The invention discloses an anti-swing device of a crane. The device comprises a supporting foot stand, a fixed bottom plate, a balance bottom plate, a fixed supporting arm, a telescopic arm and a siderotating foot rod. Butt joint clamping seats are fixedly mounted on the outer surfaces of the two sides of the fixed bottom plate. The supporting foot stand is fixedly mounted at the front part of the fixed bottom plate. The side rotating foot rod is movably installed on one side of the supporting foot stand. The outer surface of the side rotating foot rod is movably sleeved by a side rotating clamping rod. Inclined supporting feet are movably installed at the bottom of the side rotating foot rod. Spherical clamping grooves are formed in the middles of the inner sides of the inclined supporting feet. A ball clamping pin is fixedly installed on the outer surface of the lower end of the side rotating foot rod. The upper portion, fixedly close to the ball clamping pin, of the outer surface of the side rotating foot rod is movably sleeved by a fixing clamping sleeve. According to the crane anti-swing device, the crane anti-swing device is provided with an inclination angle adjusting structure, so that the stability of the crane anti-swing device is improved; meanwhile, the crane anti-swing device is provided with an inclination auxiliary fixing structure, so that the fixing operationis firmer, and the anti-swing effect of the crane anti-swing device is improved.
