FIELD: transportation.
SUBSTANCE: invention relates to hoisting-and-conveying machines for moving suspended loads in vertical plane and can be used in automatic lines, robot-manipulators and process plants for immersion and removal of long pipes from vertical boreholes. Lifting manipulator comprises articulated device for transfer of suspension with portable load, made in form of four-link rhomb shaped kinematic chain of hinged rhombus. Hinge rhombus is kinematically connected to base by means of double cylindrical hinges and pivoting levers interconnected by means of driven movable hydraulic cylinder.
EFFECT: invention provides 2-fold increase in working area of suspended cargo movement, reduction of hydraulic power input in 1_5-2 times required for cargo lifting and simplification of lifting manipulator design at reduction of labor intensity of its assemblies manufacturing and assembly.
