FIELD: transportation.
SUBSTANCE: complex for lifting of sunk object comprises basic vessel-catamaran, lifting mechanism installed on it with steel wire rope, cross-beam with hauling device. On cross-beam with hauling device, symmetrically to its longitudinal axis, unit is fixed from vertically oriented rocket engines with controlled pulling force and with the possibility to install rocket movers on both sides of its longitudinal axis. Pulling force of rocket movers is calculated for break-off of sunk object from basin bottom. Hauling device is arranged in the form of levers hingedly installed on cross-beam with the possibility of independent rotation of all levers relative to their hinges. In initial position levers in vertical plane are oriented at the sharp angle to vertical line and are kinematically connected by means of power cylinders with stems with cross-beam. Besides lower edges of levers prior to gripping of sunk object are arranged at the level that exceeds position of its bottom by value of sunk object possible submersion in bottom mud.
EFFECT: reduced labour-intensiveness of salvage operation.
