Design of the various wedge type rail clamp for quay crane according to the design wind speed criteria changes

摘要

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 alongside the quay in their region. As the magnitude of the container ship increases, the size of the container crane (Quay Crane) increases more and more. The wind speed criteria to design the structures used in the port during an operation in Korea were intensified from the wind speed of 20m/s to 40m/s due to change of the weather conditions. We could have the ability to design the wedge type rail clamp for 50ton-class crane in wind speed of 20m/s. Accordingly we analyzed the load condition of the crane about the intensified design wind speed criteria of 40m/s and designed the wedge type rail clamp for 50ton-class crane.
