<p>PURPOSE:To gain easy access to a load bed, by providing a staircase-shaped step in a sideward-swing door in its internal surface while enabling the sideward- swing door to be turned by a driving means and the sideward-swing door itself to be utilized as the staircase under a condition that the upper end edge of the sideward swing door is connected onto the ground. CONSTITUTION:A truck forms in its load housing 1 longitudinally three sheets of sideward-swing doors 3 in a load housing main unit 2 to be turnably supported around to hinges formed in bottom end edges 4 of these sideward- swing doors 3. Staircase-shaped steps 6, which are mounted to each sideward- swing door 3 in its internal surface, are used so as to function as the staircase, when a cargo handling worker gains access in the load housing 1, in a condition that the sideward-swing door 3 is opened connecting its upper end edge 5 to the ground. And each sideward-swing door 3 is constituted so that it is actuated opening and closing through a link mechanism 9 by actuating an opening and closing cylinder 8.</p> |
