The Company

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.

Relocation and further successes

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. This was followed in 1992 and 1996 by special designs for other major customers, some of which are still in operation today.

In the mid-1990s, singold gerätetechnik gmbh switched to modern 3D CAD software and again expanded the business premises including the warehouse.

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.
