Abstract

Cette invention concerne les grues télescopiques à montage rapide. Pour pouvoir surélever une grue de ce type, il est prévu des moyens associés au pied de mât et permettant, de façon en son connue, le télescopage du mât pour son relevage et sa descente, mais aussi le déplacement, par rapport à ce mât amené en appui sur le sol, de l'ensemble inférieur de la grue, comprenant le châssis, la plate-forme tournante et le pied de mat. Ceci permet de soulever cet ensemble inférieur par rapport au mât intérieur en appui sur le sol et d'engager un bâti de support tel qu'un pylône de grue à tour sous cet ensemble ainsi soulevé. Le mât intérieur de la grue peut ensuite être télescopé de la façon classique. Cet agencement supprime la limitation de hauteur de travail des grues repliables ou à montage rapide qui réduisait jusqu'ici leurs applications.
