I te wā e whiriwhiri ana i ngā mīhini hurihuri, he tokomaha te hunga e aro nui ana ki te kaha o te kawenga, engari ka warewarehia e rātou tētahi tawhā nui – ko te whānui o te mīhini hurihuri. Inaa, ko te whānui o te mīhini hurihuri e pā tika ana ki tōna kaha kawenga, te maeneene o te nekehanga, te pumau, me ngā āhuatanga e tika ana. Mā te whiriwhiri i te whānui tika ka māmā ake te nekehanga o ngā taputapu; mā te whiriwhiri i te mea hē ka pā ki te whai huatanga me te haumaru.
Ka tātarihia e tēnei tuhinga te pānga o te diameter o te mīhini whakarewa mai i ngā tirohanga o ngā whakatakotoranga noa me te whakamahinga mahi.
1. Te whakarōpūtanga noa o ngā whakaritenga diameter caster
Ko te rahi o ngā wira ka wehea mā te whānui o te wira, ko ngā waeine noa ko ngā mirimita (mm) me ngā inihi (inihi). I runga i te rahi o te whānui, ka taea te wehewehe i ngā wira ki ngā wāhanga e whai ake nei:
Ngā wira iti (25–75mm)
He iti te rahi me te ngāwari o te whakamahi, he pai mō ngā taputapu mama, mō ngā mahi rānei e nui ana te hiahia urungi, engari he iti noa iho tōna kaha ki te pikau kawenga.
Ngā wira rahi-waenga (100–150mm)
He pai mō ngā taputapu taumaha-waenga, ā, he whānuitia ngā rahi e kapi ana i te taumahatanga e taea ana te pikau.
Ngā wira mahi-taumaha (150–200mm)
He kaha tōna kaha ki te kawe, he pai mō ngā taputapu taumaha ake, he iti ake te kaha e hiahiatia ana ki te neke, ā, he pai ake te urutau ki ngā āhuatanga rerekē o te whenua.
Ngā wira mahi taumaha rawa atu (neke atu i te 200mm, ko ētahi tae atu ki te 350mm)
E whakamahia ana mō ngā āhuatanga mahi motuhake, mō ngā taputapu taumaha rawa rānei, e whakanui ana i te mahi kawe kawenga me te mahi whakawhiti, ā, he nui hoki ngā whakaritenga mō te wāhi.
2. Te pānga nui o te diameter o te mīhini ki te mahi
1). Te kaha o te kawe
I raro i te kaupapa o te hanganga me te rauemi ōrite, ko te rahi ake o te diameter o te wira hurihuri, ko te kaha ake o te kaha ki te kawe kawenga. Ka taea e ngā wira nui ake te tohatoha i te taumaha kia ōrite, ka whakaiti i te ahotea ā-rohe, ā, ka whakapiki ake i te rohe kawenga whānui.
2). Te nekenekehanga me te urutau ki ngā āhuatanga o te whenua
I ngā taiao kāore i te ōrite te whenua, he maha ngā āputa, he arai rānei, he nui ake te tūponotanga o ngā mīhini huri whānui ki te "hiki" i ngā arai, ki te hurihuri maeneene ake, me te whakaiti i te pānga me te kino ki te whenua.
3). Te pumau o te nekenekehanga
Ko ngā wira hurihuri he whānui ake te whānui, he pai ake te pumau i ngā wā taumaha, i ngā nekehanga tere rānei. Nā te mea he nui ake te kore e taea te huri i ngā wira nunui, ā, kāore e ngāwari te wiri nui nā ngā arai iti, ngā wiri rānei.
4). Te whakataurite i te taiao whakamahinga
He rerekē ngā whakaritenga mō te diameter o ngā wira i ia taiao whakamahinga. Hei tauira:
* Mō te nekehanga auau o ngā taputapu i roto i ngā whare putunga, i ngā wheketere rānei, he pai ngā wira waenga ki te rahi hei whakaiti i te ātete pana
* Mō te whenua o waho, mō te whenua taratara rānei, me nui ake te whānui hei whakapai ake i te ngāwari o te haereere
* Mēnā he iti te wāhi, ā, me māmā hoki ngā taputapu, he pai ake ngā wira iti te whānui
5). Te hanganga taputapu me te wāhi tāutanga
Ehara i te mea ko te whānui o ngā wira te mea pai ake, ko te rahi ake. Me whai whakaaro anō hoki ki te teitei o te taputapu tonu, te hoahoa hanganga, me te wāhi tāutanga e wātea ana. Tērā pea ka pā te whānui rawa ki te teitei whānui, ki te pumau rānei o te taputapu.
3. Me pēhea te whiriwhiri tika i te diameter o ngā wira?
Ko te whiriwhiri i te whānui o te mīhini whakarewa he tauwhitinga whānui i waenga i te kaha kawenga, ngā āhuatanga taiao, te pumau, me ngā āhuatanga ā-wāhi. I te wā e whiriwhiri ana i tētahi tauira, me whai whakaaro ki ngā take e whai ake nei hei whakatau:
He aha te taumaha katoa o te taputapu?
*He papatahi, he ōrite rānei te whenua e whakamahia ana?
*Me nekeneke haere tonu, me pana rānei i tawhiti?
He herenga kei te wāhi tāutanga?
Kia tutuki rā anō ēnei whakaritenga katoa ka taea ai e ngā kaihuri te mahi tino pai.
Whakamutunga
Ahakoa he tawhā noa iho te whānui o te wira, he mea nui tonu i roto i te whakamahinga mahi. Mā te whiriwhiri tika i te whānui o te wira, ehara i te mea ka pai ake te nekenekehanga engari ka roa ake hoki te roa o te mahi a te wira me ngā taputapu. Mā te mahi i tētahi atu taahiraa i te wāhanga whiriwhiri ka taea te karo i te raruraru o te whakakapinga me te tiaki pinepine i ngā wāhanga o muri mai.
Ki te hiahiatia, ka taea hoki e au te āwhina i a koe ki te whakarerekē ake i tēnei hei putanga "Ripanga Tohutoro Tere mō te Kōwhiringa Tauira", ki te wehewehe rānei kia maha ngā tuhinga i runga i ngā horopaki tono kawenga māmā/waenga/taumaha.
