Abstract

La présente invention concerne un ensemble plate-forme auto-élévateur, comprenant au moins un mât (3, 5, 113) le long duquel une plate-forme (13) peut être déplacée vers le haut ou vers le bas. Cet ensemble plate-forme comprend a) un élément de base (9) comprenant une plaque de support (25) qui est connectée à un vérin (27) et à plusieurs bras de stabilisation (33, 37) comprenant un système de réglage en hauteur, b) des sections de mât modulaires (7), qui sont constituées de sections rectangulaires présentant des ouvertures (63) ménagées pour former des niveaux et de barres (55) permettant à des sections adjacentes d'être boulonnées ensemble, c) un mécanisme de levage à vérin hydraulique (73, 83, 84) comprenant des crochets (77, 79, 81) qui s'engagent dans des niveaux sur le mât, afin d'élever ou de descendre la plate-forme, d) une gaine à protection en plastique (17, 19), qui est située sur la plate-forme et glisse contre le mât, ainsi que e) une plate-forme modulaire, qui peut être allongée ou élargie par ajout de modules supplémentaires (101, 103).
