Abstract

Engin élévateur de personnel du type télescopique essentiellement caractérisé par le fait qu'il comporte un bras orientable articulé à sa base (2) sur une plateforme porteuse, ledit bras étant constitué de plusieurs éléments coaxiaux (3, 4, 5) extensibles télescopiquement les uns par rapport aux autres, actionnés entre eux par des vérins internes eux-­ mêmes télescopiques, du type à double effet, susceptibles d'être commandés en extension et en rétraction par la circulation (22, 23) appropriée d'un fluide sous pression, l'élément extrême (5) étant rendu solidaire de la tourelle. Telescopic type personnel lifting device essentially characterized by the fact that it has an arm orientable articulated at its base (2) on a carrying platform, said arm being made up of several coaxial elements (3, 4, 5) telescopically extendable with respect to others, actuated together by internal cylinders themselves same telescopic, of double effect type, susceptible to be ordered in extension and retraction by the appropriate circulation (22, 23) of a pressurized fluid, the extreme element (5) being made integral with the turret.

L'invention est applicable aux engins élévateurs por­ teurs de tourelle (6) pour les travaux sur réseaux électriques notamment. The invention is applicable to lifting machines for turret heads (6) for work on electrical networks especially.
