Abstract

Embodiments of the present invention include quayside cranes and yard cranes related by a low elevated transfer system and a ground transportation carrier system. The low elevated transfer system includes low elevated transfer subsystems having low elevated rails, the low elevates rails include low elevated crane rails and low elevated flat carrier rails, low elevated cranes are disposed on the low elevated crane rails and low elevated flat carriers are disposed on the low elevated flat carrier rail. The ground transportation carrier system includes ground transportation carrier rails and transportation carriers moving along the ground transportation carrier rails. Embodiments of the present invention transport the containers by rails and use municipal electric as the power supply. A three-dimensional low elevated transfer system and a ground transportation carrier system are provided to implement three-dimensional transportation of containers. Embodiments of the present invention provide a container transportation schema that is efficient, power saving, environmental and automatic, ground resources are utilized with high efficiency. The present invention is an expansion and development of the invention provided in CN 200510111464.0.

Abstract

The present invention discloses an arrangement scheme of a container wharf, in which the containers positioned in the yard is arranged in a direction being perpendicular to the direction of the containers positioned in the ship, comprising: a quayside container crane for loading/unloading containers in the first direction; a low elevated system including low elevated track, low elevated system lifting trolley and low elevated system plane carriers, the low elevated system plane carrier can be operated by the low elevated system lifting trolley and the low elevated system can be operated by the quayside container crane; a transportation carriers system including transportation carrier track along the second direction and transportation carriers being able to rotate 90 degrees together with container put thereon, the transportation system can be operated by the low elevated system; a yard crane having a yard crane track along the second direction for loading/unloading the containers with the yard. The arrangement scheme of the container wharf according to the present invention increases the efficiency and technical level of the container handling port significantly.

Abstract

The present invention relates to a double-trolley container crane capable of lifting dual 40-foot containers. The crane is equipped with two trolleys, the front trolley is mounted on the upper track of a crane girder and runs on the upper track, the rear trolley is mounted on the lower track of the cross beam of a gate frame and runs on the lower track. A transfer platform for container positioning is set under the crossbeam of the gate frame. By running on the corresponding tracks, the front trolley can lift two 40-foot containers onto the transfer platform, and then the rear trolley can lift and transfer the containers on the transfer platform onto the ground transportation truck one-by-one, and vice versa. The front trolley can lift two 40-foot containers side-by-side one time. Since the rear trolley can start to lift the containers at very low height and can move very short distance, so it successfully resolves the problem about the positioning and swaying of the containers during the operation between the crane and the ground transportation truck. The present invention greatly raises the speed and efficiency of loading-unloading during the operation between the cargo ship and the ground transportation truck. It could be adapted to be used both in automated dock and in normal dock.
