Mena kei te ruarua tonu koe mēnā ko ngā takirere kēti maitai hanga, ko ngā takirere kēti maitai whakarewa rānei (WCB), tirohia te wheketere takirere zfa kia kitea ai ngā rerekētanga nui i waenganui i a rāua.

1. He rerekē ngā tikanga tukatuka e rua o te hanga me te whakarewa.

Te Maka: Ka whakamahanahia te konganuku, ka rewahia, kātahi ka ringihia ki roto i te pokepoke onepu. Kia whakamatao, ka totoka hei mea. Ka ngāwari te hanga i ngā kōhao hau i waenganui o te hua.
Te Hanga: Ko te tikanga matua ko te patu i ngā pāmahana tiketike hei hanga i te konganuku kia rite ki tētahi āhua me te rahi o tētahi mea mahi i roto i te āhua kirihou, me te whakarerekē i ōna āhuatanga ā-tinana.

2. Ngā rerekētanga o te mahi i waenga i ngā takirere kuaha hanga meNgā takirere keti WCB

I te wā e hanga ana, ka rerekē te āhua o te konganuku, ka whakamahia ai ngā konganuku ki te hanga i ngā wāhanga nui. He whakaritenga kei roto i te whakarewanga mō ngā rauemi hei tukatuka. Ko te tikanga, he pai ake ngā āhuatanga whakarewa o te rino maka, te konumohe, me ētahi atu. Kāore i te maha ngā painga o te hanga i ngā wāhanga he uaua, engari ka taea te hanga i ngā wāhanga he uaua te āhua, nō reira he maha ngā whakamahinga i roto i te hanga i ngā wāhanga tautoko kāore e hiahiatia he āhuatanga miihini teitei.

2.1 Pēhanga

Nā te rerekētanga o ngā āhuatanga rauemi, ka taea e ngā takirere maitai hanga te tu atu i ngā kaha pānga nui, ā, he teitei ake ō rātou kirihou, pakari me ētahi atu āhuatanga miihini i ērā oNgā takirere WCBNō reira, ka taea te whakamahi i roto i ngā āhuatanga mahi pēhanga teitei ake. Ko ngā taumata pēhanga e whakamahia whānuitia ana mō ngā takirere maitai hanga ko: PN100; PN160; PN250; PN320; PN400, 1000LB~4500LB. Ko ngā pēhanga ingoa e whakamahia whānuitia ana mō ngā takirere WCB ko: PN16, PN25, PN40, 150LB~800LB.

2.2 Diameter Ingoa

Nā te mea he nui ngā whakaritenga mō ngā pokepokea me ngā taputapu mō te tukanga hanga, ko te diameter o ngā takirere hanga he iti iho i te DN50.

2.3 Te āheinga ārai-tātari

E whakatauhia ana e te tukanga tonu, ka puta he pūngao i te wā e tukatukahia ana te whakarewanga. Nō reira, ki te whakaritea ki te tukanga hanga, kāore te kaha o ngā takirere whakarewa e ārai ana i te turuturu i te pai ki ērā o ngā takirere hanga.
Nō reira, i roto i ētahi ahumahi he nui ngā whakaritenga mō te ārai turuturu, pērā i te hau, te hau māori, te hinu, te matū me ētahi atu ahumahi, kua whānuitia te whakamahinga o ngā takirere maitai hanga.

2.4 Āhua

He māmā noa te wehewehe i te āhua o ngā takirere WCB me ngā takirere maitai hanga. I te nuinga o te wā, he hiriwa te āhua o ngā takirere WCB, ko ngā takirere maitai hanga ia he mangu te āhua.

3. Ngā rerekētanga o ngā mara tono

Ko te kōwhiringa motuhake o ngā takirere WCB me ngā takirere maitai hangai ka whakawhirinaki ki te taiao mahi. Kāore e taea te whakawhanui i ngā mara e whakamahi ana i ngā takirere maitai hangai, me ngā mara e whakamahi ana i ngā takirere WCB. Me hangai te kōwhiringa ki te taiao mahi motuhake. I te nuinga o te wā, kāore ngā takirere WCB e ātete ki te waikawa me te kawakore, ā, ka taea anake te whakamahi i runga i ngā paipa noa, engari ka taea e ngā takirere maitai hangai te tu atu ki te pēhanga teitei, ā, ka taea te whakamahi i roto i ētahi wheketere he pāmahana teitei, pērā i ngā tipu hiko me ngā tipu matū. Akomanga takirere.

4. Utu

I te nuinga o te wā, he nui ake te utu o ngā takirere maitai hanga i tērā o ngā takirere WCB.
