Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. 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 a ballast, wherein a position of the ballasting cylinder receiving the ballast is variable 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, the ballasting cylinder can be fixed in position via a locking mechanism, and the locking mechanism comprises a spring-loaded pin which can be drawn against a spring force, with the pivoting of the respective ballasting cylinder arranged at a pivot console being able to be carried out from the ground. 2. A mobile crane in accordance with claim 1 , wherein the at least one ballasting cylinder is pivotable about a pivot axis vertical with respect to the superstructure. 3. A mobile crane in accordance with claim 2 , wherein the at least one ballasting cylinder is received in the pivot console which is pivotable about a vertical pivot axis. 4. A mobile crane in accordance with claim 1 , wherein receiving apparatus for the ballast is provided on the undercarriage, with corresponding receiving means being arranged at the receiving apparatus such that the ballast can be placed down in the different positions on the receiving apparatus. 5. A mobile crane in accordance with claim 1 , wherein the at least one ballasting cylinder is mounted on the pivot console in turn mounted on a vertical pivot axis separate and spaced from the axis of rotation of the superstructure. 6. A mobile crane in accordance with claim 5 , wherein different counterweight radii are determined by a pivot angle and a length of the pivoting console. 7. A mobile crane in accordance with claim 1 , additionally comprising apparatus positioned on the undercarriage to receive the ballast.
