Small and medium-sized dump trucks are not only used for transporting earth and sand like large dump trucks, but are also used for multiple purposes such as transporting materials, and are equipped with a tailgate lifter because they often carry heavy loads. However, when transporting earth and sand, as shown in Figure 6, the tailgate panel is opened horizontally and the loading platform is tilted to unload the cargo, so the pile of unloaded cargo gets stuck on the tailgate panel. If the cargo bed was returned to its original position like a large dump truck in this condition, the tailgate panel would scoop up the fallen dirt, and its weight could damage the tailgate lifter. This invention eliminates such drawbacks and can be used not only for earth and sand but also for materials.
The purpose is to easily transport equipment using a lifter.

Since this invention is constructed as described above, when transporting construction materials, equipment, etc., in order to load them onto the loading platform 2, the both side locking shafts 17, 17 must first be pulled inward. Remove the tips from the locking holes 19, 19 of the inner side frames 13, 13, and rotate the locking claws 20, 20 at the lower end to release the tightening of the lower end engaging portions 21, 21 of the tailgate panel 15. do. The panel 15 is then folded down to form a horizontal support surface. Next, the engaging part 7 of the main pillars 1, 1
Hold the handle 4 and raise it forward, and rotate the hook 5 connected to it in that direction, and the fourth
As shown in the figure, the upper engaging part 7 of the main pillars 1, 1,
The engaging holes 6, 6 of 7 constitute openings 3, 3 on the rear surface,
The support shafts 12, 12 are unlocked. Then, the drive units 9, 9 are activated to rotate the driving arms 10, 10 rearward, and the stay arm 11 follows this, so that the side frames 8,
8, and the tailgate panel 15 supported thereon is lowered and landed on the road surface. Next, when the driving arms 10, 10 are rotated forward and upward in the opposite direction, the tailgate panel 15 rises and aligns with the floor of the loading platform 2, and the side frames 8, 8 are connected to the main pillars 1, 1. and stop. At this time, spindle 1
2 and 12 are fitted again into the engagement holes 6 and 6 of the engagement portions 7 and 7 at the upper ends of the main pillars 1 and 1, respectively. So handle 4,
4 toward the front, the hooking alloys 5, 5 rotate and lock the hooking holes 6, 6. In this way, heavy objects can be placed on the tailgate panel 15, and materials and equipment can be easily loaded and unloaded.

Next, the earth and sand is transported by locking the engaging parts 7, 7 at the upper ends of the main pillars and the lower end engaging parts 21, 21 of the tailgate panel 15, and when lowering it,
If the lower end locking claws 20, 20 are released, the tailgate panel 15 can be rotated about the upper end support shafts 12, 12, and the loading platform 2 is lifted and tilted, as shown in FIG. As shown, the tailgate panel 15 automatically opens around the support shafts 12, 12 due to the gravity of the load, and the loaded earth and sand can be slid down like a conventional dump truck. Even if the lower end of the tailgate panel 15 is buried in a pile of fallen earth and sand, it will be pulled upwards by the horizontal return operation of the loading platform, so it will not be subjected to any destructive load, that is, there is no risk of damage, and the dump truck can be moved. It can be moved.

As described above, according to this invention, inside the side frame, the support shaft is pivotally supported by the inner protruding part of the support shaft that engages with the engagement hole provided at the upper end of the main column erected on both sides of the rear end of the loading platform. In the engaged state, the tailgate panel can be freely rotated along with the inner side frame around the support shaft and operated like a conventional large dump truck, and there is no risk of damage to the tailgate panel, allowing for casual loading and unloading. It is possible to carry out work. Moreover, when converting to a lifter, by removing the upper side locking shaft that locks with the inner side frame, you can easily rotate the tailgate panel rearward around the base end and support it horizontally to use it as a cargo handling platform. Even when weight is added to this, the inner side frame maintains its horizontal position with the action of the stopper at the lower end, and as the side frame operates, it can be safely raised and lowered to lift heavy objects. be.
