The invention discloses a multi-angle adjusting device and method for a lifting hanging beam of a large loading and unloading bridge crane. The multi-angle adjusting device comprises a base, a lever mechanism, a stress application mechanism, a supporting mechanism and a hydraulic electric control mechanism, the lever mechanism is connected with the lifting hook; the force applying mechanism is used for applying hydraulic force to the lever mechanism; the supporting mechanism is used for supporting the base; and the hydraulic electric control mechanism is used for controlling the operation of the stress application mechanism and the supporting mechanism. Effective pulling force is applied to the replaced steel wire ropes, so that the error value of the two lifting steel wire ropes is accurately displayed.
