Abstract

L'invention concerne un engin de manutention à bras télescopique qui comprend un système d’actionneur hydraulique (6) porté par un deuxième tronçon (22) du bras monté coulissant dans un premier tronçon, et un circuit de commande hydraulique qui comprend un système de conduite qui s’étend au moins en partie à l’intérieur du bras et qui est raccordé au système d’actionneur hydraulique (6) pour l’alimentation dudit système d’actionneur hydraulique (6). Le système de conduite comprend au moins une conduite (4, 4’) hydraulique flexible qui s’étend à l’intérieur du bras et qui présente une première portion (41) montée fixe par rapport au premier tronçon (21) ; une deuxième portion (42) montée fixe par rapport au deuxième tronçon (22) ; et une troisième portion (43) en forme de U qui relie entre elles la première portion (41) et la deuxième portion (42). La concavité de la troisième portion (43) en forme de U est orientée vers l’extrémité du premier tronçon (21) qui est opposée à l’extrémité du premier tronçon (21) qui définit l’ouverture à l’intérieur de laquelle s’étend le deuxième tronçon (22).
