Containers are used for the transportation of most export/import materials through ports in general, and world container shipping liner companies are expanding their global networking by increasing the size and speed of their ships, enforcing strategic alliances between shipping companies in order to reduce logistic costs and times. Therefore, they are intended to prefer more efficient and quickly responsive ports. Ports over major sea routes contend each other for more swift disposal of containers and competitive advantages in diverse ways, and one of these ways is to increase the size and speed of container handling devices. The spreader is equipped in major container handling devices such as container crane, transfer crane, reach stacker with function to hold the container for transferring it into a place of destination, and operates in mostly severe conditions. This study compares and analyze merits and demerits of two types of the spreader to be equipped in container handling devices which will be manufactured; one is oil pressure spreader as the traditional type and the other is electronic spreader as the recent type. And this study is also expected to help selecting more productive and pro-environmental container handling devices through reduction of maintenance costs and personnels.
