Abstract

The present invention relates to a roll-on/roll-off (RO-RO) cassette with a cover which is opened or closed by rotating on a rotational shaft (2) on a main body (1) to load cargo. The RO-RO cassette includes: a tilting device which connects the front door (21) and the back surface unit of the cover in order not to collide with the main body and a loaded cargo during the opening of the cover; and makes the front door of the cover primarily slope by interlocking with the rotation of the back surface unit. The RO-RO cassette can load cargo as much as possible on the main body because the tilting device in the cover makes the front door of the cover primarily slope to open or close the cover in order to prevent contact with the cargo on the main body or the guide rail during the opening or closing of the hexahedral cover, can protect the cargo by covering the cargo with a box structure, and can maximize the efficiency of cargo transportation by loading other cargo in the overturned box structure during returning.
