Ngā kōwhiri rīwhi hau , ka whakahaeretia e te hau pakaru, e whakaatu ana i ngā anamanui matua ki ētahi āhuatanga motuhake, ina ko ngā tauira ringa me ngā tauira takotoranga e pai ake ana.
Ka mahi mā te hau pakaru, kāore ēnei karuwha e hāngai anuanu i te wā o te mahi, nō reira he tino pai mō ngā puna kiko, ngā taiao kikokiko, me ngā karipari maroke. He tino teitei ake te tau ārai mate i te taputapu hiko.
Ko ngā tauira ringa (pērā i te Y19A me te YO18) he māmā te hainatanga (heoi anō i raro i te 25kg), māma ake te kawekawe me te whakahaere, e tika ana mō te ruarua i ngā wāwahi penei i ngā wāwahi āwhina, ngā wāwahi takotoranga, me ngā wāwahi tuarua. Ko ngā tauira takotoranga (pērā i te YT27 me te YT28) ka whakamahi i tētahi waewae hau hei tautoko me te taraiwa, ka taea te ruarua i ngā wāwahi parerā, aronga ki te taha, ki runga rānei ki ngā wāwahi pākihi tae atu ki te 5 mita te roa, nō reira he mea pai mō te whanaketanga i ngā karuwha kōhanga.
Ka pakari ēnei ruarua ki ngā tikanga pīroiroi pērā i te pouri me te puehu. Ka taea hoki te ruarua i te wai kia mōhiotia ai te puehu, ka pai ake ngā tikanga mahi.
Ahakoa he iti ake te rereketanga o te hiko i ngā taputapu hiko, ko ngā ruarua hau he iti noa te utu tuatahi, māma te tiaki, me te tino whakapono. E tuku ana i ngā painga tūmatanui moni mō ngā kōhanga iti, hekepeke rānei, i ngā kaupapa rānei e herea ana e te tahumaero.
E pēnei ana te māmā e 6kg (hei tauira, te tauira Y6), ko ēnei pūpahi he mea tino maru ka taea te whakamahi mō ngā wāhi iti (Φ19-42mm) iti, te whakauru i ngā karu kaukau, te tautoko i ngā rārangi, me ētahi atu mahi āwhina, ina nui ake ngā wāhi iti.
He nui te taumaha o te 20-30kg (hei tauira, te tauira YT27 e 27kg ana), ko ēnei pūpahi ka tuku uara pānga e 75.5 joules nekehanga ki te noa rātā ≥36.9Hz. E taea ai te pūpahi i ngā wāhi pāmu 34-45mm te diamita i runga i te paraumu pakari ki te paraumu hoki (f=8-18), hei taputapu matua mō te whanaketanga ruwhenua.
Ko ngā karuwha pūpahi, īngoa noa rānei ko ngā tauira ringaringa me te momo waewae, e manawa tū ana hei kōwhiringa nui mō ngā whakahaerenga hauora ki te whenua, nā te haumaru, te maruaroa o te mahi, te āhua o te taiao, me te uaua o te utu. Kei te kōwhiri pai, ā, he kōwhiringa tautoko mō ngā pounamu iti, he rahi rānei, ngā mahi e hiahiatia ana te haumaru, ngā mahi tāwhai, me ngā kaupapa e noho mōhio ana.
