eine Messeinrichtung vorgesehen ist, durch die eine für den vertikalen Abstand der Unterflasche (5) vom Kopf (3) des Auslegers (2) repräsentative Messgröße zumindest in einem Annäherungsbereich zum Kopf (3) des Auslegers (2) hin erfassbar und an die Steuerung (6) gebbar ist,
dass in die Steuerung (6) Parameterwerte zur Kennzeichnung der jeweiligen Krankonfiguration eingebbar sind und
dass der Grenzwert, der die zulässige Annäherung der Unterflasche (5) an den Kopf (3) des Auslegers (2) begrenzt, durch die Steuerung (6) in Abhängigkeit von der Krankonfiguration ermittelbar ist.1. Crane ( 1 ) with an adjustable boom ( 2 ), with a single or multi-leg over the head ( 3 ) of the boom ( 2 ) guided hoisting rope ( 4 ), the unwound length of which can be adjusted using a hoist ( 7 ) is, with a bottom block ( 5 ) attached to the lifting cable ( 4 ) for receiving a load to be lifted and with a safety device connected to the control ( 6 ) of the crane ( 1 ) for signaling purposes, which, when a limit value for the maximum permissible approximation of the Bottom block ( 5 ) on the head ( 3 ) of the boom ( 2 ) switches off a lifting movement of the lifting mechanism ( 7 ), characterized in that
A measuring device is provided, by means of which a measurement variable representative of the vertical distance of the bottom block ( 5 ) from the head ( 3 ) of the arm ( 2 ) can be detected at least in an area of proximity to the head ( 3 ) of the arm ( 2 ) and sent to the control ( 6 ) can be given,
that parameter values for identifying the respective crane configuration can be entered in the control ( 6 ) and
that the limit value, which limits the permissible approach of the bottom block ( 5 ) to the head ( 3 ) of the boom ( 2 ), can be determined by the control ( 6 ) depending on the crane configuration.
