Bolted joints on engines: Bolting tools and solutions

Bolted joints on engines: Bolting tools and further bolting solutions

For manufacturers of large diesel and gas engines ITH supplies a complete range of individual bolting tools (for example bolt tensioning cylinders type twin), lifting devices, extraction tools or other industry specific solutions. These projects led to significant cost and time savings for our business partners.

Bolted joints on diesel and gas engines are subjected to high dynamic stresses during operation. Therefore bolt connections have to be tightened very accurately and evenly with the ITH Stretch-Method. Additionally ITH recommends using the digital documentation system PD / PSD to control and document the bolting procedures automatically.

Find an example overview of all applications and relating ITH bolting solutions for bolted joints on engines below.
