PURPOSE:To prevent cargoes or loads from being stacked on the back side of a unloading plate by disconnecting the lower end of the unloading plate from the floor plate of a cargo deck when an unloading member and a sliding member as well are returned from the end position of unloading to the initial posiof unloading. CONSTITUTION:When unloading cargoes thrown from the upper part of a cargo deck, a rear flapping door 14 is opened and a piston rod 12' of a cylinder 12 is extended while a unloading member 5 and a sliding member 3 are moved backward in a sliding manner, forcibly lowering the unloading member 5. When the unloading member 5 is returned from the end position of unloading to the initial position of unloading, the first thing to do is to start the contraction of the cylinder 12. Then, the unloading member 5 and the sliding base 3 as well are moved forward in a sliding manner under the state where the unloading member 5 is kept off from the floor plate of the cargo deck 1. |
