Abstract

La présente invention concerne le dépliage d'une flèche distributrice brisée d'une grue. Un câble 16 de longueur constante passe sur une poulie 18 du pied de flèche. Ses extrémités sont fixées sur la pointe de flèche et à l'arrière du palonnier 17 solidaire du mât intérieur coulissant de la grue. Les couples crées par ce câble par rapport aux articulations pied de flèche sur la pointe et pied de flèche sur mât permettent de soulever la flèche en gardant le pied contre le mât et la pointe horizontale, sans l'amener en appui au sol, la pointe étant soutenue par le câble 16. Application : dépliage de flèche sur un chantier encombré.
