Abstract
La présente invention concerne un verrouillage hydraulique de la flèche sur le bras de pivotement d'une drague ou d'une grue. Dans ce verrouillage, deux boulons de verrouillage 6, 7 peuvent être guidés transversalement dans le bras de pivotement et la flèche de la grue ou de la drague par l'intermédiaire de leviers 8, 9 articulés aux boulons 6 et 7 par une articulation intermédiaire 13, 14 et entraînés par au moins un cylindre hydraulique 10. Les deux leviers 8 et 9 sont reliés l'un à l'autre par l'intermédiaire d'un guidage parallèle 15. L'invention permet de rapporter sans modification des équipements différents sur un corps de machine de base.
