Abstract

Véhicule de manutention au sol comprenant un vérin de levage hydraulique pour un bâti de levage, un réservoir de fluide de pression, un groupe motopompe ainsi qu'une batterie d'accumulateurs pour a imenter le groupe, un distributeur pour commander le mouvement de levage et de descente et un accumulateur de fluide de pression, des mécanismes auxiliaires pouvant être alimentés à partir de l'accumulateur étant prévus. Un accumulateur asservi 61 pour les mécanismes auxiliaires est placé sur un circuit d'accumulateur asservi 60 séparé du groupe motopompe 14, lequel circuit est placé sur le retour 49 du distributeur 18 dans le circuit de motopompe.Ground handling vehicle comprising a hydraulic lifting cylinder for a lifting frame, a pressure fluid tank, a pump unit as well as an accumulator battery to control the group, a distributor to control the lifting movement and descent and a pressure fluid accumulator, auxiliary mechanisms being able to be supplied from the accumulator being provided. A slave accumulator 61 for the auxiliary mechanisms is placed on a slave accumulator circuit 60 separate from the pump unit 14, which circuit is placed on the return 49 of the distributor 18 in the motor pump circuit.
