LTM 1090-4.1 mobile crane: improved load capacity and outreach compared with the previous model LTM 1080/1. Considerable improvements in performance have also been achieved on the new four-axle all-terrain LTM 1090-4.1 mobile crane, which supersedes the LTM 1080/1. The load capacity of the telescopic boom has been increased by up to 22 %, and on the folding fly jib by as much as 33 %. The two-engine design with a performance-matched Liebherr crane engine ensures particularly economic crane operation.
