Ko te anga o raro me te taputapu hurihuriKo tētahi o ngā hoahoa matua mō ngā keri hei whakatutuki i ngā mahi whai hua me te ngāwari. Ka whakakotahi pai i te taputapu mahi o runga (puku, rākau, peere, me ētahi atu) me te tikanga haere o raro (ara, potae rānei) ā, ka taea te huri 360° mā te pūnaha whīra me te pūnaha taraiwa, ā, ka nui ake te whānuitanga o te mahi. Koinei te tātari taipitopito o ōna tono me ōna painga:
I. Te Hanganga o te raro hurihuri
1. Whēra Hurihuri
- He peera pōro nui, he peera roera rānei e hono ana i te anga o runga (wāhanga hurihuri) ki te anga o raro (chassis), e mau ana i ngā kaha toki, ngā kaha radial, me ngā kaha hurihuri.
- Ngā momo noa: ngā peera pōro whakapā-whā-ira kotahi-rārangi (mama), ngā peera roera whakawhiti (taumaha).
2. Pūnaha Puku Hurihuri
- Mōta waipēhi: ka peia te taputapu whīra hurihuri mā roto i te whakaiti hei whakatutuki i te hurihuri maeneene (otinga matua).
- Mōta hiko: e whakamahia ana i roto i ngā keri hiko, e whakaiti ana i ngā mate waipēhi me te whakarato i te urupare tere ake.
3. Hoahoa o raro o te waka kua whakapakaritia
- He anga rino kua whakapakaritia hei whakarite i te pakari me te pumau o te takahuri i te wā e whiri ana.
- Ko te raro o te waka momo ara e hiahiatia ana he whānui ake te ine ara, ko te anga ia o te potae me whakauru he ama waipēhi hei taurite i te nekehanga hurihuri.
II. Ngā Whakapainga Matua ki te Mahi a te Keri
1. Ngāwari o te Whakahaere
- Mahi Kore Ārai 360°: Kāore he take ki te neke i te anga kia kapi i ngā wāhi katoa e karapoti ana, he pai mō ngā wāhi whaiti (pēnei i te hanganga tāone, te keri paipa).
- Te Tūnga Tika: Mā te whakahaere ōrite o te tere o te werohanga ka taea te tūnga o te peere ki te taumata mirimita (pēnei i te whakaotinga o te poka turanga).
2. Te Arotau i te Whai Hua o te Mahi
- Te Whakaiti i te Auautanga Nekehanga: Me whakarerekē pinepine ngā tūranga o ngā keri ringa-pūmau tuku iho, engari ka taea e te anga hurihuri o raro te huri i ngā mata mahi mā te hurihuri, ka penapena wā.
- Ngā Mahi Whakakotahitanga: Mā te whakahaere i te hononga pūmau me te pūmau (pēnei i ngā mahi "swing") ka pai ake te whakahaere huringa.
3. Te Pūmautanga me te Haumarutanga
- Te Pokapū Whakahaere Taumaha: Ka tohatohahia ngā kawenga hihiri i te wā e nekehia ana mā roto i te raro o te waka, ā, ka āraihia e te hoahoa taumaha taurite te huripokitanga (pērā i ngā taumaha taurite e mau ana ki muri i runga i ngā keri keri).
- Hoahoa Ārai-wiri: Ka āraia te ngoikore i te wā e pēhi ana i te aukati e te raro, ka whakaiti i te pānga hanganga.
4. Whakawhanuitanga Maha-mahi
- Ngā Atanga Huri-Tere: Mā te anga slewing ka taea te whakakapi tere i ngā āpitihanga rerekē (pēnei i ngā hama waipēhi, ngā hopu, me ētahi atu), ka urutau ki ngā āhuatanga rerekē.
- Te Whakaurunga o ngā Pūrere Āwhina: Pēnei i ngā aho waipēhi e hurihuri ana, ngā āpitihanga tautoko e hiahia ana kia hurihuri tonu (pēnei i ngā ūkui).
III. Ngā horopaki tono noa
1. Ngā Pae Hanga
- Te whakaoti i ngā mahi maha pēnei i te keri, te uta, me te whakataurite i roto i te wāhi iti, me te karo i te nekehanga pinepine o te anga me ngā tukinga ki ngā arai.
2. Te keri
- Ngā keri nui-tāuna me te anga whakakoi kaha hei tu atu i te keri taumaha me te hurihuri tonu mō te wā roa.
3. Te Whakaora ā-Ohotata
- He tere te tapahi hei whakatika i te ahunga mahi, me te whakamahi tahi me ngā hopu, me ngā kutikuti rānei hei tango i ngā paru.
4. Ahuwhenua me te Ngāherehere
- Mā te anga hurihuri ka māmā ake te hopu me te whakarārangi i te rakau, te keri hōhonu rānei i ngā rua rākau.
IV. Ngā Auahatanga Whakawhanake Hangarau
1. Mana Hurihuri Maamaa
- Te aroturuki i te koki hurihuri me te tere mā te IMU (Inertial Measurement Unit), ka aukati aunoa i ngā mahi morearea (pēnei i te sling i runga i ngā pari).
2. Pūnaha Hurihuri Mana Ranu
- Ka whakahokia mai e ngā motuka hiko hurihuri te kaha aukati, ka whakaitihia te whakapaunga wahie (pērā i te keri ranu Komatsu HB365).
3. Taurite o te Mama me te Pakari
- Te whakamahi i te maitai kaha-teitei, i ngā rauemi hiato rānei hei whakaiti i te taumaha o raro i te waka, me te whakapai ake i te hiri o te peera hurihuri (ātete puehu, ātete wai).
V. Ngā Wāhi Tiaki
- Te whakahinuhinu auau i te peera hurihuri: Ka ārai i te pakaru o te ara reihi e puta ai te haruru, te rūrū rānei o raro o te waka.
- Tirohia te utaina o mua o te pūtu: Ka pā mai pea ngā mōrearea hanganga mēnā ka wetekina ngā pūtu e hono ana i te whāriki whiri me te anga.
- Aroturuki i te ma o te hinu waipēhi: Ka taea e te poke te arahi ki te kino o te motuka hurihuri me te pā ki te mahi a te taraiwa o raro.
Whakarāpopototanga
He hoahoa motuhake te anga o raro o te waka me te tikanga hurihuri e wehewehe ana i ngā kerikeri i ētahi atu mīhini hanga. Mā te tikanga o te "papa raro pumau me te tinana o runga hurihuri", ka tutuki he aratau mahi whai hua, ngāwari me te haumaru. I te heke mai, me te urunga mai o te hiko me ngā hangarau atamai, ka whanake tonu te papa raro hurihuri ki te tiaki pūngao, te tika me te roa, ka noho hei hononga matua i roto i te whakapai ake hangarau o ngā kerikeri.
