The Liebherr LR 11000 is a 1,000 to 1,200-ton capacity lattice boom crawler crane built for heavy-duty industrial, infrastructure, and wind power projects. It fills the slot between the LR1750 (750 t) and the LR11350 (1,350 t) — and if you've ever watched one work a wind farm site in mountain terrain, you'd see immediately that the undercarriage is where most of the wear happens.
