PROBLEM TO BE SOLVED: To provide a quay crane that can cope with enlargement of a seismic isolator and improve a seismic isolation performance.SOLUTION: Seismic isolators 17 are arranged in leg-connection horizontal beam members 6 that connect pier legs to landside legs 3, and a sub frame structure body 18 having a structure for suspending a slide type boom 5 is arranged in the seismic isolators 17. The sub frame structure 18 has: a sub frame upper-end beam member 20 which is extended in a running direction y of a quay crane 1 and supported to the seismic isolators 17; and a pair of boom suspending arms 21 that are separated in an extending direction of the sub frame upper-end beam member 20 and extended downward from the sub frame upper-end beam member 20. The slide type boom 5 is arranged between the pair of boom suspending arms 21 and supported to supporting members arranged in the boom suspending arms 21.SELECTED DRAWING: Figure 3
