Im modernen Tagebau spielen Stapel- und Entnahmemaschinen eine entscheidende Rolle beim Materialumschlag. Diese riesigen Maschinen sind f\u00fcr das Stapeln und Entnehmen von Sch\u00fcttg\u00fctern wie Kohle, Eisenerz und Bauxit zust\u00e4ndig. Ein typischer Stapel- und Entnahmebagger kann mehrere hundert Tonnen wiegen und Tausende Tonnen Sch\u00fcttgut pro Stunde bewegen \u2013 daher ist seine Betriebssicherheit entscheidend f\u00fcr die Kontinuit\u00e4t der Produktion. Einer der Bergbaukunden von Yongjian stand vor einem schwerwiegenden Problem: Ein wichtiges Lager in einem 470 Tonnen schweren Stapel- und Entnahmebagger musste aufgrund eines Erm\u00fcdungsbruchs ausgetauscht werden. Das Lager st\u00fctzte eine kritische Komponente der Schwenkbewegung. Jeder Ausfall h\u00e4tte direkte Auswirkungen auf den Materialverladeprozess und die Gesamtproduktivit\u00e4t gehabt. Eine hydraulische Steuerungsl\u00f6sung mit hoher Kapazit\u00e4t erm\u00f6glichte die pr\u00e4zise, synchronisierte Bewegung mehrerer Zylinder. Dieses System stellte eine Echtzeit-R\u00fcckmeldung und -Korrektur an jedem Hebepunkt sicher und gew\u00e4hrleistet so eine perfekte Parallelit\u00e4t w\u00e4hrend des Hebevorgangs.
