PURPOSE:To prevent a container from dropping even if engagement between an engaging arm and a hook piece comes off, by supporting a handling arm pivotally in a dump frame free of longitudinal movements, while installing the engaging arm, engaging or disengaging to or from the hook piece, in this dump frame. CONSTITUTION:A dump frame 3 is pivotally supported on a rear end part of a subframe 2 and so designed as to be tiltable rearward. A handling arm 5 is pivotally supported on the frame 3 and of L-shaped form capable of moving in both directions, while a hook 10 is pivotally supported on a front end of the dump frame free of turning motion, and the handling arm 5 corresponding to this hook 10 is provided with an engaging part 11. A clamping device 9 is constituted of a hook piece tightly attached to a bottom surface of a container 7 and an engaging arm 13 pivotally supported on the dump frame 3 free of rocking motion in both directions. And, the hook 10 and the engaging arm 13 are coupled together through a connecting member 14, and in conformity with engagement and disengagement between the engaging arm 13 and the hook piece 12, the hook 10 and the engaging part 11 also are made to engage and disengage in design.
