<p>PURPOSE:To enable dump doors to bind even when the binding portions do not meet, by providing removable and revolvable rear dump door at the rear top portion, by providing an inclined piece and a latch at its lower end, and providing a hood piece and a hook on a load carrying platform and operating the hook by turning movement of the platform. CONSTITUTION:Returning a platform 2 to a slantless position, a roller 18 touches a guide piece 19 and turns backward to turn an arm lever 17, pushes forward a connection rod 15 against a spring 16, and turns a hook 10 to the closing position. Then, a tip of the hook 10 joins together a shaft of a hook piece 11 and binds the rear dump door 6 in the close mode. Even when the rear dump door 6 is in gap rear wards, a hook 12 is moved to reverse direction of the gap along the inclined piece 9 as the revolving, because a corner of the hook 10 gets in toutch with the inclined piece 9 of the hook 12 opposite to the direction of the gap. This binds the hook 10 to the hook piece 11 while correcting the gap of the rear dump door.</p> |
