DANGO & DIENENTHAL Unternehmensgruppe

We are the world leader in forging manipulators for handling forgings on a press or hammer, loading and unloading furnaces, and transporting forgings between furnaces and forging units.

DANGO & DIENENTHAL is a company with a long tradition: founded in 1865 as a non-ferrous metal foundry by the craftsmen August Dango and Louis Dienenthal, it has since developed into one of the leading manufacturers of special machinery and equipment for steel mills, forging shops and the pipe industry. The product portfolio is supplemented by filter technology for the solid-liquid separation of media in almost all branches of industry.

Especially under extreme operating conditions, the machines from DANGO & DIENENTHAL work with the highest precision. Their robustness makes them highly available in production day in, day out and thus makes a decisive contribution to the efficient production processes of customers.

Since 2003, tapping technology and measuring technology have been the responsibility of TMT – Tapping Measuring Technology, a joint venture between DANGO & DIENENTHAL in Siegen and PAUL WURTH in Luxembourg.

The company HENCON BV, based in the Netherlands, has also been part of the group since the end of 2015 and completes the portfolio with special vehicles for the aluminum and mining industries.

As a family business, DANGO & DIENENTHAL thinks long-term: values such as quality and continuity are therefore attributed great importance. In the meantime, the DANGO & DIENENTHAL group of companies employs more than 850 people worldwide – some of them already in the fourth generation. In addition to the founding location in Siegen, DANGO & DIENENTHAL has subsidiaries with production and service locations in South Africa, North America, India, Japan, Russia, China, Mozambique and Sweden.

Today, the family-owned company is managed in the fifth generation by Rainer Dango and Arno Dienenthal. Since 2023, the management team has also been complemented by Dr. Jens-Uwe Heitsch and Alexander Neff.
