Fatigue Life Supervision of Structural Components of Open-Pit Machines

Grabowski P., Jankowiak A., Król R.

Structural components of open-pit machines are exposed to fatigue degradation caused by operational loading. Those machines are usually manufactured in piece production and their usage is very intensive. This paper presents the procedure based on the exploitation strategy of such machines according to their technical condition in notches (like welded joints, etc.). Loading data were acquired on the real open-pit machine – KWK 910 excavator.
