Kwimisebenzi exineneyo yasezidolophini, iimodeli ze-zero-tail swing ezifana noluhlu lwe-PC75UU zibekwe phambili. Kwezi matshini, i-drive sprocket kufuneka ibonelele ngokudluliselwa kwamandla okuthembekileyo phantsi kweemeko ezinzima—kubandakanya imithwalo ye-torque, unxibelelwano lomhlaba olurhabaxa, kunye nokusebenza rhoqo nge-cyclic—ngexesha igcina ukubandakanyeka kwamazinyo ngokuchanekileyo kwi-track chain.

Iinombolo zenxalenye ze-22E-27-11111 kunye ne-21W-27-31112 zibonisa ukuhambelana kwamaqonga ahlukeneyo kuzo zonke iintlobo zeKomatsu PC75 kunye nokuhambelana kophawu oluhlukeneyo nee-Yanmar kunye nee-Volvo mini excavators, nto leyo eyenza la maqela e-sprocket abe zizinto ezixabisekileyo kwi-inventory yabaqhubi beenqwelo-moya abalawula iinqwelo-moya zezixhobo ezixutyiweyo.

I-CQC TRACK (HELI MACHINERY MANUFACTURING CO., LTD.) yenza ezi sprockets ukuze zihlangabezane okanye zidlule kwiinkcukacha ze-OEM ngokusebenzisa ubuchwepheshe obuphezulu bokubumba obuvaliweyo, ukuchwetheza okuchanekileyo kwe-CNC, unyango lobushushu bokufakelwa olulawulwa yikhompyutha olufikelela kwi-HRC 48–58 surface hardness enobunzulu be-4–6 mm, kunye neenkqubo zokuqinisekisa umgangatho eziqinileyo. Iinkqubo zokuvelisa eziqinisekisiweyo ze-ISO 9001:2015 zenkampani, iinkqubo zovavanyo ezipheleleyo, kunye nendawo yobuchule njengomnye wabavelisi abaphambili bezinto ezingaphantsi kwesithuthi kwiqela lemizi-mveliso yoomatshini abanzima baseQuanzhou zivumela ukunikezelwa rhoqo kwiimarike zokwakha zehlabathi.

Kwabathengisi bezixhobo, abaqhubi beenqanawa zokuqeshisa, kunye nabasebenzisi bokugqibela kulo lonke elaseMzantsi Melika (eBrazil, eChile, ePeru, eArgentina, eColombia), eOstreliya (eSydney, eMelbourne, eBrisbane, ePerth, eAdelaide), eYurophu (eJamani, eFransi, eUnited Kingdom, eScandinavia), kunye neRussia/eCentral Asia (eMoscow, eSt. Petersburg, eAstana, eAlmaty, eTashkent, eUlaanbaatar), ezi sprockets zokuqhuba 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, ukusebenzisa ishedyuli yokuhlola i-sprocket kunye nokutshintshwa kwayo rhoqo—kubandakanya ukulinganisa ukuguguleka kwamazinyo rhoqo, ukuhlolwa kweengcambu, ukuqinisekiswa kwe-torque yebholiti, ukulungiswa koxinzelelo oluchanekileyo lwethrekhi ukuya kwi-15–30 mm sag, kunye nokutshintshwa kwe-sprocket kunye ne-chain edibeneyo—kumela icebo elisebenzayo lokwandisa ubomi benkqubo ye-undercarriage kunye nokunciphisa ixesha lokungasebenzi elicwangcisiweyo kwimisebenzi yokumba encinci.

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 kumashishini okwakha, okuqeshisa, kunye neziseko zophuhliso ezilula. 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.
