A straightening arrangement for straightening a chassis frame, having a plurality of bridges (11). Each bridge has a horizontal beam (12) and a vertical beam (13) whose lower end is fixed to the horizontal beam, a floor anchorage which detachably fastens the bridge to the floor, a device (15) arranged horizontally on the beam construction, and a chain attachment fitting (18). The bridge is locked in at least two directions, perpendicular to one another and also to the chassis frame. The horizontal device is arranged, in the straightening of a chassis frame which is bent in the lateral direction, to apply a horizontally directed force. The chain attachment fitting is arranged in the straightening of a chassis frame, which is bent in the vertical direction or is crooked, to secure a chain that is attached to the chassis frame.
