1. An aligning device for aligning a guide rail of an elevator system, wherein the guide rail is held on a shaft wall of an elevator shaft and is displaceable in at least two horizontal directions oriented crosswise with respect to one another before a final fixation of the guide rail, the aligning device comprising:
a detection device adapted to automatically detect a position deviation of the guide rail from a predetermined nominal position in the elevator shaft; and
a hammer mill adapted to automatically hammer the guide rail in response to the detected position deviation toward the nominal position by exerting pulse-like strikes in at least one of the at least two horizontal directions.
