Tools, Welding Design and Test Rig Technology

Tools and Welding Design

The fast and strong power increase of wind turbines during the last years leads to larger and heavier components. To handle these parts easy and also save the demand on special lifting, handling and manufacturing tools rise.    


eolotec offers the conception, design, stress calculation and purchasing of these customized tools. The customer will benefit of the long term experience and expertise in design and stress analyses. The design will be done under consideration of all leading international standards:         


- DIN 18800 und DIN-EN-1090 Steel structures and welding design
- DIN-EN-13155 Cranes - Non fixed load lifting attachments
- Guide to application of the Machinery 2006/42EG
- CE marking and declaration of conformity
- several international standards

Test Rig

After the production of new developed components or systems the products are usually tested on a test rig. Intensive pretesting allows to detect issues as early as possible, thus allowing to solve time. The challenge is to reproduce the reality as good as possible and in addition to receive repeatable results. Because of the large size of modern wind turbines and the high dynamics of the loads it is challenging to meet these requirements.

eolotec knows about the critical operation conditions and works on new test rig solutions, which allow testing of critical situations for gears and bearings.

For this purpose eolotec cooperates with a partner, which has long year experience in the design and manufacturing of test rigs for the wind industry.
