Special prefabricated elements specialist Klaus relies on fully individualised automation solutions
Special designs are the strength of Klaus Fertigteilwerk
Klaus Fertigteilwerk stands out above all in the production of special designs and everything that falls outside the norm, such as winding stairs. The precast plant belongs to Klaus Hoch- und Tiefbau GmbH and thus to the Klaus Group. The precast plant in Kissing has existed since the late 1960s and has developed into a best practice company under the name Klaus, currently employing around 115 people.
Located south of Augsburg, the precast concrete company supplies Bavaria and Baden-Württemberg with high-quality and individual precast concrete elements such as stairs, balconies, façade elements and special designs. The company works almost exclusively for the residential construction sector or private builder-owners, and only to a very little extent for the industrial construction sector.
Customised machines for special design expert
The newly installed Pluristar multifunctional plant from progress Maschinen & Automation combines the functions of an automatic stirrup bender, straightener, and a double bending machine. The Pluristar can process wire diameters from 8 - 16 mm and has a combined straightening system consisting of a roller straightener and a rotar straightening unit. This special combination enables flexible production of stirrups, straight bars and bars with large bends, and can thus cover the entire rebar processing from coil.

In reinforcement processing, the new M-System BlueMesh® mesh welding plant also stands out by its versatility. The specially adapted plant with a small footprint produces customised meshes according to individual specifications, causes no waste due to working directly from the coil and is easy to operate. This ensures a high quality of the product and Klaus’ special designs can be implemented easily and automatically. Some 50 reinforcement cages are produced per day on average. Depending on the order situation, a few more cages can be produced in the plant - 75 baskets in different sizes every day.
Thomas Heubeck, Technical Manager at Klaus Fertigteilwerk, comments regarding the investments made: “Thanks to the new machines, we have made a huge leap forward in reinforcement and can now produce precisely fitting cages for the stair formwork. The base basket then only needs to be attached to the corbel stirrups.” He adds, “For straight stairs, with or without a stair landing, the reinforcement is made to fit exactly, so the iron bender only has to make control measurements.”
The production of winding stairs is somewhat more complex. Here, the mat welding machine produces per metre for the top and bottom layers as well as for the edge baskets. These mats can be cut to size and added for the winding stairs.
In order to further increase the already existing high-quality production standards and the automation rate, Klaus additionally invested in customised stair mould systems from Tecnocom. With this mould systems the formwork work can be realised quickly, flexibly and automatically with very high precision.
“When purchasing the new mould systems, the decision was made in favour of Tecnocom because the products were individually adapted and manufactured to our needs. No other manufacturer could offer that in this way,” says Heubeck.

A mould system for staircases, model HT-Tec Plus - a special tilt stair formwork with 10 steps - a stair formwork Ramp-Tec Plus as well as a stationary table were delivered.

The automatically adjustable mould ramp for stairs with stair landing - model Ramp-Tec Plus offers an automatic variation of the slope of the ramp and the stair landing. With built-in slope sensors for the variation of the stair rise and by automatically adjusting the slope of the stair landing with electric control, it is possible to adjust the moulds to the respective requirement. In addition, the length of the stairs or the platform size can be set and the faultless surface quality can be produced. The mould surface of the stationary table is sanded to produce precast elements with a high surface quality. The use of side formers enables the production of elements in different sizes and thicknesses. The freshly poured concrete is compacted by high-frequency or pneumatic vibrators. The table is equipped with various heating systems to speed up the curing process.

Progress Group as a reliable partner
According to the company, German-speaking, reliable support was very important. The Progress Group meets these requirements. Without language barrier, small questions can be solved quickly and easily. Heubeck says, “Just today I spoke to the support team on the phone for a while. Good communication is essential for ambiguities that need to be resolved quickly.”

The positive experience of other companies with Progress also influenced the investment decision. Bending, welding, and shuttering can be done by any machine on the market, but the Progress Group was able to convince Klaus Fertigteilwerk with an attractive overall package.
