Kran Saller has massively boosted its crane fleet by investing in an Liebherr LTM 1750-9.1 . The new flagship with a maximum load capacity of 750 tons was delivered in July 2014. The large crane was recently used at the Berngerode wind farm where it erected concrete towers up to 89 meters high for twelve wind turbines.
Big Red One
The crane livery with its name ‘Big Red One’ immediately clarifies its position as the largest crane in the Saller fleet. The red-painted cranes are the trademark of the Deggendorf-based company. Its maximum load capacity of 750 tons and maximum hoist height of 154 meters indicate the crane’s performance. It has variable equipment systems and massive flexibility during use.
Berngerode wind farm
The new LTM 1750-9.1 at Kran Saller managed to demonstrate its performance during its first jobs recently at Berngerode wind farm. At this wind farm at Schlitz near Fulda, it erected the first 89 meters of twelve concrete towers for 2.5 MW wind turbines manufactured by GE. For this job the crane was equipped with Y-guying system and a 35 meter luffing jib. The segments of the steel tubular tower up to the hub height of 139 meters, the nacelle, the hub and blades were then installed by a Liebherr LR 1600-2 crawler crane.

The heaviest parts were the foundation rings which each weighed in at almost 80 tons. Although the adapters used to connect to the steel tubular tower segments were considerably lighter at 55 tons, they had to be hoisted to a height of 89 meters by the LTM 1750-9.1.
And that is why the next project has already been planned for the LTM 1750-9.1 – it will go straight to the Hohenstein wind farm near Wiesbaden to erect three wind turbines.
