A motor vehicle bodywork parts painting inspection station, the inspection station comprising an optical measuring apparatus, wherein the measuring apparatus is mounted on a tracker robot (6, 7) which moves the measuring apparatus along the path of a motor vehicle bodywork part that moves, i.e. in motion, while measurement is taking place, and wherein the inspection station includes a conveyor for motor vehicle bodywork parts, characterised by means for attenuating vibration (31, 42-44, 55, 61) of the moving parts, said conveyor being configured such that: - the parts being conveyed by poles carried at their bases by moving wheeled carriages, in which a slideway is provided along the paint inspection station for receiving the free top ends of the poles and for guiding them parallel to the path of the carriages so as to prevent them from rocking transversely with rolling motion, or - the parts being conveyed by poles carried at their bases by wheeled carriages, in which holding members for holding the free top ends of the poles are arranged above the carriages, and are driven parallel to the carriages so as to accompany the travel of the poles, which poles are thus held at both top and bottom ends, and are prevented from vibrating, or - the parts being conveyed wheeled carriages running on by rails, in which the rails are covered in a layer of a not very adherent material such as PTFE over a length that corresponds to that of the inspection station, or - conveying being performed by wheeled carriages running on a rail made of a plurality of bars (51, 52, 53, 54) in end-to-end abutment, in which a layer of a material suitable for constituting a running surface for wheels covers the bars (51, 52, 53, 54) and also covers gap zones between them over the entire length of the inspection station so that the carriages going past the inspection station are not subjected to vibration due to crossing a gap zone between two consecutive bars (51, 52, 53, 54), or - conveying being performed by wheeled carriages, whereby raised rails are provided for raising the carriages in the region of the inspection station so that during inspection the carriages cease to be carried by the wheels that have carried them through the painting line. - the parts being conveyed by poles carried at their bases by moving wheeled carriages, in which a slideway is provided along the paint inspection station for receiving the free top ends of the poles and for guiding them parallel to the path of the carriages so as to prevent them from rocking transversely with rolling motion, or - the parts being conveyed by poles carried at their bases by wheeled carriages, in which holding members for holding the free top ends of the poles are arranged above the carriages, and are driven parallel to the carriages so as to accompany the travel of the poles, which poles are thus held at both top and bottom ends, and are prevented from vibrating, or - the parts being conveyed wheeled carriages running on by rails, in which the rails are covered in a layer of a not very adherent material such as PTFE over a length that corresponds to that of the inspection station, or - conveying being performed by wheeled carriages running on a rail made of a plurality of bars (51, 52, 53, 54) in end-to-end abutment, in which a layer of a material suitable for constituting a running surface for wheels covers the bars (51, 52, 53, 54) and also covers gap zones between them over the entire length of the inspection station so that the carriages going past the inspection station are not subjected to vibration due to crossing a gap zone between two consecutive bars (51, 52, 53, 54), or - conveying being performed by wheeled carriages, whereby raised rails are provided for raising the carriages in the region of the inspection station so that during inspection the carriages cease to be carried by the wheels that have carried them through the painting line.
