Abstract

L'invention concerne un entraînement hydraulique (A) servant à entraîner au moins un actionneur hydraulique, présentant au moins une pompe hydraulique pouvant être entraînée par un moteur électrique (M) et au moins une conduite hydraulique (L) acheminant un fluide hydraulique et permettant de raccorder la pompe hydraulique (2) à l'actionneur hydraulique. L'objectif de l'invention est de créer un entraînement hydraulique (A) efficace sur le plan énergétique et peu onéreux. À cet effet, l'entraînement hydraulique selon l'invention présente au moins un dispositif (7) servant à détecter la pression réelle régnant dans la conduite hydraulique (L) ainsi qu'une unité de commande électronique (10) connectée audit dispositif ainsi qu'au moteur électrique (M) et conçue de sorte qu'elle coupe automatiquement le moteur électrique (M) lorsque la pression réelle détectée est supérieure ou égale à une pression de consigne spécifiée et met en marche automatiquement le moteur électrique lorsque la pression réelle est inférieure à la pression de consigne.
