An apparatus (20) for induction heat treating, restraint quenching, and straightening an associated carbon steel truck structural member (30), having a web (32) and at least one flange (34) substantially perpendicular thereto, comprises a heat treating apparatus (22) for induction heating and restraint quenching the associated structural member (30). The heat treating apparatus (22) is operatively connected to a cooling conveyor (50). The cooling conveyor (50) is adapted for receiving the associated structural member (30) from the heat treating apparatus (22). A testing apparatus (24) is included for hardness testing the heat treated associated structural member. The testing apparatus (24) is adapted for receiving the associated structural member (30) from the cooling conveyor (52). A conveyor (54) is adapted for receiving the associated structural member (30) from the testing apparatus (24). A roller straightener (26) is operatively connected to the conveyor (54). The roller straightener (26) is adapted for receiving the associated structural member (30) from the conveyor (54). The roller straightener (26) has at least three rolls (64b, 64c, 64d) proximately located to one another for operatively engaging the associated structural member (30) between the rolls. The roller straightener (26) further includes an apparatus (78) for adjusting the position of at least one of the rolls (64) along a first axis.

Un appareil (20) de traitement à chaud par induction, de trempe en contrainte et de dressage d'un élément structurel associé (30) de camion en acier au carbone, présentant une âme (32) ainsi qu'au moins une aile (34) sensiblement perpendiculaire à cette dernière, comprend un appareil (22) de traitement à chaud destiné au chauffage par induction et à la trempe en contrainte de l'élément structurel associé (30). L'appareil (22) de traitement à chaud est connecté fonctionnellement à un convoyeur de refroidissement (50). Le convoyeur de refroidissement (50) est adapté pour recevoir l'élément structurel associé (30) de l'appareil de traitement à chaud (22). On a prévu un appareil d'essai (24) destiné à tester la dureté de l'élément structurel associé traité à chaud. L'appareil d'essai (24) est adapté pour recevoir l'élément structurel associé (30) du convoyeur de refroidissement (52). Un convoyeur (54) est apte à recevoir l'élément structurel associé (30) de l'appareil d'essai (24). Un dresseur (26) à rouleaux est relié fonctionnellement au convoyeur (54). Le dresseur (26) à rouleaux est apte à recevoir l'élément structurel associé (30) du convoyeur (54). Le dresseur (26) à rouleaux présente au moins trois rouleaux (64b, 64c, 64d) situés à proximité les uns des autres afin de venir en contact fonctionnel avec l'élément structurel associé (30) passant entre les rouleaux. Le dresseur (26) à rouleaux comprend également un appareil (78) destiné à ajuster la position d'au moins un des rouleaux (64) le long d'un premier axe.
