The invention provides derailing prevention wheels, a crane, a trolley of the crane and a cart of the crane. The phenomenon of derailment of the crane, the trolley of the crane and the cart of the crane caused when wheels run aslant is prevented. The crane, the trolley of the crane and the cart of the crane comprise the derailing prevention wheels. Each derailing prevention wheel comprises a wheel tread and a rim; an annular groove with an arc section is formed in the combination position of the wheel tread and the rim; the phenomenon that the derailing prevention wheels are ejected by tracks when running aslant is avoided, and therefore the phenomenon of derailment of the crane, the trolley of the crane and the cart of the crane is prevented effectively. Meanwhile, the sections of the annular grooves are in the arc shape, stress concentration can be effectively avoided, and force of friction between the derailing prevention wheels and guide rails is reduced.
