Ko te whiriwhiri i te Mīhini Hau Shenli ko te mahi tahi me tētahi waitohu kua roa e whakamahi ana i ngā tau 15 neke atu o te tohungatanga ahumahi. Ka whakatairangahia e mātou te pakari o ia wāhanga—ka whakamahia e tā mātou YT28 ngā rauemi ātete-mau mō ngā wāhanga matua, ka roa ake te roa o te ratonga mā te 30% ki te whakataurite ki ngā momo rerekē. Ka arotau tonu tā mātou tīma R&D o roto i ngā hoahoa, pērā i te taupoki whakangāwari whakauru e whakapai ake ana i te whakamarie o te wāhi mahi, ā, ka tukuna e mātou te tautoko whai muri i te hoko, tae atu ki te whakangungu tiaki i te papaanga me te urunga tere ki ngā wāhanga e manawapa ana. Kāore i rite ki ngā kaiwhakarato e whakaiti ana i te kounga, ka piri mātou ki ngā paerewa whakaputa tino pakari, me te whakarite kia paahitia e ia YT28 te 12 tirotiro kounga i mua i te tukunga.

Ka taea te ine i ngā hua pai o te YT28: e ai ki ngā maina he pikinga 40% te roa o te keri i ia rā. Hei tauira, i whakapiki ake tētahi maina waro i Shanxi i te ahunga whakamua o te kauhanga ia marama mai i te 80m ki te 112m i muri i te whakamahi i ā mātou YT28. Nā te hoahoa taurite o te keri ka whakaitihia te wā whakangungu kaiwhakahaere mā te 50%—ka taea e ngā kaimahi hou te whakahaere i ngā mahi taketake i roto i ngā rā e 3, kaua ki te 6 noa. Ka heke hoki ngā utu wahie mā te 15% nā te mea kua pai ake te whakamahinga o te hau (≤75L/s), he penapena nui mō ngā mahi keri nui.

Ehara i te mea tere, engari he utu hoki ngā painga. Nā te hoahoa mama (28kg) o te YT28 ka whakaiti i te kaha whakahaere, ka whakaiti i ngā whara e pā ana ki te mahi mā te 60%. Mā tōna hototahi ki ngā waewae hau FT160BD/BC me ngā papa taraiwa ka taea te keri whakapae, te keri piko, te keri rānei i runga ake. Nā te hanganga māmā, he māmā noa te tiaki—ka taea te whakatau i te nuinga o ngā take i te papaanga mā ngā taputapu taketake, ka tapahia te wā tiaki mā te 40%. Mō ngā maina me ngā tīma hanga, ka puta ēnei painga ki ngā kaupapa i te wā tika, ngā utu whakahaere iti iho, me ngā wāhi mahi haumaru ake. "I whakarerekē te YT28 i tā mātou whakangungu me te whakahaere," te kī a tētahi kaiwhakahaere maina. "He pono, he ngāwari ki te whakamahi, ā, ko ngā hua pai ake e kōrero ana mō rātou anō."

Mō ngā pātai tonu mō te YT28, ngā otinga keri toka ritenga rānei, whakapā atu ki te tīma hokohoko a Shenli Pneumatic Machinery mā te īmēra, mā te waea rānei. Ka tukuna e mātou te ao katoa, ka kawea mai ngā taputapu ngaio ki ngā kaupapa o ngā rahi katoa.
