In 1963 Alfred Tüschen made the decision to found his engineering factory Tüschen & Zimmermann in a town called Lennestadt, located in Germany.
The company got specialized in drive combinations for applications in underground mining and decided to set their focus on the design of defined, mechanical interfaces between engines and gearboxes.
Torsionally flexible tz-couplings with length compensation, which allow the easy replacement of elastomers without the disassembling of the drive components, became an essential element of tz’s product line.
This modular design principle ensures the adaptability with individual drive elements.
The main application fields are the drive units of chain scrapers, plough systems, crushers and belt conveyors, hoists, pumps and other underground machinery.
This system is not only limited to form-fitting couplings, it also includes the versatile application options of fluid couplings.
This product line was extended through the development of brake and holding devices based on disc brake technology as well as chain tensioning devices for chain scrapers and plough systems.
tz-brake combination systems became a standard element concerning the shut down of belt conveyors and in view of the coasting security of chain scrapers and crushers.
