FIELD: lifting-and-conveying equipment. ^ SUBSTANCE: invention relates to special-purpose lifting-and-conveying facilities. Support hydraulic device comprises four two-rod hydraulic cylinders interjointed by extension compensator. Lower rods of aforesaid hydraulic cylinders make outriggers. Proposed device comprises also mechanism of two-plane top rotary platform inclination mechanism hinged to hydraulic cylinder upper rods. Top rotary platform supports jib with counterweight. Axis of the latter is oriented vertically with the help of servo system consisting of lever system and to rotary platforms, i.e. inclined top and horizontal bottom platforms. Piston chambers of opposite top rods are communicated, in pairs, via pump, hydraulic control system and servo gate valves. Aforesaid jib is driven by lifting-lowering opposite top rods of hydraulic cylinders hinged to fixed part of the platform. Working fluid flows in hydraulic system lines can be microprocessor-controlled. ^ EFFECT: perfected design. ^ 6 dwg |
