摘要： Provided is a quay crane which includes a seismic isolation device formed from laminated rubber, and which is capable of withstanding a large-scale earthquake. Particularly, provided is a quay crane including a seismic isolation device with a slide length of 1000 mm or over. In a quay crane including a seismic isolation device, the seismic isolation device includes: laminated rubber formed by laminating a steel plate and a rubber material; and an auxiliary support mechanism. The auxiliary support mechanism includes: a supporting body fixed to one of a top plate side and a bottom plate side of the seismic isolation device; and a contacting plate fixed to the other thereof. The supporting body and the contacting plate constituting the auxiliary support mechanism come into contact with each other at least in the event of an earthquake, and the auxiliary support mechanism supports a weight of the quay crane.
