The invention discloses a lifting device for a ship and the ship. The lifting device comprises a fixed rod, a reinforcing frame, a rotating disc, a swing rod, a first winding rum and a second winding drum; the top end of the fixed rod is hinged with a first pulley; the reinforcing frame is fixedly arranged at the bottom end of the fixed rod; the rotating disc is rotationally mounted on the reinforcing frame; one end of the swing rod is rotationally connected with the rotating disc, and the other end of the swing rod is hinged with a second pulley and a third pulley; a first steel wire rope winds around the first winding drum, and one end of the first steel wire rope sequentially winds around the first pulley and the second pulley upwards to be connected with the top end of the fixed rod; a second steel wire rope winds around the second winding drum, and one end of the second steel wire rope winds around the third pulley upwards and then is downwards connected with a lifting hook. According to the device, angle adjustment of the swing rod in two directions can be realized, so that the lifting flexibility is greatly improved, and the device is convenient to use.
