FIELD: cargo hoisting equipment, mainly for agricultural machine engineering. ^ SUBSTANCE: manipulator includes flat base with brackets of hinged unit and telescopic supports; supporting-rotary column mounted with possibility of rotation around axis of base and carrying jointly mounted in it: boom, handle and cargo gripping hook; powered hydraulic cylinder mounted in pairs and used for controlling boom and handle; additional hydraulic cylinders of mechanism for rotating supporting-rotary column. Cargo gripping hook is joined with end of handle through flexible movable ropes. First end of first rope forms safety loop and it is arranged with use of locking member in end of rod of powered hydraulic cylinder whose base is mounted in bracket on other end of handle. Said safety loop embraces powered hydraulic cylinder and restricts limit motion value of rod out of cavity of powered hydraulic cylinder. Second end of first rope is mounted on axle in bracket on end of handle. In arc-shaped portion of first rope block with H-shaped bracket is arranged; in lower pivot of said block locking member of first end of second rope is arranged and its second end is mounted similarly on end of handle. In arc-shaped portion of second rope block with H-shaped bracket is mounted; in lower part of said block traverse bar with cargo gripping hook is arranged. ^ EFFECT: enhanced operational efficiency of manipulator. ^ 9 cl, 8 dwg |
