  • Patent number: 12187586
    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.

  • Patent number: 11795040
    Abstract: The disclosure relates to a ballast device for fastening to a crane having first and second ballast elements. The first ballast element has first connection means for a releasable fastening to the crane, while both ballast elements are releasably connected to one another via second connection means. According to the disclosure, the first ballast element comprises an assembly device having abutment elements to which an abutment means can be attached to raise the ballast device. The abutment elements are arranged or are positionable such that the abutment means can be selectively attached to the assembly device for raising only the first ballast element above its center of gravity or for commonly raising both ballast elements above their total center of gravity. The disclosure further relates to a mobile crane having at least one such ballast device.
