To provide a quay crane capable of increasing a sliding distance without permitting upsizing of a seismic isolator.SOLUTION: In a seismic isolator 6, laminated rubber 9 is arranged between an upper flange and a lower flange 8. A rail 11, the extension direction of which is set to be a traverse direction x, is installed in either the upper flange or the lower flange 8. A plurality of contact members, which are constituted to be capable of coming into contact with a side surface 11b of the rail 11 having the traverse direction x set to be a surface direction, are installed in the other one. The contact member is brought into contact with the side surface 11b of the rail 11 so as to inhibit rotation of the seismic isolator 6 having a vertical direction set to be a central axis.SELECTED DRAWING: Figure 3

    【課題】免震装置を大型化させることなく摺動距離を拡大できる岸壁クレーンを提供する。【解決手段】上フランジと下フランジ8との間に積層ゴム9を配置された免震装置6において、上フランジまたは下フランジ8の一方に延在方向を横行方向xとするレール11を設置して、他方に横行方向xを面方向とするレール11の側面11bと接触可能に構成される複数の接触部材を設置して、レール11の側面11bに接触部材を接触させることで上下方向を中心軸とする免震装置6の回転を阻止する。【選択図】図3
