9. Isiphetho

Kwabasebenza ngemishini yokumba i-Hitachi ZX870-3LC esetshenziswa ezimayini, ekumbeni, ekwakheni okunzima, nasekuthuthweni komhlaba ngobuningi—umshini we-ultra-class ongu-80-90 ton onezidingo zokukhiqiza zansuku zonke—i-track upper roller/carrier roller assembly emelelwe yinombolo yengxenye 4638433 iyinto ebalulekile emsebenzini wayo, ukuthembeka kwayo okuthinta ngqo impilo yeketanga lomzila, ukulungiswa kwemoto engaphansi kwemoto, kanye nesikhathi sokusebenza komshini. Le ngxenye ihambisana ngokugcwele ne-ZX850-3, ZX870-5B/5G, ZX890-5A, EX1200-6, kanye namapulatifomu okumba ahlobene nawo, okunikeza ukusetshenziswa okubanzi kulo lonke uhlu olukhulu lwemishini yokumba i-Hitachi.

I-CQC TRACK izihlukanisa njengomkhiqizi okhethekile ohlanganisa ubuchwepheshe bensimbi obungaphezu kweminyaka engamashumi amabili, ukuhlanganiswa okuqondile kwezinqubo zokubopha kanye nokwelashwa kokushisa, kanye nemodeli yesevisi ye-OEM/ODM ekabili ukuze ilethe izingxenye ze-undercarriage ezisebenza ngokwethembeka ngaphansi kwezimo ezidinga kakhulu. Njengomunye wabakhiqizi bezingxenye ezintathu eziphezulu ze-undercarriage esifundeni saseQuanzhou, i-CQC TRACK izibonakalise njengomholi ekwakhiweni nasekukhiqizweni kwezingxenye ze-undercarriage excavator ezisindayo.

Ngezincazelo zezinto ezibonakalayo kufaka phakathi izinsimbi ze-alloy ze-50Mn, 40Mn2, kanye ne-42CrMo ze-premium; ukwelashwa kokushisa okufinyelela ubulukhuni bomphezulu ogijimayo be-HRC 55-60 obunobubanzi bekesi obungu-6-12 mm kanye nobunzima be-core ye-HRC 28-35; izinhlelo zokuvala ezithuthukisiwe ezinezigaba eziningi (ama-labyrinth guards, ama-floating face seals, ama-NBR oil seals); kanye nesitifiketi sekhwalithi se-ISO 9001:2015, i-CQC TRACK inikeza abanikazi bemikhumbi kanye nochwepheshe bokuthenga izixazululo ezithuthukisiwe ezihlangabezana noma ezidlula izincazelo ze-OEM.

Ngokuthola i-Hitachi 4638433 track upper roller assembly ngqo kusuka efektri, imisebenzi yezimayini kanye nokwakhiwa ithola ukufinyelela kwekhwalithi ehambisanayo, ukwesekwa okuqondile kwezobuchwepheshe, amanani okuncintisana (ukonga okungu-30-40% uma kuqhathaniswa ne-OEM), kanye ne-supply chain logistics esobala—izinto ezihlanganisa ukwandisa izindleko zobunikazi kanye nokwandisa isikhathi sokusebenza komshini ezindaweni zokusebenza ezinzima kakhulu emhlabeni.

Umbhali: uJack
Ngingochwepheshe ezinhlelweni zemishini esindayo, ukuthembeka kwemishini yezimayini, kanye namasu okuthola ulwazi emhlabeni wonke ngemikhumbi yemishini yokwakha.

Isixwayiso: Le ncwadi iwukuqukethwe kokuqala okwenzelwe izinjongo zolwazi kanye nezinkomba zobuchwepheshe. Zonke izinombolo zomkhiqizo, amagama omkhiqizo, kanye nezinkomba zomkhiqizi zisetshenziselwa ukuhlonza kanye nokubhekisela kuphela. Njalo qinisekisa ukuhambisana nenombolo yochungechunge yomshini wakho kanye nokucushwa kwenqola engaphansi kwemoto ngaphambi koku-oda. Izinqubo zokufaka ezifingqiwe kusukela ezindinganisweni zomkhakha zinikezwa ukuze zibhekiselwe; bheka imibhalo ephelele yemishini yokuqala ngaphambi kokwenza noma yikuphi ukulungiswa. Ulwazi lwewaranti luyimfanelo futhi lungaphansi kokuqinisekiswa nomkhiqizi ngesikhathi sokuthenga. UHitachi uncoma ukuthi kushintshwe wonke ama-roller aphezulu kokubili ezindleleni zesobunxele nesokudla ngesikhathi esisodwa ukuqinisekisa ukusebenza okulinganayo kwenqola engaphansi kwemoto kanye nokuhambisana kwenqola.
