Abstract

L'ensemble formant une poutre télescopique comprend un premier et un second élément de poutre télescopique. Dans le premier élément 1, est prévue une première cremaillère 4 et, dans le second élément 11, une seconde crémaillère 12. Un premier pignon 9 engrène les crémaillères 4, 12. Le déplacement d'une tige de piston 8 liée au pignon 9 fait déplacer l'élément 11 par rapport à l'élément 1. Un troisième élément 21 peut avec un arrangement semblable comprenant une crémaillère 15 et une quatrième 23 montées respectivement sur 11 et 12 faire déplacer 21 par rapport à 11. On obtient alors une poutre à trois éléments télescopiques. Utilisable dans les grues, des bras télescopiques de plates-formes et des appareils du même genre.
