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.
Claims11
A mobile crane having an undercarriage and a superstructure rotatably mounted upon the undercarriage about an axis of rotation and having a ballast receiving apparatus arranged at the superstructure and having at least one ballasting cylinder arranged for receiving ballast from the undercarriage and moving the ballast onto the superstructure, wherein
- position of the ballasting cylinder arranged for receiving the ballast from the undercarriage is variable in the ballast receiving apparatus such that the ballast is receivable from the undercarriage in positions of different distances from the axis of rotation of the superstructure.
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, wherein
- 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.
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, wherein
- 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, and
- the at least one ballasting cylinder (20) is mounted on a pivoting console (22) in turn mounted on a vertical pivot axis (24) separate and spaced from the axis of rotation (16) of the superstructure (18).
