Container transportation carrier and container transportation system

Abstract

The present invention discloses a container transportation carrier comprising: a bottom frame; a set of wheels, mounted on said bottom frame, said set of wheels being positioned on a set of tracks so that said container transportation carrier travels along the tracks; wheel driving means, mounted on said bottom frame, for driving said set of wheels; rotary mechanism, mounted on said bottom frame, being rotatable with respect to said bottom frame; a rotary platform, spanned on said rotary mechanism by rotary supporting means, with containers positioned on said rotary platform; rotary driving means, mounted on said bottom frame, for driving said rotary mechanism to rotate said rotary platform. The present invention also discloses a container transportation system and a whole arrangement scheme of container wharf using the above transportation carrier. Using the technical solutions of the present invention, the speed of transportation between cranes at shore of container wharf and ones at the container yard will be significantly increased and the problem of 90-degree rotation will be solved. In addition, the handling way can be used at non-automatic wharfs, and, preferably, at automatic wharfs. The advantage of efficient handling is to enhance efficiency and technical level of the container handling port.
