Abstract

Hubmast, insbesondere für einen Hochregalstapler, mit einem Standmast (10) und mindestens einem ausfahrbaren Mastschuss (20) und mit zwei parallel seitlich am Mast angeordneten Hubantrieben (14,16) zum Ausfahren des Mastschusses (20) aus dem Standmast (10), und einer Steuerung für die Hubantriebe, wobei eine Regelvorrichtung für die beiden Hubantriebe (14,16) vorgesehen ist, mit der eine Wegdifferenz der Hubwege der Hubantriebe gemessen wird und die Hubantriebe so gesteuert werden, dass die Wegdifferenz null bleibt.
