Zusammenfassung:The disclosure relates to a crane, in particular a lattice boom mobile crane, which comprises an upper carriage rotatable about a vertical axis of rotation and a floating ballast connected to the upper carriage via a floating ballast guide. The floating ballast guide comprises a drive for changing the distance of the floating ballast from the axis of rotation of the upper carriage. According to the disclosure, the floating ballast guide is connected to the upper carriage via at least one force transmission member. The force transmission member is configured to partially unload the floating ballast guide by an unloading force counteracting the weight force of the floating ballast, and to thereby introduce a corresponding counterforce into the upper carriage.
