PURPOSE:To enable free and effective dumping of loads, despite obstacles at the upper part of dumping space, by making a rear door and a support frame housed underneath the loading chassis. CONSTITUTION:The lower part from the position of a support frame rotary axis 13, fixed to a vertical frame 2, is a rotation stopper 16, and when a rear or 1 is rotated to open around the axis of the support frame rotary axis 13 in the direction of arrow A, the corresponding part 16 works on the lower surface of a rear door housing guide 17 and the rear door 1 is stopped after rotation of 90 deg.. The support rotary axis 13, a rotation stopper 16, the rear door housing guide 17 and an axis guide slot 14, constitute a part of the rear door housing device. In this way, the rear door 1 can be housed underneath a loading chassis when dumping, enabling free and effective dumping of loads, despite obstacles at the upper part of a working space. |
