7.4 Ngā Aratau Rahunga me te Whakatau Rapanga

7.5 Ngā Tumanakohanga mō te Ora Ratonga

I raro i ngā āhuatanga keri keri noa me ngā āhuatanga hanga taumaha, ka taea e te roera raro ara kounga teitei e tutuki ana i ngā whakaritenga pakeke mata HRC 52–58 me te hohonu o te pouaka 6–12 mm te whakatutuki i ngā hāora mahi 3,000–5,000 i mua i te hiahia kia whakakapia. I roto i ngā tono keri keri nui me ngā rauemi tino whakakoi (te ihirangi silica > 30%) me te mahi tonu, ka taea te whakaiti i te roa o te mahi ki te 2,000–3,000 hāora mahi.

Mō te roa o te ora o raro o te waka, me tirotiro tonu, me whakakapi hoki ngā wāhanga roera hei pūnaha ina kitea he pakaru nui. Mā te whakaranu i ngā wāhanga kua pakaru me ngā wāhanga hou ka arahi pea ki te pakaru kore taurite, te hē o te tūnga, me te ngoikore o te mahi. Ko te tirotiro auau i te kume o te ara, te whakakapinga mekameka ara i te wā tika, me te whakahinuhinu tika ko ngā tikanga tino whai hua hei whakanui ake i te roa o te ora o te roera. Ko te korenga o tētahi roera raro kotahi i runga i tētahi keri 112–118 tana ka arahi pea ki te pakaru tere o te raro katoa o te waka, tae atu ki ngā hononga ara, ngā pine, ngā pū, me ngā porotiti, ā, ka tūpono pea ka he te ara—he huihuinga kino i roto i tētahi mahi keri e inehia ai te wā whakamutu i roto i ngā moni whiwhi whakaputa kua ngaro.

8. Te Hiranga o te Kōwhiringa Tika o te Roera Raro mō te Keritanga Akomanga Tino Pai

Ko te roera raro ara tētahi o ngā wāhanga tino taumaha i roto i te pūnaha raro o te waka keri. Kāore i rite ki ngā roera kawe, e tautoko ana i te wāhanga whakahoki ara o runga me te kawenga māmā, ka mau ngā roera raro i te taumaha katoa o te mīhini—tae atu ki te 118 tana mō te EX1200-7—me te whakahaere i ngā rerekētanga o te kume i te wā e whakateretere ana, e whakaroa ana, e huri ana. I roto i ngā mahi keri tuwhera, me tūtaki hoki ngā roera raro ki ngā rauemi tino koi, ngā rerekētanga pāmahana tino nui, me ngā huringa mahi tonu e whakatakoto ana i ngā tono tino nui ki runga i ia wāhanga raro.

Mō ngā keri Hitachi EX1200-6 me EX1200-7 e mahi ana i roto i te maina me te hanga taumaha—he mīhini kei te tata ki te 118 tana te taumaha mahi me ngā tono whakaputa o ia rā e inehia ana i roto i ngā mano tana—he mea nui te whiriwhiri i ngā roera raro ara kounga teitei me te whiriwhiri rauemi tika, te maimoatanga wera, ngā pūnaha hiri pakari, me te miihini tika.

Kei roto i te huihuinga roera raro ara 4666752 a CQC TRACK:

• Hanganga maitai whakarewa (40Mn2, 50Mn) mō te rere pai o te witi me te ātete pānga
• He mata rere whakapakeke-whakapūmau (HRC 52–58) me te hohonutanga o te pouaka 6–12 mm mō te ātete kakahu tino pai
• Te matua whakapakeketia (HB 280–350) e mau tonu ana te pakari ki te mimiti i ngā kawenga ru
• He peera roera whakarara kaha-teitei mō te huri pono i raro i ngā kawenga tino nui; i tīpakohia mō te kaha tino pai ki te whakahaere i ngā kawenga taumaha mai i te taumaha mīhini me ngā kawenga tuaka nui i te wā o te urungi me te mahi taha-piki.
• Pūnaha hiri maha-wāhanga (ngā parepare rūpahu, ngā hiri mata mānu, ngā hiri hinu NBR) e whakarato ana i te ārai parahanga pakari ki te paru, te onepu, me te makuku
• Ngā tukanga hanga kua whakamanahia e te ISO 9001:2015 me te whai i ngā wāhanga katoa
• 1 tau / 2,500 hāora whakahaere hei paerewa

Mā ēnei āhuatanga hangarau ka whakarite kia pono te ratonga a ngā roera raro ara e tiakina pai ana puta noa i te roanga o te hoahoa i roto i ngā taiao keri tino uaua o te ao. Hei tētahi o ngā kaihanga wāhanga raro waka e toru o te rohe o Quanzhou—he rōpū ahumahi matua mō te hanga mīhini taumaha—kua whakatūria e CQC TRACK ia hei kaiārahi i roto i te hoahoa me te hanga i ngā wāhanga raro waka keri ngokingoki taumaha.

9. Whakamutunga

Mō ngā kaiwhakahaere o ngā keri Hitachi EX1200-6 me EX1200-7 e whakamahia ana i roto i te keri maina, te keri rua, te hanga taumaha, me te neke whenua papatipu—112–118 tana ngā mīhini tino-akomanga me ngā tono whakaputa o ia rā e inehia ana i roto i ngā mano tana—ko te huihuinga roera raro ara e tohuhia ana e te nama wāhanga 4666752 he wāhanga tino nui e pā tika ana ki te roa o te mekameka ara, te whakaritenga o raro, me te wā mahi o te mīhini. Ko te tūāpapa EX1200, me tōna whānui hu ara 1,200 mm, 18 roera raro mō ia mīhini (9 mō ia taha), me te pūnaha hiko 567 kW, e whakatakoto ana i ngā tono tino pai ki runga i ia wāhanga raro—ngā tono ka taea anake te whakatutuki mā te whiriwhiri rauemi pakari, te hanga tika, me te hoahoa hangarau pakari.

He kaihanga motuhake a CQC TRACK e whakakotahi ana i ngā tohungatanga whakarewa neke atu i te rua tekau tau, te whakaurunga poutū o ngā tukanga hanga me te maimoatanga wera, me te tauira ratonga OEM/ODM takirua hei tuku i ngā wāhanga o raro e mahi pono ana i raro i ngā āhuatanga tino uaua. Me ngā whakatakotoranga rauemi tae atu ki ngā maitai koranu 40Mn2 me te 50Mn; te maimoatanga wera e tutuki ana i te pakeke o te mata rere HRC 52–58 me te hohonu o te pouaka 6–12 mm; te tiwhikete kounga ISO 9001:2015 me te whakamanatanga o te ao IQNet; me ngā pūnaha hiri maha-wāhanga matatau (ngā kaitiaki rūpahu, ngā hiri mata mānu, ngā hiri hinu NBR), ka whakaratohia e CQC TRACK ki ngā kaipupuri waka me ngā tohunga hoko he otinga hangarau e tutuki ana, e hipa ana rānei i ngā whakatakotoranga OEM.

Mā te tiki tika i te huihuinga roera raro ara Hitachi 4666752 mai i te wheketere, ka whiwhi ngā mahi keri me te hanga i te kounga ōrite, te tautoko hangarau tika, te utu whakataetae (30–40% ngā penapena ki te OEM), me te mārama o te whakahaere mekameka tuku—ngā āhuatanga e arotau ana i te utu katoa o te mana me te whakanui ake i te wā mahi o te mīhini i roto i ngā taiao mahi uaua o te ao.
