Izikhathi zokuhola zama-oda evolumu ama-sprocket e-Hitachi EX300 ngokuvamile zisukela ezinsukwini ezingu-7-30 kuye ngokuthi ivolumu ye-oda kanye nendawo oya kuyo, kanye nekhono lokuhlinzeka ngezingcezu ezifika ku-10,000 ngenyanga.

Q10: Yiliphi i-torque okufanele lisetshenziswe kuma-bolts okufaka ama-sprocket?

Kuma-sprocket okushayela ekilasini le-EX300, ama-bolt okufaka (ngokuvamile ibanga le-10.9) kufanele afakwe i-torque ku-1,000–1,100 Nm (738–811 lb-ft) ngephethini ehleliwe, enezigaba ezintathu kusetshenziswa i-torque wrench elinganisiwe.

11. Isiphetho

Ama-sprocket amathathu e-Hitachi OEM cross-reference drive assemblies abhalwe kulolu hlaziyo—1022168, 71471228, kanye ne-AT202586—amelela izingxenye ezibalulekile zokudlulisa amandla ze-EX300-1, EX300-2, kanye ne-EX300-3 series hydraulic crawler excavators asetshenziswa ezimayini, ekumbeni, kanye nasemisebenzini yokwakha esindayo emhlabeni jikelele. Njengengxenye eyinhloko esebenzayo ohlelweni lwe-undercarriage, i-sprocket iguqula i-torque yokujikeleza yemoto yokugcina ibe amandla okudonsa aqondile aqhuba umshini, okwenza ubuqotho bayo bobunjiniyela bube yisisekelo ekuhambeni komshini kanye nokukhiqiza kokusebenza.

I-CQC TRACK (HELI MACHINERY MANUFACTURING CO., LTD.) ikhiqiza lawa ma-sprocket ukuze ahlangabezane noma adlule imininingwane ye-OEM ngokusebenzisa i-closed-die hot precision forging ethuthukisiwe, i-precision CNC machining, i-computer-controlled induction heat treatment, kanye ne-controlled quality authority procedure. Izinqubo zokukhiqiza eziqinisekisiwe ze-ISO 9001:2015 zenkampani, izinqubo zokuhlola eziphelele, kanye nesikhundla samasu njengomunye wabakhiqizi abathathu abaphezulu bezingxenye ze-undercarriage eqenjini lezimboni zemishini esindayo laseQuanzhou livumela ukuhlinzekwa okuqhubekayo ezimakethe zezimayini zomhlaba wonke.

Kwabasebenzi bezimayini, abathengisi bemishini, kanye nabasabalalisi bezingxenye kulo lonke elaseNingizimu Melika (eBrazil, eChile, ePeru), e-Australia (ePilbara, eQueensland, eNew South Wales), eYurophu (eJalimane, eFrance, eScandinavia), kanye naseRussia/e-Asia Ephakathi (eSiberia, eKazakhstan, eMongolia), lawa ma-sprocket ahlinzeka ngenye indlela ethembekile nengabizi kakhulu yezingxenye ze-OEM ngaphandle kokubeka engcupheni ikhwalithi yezinto ezibonakalayo, ukunemba kokukhiqiza, noma impilo yesevisi.

Ochwepheshe bokuthenga bakhuthazwa ukuqinisekisa ukuhambisana besebenzisa izinombolo zezingxenye ze-OEM ezinikeziwe, bacele imibhalo yekhwalithi efaka phakathi izitifiketi zezinto kanye nemibiko yokuhlola enobukhulu, futhi basungule ubudlelwano obuqondile bokuphakelwa nabakhiqizi abakhethekile ukuze bandise izindleko eziphelele zobunikazi bezimoto ezingaphansi kwe-Hitachi EX300-1/2/3. Kwabaphathi bemikhumbi kanye nabaphathi bokulungisa, ukusebenzisa uhlelo lokuhlola nokufaka esikhundleni se-sprocket olusebenzayo—kufaka phakathi ukulinganisa ukuguguleka kwamazinyo okuvamile, ukuqinisekiswa kwe-bolt torque, kanye nokushintsha kwe-sprocket-and-chain okuhlanganisiwe—kumele isu eliphumelela kakhulu lokukhulisa impilo yesistimu yezimoto ezingaphansi kwe-carriage kanye nokunciphisa isikhathi sokuphumula esingahleliwe.

Le ncwadi yobuchwepheshe ihloselwe ochwepheshe bobunjiniyela kanye nokuthengwa kwempahla embonini yezimayini kanye neyokwakha esindayo. Zonke izincazelo zingaphansi kokuqinisekiswa uma kuqhathaniswa nemibhalo yamanje ye-OEM. Ukuze uthole amanani amanje, izikhathi zokuhola, kanye nosekelo lobuchwepheshe, xhumana ne-CQC TRACK ngqo.
