Abstract

Cette invention concerne une flèche repliable pour grues télescopiques. Cette flèche comporte un ensemble de poinçon et un ensemble de flèche. L'ensemble de poinçon comprend un poinçon principal relié à un tirant arrière, et par un tirant classique au pied de flèche, et un poinçon secondaire qui peut être rendu angulairement solidaire du poinçon principal dans la condition de travail de la flèche, mais qui est libére lors du repliage de celle-ci, en prenant alors appui sur le mât à la maniere d'une potence, pour contrôler le mouvement de la partie avant de la flèche, laquelle est reliée au pied de flèche par un tronçon de pliage sur lequel les tirants soutenant cette partie avant de la flèche sont attelés. Un ensemble de ce type permet le repliage et le dépliage de la flèche en position télescopée du mât, donc sans encombrement au sol.
