Title (EN) IMPROVEMENTS IN OR RELATING TO DRIVE SYSTEMS OR HYDRAULIC ELEVATORS
(FR) PERFECTIONNEMENTS RELATIFS A DES SYSTEMES D'ENTRAINEMENT
Abstract: front page image
(EN)A hydraulically driven elevator or lift is provided with counterbalance means to at least partly counterbalance the load imposed by the load carrier or lift car. Operation of the counterbalance means, which includes a substantially constant volume of pressurised fluid, does not involve any interference with the working fluid of the hydraulic drive system.
(FR)La présente invention se rapporte à un pont élévateur hydraulique doté d'un moyen de contrepoids permettant d'équilibrer au moins partiellement la charge imposée par le porte-charge ou la cabine de monte-charge. Le fonctionnement du moyen de contrepoids, qui contient un volume sensiblement constant de fluide sous pression, n'implique aucune interférence avec le fluide de travail du système d'entraînement hydraulique.
