Abstract
L'invention concerne une flèche télescopique selon le brevet principal. Cette flèche comporte par exemple deux volées télescopiques 6, 7, à commande hydraulique, et une volée télescopique 8, à commande mécanique au moyen d'une barre de retenue 13, amovible, dont une extrémité peut être assujettie à la base 5 de la flèche, et dont l'extrémité libre porte une pièce de pression 13c et un dispositif de traction 13d, diamétralement opposés l'une à l'autre ; selon le montage de la barre 13, c'est un bossage de la pièce 13c ou un cliquet porté par le dispositif 13d qui, lors du déploiement ou de la rétraction de la volée télescopique, coopèrent avec plusieurs boutonnières 15 à 15c, réparties sur la longueur de la volée à commande mécanique 8. L'invention est applicable en particulier aux grues automotrices.
