Ngā Whakatakotoranga Hangarau me ngā Tuhinga Hangarau mō te Roera Ara Keri Iti CAT 306

1. Whakarāpopototanga Whakahaere me te Tirohanga Whānui mō ngā Wāhanga

E whakaahua whānuitia ana e tēnei tuhinga te huihuinga roera ara (e mōhiotia ana ko te roera idler, te roera raro rānei), he wāhanga matua o te chassis o ngā keri waipēhi iti raupapa Caterpillar 305E, 306E, me te 307E. I hangaia mō ngā āhuatanga mahi uaua o ngā keri iti 1–6 tana, ka taea e tēnei huihuinga te tu atu i ngā kawenga pānga pūmau me te hihiri i raro i ngā āhuatanga rerekē, tae atu ki te hanganga, te whakaora ahuwhenua, me te hangarau ā-tāone. Ko te nama wāhanga matua 352-6217 i whakahuatia i roto i tēnei tuhinga ko te nama paerewa a te kaihanga taputapu taketake (OEM) mō tēnei huihuinga, e rite ana ki te huihuinga roera ara katoa me ngā wāhanga whakakapinga tika. Hei huarahi kē atu mō te hokohoko muri-mākete kounga teitei, ko tēnei huihuinga, i hangaia e te kaihanga wāhanga mīhini hanga ngaio, e piri pono ana ki ngā paerewa hangarau CAT OEM, e tutuki ana, e hipa ana rānei i ngā whakaritenga OEM i roto i te kōwhiringa rauemi, te hoahoa hanganga, me te mahi, e whakarato ana i tētahi otinga pono, ōhanga, me te roa mō te tiaki chassis keri iti. 2. Ngā Mahi Matua me te Mahi o te Pūnaha Ara

Ko te huihuinga roera raro he wāhanga matua o te pūnaha hikoi ara o te keri iti, e mahi ana i ngā mahi matua e toru e whai ake nei:

2.1 Te Whakapūmau Utaina me te Tohatoha Taumaha

Mā te tautoko tika i te taumaha katoa o te keri CAT 306 raupapa (tata ki te 5.7–7 tana), ka tohatoha ōrite te taumaha o te tinana o runga me te kawenga mahi ki te mekameka ara mā te anga roera, kātahi ka tohatoha atu ki te whenua. Mā te tohatoha maha-ira o ngā roera tautoko ka whakaitihia te pēhanga whenua, ka whakarite kia taea te haere o te taputapu ki runga i te whenua ngohengohe, me te ārai i te kino o te ara i puta mai i te kukū o te ahotea ā-rohe.

2.2 Te Arataki me te Whakahāngai i te Ara

He hanganga rua-rua kua oti te hanga ki ngā taha e rua o ngā roera, e tika ana te whakauru i te taha o roto o ngā hononga ara hei hanga i te here taha pono. Mā tēnei hoahoa ka ārai i te peka taha me te hekenga o ngā ara i te wā e huri ana, e piki ana, e mahi ana rānei i runga i te whenua taratara, e whakarite ana i te nekehanga maeneene o te ara i te anga anga me te whakapai ake i te pumau o te whakahaere mīhini whānui.

2.3 Te Whakahaere i te Hekenga o te Ara

Mā te mahi tahi me ngā wira ārahi me ngā whakapūmau, he mea nui te pupuri i te taumahatanga me te hekenga tika i te mekameka ara o runga (e whakahaeretia ana i te 1–2% o te roa o te iri o te ara) hei arotau i te pānga hononga i waenga i ngā wira taraiwa me ngā ara, hei whakaiti i te wiri mahi, me te whakaiti i ngā ngaronga tuku hiko. Ka whakaroa hoki i te roa o te mahi a ngā ara me ētahi atu pūnaha wira.
