Takirere Pōro CS e Mau ana ki te Trunnion Āwhina Hau mō te Tank Hinu i Haina wheketere
He aha te takirere pōro trunnion hau?
Tetakirere pōrohe momo takirere huri-hauwhā e whakamahi ana i tētahi pōro tuwhera, he kōhao, he pōro pumau/tautoko hei whakahaere i te rere o roto.
Hetakirere pōro trunnion hauko te tikanga he herenga te pōro e ngā peera, ā, ka taea anake te huri, ko te nuinga o te kawenga waipēhi e tautokona ana e ngā herenga Pūnaha, ka hua ake he iti te pēhanga peera, ā, kāore he ngenge o te pou.
Ka panaia te nohoanga o runga e te pēhanga o te paipa ki te pōro tūmau, kia panaia ai te nohoanga o runga e te pēhanga raina ki runga i te pōro, kia hiritia ai. Ka mimitihia e te punga ā-ringa o te pōro te pana mai i te pēhanga raina, ka ārai i te waku nui i waenga i te pōro me ngā nohoanga, nō reira ahakoa te pēhanga mahi kua whakatauria katoatia, ka noho tonu te taipana whakahaere he iti. He tino painga tēnei ina whakamahia te takirere pōro nā te mea ka whakaitihia te rahi o te kaiwhakaoho, ā, nō reira ka whakaitihia te utu whānui o te mōkihi whakahohenga takirere.
Ko ngā painga o te hoahoa pōro trunnion ko te iti o te taipana whakahaere, te ngāwari o te whakahaere, te iti o te pakaru o te nohoanga (mā te wehewehe o te kakau/pōro ka ārai i te uta taha me te pakaru o ngā nohoanga o raro, ka whakapai ake i te mahi me te roa o te ratonga), te mahi hiri pai rawa atu i te pēhanga teitei me te pēhanga iti (ka whakamahia he pūnaha puna motuhake me te pēhanga raina o runga hei hiri ki te pōro tūmau mō ngā tono pēhanga iti me te pēhanga teitei).
