The rear dump door 4 is fixed detachably to the strut 2 by means of a fixedly fastening device 9. An L-shaped bracket 15 is fast stuck to an upper section of a side edge of the side dump door 3, and a shaft 16 is erectly mounted to a plane section of the bracket. An operation lever 17 consists of a pawl 19 opposing to a hole 18 bored to the strut 2 and an operation lever 20, and pivotally mounted to said shaft 16. A connecting section 21 is pivotally mounted to the pawl 19, and a sliding lever 23 of the connecting section 21 is lifted and dropped by means of a link 25, and connected to a hole 27 of a sliding lever receiving member 26.</p> |
