4. Xhasa iSakhelo seNdlela: Beka ijeki ye-hydraulic enzima kunye neebhloko eziqinileyo phantsi kwesakhelo sendlela kufutshane nerola eza kutshintshwa.
5. Susa iiBholthi zokuFaka: Irola ibanjwa ziibholthi ezinkulu ezifaka intambo kwisakhelo somzila. Ezi zihlala ziqinile kakhulu kwaye zibola; ubushushu okanye isixhobo esinamandla sokutsala sidla ngokuba yimfuneko.
6. Faka iRoller Entsha: Susa indibano endala, coca umphezulu wokufakela, faka indibano entsha yeroller, kwaye uqinise iibholthi ezintsha ezixineneyo ngesandla. Sebenzisa iibholthi ezintsha rhoqo; ukusebenzisa kwakhona ezindala kuyingozi yokhuseleko.
7. I-Torque to Spec: Sebenzisa isikrufu se-torque esilinganisiweyo ukuqinisa iibholithi kwixabiso elichaziweyo lomenzi (oku kuya kuba yi-torque ephezulu kakhulu kumatshini walolu hlobo).
8. I-Re-tension Track: Phinda ucinezele i-track tensioner nge-grease gun ukuze ufikelele kwi-track sag efanelekileyo.
9. Qinisekisa Ukusebenza: Sebenzisa umatshini ngesantya esiphantsi kwaye uhlole ukujikeleza okufanelekileyo kwerola, ukuthembeka kwetywina, kunye nokulungelelaniswa komkhondo.

Izixhobo nezixhobo ezifunekayo: Ijeki ye-hydraulic enzima kunye neebhloko ze-cribbing eziqinileyo, isikrufu esinoxinzelelo oluphezulu okanye i-breaker bar enkulu eneziseko ezifanelekileyo, isixhobo sokuphakamisa (i-crane okanye ibhakethi ye-excavator) yokuphatha i-roller assembly enzima, kunye nezixhobo zokuzikhusela zomntu (PPE)—izihlangu ezineenzwane zentsimbi, iiglavu, iiglasi zokhuseleko.

7.3 Ishedyuli yoLondolozo

Ukucoca rhoqo indawo engaphantsi kwesithuthi ukuze kususwe ukungcola kunye nenkunkuma, kulandele ukuthambisa iindawo ezifuna ukuthambisa, kubalulekile ekunciphiseni umngcipheko wokonakala, ukwandisa ubomi beendawo ezingaphantsi kwesithuthi sokumba, kunye nokugcina ukusebenza kakuhle kwezixhobo. Kwiimashini ze-EX1200-6 kunye ne-EX1200-7 ezisebenza kwizicelo zokumba ngokuqhubekayo, ukuhlolwa kwemihla ngemihla kwesithuthi esingaphantsi kwesithuthi kuyacetyiswa ngenxa yeemeko ezirhabaxa ezifunyanwa kwimigodi evulekileyo.

7.4 Iindlela zokusilela kunye nokusombulula iingxaki

7.5 Ulindelo lobomi benkonzo

Phantsi kweemeko eziqhelekileyo zokumba imigodi kunye nokwakha okunzima, i-roller esezantsi ye-track esemgangathweni ehlangabezana neenkcukacha zobunzima bomphezulu we-HRC 52–58 enobunzulu be-case obuyi-6–12 mm inokufikelela kwiiyure zokusebenza ezingama-3,000–5,000 ngaphambi kokuba ifune ukutshintshwa. Kwizicelo ezinzima zokumba ezinezixhobo ezirhabaxa kakhulu (umxholo we-silica > 30%) kunye nokusebenza okuqhubekayo, ubomi benkonzo bunokwehliswa bube ziiyure zokusebenza ezingama-2,000–3,000.

Ukuze ufumane ubomi obufanelekileyo bokusebenzisa i-subcarriage, soloko uhlola kwaye utshintshe ii-roller components njengenkqubo xa kufunyenwe ukuguguleka okukhulu. Ukuxuba ii-substrate ezigugulekileyo nezintsha kunokukhokelela ekugugulekeni okungalinganiyo, ukungalungelelani kakuhle, kunye nokusebenza okunciphileyo. Ukuhlolwa rhoqo koxinzelelo lwe-track, ukutshintshwa kwe-track chain ngexesha elifanelekileyo, kunye nokuthambisa ngokufanelekileyo zezona ndlela zisebenzayo zokwandisa ubude be-roller. Ukungaphumeleli kwe-roller enye esezantsi kwi-excavator yeetoni ezili-112–118 kunokukhokelela ekugugulekeni okukhawulezileyo kuyo yonke i-subcarriage, kubandakanya ii-track link, ii-pins, ii-bushings, kunye nee-sprockets, kwaye kunokubeka umngcipheko wokuphazamiseka kwe-track-isiganeko esibi kakhulu kumsebenzi wemigodi apho ixesha lokungasebenzi lilinganiswa kwingeniso yemveliso elahlekileyo.

8. Ukubaluleka koKhetho olufanelekileyo lweRoller esezantsi kwiMigodi ye-Ultra-Class

Irola esezantsi yetrack yenye yezona zinto zixinzelelekileyo kakhulu kwinkqubo ye-excavator undercarriage. Ngokungafaniyo nee-carrier rollers, ezixhasa icandelo lokubuyela kwetrack ephezulu ngomthwalo olula, ii-bottom rollers zithwala ubunzima obupheleleyo bomatshini—ukuya kuthi ga kwiitoni ezili-118 ze-EX1200-7—ngelixa ngaxeshanye zilawula ukuguquguquka koxinzelelo oluguquguqukayo ngexesha lokukhawulezisa, ukucothisa, kunye nokujika. Kwimisebenzi yokwemba evulekileyo, ii-bottom rollers kufuneka zijongane nezinto ezirhabaxa kakhulu, utshintsho olukhulu lobushushu, kunye nemijikelo eqhubekayo ebeka iimfuno ezingaqhelekanga kuyo yonke into engaphantsi kwetrack.

Kwi-Hitachi EX1200-6 kunye ne-EX1200-7 excavators ezisebenza kwimigodi kunye nokwakha okunzima—oomatshini abanobunzima bokusebenza obufikelela kwiitoni ezili-118 kunye neemfuno zemveliso zemihla ngemihla ezilinganiswa ngamawaka eetoni—ukukhetha ii-track bottom rollers ezikumgangatho ophezulu ezinokukhetha izinto ezifanelekileyo, unyango lobushushu, iinkqubo zokuvala eziqinileyo, kunye nomatshini wokulungisa ngokuchanekileyo kubalulekile.

I-CQC TRACK's 4666752 track bottom roller assembly iquka oku kulandelayo:

• Ukwakhiwa kwentsimbi ye-alloy eyenziweyo (40Mn2, 50Mn) ukuze kubekho ukuhamba kakuhle kweenkozo kunye nokumelana nempembelelo
• Umphezulu wokubaleka oqiniswe yi-induction (HRC 52–58) onobunzulu bekheyisi eyi-6–12 mm ukuze ukwazi ukumelana nokuguguleka okugqwesileyo
• Umongo oqinisiweyo (HB 280–350) ugcina ukuqina kokufunxa imithwalo yoxinzelelo
• Iibheringi zerola ezithambileyo ezinomthamo ophezulu zokujikeleza okuthembekileyo phantsi kwemithwalo enzima; zikhethelwe amandla akhethekileyo okusingatha imithwalo enzima yeradial edibeneyo evela kubunzima bomatshini kunye nemithwalo emikhulu ye-axial ngexesha lokuqhuba kunye nokusebenza kwe-side-slope
• Inkqubo yokutywina enamanqanaba amaninzi (izikhuselo ze-labyrinth, izitywino zobuso ezidadayo, izitywino zeoyile ze-NBR) ezibonelela ngomqobo oqinileyo wokungcola eludakeni, esantini, nakumswakama
• Iinkqubo zokuvelisa eziqinisekisiweyo ze-ISO 9001:2015 ezinokulandelelwa ngokupheleleyo kwezixhobo
• Iwaranti yonyaka omnye / iiyure ezingama-2,500 zokusebenza njengesiqhelo

Ezi mpawu zobunjineli ziqinisekisa ukuba ii-track bottom rollers ezigcinwe kakuhle ziya kubonelela ngenkonzo ethembekileyo kuyo yonke imihla yazo yoyilo kwiindawo zemigodi ezifuna kakhulu ehlabathini. Njengomnye wabavelisi abathathu abaphambili bezixhobo ze-undercarriage kummandla waseQuanzhou—iqela eliphambili lemizi-mveliso yokwenziwa koomatshini abanzima—i-CQC TRACK izibonakalise njengenkokeli kuyilo kunye nemveliso yezinto ze-undercarriage excavator ezinzima.

9. Isiphelo

Kwabo basebenza kwi-Hitachi EX1200-6 kunye ne-EX1200-7 excavators ezisebenza kwimigodi, ekumbeni, ekwakheni izinto ezinzima, nasekuthuthweni komhlaba ngobuninzi—oomatshini be-112–118 ton ultra-class abaneemfuno zemihla ngemihla ezilinganiswa ngamawaka eetoni—i-track bottom roller assembly emelwe yinombolo yenxalenye 4666752 yinxalenye ebalulekileyo yomsebenzi wayo, ukuthembeka kwayo kuchaphazela ngokuthe ngqo ubomi be-track chain, ukulungelelaniswa kwe-undercarriage, kunye nexesha lokusebenza komatshini. Iqonga le-EX1200, elinobubanzi bezihlangu ze-track eziyi-1,200 mm, ii-rollers ezisezantsi ezili-18 ngomatshini ngamnye (ezi-9 kwicala ngalinye), kunye ne-powertrain engama-567 kW, libeka iimfuno ezikhethekileyo kuyo yonke i-undercarriage component—iimfuno ezinokufezekiswa kuphela ngokukhetha izinto ezingqongqo, ukuveliswa ngokuchanekileyo, kunye noyilo lobunjineli oluqinileyo.

I-CQC TRACK izichaza njengomvelisi okhethekileyo odibanisa ubuchule be-metallurgical obungaphezulu kweminyaka engamashumi amabini, ukuhlanganiswa ngokuthe nkqo kweenkqubo zokubumba kunye nonyango lobushushu, kunye nemodeli yenkonzo ye-OEM/ODM ephindwe kabini ukubonelela ngezinto ezingaphantsi kwesithuthi ezisebenza ngokuthembekileyo phantsi kweemeko ezinzima kakhulu. Ngeenkcukacha zezinto ezisetyenzisiweyo kubandakanya iintsimbi ze-alloy ze-40Mn2 eziphezulu kunye ne-50Mn; unyango lobushushu olufikelela kwi-HRC 52–58 yokubaleka komphezulu kunye nobunzulu be-case ye-6–12 mm; isiqinisekiso somgangatho se-ISO 9001:2015 esinokuqatshelwa ngamazwe ngamazwe se-IQNet; kunye neenkqubo zokutywina ezikumgangatho ophezulu (i-labyrinth guards, i-floating face seals, i-NBR oil seals), i-CQC TRACK inika abanini beenqwelo-moya kunye neengcali zokuthenga izisombululo ezenziwe ngobunjineli ezihlangabezana okanye ezidlula iinkcukacha ze-OEM.

Ngokufumana i-Hitachi 4666752 track bottom roller assembly ngqo kwifektri, imisebenzi yezemigodi neyokwakha ifumana ukufikelela kumgangatho ohambelanayo, inkxaso yobugcisa ethe ngqo, amaxabiso akhuphisanayo (ukonga okungama-30–40% xa kuthelekiswa ne-OEM), kunye ne-transparent supply chain logistics—izinto ezidibanisa ukuphucula iindleko zobunini kunye nokwandisa ixesha lokusebenza komatshini kwiindawo zokusebenza ezinzima kwihlabathi.
