Publication number: 20230242383Abstract: The invention relates to a mobile crane having a telescopic boom that is luffably coupled to a superstructure and that comprises a coupling section and at least one telescopic section supported therein in a retractable and extendable manner. At least one guying support is fastened to the coupling section and is connected to the coupling section or to the superstructure via a first guying and to a connection piece at a telescopic section via a second guying. In accordance with the invention, the second guying comprises at least two guying elements coupled with one another. The second guying is thereby adjustable in length and is thus adaptable to the extension length of the telescopic boom such that at least one of the mutually coupled guying elements is directly releasably connectable to the guying support.Type: ApplicationFiled: January 31, 2023Publication date: August 3, 2023Inventor: Yggve RICHTER
