The challenge

Wind energy plant with modular steel tower

The first wind energy plant with a modular steel tower in the world was erected in Austria. The individual tower segments are made of chamfered steel elements that are screwed together on the building site. The next assembly step is to then place them on top of each other and also screw them together. The Prangl experts are always the right people for this type of special assignment.

Our solution

650 tonne crawler crane with an extra high main boom

The wind energy plant was installed near to Scharndorf in Lower Austria on a modular steel tower with a hub height of 135 metres. For the main assembly process, it was necessary to use a “mobile” large crane. A 650 tonne crawler crane proved to be the right piece of equipment in the end. Due to the new system type and the required lashing gear, the main boom had to be set up higher than normal. In total, the entire crane system was 156 metres high and had a total weight of 950 tonnes.

Successful completion due to experience with wind energy

In addition to the large crane, all sorts of additional equipment was used: 1x 250 tonne telescopic crane, 1 x 6 tonne telehandler with long forks, 2 x 12 metre scissor lifts, 1 x 22 metre telescopic boom lift with crawler track and 1 x 28 metre telescopic boom lift. 30 excavator mats made of special wood were also provided. Prangl was entrusted with this showcase due to our decades of experience in wind energy, as well as our diverse fleet. The project was completed fully satisfactorily by the yellow team despite the new conditions.

Building a prototype steel tower with support from Prangl: That’s how great ideas take shape!
