Ko te ringa karetao āwhina-mana he taputapu miihini aunoa kua whakamahia whānuitia i roto i te ao karetao. Ka kitea i roto i te hanga ahumahi, te rongoā, ngā ratonga whakangahau, te ope taua, te hanga haurua-ira, me te tūhuratanga ātea. Ahakoa he rerekē ngā āhua, he āhuatanga ōrite katoa, arā, ka taea e rātou te tango tohutohu me te mahi i tētahi wāhi i roto i te wāhi toru-ahu (rua-ahu rānei). Nō reira, he aha ngā whakaritenga hoahoa mō tētahi ringa karetao āwhina-mana e hiahiatia ana? Kei raro nei, ka whakaatu te ētita ki a koe:
1、Me nui te kaha o te ringa karetao āwhina-mana ki te kawe kawenga, kia pakari, kia māmā hoki.
Ko te pakari o te ringa karetao āwhina-mana ka pā tika ki tōna pumau, tere, me te tika o te tūnga ina hopukina te mea mahi. Mēnā he ngoikore te pakari, ka puta he piko rerekētanga i te papa poutū me te takahuri rerekētanga taha i te papa whakapae o te ringa karetao āwhina-mana. Ka wiri te ringa karetao āwhina-mana, ka mau rānei te mea mahi, ā, kāore e taea te mahi i te wā e neke ana. Nā tēnei take, ko te tikanga ka whakamahia e te ringa ngā tokotoko arataki pakari hei whakanui ake i te pakari o te ringa, ā, ko te pakari o ia tautoko me ia hononga me whai whakaritenga anō hoki kia taea ai e ia te tu atu i te kaha taraiwa e hiahiatia ana.
2、Me tika te tere o te nekehanga o te ringa karetao āwhina-mana, ā, me iti te inertia.
Ko te tere o te nekehanga o te ringa karetao ka whakatauhia i runga i te auau whakaputa o te hua, engari kāore e tika ana kia whaia noatia te tere teitei. Ka tīmata te ringa karetao āwhina-mana ina tae ki te tere nekehanga noa mai i te āhua tūmau, ā, ka mutu ina mutu i te tere noa. Ko te tukanga tere rerekē he pihi āhuatanga tere. He tino māmā te taumaha o te ringa karetao āwhina, ā, he maeneene te tīmatanga me te mutu.
3、Me ngāwari te mahi a te ringa karetao āwhina.
Me kiato, kia pūmau hoki te hanganga o te ringa karetao āwhina mana, kia māmā ai, kia ngāwari ai hoki te nekehanga o te ringa karetao āwhina mana. Mā te tāpiri i ngā peera hurihuri, te whakamahi rānei i ngā kaiārahi pōro ki te pūma ka taea hoki te neke tere me te maeneene o te pūma. Hei tāpiri, mō ngā kaiwhakahaere cantilever, me whai whakaaro hoki ki te whakaritenga o ngā wāhanga i runga i te ringa, arā, te tatau i te taipana taurite o te taumaha o ngā wāhanga neke i runga i te hurihanga, te hiki, me ngā pokapū tautoko. Kāore te taipana taurite kore e pai ki te āwhina i te nekehanga o te ringa karetao. Ka taea e te taipana taurite kore nui te wiri o te ringa karetao āwhina mana, ka totohu i te wā e hiki ana, ā, ka pā hoki ki te ngāwari o te nekehanga. I ngā wā tino kino, ka mau pea te ringa karetao āwhina me te pou. Nō reira, i te wā e hoahoa ana i te ringa karetao āwhina mana, ngana kia haere te pokapū o te taumaha o te ringa mā roto i te pokapū o te hurihanga, kia tata rānei ki te pokapū o te hurihanga kia taea ai te whakaiti i te taipana piko. Mō te ringa karetao e mahi tahi ana me ngā ringa e rua, me rite te whakatakotoranga o ngā ringa ki te pokapū kia tutuki ai te taurite.
4、Me ngāwari te mahi a te ringa karetao āwhina.
Me kiato, kia pūmau hoki te hanganga o te ringa karetao āwhina mana, kia māmā ai, kia ngāwari ai hoki te nekehanga o te ringa karetao āwhina mana. Mā te tāpiri i ngā peera hurihuri, te whakamahi rānei i ngā kaiārahi pōro ki te pūma ka taea hoki te neke tere me te maeneene o te pūma. Hei tāpiri, mō ngā kaiwhakahaere cantilever, me whai whakaaro hoki ki te whakaritenga o ngā wāhanga i runga i te ringa, arā, te tatau i te taipana taurite o te taumaha o ngā wāhanga neke i runga i te hurihanga, te hiki, me ngā pokapū tautoko. Kāore te taipana taurite kore e pai ki te āwhina i te nekehanga o te ringa karetao. Ka taea e te taipana taurite kore nui te wiri o te ringa karetao āwhina mana, ka totohu i te wā e hiki ana, ā, ka pā hoki ki te ngāwari o te nekehanga. I ngā wā tino kino, ka mau pea te ringa karetao āwhina me te pou. Nō reira, i te wā e hoahoa ana i te ringa karetao āwhina mana, ngana kia haere te pokapū o te taumaha o te ringa mā roto i te pokapū o te hurihanga, kia tata rānei ki te pokapū o te hurihanga kia taea ai te whakaiti i te taipana piko. Mō te ringa karetao e mahi tahi ana me ngā ringa e rua, me rite te whakatakotoranga o ngā ringa ki te pokapū kia tutuki ai te taurite.
