MANIPULATOR CRANE Russian patent published in 2024 - IPC B66C23/44 

FIELD: transportation.

SUBSTANCE: invention relates to lifting-and-transport machines for handling and other operations performed by mobile lifting-and-transport units with limited carrying capacity. Manipulator crane comprises a base made in the form of a triangular truss, on which a hinged-rod boom, made in the form of hinged-rod trusses, is hingedly mounted, hinged-rod trusses, which make up the boom structure, have the form of rod triangles with flat trusses in the transverse direction. Two power hydraulic cylinders of the triangular truss of the base of the hinged-rod boom form an angle with each other εvariable depending on the size of the structure, and by their rods the power hydraulic cylinders converge in a common spatial hinge, which is attached by means of trunnions to the front upper bar of the U-shaped truss. By their bases the power hydraulic cylinders are attached by means of rotary supports to the rigid crossbar of the base of the triangular truss. Telescopic rods are hinged by one end to the same rigid crossbar of the base of the triangular truss. Other end of the telescopic rods is hinged to the rear bar of the U-shaped truss. Hinged-rod boom is made in the form of triangular connections from rods, and in the base of two triangular connections there are two power hydraulic cylinders, and sides of these triangular connections are rods and power hydraulic cylinders of triangular truss. Bases of two parallel power cylinders are fixed in rotary supports, which are located on front upper bar of U-shaped truss, and rods of two power hydraulic cylinders parallel to each other are hinged to crossbar of base of flat truss of boom. Bars making up the U-shaped truss have thickened dimensions, and the U-shaped truss structure rests on paired supports, which in turn are rigidly connected to the vehicle. Base of power hydraulic cylinder is hinged on top crossbar of flat truss of hinged-rod boom. Rod of power hydraulic cylinder is hinged to the top of lever made in the form of rigid rod triangle. Base of the lever in the form of a rigid rod triangle is a crossbar, which is also the end of the flat truss of the hinge-rod boom. Lever in the form of a rigid rod triangle is connected to the load gripper through the crossbar.

EFFECT: provides for optimum distribution of loads on elements of hinged-rod boom and sufficient functional capabilities of crane-manipulator.
