FIELD: transport.
SUBSTANCE: invention relates to machine building, particularly, to lift-and-carry machines, particularly, to jib manipulator drives. Proposed drive comprises hydraulic cylinder, double-arm lever and tie-rod coupled with jib. Hydraulic cylinder and levers are intercrossed to make closed system while double-arm lever interacts with hydraulic cylinder in oblique angle zone to increase actuator turn angle. Rotational axes of hydraulic cylinder case and double-arm lever are located on one straight line and equidistant from jib turn axis.
EFFECT: optimum configuration of jib turn drive, decreased dynamic loads.
