Abstract: The present invention discloses a rotary-type electric flat trolley for container transportation comprising a base frame; a set of wheels provided on both sides of the base frame; wheel driving means provided on each set of wheels for driving the set of wheels; a rotary platform mounted on the base frame via rotary supporting means; a rotary mechanism connected with the rotary supporting means; and rotary driving means for driving the rotary mechanism. Thus, the container transportation from the frontside to the backside is accomplished, and the turning of the 90 degrees between the arrangement direction of the containers on the ship and that on the yard is also accomplished, which greatly increases the speed of horizontal transportation between the bank-side crane and the yard crane in the container terminal, and solves the problem of 90 degrees rotation.

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.
