SALVAGE SYSTEM Russian patent published in 2014 - IPC B63C7/04 B63C7/06 

FIELD: transport.

SUBSTANCE: salvage system relates to devices for lifting sunken objects, predominantly wooden vessels. The system contains floating facility with hoisting mechanism, lift-and-carry transfer mechanism, ballast reservoirs, guidance facility, sunken object slinging device, mechanism for ground erosion and tunnels formation, lifting pontoons installed between floating facility and lift-and-carry transfer mechanism at depth equal to sinking depth of hook of hoisting mechanism main lift. Lift-and-carry transfer mechanism is composed of interconnected separate blocks made in the form of horizontal frame at edges of which vertical sections with ballast reservoirs at its top part and horizontal supports at its bottom part are installed. On top of the units longitudinal and transversal reinforcing members are installed on which lugs for towing the lift-and-carry transfer mechanism and lifting the device, pontoon slinging. Vertical sections of utmost blocks of the device are interconnected, and bottoms of ballast reservoirs are bevelled. Mechanism for ground erosion and tunnels formation is made as platform located on load-carrying beams and is provided with jetless nozzle and assembly for carrying link attachment.

EFFECT: simplification of system main assemblies design, system functionality enhancement.
