The history of krauth technology

Development of the company

The story of krauth technology GmbH started with “Professor Alfred Krauth Apparatebau GmbH & CO.KG” and has been closely related to the history of public transport since 90 years. Continuously increasing mobility shaped the development in public transport and even nowadays, it is a driving force for further innovation. The company’s head office is in “Eberbach am Neckar”. The Staufer town which was founded in the 13th century is located approximately 30 kilometres to the east of Heidelberg amidst the forested low mountain range of the Odenwald.

In these days, the company is an inherent part of the Shanghai DuTechHoldings Ltd.

Milestones on the way to success

A brilliant invention, the so-called “Galoppwechsler” (coin dispensers), prompted Professor Alfred Krauth to found his company in Dusseldorf in 1926 and registered for the production and sales of coin dispensers. The production plant was located in Mittweida/Saxony. Therewith, the basis for the successful company development had been laid. Soon, the products of Krauth were widely used in the public transport industry. After the Second World War, the production of the so-called “Galoppwechsler” (coin dispensers) in Mittweida/Saxony had fully collapsed and the production facilities and plants had also been lost. Even though, at this time, Professor Alfred Krauth was of an advanced age already, he started to rebuild the company in 1948 in his summer residence in Eberbach. In 1950, Professor Krauth received assistance from the engineer Otto Langkait, who assumed the technical management of the company. The inventions, technical drawings and constructions of Otto Langkait provided the decisive impulses for the further development of the product lines. The products of Krauth gained increasing recognition when the company started to participate in exhibitions and trade fairs. The products were used in almost every public transport vehicle. In 1951 Krauth presented their range of products for the first time to the public on the fair “Schiene und Straße” (rail and road) in Essen.

As the coin dispenser as well as the money changers type FIX and LUX sold very well, larger production facilities became necessary to cope with the increasing order volume. Adequate premises were sought and found at Ohrsbergweg 1 in Eberbach. The first Krauth factory building was constructed in 1954 and put into service in 1955 in Eberbach.

Many things changed over the centuries...
... one thing persists: the quality of krauth products...

The further product development has always taken account of the permanently changing process within traffic companies. When personnel accompanying the vehicle and selling tickets with the help of a coin changer and a moneybox were no longer in service, the installation of stationary pay desks became necessary. Later then, tickets were no longer sold by special staff but the driver of a vehicle issued and sold tickets (one-man operation).

In 1988 a second factory building was constructed, connected with the old building by a passage. Sophisticated products with regard to quality, function and cost effectiveness imply the use of high-quality materials and components, state-of-the-art production lines and the commitment of skilled staff. To meet the requirements on modern production, a new production hall stretching over more than 3000 m2 was set up in 1997.

In 1997, the existing quality assurance system was reorganized and completed in compliance with the internationally applicable guidelines defined in EN ISO 9001

The Krauth Consortium

In 1999, the companies Professor Alfreth Krauth Apparatebau GmbH & Co. KG, Printon Elektronische Drucksysteme GmbH (subsidiary since 1998) and ART Automatisierung and Rechnertechnik GmbH (subsidiary since 1999) merged to form the Krauth Consortium. The merger aimed at achieving synergy effects by combining the technical expertise of the companies to optimise development potentials.

Krauth Apparatebau becomes krauth technology

The Krauth Consortium did not manage to realise the desired synergies and in 2008 the necessary liquidity could no longer be ensured. A company take-over was the consequence and the Nußbaum Group assumed the complex task of restructuring. Under the chairmanship of Philipp Nußbaum the company continued under the name “krauth technology”.


Since January 2016: krauth technology under new ownership

Investments and consolidation measures within the Nußbaum Group and especially in their core business workshop equipment resulted in the necessity to search for new investors for krauth technology. Consequently, Nußbaum Technologie Holding GmbH & Co. KG sold krauth technology GmbH to DuTech Holdings Ltd.
As krauth technology is aiming at expanding their activities to an international scale what will consequently induce additional capital requirements, Nußbaum Technologie decided in 2016 to look for a new owner for krauth technology
