Big Red One helps erect wind turbines
20 November 2014 by Daniel SearleA 750t Liebherr LTM 1750-9.1 crane has been used by German crane company Kran Saller to erect wind turbine towers.
Kran Saller, based in Deggendorf, added the crane to its fleet in July and recently used it to erect 89m-high concrete tower for 12 wind turbines.
The project, at the Berngerode wind farm at Schlitz, involved erecting the towers for 2.5MW wind turbines manufactured by GE. The crane was equipped with a Y-guying system and a 35m luffing jib.
Following that stage, Kran Saller used a Liebherr LR 1600/2 crawler crane to install segments of the steel tubular tower to the hub height of 139m, as well as the nacelle, hub and blades.
At almost 80t, the foundation rings were the heaviest components, with the steel tubular tower segments weighing in at 55t.
As the LTM 1750-9.1 is the largest crane in Kran Saller's fleet, the crane company added to the crane's livery the name 'Big Red One'. The next project planned for the crane by Kran Saller is erecting three wind turbines at the Hohenstein wind farm near Wiesbaden.
