in this paper. The first ten natural frequencies, the corresponding mode shapes and time-history of displacement response

are given based on the analysis of the modes and dynamic response of this gantry crane system. The calculation and

analysis above may be helpful for preventing the gantry crane from working on resonant area and for keeping the

oversize dynamic deformation under restraint, which can be applied to design quayside gantry crane systems.
