Abstract

Bei einem Gabelstapler-Fahrzeug mit einem hydraulischen Hub-Antrieb für die am Mast anhebbare und absenkbare Hebebühne und einem hydraulischen Neigungs-Stellantrieb für den Mast ist der Hubantrieb als einfach-wirkender Hydrozylinder (11) ausgebildet ist. Ein Hub-Steuerventil (14), das eine dem Anhebungsbetrieb zugeordnete Funktionsstellung (I) hat eine dem Stillstand der Antriebszylinderkolbens (13) zugeordnete federzentrierte Mittelstellung als Grundstellung (0) und eine dem Absenkungsbetrieb des Hub-Antriebszylinders zugeordnete Funktionsstellung (II) ist so ausgebildet, daß die Beträge der in den Funktionsstellungen I und II freigegebenen Strömungspfad-Querschnitte steuerbar einstellbar sind und zu den alternativen Auslenkungen eines VentilHaupt-Kolbens (14') proportional sind. Das Hub-Steuerventil (14) ist als 5/3-Wege-Ventil (14) ausgebildet, dessen Hauptkolben (14') mittels eines digital ansteuerbaren elektrischen Stellmotors (96) in seine den verschiedenen Funktionsstellungen (0, I und II) der Hub- Steuerventilanordnung (14) entsprechenden Positionen bewegbar ist. Zur Antriebskopplung des Stellmotors (96) und des Hauptkolbens (14') ist ein nicht-selbsthemmendes Getriebe vorgesehen. Ein Drucksensor (107) erzeugt für den Druck im Antriebsdruckraum (12) des Hub-Antriebszylinders (11) charakteristische elektrische Ausgangssignale, anhand derer die eine elektronischen Steuereinheit (103) eine selbsttätige Begrenzung des Aussteuerhubes des Hauptkolbens (14') auf einen Betrag vermittelt, dem ein lastgerecht-zulässiger Höchstwert der Bewegungsgeschwindigkeit der Hebebühne entspricht.
