Huihuinga o mua o te mīhini CAT-E345B/E349D/1156366/2487255/hanga me te kaiwhakarato wāhanga anga o te keri hanga taumaha

1. Tirohanga Whānui o te Huihuinga o te Idler o Mua

Tehuihuinga o mua o te mangereHe wāhanga nui tēnei i roto i te pūnaha raro o ngā keri Caterpillar E345 me E349. He tikanga ārahi me te whakapūmau i ngā ara, kia pai ai te mahi me te tika o te tūnga i te wā e keri ana. Ka mahi tahi te huihuinga mangere me te puna hoki me te kaiwhakatikatika ara waipēhi hei pupuri i te pūmautanga ara pai me te mimiti i ngā ru i te wā e mahi ana.

Ko ngā wāhanga matua o te pūnaha ko:

• Wira Whakamuri o Mua: Ko te wira ārahi matua e pupuri ana i te whakaōrite o te ara.
• Puna Whakamuri: Ka mimiti i ngā pānga me te whakaiti i te ahotea ki raro i te waka.
• Kaiwhakatika Ara Waipēhi: Ka taea te whakatikatika tika i te kukū o te ara.
• Ngā Peera Tautoko me ngā Hiri: Kia maeneene te hurihanga, kia kore ai e poke.

Ngā Whakatakotoranga Hangarau

I runga i ngā tauira Caterpillar rite (pērā i te 345C), ko te huihuinga o mua o te idler mō te E345/E349 he rite tonu ngā āhuatanga:

• Taumaha: Tata ki te 589 kg (1300 lb) mō te huihuinga katoa (tae atu ki te idler, te puna recoil, me te adjuster waipēhi).
• Rauemi: He mea hanga mai i te maitai kaha-teitei pērā i te 40Mn/45Mn, me te pakeke o te mata o te HRC 50-56 me te hohonutanga whakapakeke o te 5-8 mm hei ātete ki ngā taiao whakakoi.
• Te Whakataetae Pito Tuai: E kī ana ngā whakatakotoranga mai i ngā tauira rite he tawhiti tuai i waenga i te 0.26 mm (0.010 inihi) te iti rawa me te 1.26 mm (0.050 inihi) te mōrahi mō te mahi tika 2.
• Whakahinuhinu: Me whakamahi hinu SAE 30-CD (tata ki te 0.625 ± 0.30 rita) mō te whakahinuhinu ā-roto, me te hinu motuhake (pēnei i te kātere hinu 5P-0960) mō ngā mata o waho.

Ngā Tukanga Tāutanga

He mea nui te tāutanga tika mō te roa o te wā me te mahi. Anei ngā mahi matua e hangai ana ki ngā aratohu a Caterpillar:

1. Te Whakarite: Horoia pai ngā mata katoa o te mīhini huri hiko kia tangohia te paru me ngā mea para. Kia tino mohio kei pakaru te idler, ngā tautoko puna hurihuri, me ngā peera rango waipēhi.
2. Te Hiki me te Tūnga: Whakamahia ngā taputapu hiki e tika ana nā te mea he taumaha ngā taumaha:
   • Puna whakamuri: ~279 kg (615 pauna)
   • Kaiwhakatika ara waipēhi: ~52 kg (115 lb)
   • Huinga katoa: ~589 kg (1300 pauna)

Te Tiaki me te Whakamātautau

Mā te tiaki auau ka pono, ka roa ake hoki te ora o te ratonga:

• Whakamātautau Pēhanga: Me pupuri te huihuinga mangere i te pēhanga hau o te 245-265 kPa (36-38 psi) mō te iti rawa 30 hēkona ina whakamatautauria mā te putanga mono paipa. Mā tēnei ka tirohia te pono o ngā hiri o roto.
• Tirotiro Hiri: I te wā e huihui ana, kia tino ma, kia maroke, kia kaua e miro ngā hiri mata rapa. Me tapawhā ngā mowhiti hiri whakarewa, me te whakanoho tika. Whakahinuhinuhia ngā mowhiti-O ki te hinu whakahinuhinu kua whakaaetia (6V-4876).
• Whakahinuhinu: Whakamahia ngā hinu me ngā hinu kua tūtohutia anake. Mā te whakahinuhinu kore e tika ka pakaru wawe, ka pakaru rānei.
• Tirotiro Ātea: Aroturukihia te pureitanga pito tuaka i ia wā kia mau tonu ai i roto i ngā manawanui kua tohua.
