The invention discloses a derail-prevention and rail-gnawing-prevention device for the operation of a cart and a trolley of a crane. By virtue of the derail-prevention and rail-gnawing-prevention device, rail gnawing and derail phenomena of operation mechanisms of the cart and the trolley of the crane are avoided, and the abrasion of wheel edges of wheels, and cart and trolley rails can be avoided in an operation process of a wheel group; the stability is enhanced when the crane is operated; and the friction resistance of an operation side of the crane is reduced, and the friction noises of the wheels and the rails are reduced.
