I-CQC TRACK (HELI MACHINERY MANUFACTURING CO., LTD.) yenza ezi roller zokuthwala ukuhlangabezana okanye ukudlula iinkcukacha ze-OEM ngokusebenzisa ubuchwepheshe obuphezulu bokubumba obuvaliweyo, iteknoloji yokuwelda yefriction yokudibanisa umzimba we-shaft-to-roller, i-precision CNC machining, unyango lobushushu bokufakelwa olulawulwa yikhompyutha olufikelela kwi-HRC 52–58 surface hardness enobunzulu be-5–12 mm case, iteknoloji yokutywina ephindwe kabini enoyilo lokuthambisa ubomi bonke, kunye neenkqubo zokuqinisekisa umgangatho eziqinileyo kubandakanya uvavanyo lokutywina emanzini kunye novavanyo lokuqengqeleka. Iinkqubo zokuvelisa eziqinisekisiweyo ze-ISO 9001:2015 zenkampani, iinkqubo zovavanyo ezipheleleyo, kunye nesikhundla sobuchule njengomvelisi wecandelo eliphambili le-undercarriage kwiqela lemizi-mveliso yoomatshini abanzima baseQuanzhou zivumela ukunikezelwa rhoqo kwiimarike zezemigodi kunye nezokwakha zehlabathi.

Kwabasebenzi bemigodi, abathengisi bezixhobo, kunye nabasasazi bezixhobo kulo lonke elaseMzantsi Melika (eBrazil, eChile, ePeru, eArgentina, eColombia), eOstreliya (ePilbara, eQueensland, eNew South Wales, eNtshona Ostreliya), eYurophu (eJamani, eFransi, eScandinavia, eMpuma Yurophu), kunye neRussia/eMbindi Asia (eSiberia, eKazakhstan, eMongolia), ezi roller zezithuthi zokuthwala umkhondo zibonelela ngenye indlela ethembekileyo nengabizi kakhulu kwiindawo ze-OEM ngaphandle kokubeka emngciphekweni umgangatho wezinto, ukuchaneka kokwenziwa, okanye ubomi benkonzo.

Kubaphathi beenqwelo-mafutha kunye nabaphathi bolondolozo, ukuphumeza uvavanyo lwe-carrier roller kunye neshedyuli yokutshintshwa kwe-carrier roller rhoqo—kubandakanya ukulinganisa ukuguguleka kwe-tread rhoqo kusetyenziswa ii-calipers, ukuqinisekiswa kwe-flange geometry, ukujonga ukuthembeka kwe-seal, ulawulo olufanelekileyo loxinzelelo lwendlela (20–40 mm sag), kunye novavanyo oluhambelanayo lwe-undercarriage—lumele icebo elisebenzayo lokwandisa ubomi benkqubo ye-undercarriage kunye nokunciphisa ixesha lokungasebenzi elingacwangciswanga kwimisebenzi yokwemba enzima kunye nokwakha. Ukutshintsha ii-carrier roller ngexesha lokuhlolwa kwe-undercarriage okucwangcisiweyo okanye nanini na xa kuvela iimpawu zokuguguleka—ngaphambi kokuba kubekho umonakalo omkhulu—kwandisa ixesha lokusebenza komatshini kunye nokusebenza kakuhle kweendleko.

I-CQC TRACK iyakwamkela ngezandla ezishushu ukuba nibe nentsebenziswano kwaye nidale ubudlelwane obuhle bexesha elide kunye.

Olu shicilelo lobuchwephesha lujoliswe kwiingcali zobunjineli kunye nokuthengwa kwempahla kwimizi-mveliso yezemigodi, yokwakha enzima, kunye nokuthutha umhlaba. Zonke iinkcukacha zixhomekeke ekuqinisekisweni kwamaxwebhu e-OEM akhoyo. Iinombolo zokuqala zezixhobo zenzelwe ukuthelekisa kuphela. Ngamaxabiso akhoyo, amaxesha okukhokela, kunye nenkxaso yobugcisa, nxibelelana ngqo ne-CQC TRACK.
