Abstract
L'invention concerne une flèche télescopique de levage de charges. Elle comporte une première section fixe et au moins deux sections mobiles, un vérin hydraulique dont le cylindre est accouplé avec la seconde section et dont la tige de piston est accouplée avec la première section, et des chaînes destinées à étendre et à rétracter la troisième section. Des dispositions sont prises pour permettre un mouvement limité de la tige de piston dans la première section afin d'en éviter toute déformation nuisible. L'invention s'applique notamment à des grues mobiles.
