Im Kommissionierbetrieb, bei dem die Bedienperson Lasten, beispielsweise Lastbehälter, aus dem Regal entnimmt oder in das Regal ablegt und Waren oder Lastbehälter auf dem Lastaufnahmemittel ablegt oder anhebt, erfolgt in der Regel in Betrieb in stehender Position. Wird das Hochrealflurförderzug zum Ein- und Auslagern von Paletten oder anderen Ladungsträgern verwendet oder sind längere Strecken in der Regalanlage zurückzulegen, erfolgt der Betrieb in sitzender Position, in dem die Bedienperson auf dem Fahrersitz im Fahrerstand Platz nimmt.Such high rack trucks are operated by the operator located in the driver's station both in a standing position and in a sitting position. In order-picking operation, in which the operator removes loads, for example load containers, from the rack or stores them in the rack and deposits or lifts goods or load containers on the load-carrying means, the machine usually operates in a standing position. If the high real-estate conveyor is used for storing and retrieving pallets or other load carriers, or if longer distances are to be covered in the racking system, the operation takes place in a sitting position, in which the operator sits down on the driver's seat in the driver's seat.
