RUD Ketten Rieger & Dietz GmbH u. Co. KG was founded in 1875 by Carl Rieger and Friedrich Dietz in Swabian Aalen. Since Friedrich Dietz’s departure, the company has been in the sole possession of the Rieger family who have systematically developed and expanded the organisation into today's successful international business.
Today, the RUD Group is a global player. Its main development and production facility in Aalen, offers future-oriented solutions with chain systems and components for a wide range of applications. In 1953 RUD were the first manufacturer of Chains to receive the H1 quality approval rating. Toward the end of the 1980’s the cornerstone for RUD’s quality management system ISO 9000 ff was completed, resulting in RUD becoming the first Chain Factory to obtain ISO 9001 Quality Assurance in 1992. The incorporation of QM and UM systems into RUD’s integrated Management manual was in 2000 and was certified by TÜV in 2001. As part of the output of the standards ISO 9001:2008 and ISO 14001:2005 the management manual has been updated to its present standing.
