The invention relates to a swing mechanism for a slewing crane. The swing mechanism comprises a pedestal which is provided with a stationary shaft arranged vertically, and a circular rotary table which is disposed on the stationary shaft. The axis of the rotary table coincides with the axis of the stationary shaft, and the rotary table is in axial fixed and radial running fit with the stationary shaft. The bottom of the rotary table is provided with wheels uniformly along the circumference of the bottom of the rotary table, and an annular guide rail which makes the wheels roll along the guide rail when the rotary table rotates is disposed on the pedestal. The stationary shaft of the swing mechanism is difficult to damage, and the service life of the swing mechanism is long.
