Abstract

Die vorliegende Erfindung betrifft ein Verfahren zum Betrieb eines Flurförderzeugs (10) mit wenigstens einem bremsbaren Antriebsrad (22), wobei eine zulässige Maximalgeschwindigkeit des Flurförderzeugs (10) in Abhängigkeit von einer aufgenommenen Last (24, 24') bestimmt wird. Erfindungsgemäß wird vorgeschlagen, dass die maximale Geschwindigkeit abhängig von einem Abstand (A) ermittelt wird, der zwischen einem ersten (34) und einem zweiten (36) Bauteil des Flurförderzeugs (10) gemessen wird und sich abhängig von der auf das bremsbare Antriebsrad (22) wirkenden Radaufstandskraft ändert, wobei sich die beiden Bauteile (34, 36) in Abhängigkeit der aufgenommenen Last (24, 24') relativ zueinander bewegen. Ferner betrifft die Erfindung ein Flurförderzeug mit einer zentralen Steuereinheit zur Durchführung des erfindungsgemäßen Verfahrens.

The present invention relates to a method for operating an industrial truck (10) with at least one brakable drive wheel (22), wherein a permissible maximum speed of the industrial truck (10) in dependence on a recorded load (24, 24 ') is determined. According to the invention, it is proposed that the maximum speed is determined as a function of a distance (A) measured between a first (34) and a second (36) component of the industrial truck (10) and dependent on the braking drive wheel (22 ) acting Radaufstandskraft changes, wherein the two components (34, 36) in dependence of the received load (24, 24 ') move relative to each other. Furthermore, the invention relates to an industrial truck with a central control unit for carrying out the method according to the invention.
