The invention relates to arrangements for straightening damaged vehicle bodies by means of straightening devices which pull and/or press, which is of the kind having a transportable alignment bar equipped with retractable wheels, said alignment bar during a straightening operation being lowered to rest on a floor joist and being fastened in a conventional way to this joist with bolt connections or the like, said alignment bar consisting of a baseplate and at least two upright wall elements attached thereto, which together form a substantialy U-shaped profile with a longitudinally extending guideway for at least one straightening assembly displaceably mounted in or on the alignment bar and comprising at least one upright beam for attachment of the straightening devices. The invention is characterised in that the straightening assembly is constructed as a rolling carriage which is displaceably mounted in or on at least two parallel guideways formed in or on the wall elements, and in that the rolling carriage is designed to carry out longitudinal displacement movements in both directions by means of a servo-controlled operating device attached to the alignment bar and having a line of action extending longitudinally between the said wall elements.

Arrangement for straightening damaged vehicle bodies

The invention relates to a straightening jig for vehicle bodies, particularly for the cabs of trucks, of the kind comprising a stand for fastening to a floor or other foundation, and being equipped with a number of bearing fixings in which a number of bearing components on a vehicle body are intended to fit and be fixed when the vehicle body is located on the jig. The invention is characterized in that the stand is provided with guideways for at least one alignment bar which is displaceably arranged in the jig and which extends in the longitudinal direction of the jig, in that the alignment bar is provided with at least one bearing fixing in which a bearing component on the vehicle body is fitted when the vehicle body is located in the jig, in that the alignment bar is arranged so that it can carry out displacement movements in the guideways both in the longitudinal and transverse directions of the alignment bar, preferably with the aid of servo-controlled operating devices, and in that the relative position of the alignment bar in the stand can be locationally fixed when the alignment bar is moved into a given position for the bearing components of the vehicle body in the stand of the jig.
