History of a strong community


Foundation of the Schmidt, Kranz & Company. As supplier of the Central German potash mining industry, SK gained in importance. Manufacturing facilities and administrative buildings were built in Nordhausen.



The company was transferred into the possession of Prof. Dr. Karl Glinz. Due to a crisis in the potash mining industry. SK extended its product range with reprocessing plants and hydraulic engineering facilities according to patents of Prof. Dr. Glinz. In the early thirties the NORMAG tractor was successfully included into the program.



In December 1945 the NORMAG Zorge GmbH was founded and under the direction of Mrs. Cäcilie Glinz and Dr. Hans-Karl Glinz the production of spare parts for tractors and for the mining industry restarted.


Enlargement of the plant in Zorge. High pressure hydraulic systems, Tigrip-load-carrying equipment and Airator air cleaner were developed and successfully integrated into the product range.



The production of SK mining equipment was shifted to a new plant in Walkenried, later site of the PERFORATOR GmbH



Enlargement of the plant in Walkenried, all products are manufactured here except the high-pressure systems.
