Abstract: The disclosure relates to a mobile crane comprising a mobile undercarriage, an upper carriage rotatably mounted on the undercarriage, and a counterweight device which can be coupled to the upper carriage and which comprises a counterweight base plate and at least one connection element extending substantially perpendicularly to the counterweight base plate and connected thereto for lifting and coupling the counterweight device to the upper carriage. The counterweight device may comprise a carrier plate connectable to the connection element above the counterweight base plate, wherein at least one pivot beam is mounted on the carrier plate so as to be pivotable about a vertical axis, on which first counterweight elements are stackable. The disclosure further relates to a counterweight device for a mobile crane according to the disclosure and to a method for mounting the counterweight device on the upper carriage of a mobile crane according to the disclosure.

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.

Abstract: The disclosure relates to a mobile crane that comprises a travelable undercarriage, a superstructure rotatably supported on the undercarriage, and a counterweight device couplable to the superstructure. The counterweight device comprises a counterweight base plate and at least one connection means for raising the counterweight device and for coupling it to the superstructure. The disclosure furthermore relates to a counterweight device for a mobile crane in accordance with the disclosure.

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.

Abstract: The invention relates to a mobile crane having an undercarriage and a superstructure rotatable with respect to the undercarriage about an axis of rotation and having a ballast receiving apparatus arranged at the superstructure and having at least one ballasting cylinder for receiving ballast. In accordance with the invention, the position of the ballasting cylinders receiving the ballast is varied in the ballast receiving apparatus such that the ballast can be received in positions of different distances from the axis of rotation of the superstructure.

Abstract: This invention relates to a crane comprising an undercarriage and a turntable rotatable with respect to the undercarriage with a counterweight and a mounting point for the attachment of a winch, wherein the counterweight includes at least one winch pick-up means for the temporary attachment of a winch to be mounted on the turntable, wherein the winch can be attached to the winch pick-up means such that the winch can be pivoted about a vertical axis.

Abstract: The present disclosure relates to a mobile crane having an undercarriage and a superstructure rotatable about an axis of rotation with respect to the undercarriage and having a ballast mounting apparatus couplable to the superstructure. The present disclosure is furthermore directed to a corresponding ballast mounting apparatus.

Abstract: This invention relates to a mobile crane with a traveling undercarriage and an uppercarriage rotatably mounted on the same, to which on the one hand a boom is luffably articulated and on which on the other hand a counterweight assembly is arranged on the uppercarriage, in which a counterweight plate is connectable via a counterweight receptacle, in that the same is pivotable from a pick-up position into a deposited position about at least one bolt arranged on the counterweight receptacle. According to the invention, at least one further bolt is arranged on the counterweight receptacle parallel to the at least one bolt, which while swinging down the counterweight plate engages into a corresponding curve-shaped recess of the counterweight plate for securing the same.
