Abstract
Une plate-forme de travail (48) est supportée par un manchon (46) qui peut se déplacer le long d'une tour (40) comportant une pluralité de barreaux (45) équidistants en direction verticale. Selon l'invention, le système élévateur (50) comprend deux vérins hydrauliques (52), montés rotatifs sur le manchon (46) et comportant des crochets (58) à l'extrémité de la tige (52a) de piston. Les vérins (52), actionnés de façon à effectuer un déplacement vers le haut et vers le bas simultané, mais dans des directions alternées, portent successivement sur les différents barreaux (45) de la tour (40) et s'y accrochent, de façon à faire monter le manchon (46) le long de la tour (40). Quand, durant le déplacement vers le haut, un barreau (45) se retrouve sur le trajet d'un crochet (58), ce dernier pivote vers l'arrière de façon à libérer le barreau (45), puis est remis en place par des ressorts (66). La manoeuvre d'abaissement du manchon (46) se fait de manière similaire à la manoeuvre d'élévation, mais l'opérateur doit déverrouiller des leviers de blocage (82) afin de permettre aux ressorts (86) de faire pivoter les crochets (58), de façon à les faire passer dans une position de libération des barreaux durant la rétraction de la tige (52a) de piston du vérin correspondante, ce qui permet au crochet (58) de libérer les barreaux (45).
