Abstract

L'invention concerne un engin de levage mobile. L'engin est du type constitué d'un châssis porteur sensiblement horizontal muni de moyens de roulement, supportant une tour verticale et une flèche articulée sur ladite tour et il est caractérisé en ce que la tour est montée sur le châssis porteur par un axe d'articulation permettant le déplacement angulaire de la tour entre une position active verticale et une position d'effacement sensiblement horizontale et rabattue contre le châssis, la flèche étant alors ramenée en position sensiblement parallèle à la tour, ce repli permettant le déplacement de l'engin sous encombrement réduit et sans démontage. Application à une grue mobile portuaire.
