METHOD FOR LIFTING VESSEL ONTO COASTAL SLIPWAY Russian patent published in 2021 - IPC B63C3/04 B63C3/00 E02C3/00 

FIELD: shipbuilding.

SUBSTANCE: invention relates to shipbuilding and ship repair, and in particular to technologies and tools used to lift ships from the water area to the coastal slipway. Rail ship-carrying tracks are made of two sections - an inclined section to the water area, on which, before the vessel is lifted, a shoal trolley with horizontal rail ship tracks is placed under the platform for placement on its keel blocks of the vessel, and a horizontal section of rail ship tracks on the coastal slip for moving the platform with the ship, at the same time, before lifting the vessel, a shoal trolley with a platform placed on it is installed in the water area, after which the vessel to be lifted is started and installed on the platform, then, by means of the cable-block system, the jamb trolley with the platform and the ship is moved until the ship-carrying rails on the jumbo bogie are coupled with the rail ship-carrying tracks on the horizontal section, after which the platform with the vessel is moved by means of the cable-block system along the horizontal section of the rail ship tracks on the coastal slipway. The cable-block system is performed with one winch and two drums, which are installed on one shaft, and ensure their interaction by means of a cam clutch, the bypass block of the cable-block system is installed on a jamb trolley.

EFFECT: invention provides an increase in the reliability and efficiency of the method for lifting a vessel from the water area to the coastal slipway, simplifying the design of the launching device.
