Abstract
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.
