FIELD: cargo hoisting equipment, mainly for agricultural machine engineering. ^ SUBSTANCE: manipulator includes flat base with brackets of suspended member and with telescopic supports; supporting-rotary column mounted with possibility of rotation around base axis and having boom, handle and cargo gripping hook, all jointly mounted in it; mounted in pairs powered hydraulic cylinders for controlling said boom and handle; additional hydraulic cylinders of mechanism for rotating said supporting-rotary column. Cargo gripping hook is joined with end of handle by means of rope coupled with end of handle through pair of blocks. Upper end of rope is fixed by means of locking member on end of rod of powered hydraulic cylinder. Loop of upper end of rope embraces powered hydraulic cylinder and it restricts limit extension value of rod out of cavity of said cylinder. Loop of lower end of rope is secured by means of locking member; loop embraces block mounted with possibility of rocking motion on axle in H-shaped bracket over traverse bar of cargo gripping hook. ^ EFFECT: enhanced operational reliability of manipulator at loading-unloading operations. ^ 6 cl, 4 dwg |
