Abstract
A mobile crane comprising a moveable undercarriage, an upper carriage mounted on the undercarriage so as to rotate about a vertical upper carriage axis of rotation and having a ballasting device, and a counterweight device that can be coupled to the ballasting device and comprises a counterweight base plate and at least one connecting element extending from the counterweight base plate for lifting and coupling the counterweight device to the ballasting device. The first arm in the ballasted state is connected to the counterweight base plate via a pivotable coupling element, which is pivotably mounted relative to the first arm and the counterweight base plate in such a way that the counterweight base plate can be adjusted in a linear movement radially to the upper carriage axis of rotation by simultaneously pivoting the first arm and the coupling element.
