Title:
DEVICE FOR FLOATING SHIP OR LIFTING IMMERSED BOAT
Document Type and Number:
WIPO Patent Application WO/2015/182997
Kind Code:
A1
Abstract:
The present invention relates to a boat lift device for lifting a ship, such as a motorboat, a utility boat, a prefabricated rubber boat, a shipping boat, a cruise yacht, or a dinghy yacht, above the surface or for floating the same on the surface and, more particularly, to a boat lift device operated by a hydraulic cylinder, air, water pressure, a worm gear, or a rotor. A device for floating a ship or lifting an immersed boat according to the present invention is configured such that, when the ship is fully lifted above the surface, the lower portion of a lifting assembly is not immersed below the surface, and load transfer portions of buoyancy tanks are not abraded, thereby ensuring excellent durability and natural, smooth operation of the buoyancy tanks. In addition, the device for floating a ship or lifting an immersed boat according to the present invention has a reduced radius of rotation of the buoyancy tanks, or the lifting assembly ascends/descends vertically in an elevator type while the buoyancy tanks are floating on water, thereby improving the space usability of the place at which the boat lift device is installed, and making the locking means and the lifting assembly simple. Furthermore, the device for floating a ship or lifting an immersed boat according to the present invention guarantees that, even when a ship is lifted or lowered on a predetermined rock face or at a fixed marina mooring facility, the interval between the buoyancy tanks does not increase at all, thereby substantially improving space usability.
