FIELD: ship raising technique. SUBSTANCE: ship raising complex includes upper and lower ropes, positive buoyancy marker connected with upper part of rope and two gripping devices fitted on this rope for motion towards ship; gripping device are connected with load-bearing rope of cargo-hoisting gear. Each gripping device has two pulleys fitted on parallel axles; pulleys are engageable with axles by means of overrunning clutch. Marker rope embraces these pulleys by figure-eight. Mass of upper portion of rope corresponds to positive buoyancy of marker and its length is no less than maximum depth of area of operation of ship. Strength of lower portion of rope corresponds to rated load in raising the ship. EFFECT: simplified construction. 3 dwg
