<p>AN ARRANGEMENT FOR BENCHES FOR MEASURING AND STRAIGHTENING VEHICLES Apparatus for measuring and checking vehicle bodies comprises a bench with a co-acting measuring bridge. In a known way, a vehicle body can be clamped over the bench and selected points on the body can be located from underneath by means of slides with pointed measuring pins which form part of a known measuring bridge, for the accurate determination of the relative location of points on the body. An overhead measuring stand enables points located high up on the body to be measured from above in order to obtain reliable measurement values. By means of a special orientation device the position of the normal measuring bridge relative to the overhead measuring stand is determined so that both give corresponding measurement values. The measuring stand is preferably equipped with a telescopically extensible locating pin which is positioned in the plane of symmetry of the body and by means of which the symmetrical position of various points on the body can be checked.</p> |
