PROBLEM TO BE SOLVED: To provide a marine vessel lifting device which has a simple structure and can safely lift small ships of different sizes in a prescribed range while holding the ships in a normal posture.SOLUTION: A marine vessel lifting device 1, which is configured from a first carriage 2 and a second carriage 5 on which a bottom surface of a marine vessel 10 is loaded, has: connection means 7 which connects the first carriage and the second carriage so as to be capable of changing a space between those carriages; and marine vessel holding means 3 which holds left and right side faces of the marine vessel so that a direction of the vessel loaded on the first carriage and the second carriage is coincident with a direction of movement of the first carriage and the second carriage. The marine vessel holding means comprises plural holding masts which are perpendicularly erected on the first carriage two by two with a prescribed space between themselves and the left and right side faces of the marine vessel, and an advancing and retracting mechanism which can be capable of advancing and retracting the holding mast so that the holding mast approaches and is separated from the heft and right side faces of the marine vessel.SELECTED DRAWING: Figure 1

    【課題】単純な構造で、しかも所定範囲内の大きさの異なる小型船舶を台車上に正規の姿勢で挟持して、安全に揚降できる船舶揚降装置を提供する。【解決手段】船舶10の底面を載置する第1の台車2及び第2の台車5により構成される船舶揚降装置1であって、第1の台車と第2の台車との間隔を変更可能に連結する連結手段7と、第1の台車及び第2の台車上に載置する船舶の向きが、第1の台車及び第2の台車の移動方向と一致するように、船舶の左右側面を挟持する船舶挟持手段3と、を有し、船舶挟持手段は、第1の台車上に、船舶の左右側面に所定間隔を空けて二本ずつ垂直に立設された複数の挟持マストと、挟持マストを船舶の左右側面に近接、離反するように進退可能とした進退機構と、を備えたことを特徴とする船舶揚降装置とした。【選択図】図1
