Claims (6)

  1. Installation hydraulique pour des engins de travail équipés d'outils de travail, notamment pour un chargeur à roues (1), un chariot élévateur à fourche ou analogue, comportant un système de suspension de charge (9), constitué par au moins un accumulateur hydraulique (16-19) et qui est raccordé aux canalisations hydrauliques (10,11), qui sont affectées au soulèvement et à l'abaissement de l'outil de travail, entre le ou les vérins de levage (12,13) et une soupape de commande (14), le système de suspension de charge (9) pouvant être activé ou désactivé en fonction d'états de fonctionnement prédéterminés, caractérisée en ce que pour réaliser un réglage variable de la pression de charge de l'accumulateur hydraulique (16-19) sur la pression de charge respective du ou des vérins de levage (12,13), il est prévu au moins une buse (21) reliée à plusieurs soupapes formant distributeurs (15,22,33) entre le système de suspension de charge (9) et le ou les vérins de levage (12,13), les soupapes (15,22,33) étant actionnées par l'intermédiaire d'interrupteurs de pression (29-32) prévus dans les canalisations de commande pilote (24-27) entre un générateur de commande pilote (28) et les soupapes de commande (14).
  2. Installation hydraulique selon la revendication 1, caractérisée en ce que les soupapes formant distributeurs (15,22,33) sont agencées sous la forme de soupapes à 2-2 voies.
  3. Installation hydraulique selon les revendications 1 ou 2, caractérisée par un by-pass (20) installé entre le système de suspension de charge (9) et le vérin hydraulique (12,13) sur le côté soulèvement (10) qui est pourvu de la buse (21).
  4. Installation hydraulique selon l'une des revendications 1 à 3, caractérisée par une soupape formant distributeur (33), qui bloque la buse (21), notamment une soupape magnétique.
  5. Installation hydraulique selon l'une des revendications 1 à 4, caractérisée par au moins un interrupteur prévu à une hauteur prédéterminée sur le châssis, notamment le châssis avant de l'engin de travail (1), notamment un interrupteur inductif pour débrancher le système de suspension de charge (9).
  6. Installation hydraulique selon l'une des revendications 1 à 5, caractérisée par un interrupteur principal, qui active le système de suspension de charge (9) et est disposé notamment dans la cabine (4) du conducteur de l'engin de travail (1).
