Abstract

Perfectionnement à installation de chargement, comportant un bras de grue et un bras de rallonge du premier bras et télescopiquement déplaçable à l'intérieur de celui-ci, et un conduit hydraulique qui s'étend du premier bras au second bras suivant une courbure suffisamment grande pour permettre de déplacer le bras télescopique vers l'extérieur par rapport au premier bras d'une valeur maximale. Le conduit hydraulique est sous forme d'une boucle avec une courbure en C qui est logée dans un espace défini par les parois du bras télescopique et/ou du premier bras de sorte que boucle, au moins dans la zone de transition à la courbure en C, soit délimitée par deux surfaces de paroi intérieures opposées du premier bras ou du bras télescopique, dans toutes les positions de déplacement de la courbure lorsque le bras télescopique est déplace par rapport au premier bras.
