In the rugged terrains of the Kolubara mining complex, Polytron products stood the test of time and extreme conditions. The narrative unfolds at the "Tamnava" West Field surface mine, where the colossal Bucket Excavator ERs 1000/20, a linchpin in coal extraction, faced the relentless challenge of wear and tear. The intervention with Polytron EP2 unguent and Polytron PL not only alleviated the immense stress on the angular ball bearings but also marked a turning point. From the meticulous overhaul in 2012 to the steadfast performance observed until 2014, the absence of stoppages or the need for interventions spoke volumes of Polytron's efficacy. This story isn't just about maintaining machinery; it's a testament to enhancing operational reliability and longevity in one of Europe's most demanding mining environments.
