OUR GROUP OF COMPANIES
What started as a small foundry established in 1865 by August Dango and Louis Dienenthal has since grown into a leading global group of companies. Today, this group is comprised of three strong brands with over 850 employees across nine countries.
Innovation, courage, determination, well-rounded diversification, and a deep sense of identification with the company help to shape our success – and, in turn, that of our customers.
Thanks to our extensive experience and expertise in metallurgy, mining, and environmental technology, our customers benefit from tailor-made solutions that enhance their profitability and strengthen their competitiveness in the global market.
THREE STRONG BRANDS

- HENCON – technology leader in cutting-edge special vehicles for the light metal industry, mining, vacuum technology, as well as the sales and servicing of forestry machinery
- TMT Tapping Measuring Technology– experts in the premium segment of tapping and measuring technology for blast furnaces and non-ferrous metal smelting furnaces; a joint venture between DANGO & DIENENTHAL in Siegen and PAUL WURTH in Luxembourg

OUR PROMISE
BETTER VALUES – this is the motto under the DANGO & DIENENTHAL logo. It is our brand promise, to which we feel committed as a group of companies.
This commitment extends not only to the high quality of our products but also to our social and sustainable behavior. It also forms the foundation of our corporate principles:
We are a family business that moves with the times and is constantly adapting to new requirements. This shall continue to be the case and be perceived accordingly by our stakeholders in all important international markets. We work in partnership with our customers and suppliers.
With our company headquarters in Germany, we are rooted in the Siegen region. We are therefore involved in local industry associations, maintain an active dialog with the regional public, and expect the same from our subsidiaries worldwide in their regions.
Our group of companies is managed by the management of
DANGO & DIENENTHAL Management GmbH; the shareholders only intervene in the operational business in consultation with the management.
We maintain a cooperative management style throughout our group of companies and always communicate transparently and efficiently at all levels. Constructive and critical suggestions for change and dialog are expressly encouraged.
We value our employees, involve them appropriately in decision-making processes, and want to work with each individual on a long-term basis. Every employee can also come to us with personal problems; we help as much as possible.
