus engaged, the support frame 2 and the luggage box mounted on the support frame 2 are extended. 5 is tilted about the pivot 3, and the locking pin 20 provided on the support frame 2 is a cylindrical body of the rod 12 of the regulating member 10.
Pull upward from 11. Then, the piston 15 connected to the lower end of the rod 12 moves upward in the cylindrical body 11 and contacts the stopper 14. As a result, the extension of the rod 12 is restricted, and as a result, the tilting motion of the support frame 2 and the luggage box 5 is restricted. That is, the support frame 2 and the packing box 5 do not dump beyond this inclination angle. At this time, the jack cylinder 40 is rotated in the clockwise direction in FIGS. 1 and 4 by the tilt angle of the support frame 2 as the support frame 2 is tilted to be in a substantially vertical state (FIG. 4). (See dashed line). As a result, the grounding member 41 provided on the tip portion 40b of the jack cylinder 40 abuts on the ground, and supports both rear sides of the support frame 2.

動作によって行われる。After that, by extending the slide cylinder 6, the luggage box 5 slides backward on the support frame 2 so that the rear end of the luggage box 5 approaches the ground, and the left and right sides of the rear edge of the luggage box 5 are brought closer to the ground. The support roller 7 provided is brought into contact with the ground to support the rear end of the luggage box 5.
At this time, since the rear portion of the support frame 2 is supported by the jack cylinder 40, the luggage box 5 can be slid backward safely. After that, the tailgate 8 of the luggage box 5 is released, and the walking boards 9 and 9 are installed between the rear end of the luggage box 5 and the ground according to the width of the wheels, whereby the vehicle between the luggage box 5 and the ground is installed. Can be loaded and unloaded (see Fig. 2). Further, when returning the luggage box 5 to the traveling posture from this state, the operation is reverse to the operation described above.

At this time of tilting, the restricting member 10 and the locking pin 20 are not engaged, so that the support frame 2 and the packing box 5
Can tilt up to the maximum tilt angle. Therefore, this dump truck can be used both for transporting construction machines and vehicles such as passenger cars and for transporting sand and gravel.

などを積卸しでき作業の安全性を高めることができる。(Effect of the Invention) As described above, according to the present invention, the inclination angle is regulated by engaging the regulation member and the locking member so that the support frame on which the luggage box is mounted does not tilt more than a predetermined angle. Therefore, when loading and unloading a vehicle or the like, the loading box does not tilt to a dangerous state, and the vehicle or the like can always be loaded and unloaded in a stable state, and the work safety can be improved.
