The invention relates to the technical field of lifting rings, and discloses a lifting ring special for a movable deck of an automobile roll-on-roll-off ship and a lifting method.The lifting ring comprises a lifting ring body fixed to the movable deck, the lifting ring body comprises a lifting ring nut, a rotating bolt, a base plate and a nut, the lifting ring nut and the rotating bolt are of an integrated structure, and the base plate and the nut are of an independent structure; the lifting ring nut and the swivel bolt are arranged on the non-structural surface side of the movable deck, the base plate and the nut are arranged on the structural surface side of the movable deck, and the swivel bolt penetrates through a fixing plate of the movable deck and is screwed through the nut. According to the device, the lifting ring nut is fixed to the movable deck through the rotating bolt and the rotating nut, connection is stable after the device is installed, the structural stability is high, and the device is convenient to disassemble and more convenient to use. When the device is used, it is ensured that the swivel bolt clamps the movable deck, that is, the lifting ring nut can horizontally and freely rotate by 360 degrees, efficient and safe overturning and lifting operation of the movable deck can be met, and deformation in the manufacturing and lifting process is reduced.
