Abstract

Gegenstand der Erfindung ist ein Flurförderzeug mit einer vertikal beweglichen Lastaufnahmevorrichtung. Eine Vorrichtung zum vertikalen Bewegen der Lastaufnahmevorrichtung weist mindestens einen Hydraulikzylinder (5) und mindestens eine mittels eines Elektromotors (1, 1a) antreibbare Hydraulikpumpe (2, 2a) auf. Die angetriebene Hydraulikpumpe (2, 2a) weist eine Druckseite und eine Saugseite auf. Erfindungsgemäß ist die Saugseite der angetriebenen Hydraulikpumpe (2, 2a) mit dem Hydraulikzylinder (5) verbindbar. Zur Steuerung des Anhebens und/oder des Absenkens der Lastaufnahmevorrichtung ist mindestens ein stufenlos betätigbares elektrisches Schaltelement vorgesehen, das mit der elektrischen Impulssteuereinheit in Wirkverbindung steht. Besondere Vorteile ergeben sich, wenn das Flurförderzeug als Hochhubwagen, vorzugsweise als deichselgeführter Hochhubwagen ausgeführt ist.
