MECHANISM OF ROTATION OF THE CRANE

摘要

Invention concerns self-propelled jig, including truck cranes and it is intended for rotating coupling of the supporting frame of crane with its pivoting floor. The reduction of prime cost of the mechanism of rotation of the crane is the technical task of the invention, for which the drum 5 for rope17 is motionlessly connected or executed in the form of a single whole with external ring, the shaft 13 of the drive 12 of pivoting mechanism mounted on the platform with possibility of tension of the rope 17 between drum 5 and pulley 14, is motionlessly connected with the pulley for rotation around the drum.
