Abstract

L'invention concerne un dispositif de redressement de carrosserie (10) destiné à redresser la carrosserie d'un véhicule déformée lors d'un accident de la route ou similaire. Ledit dispositif est composé d'une structure (11) pouvant recevoir l'ensemble de la carrosserie, d'un dispositif de levage de carrosserie (12) disposé dans la structure, d'un dispositif de maintien de la carrosserie (13) destiné à arrimer de manière amovible la carrosserie suspendue, de roues (14, 15) disposées sur quatre positions de la structure (11) (avant/arrière et gauche/droite), et de dispositifs de compression destinés à comprimer la carrosserie, logés dans la structure (11), et constitués d'une pluralité de cylindres supérieurs (16) et de cylindres suspendus (17) montés sur une unité supérieure, d'une pluralité de cylindres latéraux (18) montés sur des unités latérales gauche et droite, et d'une pluralité de cylindres inférieurs (19) montés sur une surface inférieure. L'invention concerne également un procédé de redressement de la carrosserie consistant à redresser des parties de la carrosserie logée dans la structure, par compression au moyen d'une pluralité de dispositifs de compression. Ledit procédé permet de s'affranchir de l'arrimage ou de l'extraction de la carrosserie par des éléments et des chaînes de support correspondants, et garantit un travail de redressement rapide et sûr. La compression et le redressement directs de parties déformées provoquent une détente très faible et permet même aux carrossiers même inexpérimentés de redresser précisément la carrosserie sans maîtrise de haut niveau. Par ailleurs, il est possible de réaliser des gains de place substantiels comme les travaux de redressement peuvent être effectués uniquement à l'intérieur de la carrosserie.
