てし・る。Further, the base end of the cylinder 14 attached to the connecting rod 15 is pivotally connected to a bracket 19 fixed to the chassis 2 by means of a pin 20.
ところで、シャフト１１の両側端部には前記ブラケット
１６と同形状のブラ′ｒ７）２１がシャツ）１１と一体
に回動するように固着されている。By the way, bras 21 having the same shape as the bracket 16 are fixed to both ends of the shaft 11 so as to rotate together with the shirt 11.
そしてこのブラケット２１とフレーム延長部材２２との
間には、弾性部材２６が装着されており、７ツク１０を
起立方向に付勢するように介設されている。An elastic member 26 is installed between the bracket 21 and the frame extension member 22, and is interposed so as to bias the seven hooks 10 in the upright direction.
尚、２４はフック１０の傾倒位置を規制するストッパで
ある。Note that 24 is a stopper that restricts the tilting position of the hook 10.
一方、前記シリンダ１４の給排口に一端が接続された配

に接続され、また切換弁２７の０ボートは配管６０によ
ってタンク２８に、Ｄポートは配管３１によってポンプ
２９を介しタンク２８にそれぞれ接続されている。On the other hand, the other end of the piping 25, 26, one end of which is connected to the supply/discharge port of the cylinder 14, is connected to the A and B boats of the switching valve 27. , D ports are connected to the tank 28 via the pump 29 by piping 31, respectively.
尚、前記切換弁２７の中立位置においては、Ａボートと
Ｂホ゛−トがタンク２８に連通されている。Incidentally, when the switching valve 27 is in the neutral position, the A boat and the B boat are communicated with the tank 28.
次に、上記実施例の作用を説明すれば、まず、荷箱６を
車台２と地上との間で積み卸しする場合には、切換弁２
７をａ方向に切り換えることによってフック用シリンダ
１４のロッドを伸長させ、フック１０を後方に傾倒させ
て、７ツク１０と荷箱６の係合部材９とが係合不能な状
態にして行う。Next, to explain the operation of the above embodiment, first, when loading and unloading the cargo box 6 between the vehicle platform 2 and the ground, the switching valve 2 is
By switching the hook 7 in the direction a, the rod of the hook cylinder 14 is extended, the hook 10 is tilted backward, and the hook 7 and the engaging member 9 of the cargo box 6 are in a state where they cannot be engaged.
すなわち、第１図に２点鎖線で示す荷箱６が地上にある
状態からホイストシリンダ５を短縮すると、アーム６の
回動に伴って荷箱６を吊り上げた後に前方へ移動して、
実線で示すように荷箱６を車台２上に搭載するものであ

を中心として傾動しダンプを行う。On the other hand, when dumping the cargo box 6 on the vehicle chassis 2, first switch the switching valve 27 in the b direction to shorten the rod of the hook cylinder 14 and rotate the hook 10 upright, and then switch the switching valve 27 to the b direction. The hoist cylinder 5 is switched to the neutral position and the hoist cylinder 5 is extended while the seven hooks 10 are engaged with the engaging members 9 of the cargo box 6. Hoist cylinder 5
The cargo box 6 attempts to be lifted by the rotation of the arm 3 as the arm 3 extends, but due to the engagement between the hook 10 and the engaging member 9, the cargo box 6 is not engaged, as shown by the dashed line in FIG. Joining member 9
It tilts around the center and dumps.
