To provide a frame lifting device for a vessel capable of safely mooring a vessel by securing a sufficient lifting height of a bottom of the vessel.SOLUTION: A frame lifting device 6 for a vessel provided on a platform 2 for lifting a frame 5 mounting a vessel 7 as well as supporting it includes: a hanging member 86 having a movable end 86a connected to the frame and a fixed end 86b connected to the platform; a hanging member supporting body 83 with the hanging member hung in a reverse U-shape; and a frame lifting cylinder 80 for lifting the hanging member supporting body. When the hanging member supporting body is lifted by the frame lifting cylinder, the frame is lifted between a mooring position in which the vessel is moored in a splashdown state and an evading position in which the vessel does not receive influence of rising of the sea level by lifting the moving end of the hanging member.SELECTED DRAWING: Figure 5
【課題】船底の吊り上げ高さを十分に確保することによって船舶を安全に係留できる、船舶用の架台昇降装置を提供する。【解決手段】プラットフォーム2に設けられて、船舶7を載置し且つ支持する架台5を昇降させる船舶用の架台昇降装置6であって、船舶用の架台昇降装置は、架台に接続される可動端86aと、プラットフォームに接続される固定端86bとを有する吊り部材86と、吊り部材が逆U字状に架け渡される吊り部材支持体83と、吊り部材支持体を昇降させる架台昇降シリンダ80とを備え、架台昇降シリンダで吊り部材支持体を昇降させると、吊り部材の可動端が昇降することにより、船舶が着水状態で係留される係留位置と、船舶が海面上昇の影響を受けない退避位置との間で架台が昇降する。【選択図】図5
