Abstract
L'invention concerne une grue repliable perfectionnée. La grue repliable, destinée aux chantiers de construction, se compose d'un mât 5 placé sur une base 1 avec un support 11 pivotant à l'arrière du point de rotation, et d'un pied 4. Le mât 5 et le pied 4 peuvent chacun prendre une position articulée entre diverses sections susceptibles de rester rigidement fixes dans une position statique de pliage correspondant à celle du travail de la grue, mais avec possibilité de pliage en position de retenue totale sur la base 1 à support pivotant à laquelle l'ensemble est également uni par articulation. Application : réduction du poids transporté.
