PURPOSE:To enable unloading cargo from a dump truck at a desired position, by supporting the loading bed together with the inclining cylinder to be revolvable horizontally, and by making possible to lock its revolving at a desired place, as well as allowing dumping action in the locked position. CONSTITUTION:Related to a coupler 18 in the controlling gear section 16 where the engine 22 is mounted, the supporting frame 2 has, at its front position, a coupler 17 which is connected to be revolvable horizontally through a supporting pin 19. Nearly at the center of the supporting frame 2 is installed a hub 3 which supports the revolving shaft 5. On the revolving shaft 5, the dump bed 6 is supported inclinably around a horizontal pin 8, which enables dump action by an expanding action of a hydraulic cylinder 9 placed between the bottom of the bed 6 and the lower part of the volving shaft 5. And a receiving pulley 11, which is a part of the revolving system operated by a handle 14, is fixed on the revolving shaft 5. Furthermore, a locking device 15 to lock the revolving of the bump bed 6 isfurnished related to the driving pulley 12. |
