11. Isiphetho
Imishini yokumba i-Liebherr R974, R974B, R974C, kanye ne-R974C Litronic HD imelela izinga eliphakeme kakhulu lobunjiniyela baseJalimane esigabeni sokumba izimayini sezinga eliphezulu. Le mishini engamathani angu-80–90 isetshenziswa emisebenzini yokumba edinga kakhulu emhlabeni, lapho ukuthembeka nokuqina kuthinta ngqo inzuzo yokukhiqiza.
I-Track Idler Wheel Assembly (5000127 / 7365656) iyisici esibalulekile esiqondisa uchungechunge lwethrekhi yephimbo elingu-260 mm, ilawula ukucindezeleka kwethrekhi, futhi imunce imithwalo yomthelela ngenkathi isekela ingxenye enkulu yesisindo sokusebenza komshini. Ubunjiniyela be-idler—obuhlanganisa ukuqina kwe-induction okujulile (ukujula kwekesi elingu-8–12 mm), izinhlelo zokuvala izithiyo eziningi ngokunemba, kanye nokwakhiwa kwensimbi ye-alloy enamandla aphezulu—bulungiselelwe ngokukhethekile izidingo ezinkulu zezicelo zokumba.
I-CQC TRACK (HELI) iwumkhiqizi wezingxenye ze-EXC crawler ezisebenza ngaphansi kwenqola yokuthutha impahla ochwepheshe ohlanganisa konke okuqondile, ubunjiniyela bensimbi obuthuthukisiwe, izinqubo zokuqinisekisa ikhwalithi eziqinile, kanye nengqalasizinda ephelele yochungechunge lokuphakelwa komhlaba wonke. Izingxenye zethu zenzelwe ukuhlangabezana noma ukudlula imininingwane ye-OEM ye-Liebherr, equkethe:
- Ukwakhiwa kwe-closed-die ukuze kube nesakhiwo esihle kakhulu sokusanhlamvu kanye nokumelana nokukhathala
- Ukwelashwa kokushisa kwezakhiwo ezimbili okuhlanganisa umongo oqinile (280–350 HB) nendawo egugile (HRC 50–58)
- Ukuqina kokufakwa okujulile okunobubanzi bekesi obungu-8-12 mm ukuze kube nesikhathi eside sokusebenza kwezimayini
- Umshini wokulungisa ngokunemba one-±0.02 mm tolerances kuma-interface abalulekile
- Izinhlelo zokuvala izithiyo eziningi zokukhipha ukungcola ezindaweni ezibucayi
- Ukulandeleka okugcwele kwezinto ezibonakalayo ngeMill Test Reports kanye nesitifiketi
Lokhu kutshalwa kwezimali kobunjiniyela kuqinisekisa ukusebenza okuthembekile kuzo zonke izindawo zokusebenza ezidinga kakhulu emhlabeni—kusukela ezimayini zensimbi zase-Australia naseNingizimu Melika kuya emisebenzini yedayimane negolide yase-Afrika, kusukela ezifundeni zase-Russia ezineqhwa kuya ezindaweni zokumba imigodi zaseKorea, kanye nasesihlabathini sikawoyela saseCanada kuya emisebenzini yokumba eMpumalanga Ephakathi naseYurophu.
Ukuze uthole imininingwane yobuchwepheshe, imibuzo yamanani, noma ukufaka ama-oda ezingxenye ze-Liebherr R974 series undercarriage, xhumana nomnyango wokuthengisa wamazwe ngamazwe we-CQC TRACK ngenombolo yakho yochungechunge lomshini kanye nezidingo ezithile.
