Description

Fahrzeugkran mobile crane
Die Erfindung betrifft einen Fahrzeugkran nach dem Oberbegriff des Anspruchs 1.The invention relates to a vehicle crane according to the preamble of claim 1.
Aus DE 202 03 506 U1 ist ein gattungsgemäßer Fahrzeugkran bekannt, der eine Bailastiereinrichtung aufweist, die eine Ballastaufnahme an der Drehbühne, eine Ballastablage an dem Unterwagen sowie eine Ballasthubvorrichtung umfaßt, die dazu vorgesehen ist, Ballast von der drehbühnenseitigen Ballastaufnahme zur unterwagenseitigen Ballastablage und umgekehrt zu heben. Ebenfalls bekannte Bailastiereinrichtungen sehen vor, den an der Drehbühne befestigten Ballast hinter der Drehbühne auf der Oberseite des Unterwagens abzulassen. Der jeweils aufgenommene Ballast wird vom Kranführer in die Kransteuerung eingegeben. Dabei können Fehler passieren. Um mit einem Fahrzeugkran ein Gewicht anheben zu können, muß der Kran mit einem entsprechend schweren Gegengewicht, dem Ballast, ausgestattet werden. Ist der Ballast zu klein, droht der Autokran umzufallen, wenn das Kippmoment des Krans zu groß wird. Das kann passieren, wenn das Objekt, das angehoben werden soll zu schwer ist, oder zu weit vom Kran entfernt abgesetzt werden soll.From DE 202 03 506 U1 a generic vehicle crane is known, which has a Bailastiereinrichtung comprising a ballast on the turntable, a ballast tray on the undercarriage and a Ballasthubvorrichtung, which is intended to ballast of the turntable side ballast receptacle for undercarriage ballast and vice versa to lift. Also known Bailastiereinrichtungen provide to release the attached to the revolving stage ballast behind the revolving stage on top of the undercarriage. The ballast picked up is entered into the crane control by the crane operator. This can happen mistakes. In order to be able to lift a weight with a mobile crane, the crane must be equipped with a correspondingly heavy counterweight, the ballast. If the ballast is too small, the truck crane threatens to fall over if the tipping moment of the crane becomes too great. This can happen if the object being raised is too heavy, or too far away from the crane.
Aufgabe der Erfindung ist es daher, einen verbesserten Fahrzeugkran der genannten Art zu schaffen, bei dem die Ballastierung möglichst fehlerfrei erfolgt.The object of the invention is therefore to provide an improved vehicle crane of the type mentioned, in which the ballast is carried out as error-free.
Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.This object is solved by the features of claim 1.
Hierdurch wird ein Fahrzeugkran geschaffen, bei dem die Ballasterfassung automatisiert ist. Die Erfassung des Ballastes erfolgt berührungslos mit Hilfe von Funkübertragung.As a result, a vehicle crane is created in which the Ballasterfassung is automated. The ballast is recorded without contact by means of radio transmission.
Vorteilhafterweise erfolgt die Funkübertragung unter Einsatz der RFID-Technik.Advantageously, the radio transmission takes place using the RFID technology.
Weitere Ausgestaltungen der Erfindung sind der nachfolgenden Beschreibung und den Unteransprüchen zu entnehmen.Further embodiments of the invention are described in the following description and the dependent claims.
