摘要

The crane (10) has a chassis, and a rotating assembly arranged on the chassis. A rotating platform (18) is rotatable over the rotating assembly, where a main extension arm (20) and a derrick extension arm (22) are arranged on the rotating platform. The rotating platform is mounted on the rotating assembly via a distance pipe (16). A guiding frame is hinged at the distance pipe, with which a ballast wagon is connected via a distance frame. The distance frame is connected with the ballast wagon via an individual rotational axis.
