PROBLEM TO BE SOLVED: To provide a small boat lifting and recovery device which enables the lifting and recovery of both an unmanned small boat by remote control operation with no suspension ropes and a manned small boat to be liberated from the risk of a suspension rope work.SOLUTION: The top of an installation table 1 matched with positions on the bow side and the stern side of a lifting and recovery small boat provided on the top of a deck of a lifting and recovery side vessel or a harbor quay floor is equipped with support arms 8b, 8c for scooping up the bow side and the stern side of the bottom of the lifting and recovery small boat at the tip of a multistage telescopic frame 50 expandable to and contractible from two turning arms 2 in a direction nearly perpendicular to the deck surface or the quay floor surface, and the turning arms are swung out to immerse the respective support arms in water to a constant depth by elongating the multistage telescopic frame. Further, a bow side support arm 8b is equipped with an approach marker serving as an approach target of the lifting and recovery small boat to eject the approach marker out of water to a constant height from a water level for standing by to make a lifting and recovery small boat approach by positioning, and then the multistage telescopic frame is moved by contraction to further turn the turning arm for lifting and recovery, while the delivery is based on a reverse operation against the same.SELECTED DRAWING: Figure 1
【課題】無人小型艇でも吊り索を使用せず遠隔操作によってまた有人の小型艇の揚収でも吊り索作業の危険から解放される、小型艇揚収装置を提供する。【解決手段】揚収側船舶の甲板上や港湾岸床に備えた揚収小型艇の艇首側と艇尾側の位置に合わせた設置台1上に、2連の回動アーム2に甲板面や岸床面に略鉛直方向に伸縮可能な多段伸縮フレーム50の先端に、揚収小型艇の船底の艇主側と艇尾側をすくい上げるための支持アーム8b、8cを備え、回動アームを振り出し、それぞれの支持アーム、を多段伸縮フレームを伸長させ一定の深度まで水中に没しさせ、さらに艇首側支持アーム8bには、揚収小型艇の進入入目標となる進入標識体を備え、水中より水上面から一定の高さまで進入標識体を突き出し待機し、揚収する小型艇を位置決め進入させた後、多段伸縮フレームを縮動させ、さらに回動アームを回動し揚収する、また繰り出しはその逆動作することによる。【選択図】図1
