To provide a cradle raising/lowering device for a ship, which is able to safely moor a ship by sufficiently securing a lifting height for a ship.SOLUTION: In a cradle raising/lowering device 6 for a ship, for raising/lowering a cradle 5 disposed at a platform 2, the cradle 5 has: a placing base portion 42 on which the ship 7 is placed; and a placing-base support portion 41 supporting the placing base portion 42. The cradle raising/lowering device 6 for the ship has a cradle raising/lowering actuator 80 that is connected to the placing base support portion 41. The cradle raising/lowering actuator 80 is a telescopic extended/shortened cylinder 80 having an extended/shortened cylinder tube 81 and a plurality of piston rods 82, 83 concentrically provided in the extended/shortened cylinder tube 81. By driving a telescopic extended/shortened cylinder 80 hydraulically, a raising/lowering operation of the cradle 5 is performed between a mooring position where the ship 7 is moored in a state of landing on water and a retraction position where the ship 7 is not affected by a rise of a sea surface.SELECTED DRAWING: Figure 4
【課題】船舶の持ち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に配設される架台５を昇降させる船舶用の架台昇降装置６であって、架台５は、船舶７を載置する載置台部４２と、載置台部４２を支持する載置台支持部４１とを有し、船舶用の架台昇降装置６は、載置台支持部４１に接続される架台昇降アクチュエータ８０を有し、架台昇降アクチュエータ８０は、伸縮シリンダチューブ８１と、伸縮シリンダチューブ８１の内部に同心状に設けられた複数のピストンロッド８２，８３とを有するテレスコープ型の伸縮シリンダ８０であり、テレスコープ型の伸縮シリンダ８０を液圧で駆動することにより、船舶７が着水状態で係留される係留位置と、船舶７が海面上昇の影響を受けない退避位置との間での、架台５の昇降動作を行う。【選択図】図４
