Abstract

La présente invention concerne une plateforme élévatrice hydraulique à six cylindres comprenant une plateforme élévatrice gauche (1) et une plateforme élévatrice droite (2), chacune comprenant un boîtier de commutation, une base (3) et une table de travail (4). Un bras élévateur (5) est disposé entre la base (3) et la table de travail (4). Les plateformes élévatrices gauche et droite (1, 2) sont chacune équipées de deux cylindres principaux coplanaires (6, 7) et de cylindres auxiliaires (8, 9). La chambre supérieure du cylindre principal (6) de la plateforme élévatrice gauche (1) est reliée en série à la chambre inférieure du cylindre auxiliaire (9) de la plateforme élévatrice droite (2). La chambre inférieure du cylindre auxiliaire (8) de la plateforme élévatrice gauche est reliée en série à la chambre supérieure du cylindre principal (7) de la plateforme élévatrice droite (2). Les plateformes élévatrices gauche et droite (1, 2) sont également pourvues respectivement d'un cylindre principal unique (10). Grâce à une conception utilisant six cylindres hydrauliques, le problème d'élévation asynchrone des deux côtés de la plateforme élévatrice est surmonté, de sorte que l'équilibre soit plus stable quand la plateforme est élevée, la pression de départ instantanée de la plateforme est réduite de 30 MPa à 20 MPa, atténuant de ce fait le problème de l'excès de pression dans le cylindre et réduisant les conditions requises en termes de capacité pour les éléments hydrauliques du système.
