singold gerätetechnik
Foundation and Early Years
In 1970, Dipl.-Ing. Erwin Lüer founded the company “singold gerätetechnik” in Hiltenfingen. The lack of suitable devices for bulk material plants led him to design and manufacture them himself.
Erwin Lüer invented and developed the world’s first pneumatic knocker of its kind. Patents were granted for both the singold gerätetechnik Pneumatic Knocker and Flap Shutter in the early years of operation. Even today – more than 55 years after their introduction – singold’s pneumatic knockers are the most efficient on the market.
Certified Quality
singold gerätetechnik meets the highest standards in quality management and customer-oriented processes. This has been confirmed by the DIN EN ISO 9001:2015 certificate.

Relocation and Further Successes

Relocation
In 1980, singold gerätetechnik moved to Schwabmünchen, south of Augsburg, into a new building constructed especially for the company. Since 1986, the company has been run under the legal form of a GmbH (limited liability company). In the same year, the highly specialised Double-Flap Sluice for Thyssen AG was delivered for the first time.

Modernisation & Expansion
In the mid-1990s, singold gerätetechnik gmbh switched to modern 3D CAD software and again expanded the business premises including the warehouse. In 1992 and 1996 followed special designs for other major customers, some of which are still in operation today.

Market Innovation
In 2020, a special version of the Distance Knocker QJ for the metallurgical sector was launched. In 2022, business activities focused on the mass rollout of the world’s largest and most powerful Pneumatic Knocker K160 in North America.
singold Today
The business is now run by Roswitha and Oliver Lüer, with Matthias Hofmann as technical director. The pneumatic knockers remain singold gerätetechnik gmbh’s best-selling product and have proven themselves in numerous industrial applications.
The product portfolio of pneumatic knockers in various sizes, strengths and designs is supplemented by pneumatic distance knockers, knocker accessories, flap shutters, double-flap sluices and rotary valves.
