The first wind energy plant with a modular steel tower in the world was set up 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 wind energy plant was installed near to Scharndorf, Lower Austria on a modular steel tower with a hub height of 135 metres. The Prangl experts are trained for this type of special assignment.
The main assembly required the use of 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.
In addition to the large crane, all sorts of additional equipment was used: 1x 250 tonne telescopic crane, 1 x 6 t 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 because of their decades of experience in wind energy, as well as their diverse fleet. The project was completed satisfactorily by the yellow team despite the new conditions.
