  • Device for pulling out a ship
    Patent number: 8079779
    Abstract: An apparatus for hoisting a ship. A transfer truck located on the shore moves to the interior of a raising/lowering lift by means of a set of movable rails so as to be able to unload the ship floating on a water surface. Lift-side support blocks, which are spaced apart from each other, are gradually raised under water to float the ship on the water surface. Truck-side support blocks, which are spaced apart from each other in a manner similar to the lift-side support blocks, move to the interior of the raising/lowering lift. Thereby, the lift-side support blocks, which are spaced apart from each other, are lowered through gaps between the truck-side support blocks while crossing the truck-side support blocks so as to allow the ship to be safely unloaded.
