Abstract: A mobile crane, such as a crawler crane, including an undercarriage having a chassis and a superstructure rotatably supported on the undercarriage and having a pivotable boom. At least two platforms are permanently arranged at the superstructure via which the superstructure is walkable. The platforms each comprise a base and a railing that are movable from a transport position in which they contact the superstructure into a work position in which the bases are walkable and are secured by the railings, and vice versa.

Abstract: The disclosure relates to a mobile crane, such as a crawler crane, comprising an undercarriage having a chassis, a superstructure rotatably supported on the undercarriage, and superstructure ballast, with the superstructure ballast comprising a ballast mounting apparatus vertically adjustable by means of a lifting device of the superstructure. In accordance with the disclosure, the ballast mounting apparatus is fastenable to the superstructure in an assembly position by means of a single connection element bearing the vertical load of the superstructure ballast. A centering means is furthermore provided that is adapted to take up transverse forces occurring in the assembly position.
