Abstract
The invention relates to a mobile crane, that comprises a mobile undercarriage and a superstructure rotatably supported on the undercarriage and having a boom and a ballasting device. The ballasting device picks up or places down one or more counterweight elements by means of a hoisting device. In accordance with the invention, a placement device is provided that is connected to the undercarriage and comprises at least one movable placement part that is movable from a travel position into a placement position and vice versa. In this respect, the travel position is characterized in that the length of the undercarriage is reduced, and the crane is travelable on the construction site, whereas the placement position is characterized in that counterweight elements can be placed on the placement part by means of the ballasting device and the length of the undercarriage is increased in comparison with the travel position.
