Te Pakari o te Taumata Maina: Huihuinga Wira Rererangi Hitachi EX1800 / EX1900

1. Kupu Whakataki: Te Tuarā o te Kerihanga Akomanga-Ultimate

I roto i te ao o te keri nui, te keri kōhatu, me te hanganga ā-iwi taumaha, ko te raupapa Hitachi EX1800 me te EX1900 te tihi o te mahi keri waipēhi. Me te taumaha whakahaere neke atu i te 180 tāne me te kaha o te peere tae atu ki te 15 mita pūtoru, ka mahi ēnei mīhini i raro i ngā āhuatanga mutunga kore—ngā kawenga pānga nui, ngā rauemi whakakoi, me ngā huringa nekehanga tonu.

Ko te Huinga Wira Pīrere Ara (e mōhiotia ana ko te huinga pīrere mekameka ara) te wāhanga matua o te pūnaha taraiwa e huri ana i te mana waipēhi hei kukume. Mō ngā mahi keri i te whitiki parahi o Chile, ngā maina konukawata o Awherika ki te Tonga, ngā mara rino rānei o Rūhia, ko te pono o tēnei huihuinga ka whakatau tika i ngā whāinga whakaputa me te utu mō ia tana.

Kei roto i tēnei tuhinga he tātaritanga hangarau hōhonu o te huihuinga sprocket kounga-OEM kua tautuhia mā ngā tau wāhanga.1028990,4451622, me4637264, i hangaia i raro i ngā tikanga pakari oAra CQC—he tohungatangawheketere pūtakemekaihangao ngā wāhanga o raro o te EXC mahi taumaha.

2. Ngā Whakatakotoranga Hangarau me te Whakawhitiwhiti

2.1 Te Tāutuhi Wāhanga

Ko ngā tau wāhanga e toru e rite ana ki ngā momo rerekētanga o te huihuinga sprocket e whakamahia ana puta noa i ngā papaaho Hitachi EX1800 me EX1900:

• 1028990: E pā ana ki te huihuinga wira porotiti katoa (pū + mowhiti) mō ngā whirihoranga puku whakamutunga motuhake.
• 4451622: E honoa whānuitia ana ki te mowhiti porotiti wehewehe, ki te huihuinga rānei mō ngā waeine EX1900 tauira hou.
• 4637264: He maha ngā wā e tohu ana i te kete wāhanga pītiti, i te mowhiti kakahu pūmau rānei, e āhei ai te whakakapinga mara me te kore e tango i te motuka puku whakamutunga.

Kua hangaia ēnei huihuinga kia hono atu ki te waeine whakaiti haere Hitachi (he maha ngā wā he atanga whakapiri kua whakapikohia, kua whakapurua rānei) ā, kua hangaia mō ngā mekameka ara he 317 mm, 350 mm rānei te piko, i runga i te whirihoranga o raro o te waka.

2.2 Ngā Āhuatanga Hanga Taumaha

He rerekē te porotiti EX1800/EX1900 i ngā wāhanga keri rahi-waenga, ā, kua hangaia kia tū atu ki:
