Schmidt, Kranz & Co. GmbH
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. When the tractor market expanded in the late forties, fabrication of these products was shifted to Hattingen / Ruhr and NORMAG became a supplier to the new plant.
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.
Within the German reunification process, Schmidt, Kranz was able to repurchase their former plant in Nordhausen, Ullrichstrasse.

The production areas thrust boring technique, drill pipes according to API standards, drilling and injection technique remained in Walkenried at PERFORATOR.
Establishment and integration of mts Perforator Microtunnelling Systems based in Valluhn. Competences in tunneling technology and the human capital result mainly from the former LOVAT mts tunneling systems
Expansion of the production plant to raise the production capacity
Outsourcing of the Thrust boring branch to mts Perforator GmbH
Merger between mts Perforator GmbH Microtunnelling Systems and Perforator GmbH into mts Perforator GmbH to make processes more efficient as well as to profit from lean structures and synergies.
