Ka tohua e ngā Kaiwhakahaere Tiaki Rōpū Keri Keri ngā Wāhanga GET me ngā Tapa Tapahi Whakapakari mō ngā Mahi Pana Bulldozer me te Whakawātea Mata Toka

Ina arotakehia e ā mātou kaiwhakahaere tiaki waka keri rua ā rātou whakapaunga taputapu ki te whakamahi i te whenua, ehara i te mea ko ngā wāhanga pakaru e kitea ana te nuinga o te tahua — engari ko te utu whakakotahi ote whakakapinga o ngā mata tapahi, te hanga anō i te kakau ripper, me te wā kore mahi o te bulldozeri ngā mahi pana me te whakawātea i te mata o te toka.NGĀ WĀHI KI TE WHAKAMAHI (Ngā Utauta Whakauru Whenua) me ngā mata tapahi whakapakekekua tohua inaianei hei pūnaha kakahu kua taungahia, nā te mea i runga i te mata o te toka pupuhi ka tangohia e te mata tapahi, te pito pito, me te pito ripper he wāhanga rerekē o te kawenga pānga; nō reira, ina whakapakeketia tetahi, ā, kāore ētahi, ko te hononga ngoikore te mea e tohutohu ana i te huringa whakakapinga katoa. I roto i ā mātou mahi whakarewa me te mahi ratonga mara mai i te tau 2010, kua tirotirohia e mātou te tikanga kakahu me ngā rau o ngā kaiwhakahaere tiaki, ā, kua tuhia e mātou ngā kōwhiringa koranu e whakahaerehia ana e mātou, te matihiko hototahi mō ngā waitohu OEM nui, me ngā raraunga utu-mō-ia-tana e kohia ana e mātou mai i ngā keri kohatu whakahiato me te rahi puta noa i te Tonga-Rawhiti o Āhia, Awherika, me Amerika ki te Tonga. I roto i tēnei aratohu ka tohaina e mātou taua tinana mahi kia taea ai e koe te whakamahi tika ki tō ake whakaritenga waka.

He aha te mārō o te taha tapahi e tautuhi ana i te huringa kakahu GET katoa

I roto i tētahi mahi pana i te rua kohatu e arotakehia ana e mātou, e 60-70 ōrau o te huringa mahi e pau ana i tētahi bulldozer akomanga D7, D8 rānei ki te neke i tētahi papa pokepoke kua utaina ki runga i te toka pakaru. Ko te mata tapahi anake te wāhanga e pā tonu ana ki te paepae, nō reira e whakapono ana mātou ko tōna pakeke te mea e whakatau ana i te wā tiaki katoa. Nā te mea ka kitea te taha e te pakū tonu o ngā tinana-rua me te pānga tinana-tuatoru mai i ngā kohatu kua tanumia,Ko te maitai waro-waenga noa (tata ki te 32-38 HRC) ka pakaru i te tere tata-rārangi o te 0.8-1.2 mm ia 100 hāora mahi i roto i te toka pere karāhe, engari ko te mata maitai boron kua whakapakeketia i te 48-52 HRC ka heke iho taua tatauranga ki te 0.35-0.55 mm ia 100 hāora i roto i tā mātou kahui tohutoro. Kua kite mātou i te whakarea kotahi e mau ana puta noa i ngā rua keri e mahi ana mātou i Fujian, Riyadh, me Hanoi, ā, inaianei ka whakamahia e mātou te 2.1x hei pūtake whakamahere, kaua ki te tau hokohoko o runga e kīia tonutia ana e ētahi kaiwhakarato.

Kua inehia e mātou tēnei rerekētanga i runga i ngā whenua rerekē e toru ināianei, ā, kei roto tonu te ōwehenga i tētahi awhe whaiti. I roto i tā mātou whakamātautau i te rua kōhatu o Fujian i te tau 2023, i whakahaerehia e mātou he whakataurite taha-ki-taha i runga i ngā waeine D7R e rua rite tonu mō ngā hāora mahi 1,800. I tae te taha waro papatahi ki tōna rohe aukati-mau 25 mm i te 1,140 hāora, i te mea ko te taha whakapakeke 30MnB5 kei te 18 mm tonu o te matotoru e toe ana i te tohu hāora kotahi. I kumea e mātou ngā taha e rua i te tohu hāora 2,360, ā, i whiti te taha whakapakeke i tōna rohe mau; i inehia e mātou te 2.07x pea te roa o te ora o te taha waro i roto i te toka paepae kotahi. I whakahokia e mātou te whakataurite i runga i tētahi paepae basalt i te Tai Tokerau o Vietnam i te tau 2024, ā, i kite mātou i te 2.18x; i runga i tētahi paepae kōhatu pakaru i te Rawhiti o Saudi Arabia i te tīmatanga o te tau 2025 i inehia e mātou te 1.94x. E whakapono ana mātou ko te ōritetanga te mea e whakawhirinaki ai ō mātou kiritaki ki te kōpaki 1.8-2.4x e whakahuatia ana e mātou, nā te mea ka taea e mātou te tautoko i aua raraunga, kaua ki tētahi pukapuka iti.

Ko tā mātou i ako ai puta noa i tā mātou waka tohutoro 2018-2025, ko ngā kaiwhakahaere tiaki e whakamahi ana i te mata tapahi hei mea pau motuhake ka utu i te utu huna mō te roa o te urutau me te roa o te moka pito. He māmā noa te take, ā, ka ārahi mātou i ia kiritaki mā roto i tēnei mahi: ina pakaru te mata i te tuatahi, ka huri te kaiwhakahaere i te mata hei whakahoki i te urunga, ka utaina ngā moka pito ki te taha, ka tahuna mā roto i a rātou i te 30-40 ōrau te tere. I kite mātou i tēnei tauira e whakahokia ana i roto i ngā keri motuhake e whā i te tau 2024, ko ia o ēnei i whakapai ake i te mata tapahi anake, ā, i waiho ngā moka pito taketake ki tōna tūranga. Kua hangaia anō e mātou te whakatakotoranga mō ngā waka e whā mai i taua wā. Mā te tohu i tētahi mata whakapakeke e ōrite ana ki te pakeke o te moka pito, ka noho ōrite te mua o te kakahu mai i te pito ki te pito, ā, ka taea e te kaiwhakahaere te pupuri i te mata i te koki hoahoa mō te nekehanga katoa. Kua mātakitaki ahau i ngā kaiwhakahaere e whawhai ana ki tētahi mata kāore i te ōrite mō te nekehanga katoa, ā, ka taea e au te kī atu ki a koe ko te reo o te tinana e kōrero ana ki a koe i ngā mea katoa ka whakaūhia e te caliper i te ata e whai ake nei. Inaianei kei roto i tēnei tirohanga i roto i ia tono ka tukuna e mātou.

E rua ngā matapae taha e whakahaerehia ana e tā mātou whare hanga kohatu i Ningbo, ā, e harikoa ana mātou ki te whakapuaki i te tunu ki tētahi kaiwhakahaere tiaki e pātai ana: he maitai boron 30MnB5 mō te taunga whakakī me te 35MnB5 me te huringa wai-whakamātautau mō te mahi toka pupuhi parakore. Ka whakatauritea ngā mea e rua ki te 880-910 nekehanga Celsius i mua i te tineia, koinei te mea e pupuri ana i te matua ki te 380-420 HB i te wā e pana ana i te mata ki roto i te awhi 48-52 HRC e tonoa ana e ā mātou kiritaki keri kohatu. Ka whakatauritea e mātou ia wāhi wera nā te mea kua kite mātou i ngā taha maitai boron kāore i whakatauritea e whakawhanake ana i tētahi paparanga martensite pakarukaru i te mata e pakaru ana i roto i ngā haora 50 tuatahi i runga i te paepae kōhatu pakaru - he aratau rahunga e tohuhia ana e mātou i roto i tā mātou kawa tirotiro hou. Ka ārahi tā mātou tīma tukatuka-wera i tētahi arotake mua-tuku e rima-taahiraa mō ia wāhi, ā, kua rua ā mātou whakakorenga i ā mātou ake oma whakaputa i roto i ngā marama 18 kua hipa, kaua ki te tuku i tētahi mata taha. He pai ake ki a mātou te hanga anō i tētahi wāhi i te tiaki i tētahi pakaru, ā, ka kōrero mārama mātou ki ā mātou kiritaki.

Te Taunekeneke o te Mata Tapahi Kua Whakamārōhia ki ngā Mata Ripper me ngā Momo Pito i te Wā e Whakawātea ana i te Mata o te Toka

He mahi ranu te whakawātea i te mata o te toka. Ka mātakihia e mātou tēnei huringa i roto i ngā keri a ā mātou kiritaki i ia hauwhā, ā, he tino ōrite te raupapa puta noa i ngā rohe: ka pana tuatahi te dozer i te matimati wetekina, kātahi ka haehae i te pakitara teitei kia taka te rahi rawa atu, kātahi ka hoki ki te pana i te para ki te putanga uta. I te wā o te rip pass,TIKINA ngā wāhanga o ngā kakau ripper — te pito ripper, te tiaki kakau, me te pupuri pine — ka mimiti i te kawenga pānga teitei ka neke atu i te 2,400 kN i runga i te D8 niho kotahi.. Kāore te mata tapahi, e mau ana ki te papa pokepoke, e kite i taua tihi; engari, ka taea e ia te whakahaere i te pao pumau o te pana i muri i te ripe. Nā te mea ka wehea ngā rohe mahi e rua i te wā engari ka honoa i roto i te huringa, ka tūtohu mātou kia tohua te ripper GET kia kotahi te taahiraa pakeke ngawari atu i te mata tapahi - ko te tikanga he 44-46 HRC i te pito ripper, 48-52 HRC i te taha.

Ka aroturukihia e mātou te taumahatanga ru nui i runga i ngā pito o te ripper mā te telemetry ine taumahatanga i ngā wā katoa e whakaaetia ana e te kiritaki, ā, e whakaatu ana ngā raraunga ka taea e ngā mirihekona 80 tuatahi o te whiu ripper kua mutu te piki ki te toru ngā wā o te kukume o te pae kume pumau. I roto i tā mātou pae tohutoro basalt o Te Tai Tokerau o Vietnam i te tau 2024, i tuhia e mātou tekau mā whitu ngā pikinga pēnei i roto i te nekehanga kotahi 11-hāora, ā, ko ia pikinga he tohu pakaru pea mō te pito kua whakapakeketia rawatia. I muri i tā mātou tautuhi anō i taua waka ki te 45 pito ripper HRC ki te 50 mata tapahi HRC, ka heke te tere pakaru o te pito mai i te kotahi mō ia 38 hāora mahi ki te kotahi mō ia 240 hāora mahi. I noho tahi mātou me te kaiwhakahaere tiaki i te mutunga o te whakamātautau, ā, i kī mai ia ki a mātou koinei te hauwhā tuatahi o tana mahi ono tau kāore he hanga anō ripper i te Rāhoroi, ā, kei te whakamahia e mātou taua pae hei paearu mō te whakaora i te pito pakaru. Ka tohaina e mātou te kauwhata telemetry katoa ki tetahi kiritaki e pātai mai ana, nā te mea e whakapono ana mātou he kaha ake te whakapati i ngā raraunga i tetahi whakatairanga hoko ka taea e mātou te tuhi.

I roto i ā mātou tirotirohanga mara, ko te momo rahunga e kitea ana e mātou i te nuinga o te wā ina pekehia e te rua keri tēnei ture pakeke-taurite ko te whati o te pito ripper kaua ko te kakahu. He maha ngā wā kua tuhia e mātou tēnei tauira, ā, inaianei ka kitea te mata whati mā te tirohanga. Kua whakapakeketia rawatia te pito kia "roa ake te mau," engari nā te mea he ngohengohe te mata tapahi i muri iho, ka kaha ake te pana a te kaiwhakahaere, ka poto te huringa ripper, ā, ka pakaru te pito pakarukaru ki te nohoanga urutau. Ko tā mātou akeRaupapa-J a CaterpillarmeRaupapa-K a CaterpillarKo te tikanga o te whakakapinga o ngā pito ko te 44-46 HRC mō tēnei take tonu — he teitei hei ātete ki te pakū, he iti hei ora i te whiunga o te pakaru. Kua tirotirohia e mātou ngā rau o ngā pito whati i roto i ngā tau e rima kua pahure ake nei, ā, kua mōhio mātou ko te pūtake o te pakaru i roto i te 80 ōrau o ngā take e hoki ana ki tētahi pito kua tino whakapakeketia me tētahi taha kāore i te tino whakapakeketia. E whakapuakina ana e mātou taua tatauranga 80 ōrau, nā te mea e hiahia ana mātou kia whakahē ngā kaiwhakahaere tiaki i tētahi kaiwhakarato e whakahua ana i tētahi pito ripper 52 HRC me te kore e whakamārama i te utu. Ka hoatu e mātou ki ā mātou kiritaki ngā kupu hei whakamahi.

He aha ngā Whakatakotoranga mō te Koranu me te Whakamahana-Mateatea me tono e koe mai i tētahi Kaiwhakarato Matapihi GET

Kāore e ranea te pepa whakaritenga e whakarārangi ana i te "mata tapahi whakapakeke". I roto i ā mātou arotake hoko, ka kite tonu mātou i ngā kaiwhakarato e tuku ana i te mea e rite ana ki te hua tika i runga i te pepa engari kāore i tutuki te utu mō te mahi keri i roto i ngā haora mahi tuatahi e 400. Kua pāngia mātou e aua hapa i te taenga mai o ngā kiritaki ki a mātou i muri i tētahi wheako tuatahi kino, ā, kua ako mātou ki te tohe ki te whai i ngā whakaritenga i raro nei. Ka tūtohu mātou i tētahi whakaritenga iti rawa e whā ngā rārangi mō ngā hoko keri hou katoa, ā, ka whakaputaina e mātou tēnei ki ā mātou kāri raraunga tuku kia taea ai e ngā kaiwhakahaere keri te arotake i te wera e haere mai ana:

• Te taumata maitai turanga: 30MnB5, 35MnB5 rānei te maitai boron mō iaISO 683-2he pae hurihuri wera, me te awhe waro o te 0.27-0.35 ōrau me te boron i te 0.001-0.003 ōrau. Ka whakahē mātou i ngā wera e taka ana i waho o tēnei awhe nā te mea ka kore e taea te matapae i te urupare whakapakeke.
• Te hohonutanga o te whakapakeketanga: iti rawa 12 mm i te 48 HRC, i inehia mā te Vickers traverse i ngā pikinga 1 mm mai i te mata kua pakaru, kaua mai i te mata i tukuna. Ko tā mātou tikanga whakamātautau ā-roto e whai ana i teNgā aratohu tahuritanga mārō a te NISTmō te whakatikatika tauine-maha, ā, kua kite mātou i te 30 ōrau o ngā rauemi e tae mai ana mai i ngā kaiwhakarato hou kāore i eke ki tēnei tirotiro i te tukunga tuatahi.
• Te whitiki mārō o te mata: 48-52 HRC i te mata tapahi, 44-46 HRC i ngā pito ripper, me te manawanui +/- 2 HRC i waenga i ngā rota. Ka ine mātou i runga i te mata whenua, kaua i runga i te kiri kua whakarewaina, nā te mea ka pānuihia he iti rawa te paparanga kiri kua tangohia te waro.
• Pānga Charpy: te iti rawa 27 J i te -20 nekehanga Celsius i runga i te Charpy V-notch roa mō iaASTM A370, nā te mea he nui ake te utu mō te mata mārō e pakaru ana i te pānga tuatahi o te kohatu i te mata ngohengohe e pakaru ana. Kua kite tātou i ngā mata i te 52 HRC e heke ana ki te 8 J pānga i te -20 C, koinei tonu te huinga e pakaru ana i te pānga tuarua.

Ka whakahaerehia e mātou he tirotiro Brinell 100 ōrau i ngā wāhi e toru i ia taha whakarewa i mua i tōna wehenga atu i te papa whakarewa, ā, ka puritia e mātou he tauira o ia wera mō ngā tau e rua kia taea ai e mātou te tango i te tauira me te whakamātautau anō mēnā ka pāngia te rua kohatu e tētahi tauira kakahu rerekē i roto i ngā marama e ono o te pakanga, kaua e tautohetohe mai i te mahara. Ka whakawhitihia hoki e tā mātou tīma QA ia tuku ki teANSI B30.20te paerewa whai i te tau wera kei runga i te tiwhikete mira kia rite te tau wera kua tāia ki te tau wera kua tāia ki te wāhanga. I ako mātou i tēnei tikanga i muri i tētahi aituā i te tau 2022 i whiwhi ai tētahi rua kohatu i tētahi uta whakauru mai i ngā wera e rua, ā, kāore i mārama te tauira kakahu tae noa ki te wā i rapua ai e mātou te āputa whai i te wā me te tīma tiaki a te kiritaki. Inaianei ka tukuna e mātou ia pouaka me tētahi kāri raraunga waehere-pae e matawai tika ana ki roto i te rārangi tiaki a te kiritaki, he mea iti noa iho tae noa ki te wā e ngana ana koe ki te mahi i tētahi arotake kakahu e ono marama te roa me te kore taua mea. Kāore e taea e mātou te whakaaro ki te hoki ki te pūnaha pepa-anake tawhito.

Hototahi ki a Caterpillar, Komatsu, JCB, Doosan, me Volvo: He aha ngā mea e tau ana me te kore he whakarerekētanga mara

Ko tētahi o ngā pātai e tino pā ana ki te kaiwhakahaere tiaki i te rua kohatu, he hou ki tā mātou raina hua, ko te mea ka uru ā mātou taha kua whakapakeketia me ngā wāhanga GET ki ngā mīhini o nāianei me te kore e mahi anō i te urutau. He rau ngā wā kua whakautua e mātou tēnei pātai, ā, kua whakatau mātou ki tētahi putanga poto: āe mō ngā mīhini kua whakarārangihia i raro nei, mena ka noho tonu koe i roto i ngā awhe raupapa kua tuhia, ā, kāore mō ngā mīhini i waho o aua awhe me te kore he arotake hangarau. Kua hē mātou ki te whakaaro he whānui ake te awhe hototahi i mua, ā, kua utua e mātou i roto i ngā hāora mahi anō; ka taea e te utu mahi anō i runga i tētahi taha kāore i te tika te neke atu i te uara ota katoa, nō reira ka whakawhanuitia e mātou ia utu ki te awhe raupapa mīhini e whakaratohia ana e te kiritaki. Ka tohe mātou ki tēnei whānuitanga nā te mea nō mātou te putanga.

Ka taea e koe te tirotiro i te rārangi katoa kua tohua mōHototahi ki a Caterpillarngā wāhanga me ngāHototahi ki Komatsungā wāhanga kei runga i ā mātou whārangi hua, ā, kua whakarāpopototia te whānuitanga o ā mātou whakakapinga ki runga i terārangi hua matuaMō ngā raraunga whakauru motuhake a OEM tae atu ki te taipana pūtu, te whakatakotoranga o te topenga pupuri, me te diameter o te pine kakau, ka tukuna atu e mātou ia ota me te kāri whakauru kua tāia; ka taea hoki e koe te tono i tētahi kape matihiko mai i tā mātoutīma whakapāi mua i te tuku i tētahi ota whakamātautau. Kua whakauruhia e mātou ngā tau wāhanga Komatsu D65 me D85 ki roto i tā mātou pātengi raraunga whakawhiti-tohutoro i ngā marama 12 kua pahure ake nei nā te mea i whiwhi tonu mātou i ngā tono mai i ngā kaiwhakahaere whānui o Āhia ki te Tonga-Rawhiti e whakahaere ana i ngā waka whakauru, ā, i hiahia mātou ki te hoatu ki a rātou he kāri raraunga kotahi hei utu mō te puranga rapu. Ka taea e mātou te mahi i te taua mea mō ngā mīhini Volvo me JCB mēnā kei roto i tō waka aua waitohu.

Ko tā mātou tūtohutanga kia tīmata mā te whakamātautau kotahi-mīhini, ā, kua whakatikatikaina e mātou tēnei huarahi mā roto i ngā whakamātautau maha a ngā kiritaki: kotahi huinga o ngā taha, kotahi huinga o ngā pito ripper, kotahi huinga o ngā pito pito i runga i te mīhini akomanga D7, D8 rānei kotahi, me ngā wāhanga kakahu o nāianei e puritia ana i runga i te mīhini tuahine hei mana whakahaere. I muri i te 500 hāora whakahaere, tōia ngā huinga e rua ka ine. I roto i ō mātou wheako, ka kitea te rerekētanga i runga i te huinga tuatahi o ngā ine caliper, ā, ka tuhia te take ōhanga ki roto i te nekehanga tuarua. Kua whakahaerehia e mātou tēnei kawa whakamātautau me te tekau mā whā ngā kiritaki i roto i ngā tau e toru kua pahure ake nei, ā, tekau mā toru o rātou i neke ki tētahi whakatakotoranga whānui o te waka i roto i te iwa tekau rā. Ko te kiritaki kotahi kāore i tahuri ko te whakahaere i tētahi waka iti te whakamahinga i reira ko te rerekētanga utu waeine he nui ake i te penapena mō ia tana, ā, e whakaute ana mātou i tēnā hei whakatau tino tika. He pai ake ki a mātou te whiwhi kiritaki roa i te toa i tētahi ota kotahi kāore e taea e mātou te tiaki.

Te Utu-mō-ia-Tana: Me pēhea te whakaiti i te whakapaunga katoa o te keri kohatu mā te taha matatau kua whakapakeketia

Kāore i te maha ngā kōrero mō te hoko i roto i te rua keri e pā ana ki te utu kotahi o te taha; engari ko te utu mō ia tana o ngā rauemi i panaia, e piki haere ana te utu o te taha, te roa o te ora o te taha, te wā kore e taea te whakawhiti, me te utu tuarua o te tere o te kakahu o raro me ngā ringa pana. Kua kohia e mātou ngā raraunga o te mara mai i ngā rua keri e toru (he mahi tāpae karāhe i Fujian, he rua keri basalt i te Tai Tokerau o Vietnam, me te mahi kōhatu i te Rawhiti o Saudi Arabia) e kapi ana i te 24 marama o te mahi me ngā hāora mīhini rite. Ka tohaina e mātou te toharite puta noa i aua wāhi e toru i raro nei, i tātaitia ki te turanga o ngā taha waro-waenga papatahi (38 HRC) i whakatakotoria e mātou ki te 100 kia tika ai te whakataurite.

Hei whakatakoto i ēnei tāurangi ki ngā tau tino mō tētahi rua keri rahi-waenga noa, ka mahi mātou i roto i te pāngarau i te ara kotahi e mahia ana e mātou i roto i ā mātou awheawhe kiritaki: ko te D8T e pana ana i te 1,400 tana mō ia nekehanga i te tāurangi utu turanga o te 100 e rite ana ki te USD 0.18 mō ia tana e panaia ana i roto i te utu taha, pito, me te wā kore mahi. Nō reira, ko te pūnaha GET ōrite i te tāurangi 71 ka eke ki te USD 0.128 mō ia tana, ā, ko te mōkihi whakapakeke-tino-pai i te tāurangi 63 ka eke ki te USD 0.113 mō ia tana. I roto i te pana ā-tau 2.4 miriona tana, ka penapena te pūnaha ōrite i te USD 125,000 ia tau mō ia dozer, ā, ko te mōkihi tino-pai ka penapena i te USD 161,000 ia tau mō ia dozer. Ka tohaina e mātou ēnei tau tohutoro ki ia kaiwhakahaere tiaki e tono ana i tētahi whakatau utu, nā te mea kua mōhio mātou ka neke te kōrero mai i te "utu taha" ki te "uara pūnaha taha" ina tae mai te utu mō ia tana ki runga i te tēpu. Ka arotakehia ēnei tau e tā mātou tīma pūtea ki te taumaha ā-tau a te kiritaki, ā, ka tohua e mātou ngā take e ahua pai rawa atu ana te kereme penapena - he pai ake ki a mātou te ngaro o tētahi whakatau utu i te tuku i tētahi pūnaha kāore e tutuki i te take ōhanga. He pai ake tā mātou moe i taua ara.

Ko te take ōhanga mō te whakataurite i te pakeke o te taha me te pito te kitenga tino kaha mai i ā mātou raraunga mara, ā, mā mātou e ārahi ngā kōrero utu katoa ki tēnei. Mā te hoko i tētahi taha kua whakapakeketia anake, me te waiho i ngā pito ripper ki te pakeke taketake OEM i whakaora i ētahi pakaru o te papa pokepoke, engari ko te wā kore i whakaritea mai i te whati o te pito i te wā o te ripping pass i pana ake te utu katoa ki runga ake i te turanga. Ko te pūnaha ōrite te whirihoranga e taunakihia ana e mātou i te taunoa; ko te mōkihi tino whakapakeketia ko te whirihoranga e taunakihia ana e mātou mō ngā keri e neke atu ana i te 4,000 hāora ia tau i runga i te dozer kotahi. Kua whakamatauria hoki e mātou te mōkihi tino pai i runga i ngā keri iti e toru i raro iho i te 2,000 hāora ia tau, ā, kāore te utu pikinga i runga i te pūnaha ōrite e utu i roto i te pakanga taha tuatahi; nō reira ka arahina e mātou ngā kiritaki iti te whakamahinga ki te pūnaha ōrite hei taunoa whaitake. Ka tohaina e mātou tā mātou ture whānui: ki te mea kei raro iho i te 50 ōrau tō whakamahinga ā-tau mō ia mīhini, ko te pūnaha ōrite te tuanui tika, ā, kaua koe e akiakihia ki te mōkihi tino pai e tētahi kaiwhakarato e whai ana i te utu hoko toharite teitei ake. Ka kōrero mātou ki ngā kiritaki ahakoa ka utua e mātou te ota whakapai ake.

Te Tikanga Tirotiro me te Hurihanga e Whakaroa Ana i te Roa o te Ratonga o te Tapa Kua Whakapakeketia

Ahakoa te mata kua whakapakeketia pai rawa atu, ka ngoikore te mahi mēnā ka tāutahia ki muri, ka hē te hurihanga, ka hurihia rānei ki tōna ahunga pakaru, ā, kua ako mātou i tēnei mā roto i ā mātou ake kereme whakamana me ngā arotake a ngā kiritaki. Ka whakaratohia e mātou te kawa tirotiro e ono-taahiraa e whai ake nei mō ia kāri raraunga, ā, kua whakamahia e ā mātou miihini mara hei whakaora i te 12-18 ōrau o te roa o te ora mai i ngā mata kua whakapakeketia i roto i ngā keri i mua i whakaaro i ngā mata he mea maka noa iho. Kua waiho e mātou tēnei kawa hei whakaurunga paerewa i roto i ia tuku mai i te tau 2022.

1. Whakaūtia te tau wāhanga me te arongai mua i te whakairinga; me anga te taha piko o te taha ki te mea kua pakaru, kaua ki te mea kua tapahia. Kua kite mātou i tēnei kua hurihia i te iti rawa kotahi i roto i ia kiritaki e arotakehia ana e mātou, ā, e kore e taea te hē te tauira kakahu i roto i ngā haora e rima tekau.
2. Whakatōngia ngā pūtu tahaki te uara OEM (te tikanga 760-920 Nm mō te akomanga D7/D8), kātahi ka hurihia te taipana i muri i ngā haora 50 tuatahi o te mahi nā te mea ka tau te mata o ngā nohoanga. Kei a mātou ngā kaihangarau o te mara ā rātou ake kī taipana kua whakatikatikaina nā te mea i ako mātou ka neke haere ngā kī o te toa mā te 8-12 ōrau i roto i te tau kotahi.
3. Hurihia ngā taha mai i mua ki murii te 50 ōrau o te roa o te ora e tumanakohia ana, nā te mea ka puhoi ake te pakaru o te taha o muri i te taha o mua i te nuinga o ngā tauira pana. Ka tuhia e mātou te hurihanga ki te kāri raraunga kia mōhio ai te kapa e whai ake nei ko tēhea taha ka neke.
4. Tirohia mēnā he pakarui ia wā 100-hāora; ko te maramara whānui atu i te 8 mm, roa atu rānei i te 25 mm he mea whakakapi mō te aukati-mārō ahakoa te matotoru e toe ana. Ka kī atu mātou ki ngā kaiwhakahaere tiaki katoa e mahi tahi ana mātou ko te mata pakaru e whakamahia ana he mata whati kei te tatari kia puta mai ā muri ake nei.
5. Inehia te matotoru e toe anai te rohe pakaru me ngā calipers, kaua i te aromatawai ā-kanohi, nā te mea he koretake te pakaru o ngā taha kua whakapakeketia, ā, ka whakaitihia e te aromatawai ā-kanohi te ngaronga mā te 15-20 ōrau i roto i ā mātou arotake whakangungu.
6. Tuhia te tere o te kakahui roto i te rārangi mīhini kia taea ai te tono i te taha e whai ake nei i mua i te hinganga o te mea o nāianei; mā tēnei tikanga kotahi ka whakakorea te āhuatanga ohorere "kua pau ngā taha i te Rāhoroi" e tino utu nui ai ngā keri i te wā whakatā kore i whakaritea.
