A level-controllable crawler crane includes two crawler supports with rotating crawlers, which crawler supports are connected by a transversal bridge. A superstructure of the crawler crane includes a crane jib pivotable about a vertical axis and connected to the transversal bridge. A pivotable articulation connects the transversal bridge to the crane superstructure. At least one of the crawler supports is connected to the transversal bridge by a double link having a lower and an upper link. The lower link is articulated on the crawler support by a crawler support lower pivotable axis and on the transversal bridge by a transversal bridge lower pivotable axis. The upper link is articulated on the crawler support by a crawler support upper pivotable axis and on the transversal bridge by a transversal bridge upper pivotable axis. A drive pivots the links about the pivotable axis associated therewith.

The invention relates to a crawler crane comprising two crawler supports () with rotating crawlers (). Both crawler supports () are connected by a transversal bridge (). A superstructure () of the crawler crane comprises at least one crane jib that can pivot about a vertical axis and is connected to the transversal bridge (). A pivotable articulation connects the transversal bridge () in a pivotable manner to the crane superstructure (). At least one of the crawler supports () is connected to the transversal bridge () by means of a double link (). A lower link () of the double link () is articulated on the crawler support () by means of a crawler support lower pivotable axis () and on the transversal bridge () by means of a transversal bridge lower pivotable axis (). An upper link () of the double link () is articulated on the crawler support () by means of a crawler support upper pivotable axis () and on the transversal bridge () by means of a transversal bridge upper pivotable axis (). A drive (), in particular motorised drive, is used to pivot at least one of the two links () about the pivotable axis () associated therewith, the result being a level-controllable crawler crane, in which the expenditure for adjusting a base-work position is reduced.

The invention relates to a tracked running gear, in which two running gears are arranged parallel to one another and each running gear has a longitudinal member () and a running gear chain () which runs around the longitudinal member in the longitudinal direction thereof and forms an upper and a lower strand, and at least one traction drive, composed of a motor, transmission and a drive gearwheel which meshes into the running gear chain and also a deflecting wheel which permits chain tensioning by means of a movement relative to the fixed part of the longitudinal member, characterized in that at least one additional traction drive () which acts on the upper strand is provided on the longitudinal member, wherein the running gear length is changed or remains unchanged.
