VERTICAL SLIPWAY FOR LOWERING AND LIFTING SHIPS Russian patent published in 2023 - IPC B63C3/06 E02C5/00 

FIELD: shipbuilding; ship repair.

SUBSTANCE: invention is related in particular to devices designed for lowering built ships, for lifting and lowering ships in order to repair them. A vertical-type slipway for lowering and lifting vessels is proposed, including a lifting platform installed in the dock chamber and a system of slipway lifting winches with pulley blocks, the lifting platform is equipped with side wheels oppositely mounted on it, interacting with vertical guides on the walls of the dock chamber, and lifting winches are installed on each side of the dock chamber in niches made in the walls of the dock chamber below the level of the slipway, while the lower rope pulley blocks are fixed on the lifting platform in places that ensure position of the upper surface of the lifting platform when it is raised at the level of the slipway, in addition, on the transverse tracks of the lifting platform there are slipway carts with a block-keel set, which ensures reliable and safe support and strengthening of the vessel on them during ascent or descent and transverse movement to the slipway or from the slipway to the lifting platform, for which the slipway is equipped with a set of transitional rail inserts, connecting the transverse tracks on the lifting platform with the transverse tracks on the slipway.

EFFECT: ensuring the lifting of a vessel on a lifting platform to the level of the slipway, its unhindered transverse movement to the slipway and its maintenance in more convenient and safe conditions.
