8. Deck Machineries
In the field of deck machinery in 1999, the developments of the high productive container crane "SUPERTAINER" and the high pressure typed hydraulic deck machinery "ADVANCED SERIES" were performed. The further details are described as follows.
8.1 Development of High Productive Container Crane "SUPERTAINER"l)
To provide more and more economical container transportation, future container ships will have to be increasingly larger. In line with this trend, container terminals would require installations of quayside container cranes having excellent performance with ease of operation.
In view of such needs, Mitsui Engineering & Shipbuilding Co., Ltd, and PACECO Corp have jointly developed a new and highly productive container crane called "SUPERTALNER Crane". The crane has a concept of conveying containers by the sc-called "bucket relay" method, consisting of two trolleys, one traverser and one container chute. The handling productivity of this crane is approximately 3 times that of a conventional container crane.
Fig.8.1 shows the general arrangement of the "SUPERTAINER" crane. Fig.8.2 shows the sea-side trolley and the traverser arrangement. The container chute in Fig.8.1 is the guiding mechanism for putting the container suspended by the landward trolley to the landward chassis or the automatic transportation vehicle (AGV). The landward / sea-side trolleys and the traverser are installed on the two girders, both trolleys moves on the inside rail of the girder, the traverser moves on the outside rail of it. As a result, the traverser and the trolley can intersect each other at the turning point of the container. There is one operator's room on the sea-side trolley and landward respectively. The operator in the sea-side room can handle a cargo on the vessel and control the whole operation of the crane.
The operator in the landward room makes a cargo handling on the quay, but the landward cargo handling is able to be unmanned at the automatic operation container terminal. On handling the container, all handling operations (hoisting a container on the vessel to the sea-side trolley, conveying one by the traverser, reloading one between the trolley and the traverser, winding off one to the container chute etc.) are fully automatic. Therefore the sea-side operator performs only deciding the position of a container on the vessel, catching on one, taking off one and hoisting one to the safety height.
