(Problems to be Solved by the Invention) According to the above configuration, since the rollers of the fixed table and the turntable are arranged side by side so as to be rotatable only in the front and rear directions, it is difficult to install this trailer in the luggage loading/unloading section of an aircraft. When loading and unloading containers from the side of a high-lift loader, each roller of the turntable is placed horizontally against the side of a high-lift loader, and when loading and unloading a container from the side. It is necessary to horizontally rotate this turntable approximately 90 degrees so that the container is facing toward Since a unique oil part is formed in the turntable, it is necessary to move the container on the turntable onto a fixed table so that this oil part does not protrude outward. In addition, when this trailer is placed horizontally against the front side of the high-lift loader and a container is loaded or unloaded from the front, the turntable can be rotated and returned in the same manner as in the case of side loading. It is necessary to rotate and also to move the container onto a fixed table.
