Bolting tool innovation and process quality


Continuous Improvement

With more than 30 years in the bolting industry, ITH continuously invests experience and know-how into new technical developments. Many designs that ITH developed are now industry standards.

More than 200 national and international patents prove the innovative capabilities of ITH.

Many of these developments have become standards of bolting technology.

Pioneer in Quality Management

ITH was the first in the market (1995) to introduce a Quality Management System, certified according to the strict specifications of ISO 9001-2008. This strong commitment to quality persists.

Technical and efficient economic benefit

We are continuously working to innovate and improve quality. Our customers benefit from technically optimized bolted joints and efficient, cost effective bolting tools.


 
 

Cooperation and development of standards

ITH has close partnerships with leading scientific institutions for the research and development of new bolting technology.

A lot of cooperative research and numerous succesful projects have already been completed. We are working together with the universities and insitutions RWTH Aachen, Ruhr University Bochum, Technical University Darmstadt, Technical University Dortmund, Fraunhofer Institute, ZeMA Saarbrücken, University of Applied Sciences Southwestfalia (at Meschede and Soest) and University of Applied Sciences in Zwickau.
Furthermore ITH contributes to the development of new technical standards within the German VDI (Association of German Engineers) and within the ISO (International Organization for Standardization).

ITH Autostretch: robot supported automation solution for Bolt Tensioning Cylinders

Application: Automatic tensioning of all bolt connections of wind turbines for high volume production (Bolting slew bearings to the hub).

  • Automatic identification of bolts with a 3D camera system and automatic processing
  • Automatic tensioning of bolt connections by Auto-BTC with safety management
  • Automatic control of hydraulic pumps with the ITH-APC-Control (Automatic Pressure Control)
  • The ITH Autostrech was developed with the Center for Mechatronics and Automatisation ZEMA in Saarbrücken.(Zentrum für Mechatronik und Automatisierungstechnik)
