The invention discloses an assembling method of a crane slewing device. The slewing device comprises a rotary table main structure, a rotary table propeller strut, a rotary table flange, a base flange, a base and a sectional slewing bearing. The assembling method comprises the following steps: 1, connecting the rotary table main structure with the rotary table flange; 2, a leveling tool is arranged, and the rotary table flange is adjusted to be parallel to the horizontal plane; 3, machining the mounting surface of the turntable flange until the planeness form and location tolerance of the mounting surface meets the mounting requirement; 4, assembling the sectional type slewing bearing to the rotary table flange; 5, integrally overturning the rotary table main structure, the rotary table flange and the sectional type slewing bearing, and welding a rotary table propeller strut on the rotary table flange; 6, connecting the base flange with the base; and 7, the rotary table main structure, the rotary table propeller strut, the rotary table flange and the sectional type slewing bearing are integrally assembled on the base flange, and assembling work is completed. According to the design, manpower and material resources are saved, and production efficiency can be improved.
