The Heinzel Group is building a second large paper machine for the production of bleached kraft paper at the Zellstoff Pöls AG site in Austria. So-called MG papers are used for flexible packaging and show superior market growth. With the new machine, a total of 200,000 tons of MG papers can be produced annually at the Pöls site.
With a diameter of 7.3 meters and a total weight of around 200 tons, the drying cylinder is the largest welded high-precision drying cylinder in the world.
Location: Styria, Austria
Commissioned by: Zellstoff Pöls AG
Performance period: 2018 – 2019
The rolls of a paper machine require a high-precision alignment, especially for parallelism. In order to meet these requirements, a high-precision network for SMR adapters over an area of 130 m x 25 m and a total height of approx. 20 m was created before the beginning of the assembly work. This network serves as the basis for all stakeout, setup and control surveying activities throughout the entire construction period. This procedure made it possible to precisely align the steel structure in advance, which made the alignment and assembly of the rollers much easier and saved a significant amount of time.
Another challenge was the installation of the Yankee cylinder. The lower half was levelled exactly in front of the hall to facilitate assembly of the upper half. After assembling the two halves, the entire Yankee cylinder was exactly aligned by using the prepared axle markings and removed.
The settlement area of the Upper Styrian town of Pürgg is directly threatened by a rockfall. An extensive monitoring programme was executed to monitor the rock face both during the construction of a protective dam and afterwards.

The VERBUND power plant Ybbs-Persenbeug was Austria’s first power plant on the Danube and is located in Lower Austria. The interior of the power plant has been undergoing modernization since 2014. One machine set (turbine and generator) is renewed each year, and all six vertical machine sets are to be replaced by 2022. This will significantly increase the power generation of the power plant. The resulting additional generation corresponds to the annual electricity consumption of 22,000 households.
The 460 m long dam wall holds back the Danube over a length of about 34 km and up to a height of 10.9 m. The dam will be built on the banks of the Danube. The volume of the reservoir is approx. 74 million m³, the targeted water level is 226.2 m above sea level.
The two locks are located at the left, northern end of the dam, each with a usable length of 230 m and a usable width of 24 m.
The weir consists of 5 weir fields with a width of 30 m each and is located in the middle of the dam wall.
Location: Lower Austria; Austria
Client: VERBUND Hydro Power GmbH/Andritz AG
Performance period: 2013 -2018
The power plant has 7 machine units, six of which are vertically installed Kaplan turbines and one Kaplan bulb turbine. The measurement was carried out on machine sets 4, 5 and 6. The aim of the survey was a target-performance comparison of the guide vane positions in the guide vane as well as a geometry determination. The contour of the impeller casing was also determined by a target/actual comparison.
In addition, the measurement was carried out at the lower head of the sluice system before dismantling the mortise gate drives as a basis for realignment in the course of assembly with the new back suspension beams.
The full extension of the 8.3 km long Gleinalm tunnel comprises the construction of the second tube and the general renewal of the existing tube. The new tunnel tube was excavated by blasting and opened to traffic in June 2017. Afterwards the general refurbishment of the existing tunnel tube, which is almost 40 years old, will take place.
