The step support (17) or plate support comprises a rear crossmember (22) and a front crossmember (24) which together form a plane (E3) for receiving the tread element (9). There are two outer step cheeks (20.1, 20.2), wherein one of the step cheeks (20.1) is arranged on the right and one of the step cheeks (20.2) is arranged on the left, substantially perpendicular with respect to the crossmembers (22, 24). The two crossmembers (22, 24) are manufactured from deep-drawing sheet metal and are welded or joined or riveted or screwed or adhesively bonded or clinched to the step cheeks (20.1, 20.2) or plate cheeks to form a load-bearing frame. The height (H2) of the crossmembers (22, 24) at its ends is smaller than the height (H3) of the crossmembers (22, 24) in the centre, with the result that the crossmembers (22, 24) have a curved shape.
La présente invention concerne une structure de marche (17) ou une structure de palette comprenant une traverse arrière (22) et une traverse avant (24) qui définissent ensemble un plan (E3) conçu pour recevoir l'élément de marche (9). La structure comprend également deux limons de marche extérieurs (20.1, 20.2), l'un de ces limons de marche (20.1) est placé à droite et l'autre limon de marche (20.2) est placé à gauche, de manière sensiblement perpendiculaire aux traverses (22, 24). Les deux traverses (22, 24) sont fabriquées en tôle à emboutir et sont soudées, raccordées, rivetées, vissées, collées ou encliquetées avec les limons de marche (20.1, 20.2) ou les limons de palette afin de former un bâti porteur. La hauteur (H2) des traverses (22, 24) à leurs extrémités est supérieure à la hauteur (H3) des traverses (22, 24) en leur centre, de manière que les traverses (22, 24) présentent une forme convexe.
