E hiahia ana ngā mākete kōhatu kaweake ki ngā rahi poraka tika me te kounga ōrite.YT27 wiri toka hauKa āwhina i ngā papa kōhatu ki te whakaputa i ngā āhua poraka ōrite mā te pupuri i ngā ara keri tika i ngā hononga taiao.

Ka whakaitihia te para, ka whakaitihia ngā utu kawe, ā, ka whakapiki ake i te putanga katoa o ngā rua kohatu — he painga matua tēnei mō ngā kaihokohoko e pāngia ana e ngā wā tuku poto.

Mai i ngā whatiwhatinga koretake ki ngā poraka werohia tika

Mō ngā tau maha, i pāngia ngā rangatira o te rua kohatu i ngā mahi kōhatu o Valtina Ridge e te raruraru tonu. I te nuinga o te wā, i hiahiatia ā rātou kōhatu hina kounga teitei e ngā kaihanga i Tiamana me Kōrea ki te Tonga, engari he uaua te whakatutuki i ngā aho keri 3-mita te roa, he tika, he tika hoki, e hiahiatia ana mō te wehenga poraka ma. Ka "haere" mārire ngā keri paerewa i te ara kua whakaritea, inā koa i ngā uaua quartz pakeke. Nā tēnei i puta ai he whati huna o roto, he mata poraka koretake rānei, ā, ka akiakihia ngā kaimahi ki te whakapau i ētahi atu mahi ki te tapahi whakatikatika, ki te whakaheke rānei i ngā rauemi kounga teitei mō te whakamahinga o te whare nā te kore e tutuki i ngā whakaritenga kaweake. Ko te moumou wā me te kōhatu matua he mea whakaroa tonu i te hua.

Ko te whakaurunga o te pūnaha YT27 i aro ki tēnei ngoikoretanga matua. Ko tōna āhuatanga motuhake, ko te Gyro-Stable Pilot Bit Assembly, te mea nui. Kāore i rite ki ngā pūnaha tuku iho e taea ai e te mata te huri, ka whakamahia e tēnei huihuinga he hongere ārahi mō te kaha patu, kia mōhio ai ko te pūwāhi wero tuatahi te ara katoa o te raina keri. Mō ngā kaimahi o Valtina, i kitea te rerekētanga tonu ehara i te mea i runga i te ripanga tātai, engari i roto i te puranga para. Ko ngā "para whakapaipai koretake" - ngā puranga o ngā kohatu i mua he kohatu hoko - i heke iho i te 40% i roto i ngā marama tuatahi e rua o te mahi.
