Abstract

Vorrichtung zur Notabsenkung eines Lasttragmittels bei einem Stapler, insbesondere Schubmaststapler, mit einer in einem Ventilblock (22) untergebrachten Ventilanordnung, über welche der Zufluss und Abfluss eines hydraulischen Mittels zu und von einem Hubzylinder (10) für das Lasttragmittel gesteuert wird, einem Bypass (42) zwischen dem Hubzylinder und einem Tank (28), einem Sperrelement (50) im Bypass und einer ein Seil (52) enthaltenden von einem Bediener betätigbaren Betätigungsvorrichtung (58), durch welche das Sperrelement in die Öffnungsstellung bringbar ist, wobei der Bypass von einem Bypasszweig im Ventilblock gebildet ist, ein schraubenförmiges Sperrelement mit einem Außengewindeabschnitt in einer Gewindebohrung des Ventilblocks eingeschraubt ist und in der vollständig eingeschraubten Stellung den Bypasszweig absperrt, ein ein Drehmoment übertragendes Seil mit einem Ende drehfest mit dem Sperrelement verbunden ist und am anderen des Seils eine Handhabe zur Drehung des Seils angebracht ist.
