Abstract

La présente invention concerne une grue équipée d'un dispositif de montée et de sortie télescopique de sa tour. Cette grue se caractérise en ce que sa partie inférieure externe 4 est reliée par l'intermédiaire d'un axe de rotation 3 à une construction de support 10 d'un chariot supérieur, tandis que la partie supérieure 5 de la tour peut être fixée au moyen d'une tige de poussée il articulée en 12 à la construction de support précitée ainsi qu'à l'extrémité inférieure de la partie superieure interne 5 de ladite tour de la grue. Le levage est assuré au moyen de presses hydrauliques 6. L'invention permet d'ériger des tours de grue en une seule opération.
