Abstract
L'invention concerne un procédé de dressage d'une grue comportant un mât à l'extrémité supérieure duquel sont articulés une flèche et un chevalet à l'extrémité extérieure duquel sont fixés le câble de retenue de flèche et le câble de réglage de flèche, ce dernier partant du chariot. Le procédé est remarquable en ce que le câble de retenue de flèche et le câble de réglage de flèche ont une longueur prédéterminée, invariable pendant le dressage et pendant le fonctionnement de la grue et telle que, lorsque la grue est en position repliée, ils sont tendus ou n'ont qu'un léger mou et qu'en même temps que l'on dresse le mât de l'horizontale à la verticale, on lève la flèche. Le procédé permet de réaliser un dressage simple et rapide de la grue sur le chantier.
