After the introduction of the World Trade Organization, large scale container ships are being used as a means of transportation for international trade. Therefore, improving the loading and unloading capability of container quays is the most economic way, considering the cost needed for the establishment or expansion of container quays. In this paper, a new container cargo handing system that is equipped with a high performance container crane is suggested. A structural analysis on the container crane is also conducted to decide the form and size of structural member scantlings, using NASTRAN, which is a general structure analysis program.
