Abstract

Die Erfindung betrifft einen Fahrzeugkran mit einem Unterwagen und einem drehbar auf diesem angeordneten Oberwagen (10) mit einer Einrichtung zur Aufnahme von Ballast. Erfindungsgemäß besteht die Einrichtung (18) zur Aufnahme von Ballast (28) aus mindestens drei vertikalen auf- und abbewegbaren Zugmitteln (24), die mit einer den Ballast (28) tragenden Palette oder Grundplatte (27) unterhalb der Gesamtschwerpunkte des Ballastes (28) verbindbar sind, um die Palette oder Grundplatte (27) an dem Oberwagen (10) heranzuziehen und mit ihm zu verbinden bzw. von diesem abzulassen.The invention relates to a vehicle crane with an undercarriage and a rotatably mounted on this superstructure (10) with a device for receiving ballast. According to the invention, the device (18) for receiving ballast (28) consists of at least three vertical up and down movable traction means (24) with a ballast (28) carrying pallet or base plate (27) below the overall center of gravity of the ballast (28). are connectable to pull the pallet or base plate (27) on the superstructure (10) and connect to him or to let go of this.
