I-PC75UU-3 inguqulo ethuthukisiwe yochungechunge lwe-UU enama-hydraulic athuthukisiwe, ukusebenza kwenjini okuthuthukisiwe, kanye nokonga uphethiloli okungcono. Emisebenzini emincane yasemadolobheni, amamodeli okujikijela angenamsila njengochungechunge lwe-PC75UU abekwa phambili. Kule mishini, i-drive sprocket kumele inikeze ukudluliselwa kwamandla okuthembekile ngaphansi kwezimo ezidinga kakhulu—kufaka phakathi imithwalo ye-torque, ukuthintana komhlaba okunamandla, kanye nokusebenza okuqhubekayo kokujikeleza—ngenkathi igcina ukubandakanyeka kwamazinyo okunembile ne-track chain.

Izinombolo zezingxenye ze-22E-27-11111 kanye ne-21W-27-31112 zibonisa ukuhambisana kwepulatifomu ehlukahlukene kuzo zonke izinhlobo ze-Komatsu PC75 kanye nokuhambisana kwemikhiqizo ehlukahlukene nemishini emincane ye-Yanmar ne-Volvo, okwenza la maqembu e-sprocket abe yizinto ezibalulekile zokubeka izinto kubaqhubi bemikhumbi abaphatha imikhumbi yemishini exubile.

I-CQC TRACK (HELI MACHINERY MANUFACTURING CO., LTD.) ikhiqiza lawa ma-sprocket ukuze ahlangabezane noma adlule imininingwane ye-OEM ngokusebenzisa ubuchwepheshe obuthuthukisiwe bokubumba obuvaliwe, ukucutshungulwa kwe-CNC okunembile, ukwelashwa kokushisa okulawulwa yikhompyutha okufinyelela ubulukhuni bendawo be-HRC 48-58 ngokujula kwekesi elingu-4-6 mm, kanye nezinqubo zokuqinisekisa ikhwalithi eziqinile. Izinqubo zokukhiqiza eziqinisekisiwe ze-ISO 9001:2015 zenkampani, izinqubo zokuhlola eziphelele, kanye nesikhundla samasu njengomunye wabakhiqizi abaphezulu bezingxenye zezimoto ezingaphansi kwenqola eqenjini lezimboni zemishini esindayo laseQuanzhou kuvumela ukuhlinzekwa okuqhubekayo ezimakethe zokwakha zomhlaba wonke.

Kwabathengisi bemishini, abaqhubi bemikhumbi yokuqasha, kanye nabasebenzisi bokugcina kulo lonke elaseNingizimu Melika (eBrazil, eChile, ePeru, e-Argentina, eColombia), e-Australia (eSydney, eMelbourne, eBrisbane, ePerth, e-Adelaide), eYurophu (eJalimane, eFrance, e-United Kingdom, eScandinavia), kanye neRussia/e-Asia Ephakathi (eMoscow, eSt. Petersburg, e-Astana, e-Almaty, eTashkent, e-Ulaanbaatar), lawa ma-drive sprockets ahlinzeka ngenye indlela ethembekile nengabizi kakhulu yezingxenye ze-OEM ngaphandle kokubeka engcupheni ikhwalithi yezinto ezibonakalayo, ukunemba kokukhiqiza, noma impilo yesevisi.

Kwabaphathi bezimoto kanye nabaphathi bokulungisa, ukusebenzisa uhlelo lokuhlola nokufaka esikhundleni izinyo ngokushesha—kufaka phakathi ukulinganisa ukuguguleka kwamazinyo njalo, ukuhlolwa kokuqhekeka kwezimpande, ukuqinisekiswa kwe-torque yebholiti, ukulungiswa okufanele kokucindezeleka kwethrekhi kube yi-15-30 mm sag, kanye nokufakwa esikhundleni kwezinyo ezihlanganisiwe—kumele isu eliphumelela kakhulu lokukhulisa impilo yesistimu yemoto engaphansi kwenqola kanye nokunciphisa isikhathi sokungasebenzi esingahleliwe emisebenzini yokwemba encane.

I-CQC TRACK iyakwamukela ngemfudumalo ukuthi wakhe ukubambisana futhi wakhe ubudlelwano obuhle besikhathi eside ndawonye.

Le ncwadi yobuchwepheshe ihloselwe ochwepheshe bobunjiniyela kanye nokuthengwa kwempahla embonini yokwakha, yokuqasha, kanye nengqalasizinda elula. Zonke izincazelo zingaphansi kokuqinisekiswa uma kuqhathaniswa nemibhalo yamanje ye-OEM. Izinombolo zokuqala zezingxenye ezisele zenzelwe izinjongo zokuqhathanisa kuphela. Ukuze uthole amanani amanje, izikhathi zokukhokha, kanye nosekelo lobuchwepheshe, xhumana ne-CQC TRACK ngqo.
