Automation of prestressed hollow-core slab production at the Habau Group
The modernisation of production facilities is of central importance in the construction industry in order to remain competitive and meet the increasing demands of the market. The Habau Group, Austria's fourth largest construction company, has recognised this and carried out a comprehensive renovation of the production plant for prestressed hollow-core slabs at the precast plant in Perg. With many years of experience in the production of precast concrete elements, it was time to replace the old plant, which had been in use for over four decades, with a modern, automated solution. This investment brings significant improvements in terms of efficiency, quality and cost savings.
The option of producing different ceiling thicknesses on 3 lines with a width of 2.40 metres offers customers additional flexibility. The S-Liner® slipformer, the centrepiece of production, is characterised by its modular design. Different heights within a product range can be realised effortlessly. To switch to another product, simply replace the production-specific module. Thanks to its special design and the use of earthmoist concrete, the S-Liner is particularly economical and impresses with its simple operation and ease of maintenance. A central element of the new plant is the automated multistressing technology, which enables the prestressing of the
strands in a single work step. This ensures a more even distribution of tension and increases the structural integrity of the slabs. The use of a multifunctional trolley, which places the strands and oils and cleans the production lines, also helps to optimise the production process. The automated concrete aspirator and the right-angle cutting machine complete the production process.
Development opportunities with the Progress Group
Cooperation with the Progress Group, which had already supplied a mesh welding plant to the Habau Group several years ago, played a decisive role in the modernisation. The Progress Group and its subsidiary Echo Precast Engineering were once again chosen for the new production line.
A lot has happened on the market and in order to be able to continue working in a progressive way, we have completely modernised the plant.
