Connecting elements

Connecting elements which are used in the wind energy sector impose high requirements on the testing technology.
Screws with a size of up to M 72 can be stressed with a load of up to 3500 kN and can be pulled until fracture.
With the testing software standardized tests according to EN 6892 can be conducted and characteristic values such as Young's modulus, tensile strength, elastic limits, ... are determined.

The testing machine for this purpose is carried out in a frame construction rather than in the conventional column construction. This concept provides stability, robustness and safety for the operators.

In the article "Hochfeste Schrauben dynamisch geprüft" (German) one of our customers reports on his daily use of a testing machine as described above.
