HOIST-LOWER UNIT Russian patent published in 1998 - IPC

FIELD: shipbuilding. SUBSTANCE: hoist-lower unit includes cargo winch mounted on board ship and auxiliary winch mounted on object to be lowered, as well as first control unit whose input is connected to first setter and outputs is connected to control input of cargo winch and second control unit whose first input is connected to second setter and output connected to control input of auxiliary winch drive. Winches are interconnected by means of flexible coupling which consists of variable-depth sonar cable and rope whose one end is rove on drum of auxiliary winch and other end is secured to variable-depth sonar cable whose one end is brought onto the drum of cargo winch and other end is connected with body of object to be lowered, thus excluding entanglement of flexible coupling and enhancing stabilization of depth of submergence. EFFECT: avoidance of entanglement of flexible coupling and enhanced stabilization of depth of submergence. 3 cl, 1 dwg
