Test installation for spring characteristics measurement of KAGO rail contact clamps
Test installation for spring characteristics measurement of KAGO rail contact clamps
Due to their functional principle KAGO rail contact clamps must be flexible at all times. Also after being installed and removed repeatedly, the clamps must return in their original condition without permanent deformation.

To guarantee the needed elasticity KAGO rail contact clamps undergo – after the tempering procedure – a precisely determined load/stress test. For this reason a hydraulic test installation with integrated force-path-measurement is used. The clamp is stressed and released several times with a realistic pressure and then stretched past the elasticity limit. Irregularities due to production procedures or within the material are recognized immediately with this test.
