Recently many countries have concentrated their effort on the port automation, in order to be the Hub-port, that the ULCS (Ultra Large Container Ship) could come alongside the quay in their region. As the magnitude of the container ship increases, that of the container crane (used in quay) increases from 50ton-class to 61ton-class more and more. The wind velocity criteria to design the structures used in the port was upgraded from 30m/s to 40m/s due to change of the weather condition.
When we design wedge type rail clamp which can protect container crane from sudden wind blast with constant clamping force regardless of the operating period, it is important to determine the angle of wedge within proper range. In this study we designed the wedge angle of the wedge-type rail clamp using the FEA.
