    to supply an inventive otnost-gts to the lift-trapport1-gu construction, namely, to the two-second control systems for the two-sec and cnc and d But about cars,
    The purpose of the invention is convenience branded.
    Fig, i depicts the machine G rocker; n lifting machine with yoke Tog-; women - overhang; fig, lift mz-bus with work "
    The control unit of a two-section hoist of a lifting machine contains a yoke 15 fixed with a FJOSMOKHOC-turn of a turn on section 2 of an arrow, hinged but fixed on a turntable 3 of a self-propelled lifting machine, the first hydraulic jig 4 is hinged at one end on a turntable 3 s1 trip. The first hoisting machine and the other end of the yoke 1 is the second hydraulic cylinder 5, pivotally connected at one end with the section 2 firing on the platform, with the other end at the other section 6 of the boom, on which the hinge fixed actuator 7 ,, and a constant of dlrlne rods in 8, hinged one hydrochloric Quotidienne 1 ,, on the yoke and the other end - to form 3 pla
    Point 9 of the mounting of the yoke 1 on the boom section 2, fastened to the taper 3, is located at points 10 to 11 of the fastening, respectively, of the first Hydro 7G; 1 Ndra 4 and fixed along the length of the P-8 8 Lift 3 of the lifting machine, with the gtu points 13 and 14 of the corresponding mounting of the boom section 2 and the first hydraulic rig 4 on the platform 3 and wiring line 15 of the junction m7 {f, ui yi kutymk with the fixed points

Point of fastening 12 constant along the length of the rod 8 on platform 3 is shifted towards the point 13 of the fastening fixed on the platform of section 2 boom, and point 2 of the mounting of the rocker arm 1 on the section 2 of the boom mounted on the platform 3 towards the side of 10 securing the first hydraulic cylinder 4 on the rocker arm 1.

    The crust of the layer 1 knife is provided with the longitudinal section of the boom section 2 above its point of attachment 9 by the protrusion 17, from which one end of the third hydroelectric core 18 is hingedly connected, the other end of which is fixed to the working tool 7 (figure 2); The points 19 and 20 of attachment of the third hydraulic cylinder and points 21 and 22 of attachment of another boom section 6 to the working tool and on the boom section 2 connected to the platform are located to form a hinged four-link.
    The device works as follows
    We give the work gshdёmnoy machines on the measures. From the position of boom sections 2,, 6 (FIG. 3), it can be seen that the maximum length of the third hydraulic cylinder 18 {; it is so large that with the smallest length of the hydraulic cylinder 4 and the greatest length of the hydraulic cylinder 5, the working body 7 in its final position rotates against the stop 23 Shooting section 6.
    In accordance with this, the minimum of the hydraulic cylinders 18 with the shortest length of the hydraulic cylinder 4 varying in length and the greatest length of the extension of the hydraulic cylinder 5 leads to the support of the working body 7 with an emphasis at itoBopoTe ,. The received coordinate system in the center of the body of the working body 7 shifts with a constant angle relative to the coordinate-parallel system relative to the point 13 of the fixed axis of rotation of the boom when the working length of the hydraulic cylinder 4 changes to kg in certain position of rotation of the working body 7. FIG. . 4 explains the work of the working body 7. If you present the coordinate system in the center of the body of the working unit and when it is jiocT - it depends on the coordinate system on the boom axis, you can see that when the working length of the hydraulic cylinder 5 changes, the working body I o 7 tracks along line 24, namely, at the same angle of both coordinate systems to each other and limited when turned by the stop 23. The coordinate system in the center of gravity of the working body when the working length of the hydraulic cylinder 4 only changes maintains its angle relative to the coordinate system atm at the boom axis and constant working body follows the path shown by the curve 25. The length of the hydraulic cylinder 18 remains constant.
