CRAWLER CRANE AND METHOD FOR ADJUSTING A BASE-WORK POSITION OF SAID TYPE OF CRAWLER CRANE |
摘要 |
<p>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.</p> |
