Agricultural test rig
Overview

The load-bearing component structures of agricultural machinery are subjected to high stresses while travelling on the road and in the field. To ensure safe and reliable use by operators, especially during the harvest season, the manufacturers' simulation models can be validated and the design improved through fatigue tests on the laboratory's test rigs.

Thanks to state-of-the-art testing technology, both typical operational and individual load and stress scenarios can be realised.

Benefits
  • Dynamic forces up to 600 kN
  • Static forces up to 1 MN
  • Sinusoidal or ramp signals
  • Frequencies up to 2 Hz
  • Maximum dimensions of the fixing plate 13m x 4m
  • Magnetic particle testing of the test object
  • Task-specific test setups thanks to modular systems
  • Modern measurement sensors and technology
