The deviation rectifying device comprises a controller, a first deviation rectifying assembly and a second deviation rectifying assembly, the first deviation rectifying assembly comprises a first frequency converter, a first deviation rectifying driving mechanism and a first permanent magnet generator, and the second deviation rectifying assembly comprises a second frequency converter, a second deviation rectifying driving mechanism and a second permanent magnet generator; rotors of the first permanent magnet generator and the second permanent magnet generator are connected with wheels on the two sides of the traveling crane through linkage mechanisms respectively. The input ends of the first frequency converter and the second frequency converter are connected with the controller, and the output end of the first frequency converter and the output end of the second frequency converter are connected with the first deviation rectifying driving mechanism and the second deviation rectifying driving mechanism respectively. The controller receives output voltage values of the first permanent magnet generator and the second permanent magnet generator and controls the first deviation rectifying driving mechanism and the second deviation rectifying driving mechanism to drive the wheels to accelerate or decelerate through the first frequency converter and the second frequency converter respectively. The deviation rectifying device for the travelling crane is low in cost, more stable and more reliable.
