I roto i ngā rāngai whakahaere me te kawe waka, ehara te pupuri i ngā utanga i te mahi tukanga noa iho; engari ko te arai nui i waenga i te tuku haumaru me te rahunga nui. Ahakoa he rite tonu ki tengā mekameka hiki,ngā mekameka here me ngā mekameka here(e kiia katoatia ana ko ngā mekameka kawe) he mahi motuhake, he mahi nui hoki. He mea hanga motuhake ēnei hei pupuri i ngā kawenga taumaha i te wā e kawe ana, ehara i te mea hei hiki i runga ake.
E ai ki te kōrero i te mara, e mahi ana ēnei mekameka i te taha ongā mekameka hikiMō ngā hua o te rahunga—ko ngā tūponotanga ko te haumaru o te tangata me te kounga o ngā utanga he nui te utu. Ka taea e te aituā i puta mai i te whati o te mekameka te arahi ki te whara kino o te tangata, te pakaru o te waka, me te ngaronga o ngā utanga katoa. Nō reira, ko te kounga o te mahi whakarewa me te tika o te maimoatanga wera te mea nui. Heoi, kāore e ranea ngā taputapu anake; ko te tikanga tono, e arahina ana e ngā mātāpono hangarau me te wheako o te mara, he mahi nui anō hoki.
I SCIC (www.scic-chain.com), ka tukuna e mātoumekameka here me te herehe mea hanga mai i te maitai koranu pakari. Ka tirotirohia me te whakamatautauria ia wāhanga kia tino mohio ai ka tukuna e mātou ehara i te mea he hua anake, engari he taurangi haumaru hoki. Kei roto i tēnei aratohu ngā tawhā matua, ngā tikanga whakahaere i te papaanga, ngā whakatūpato nui, me ngā paearu whakakapinga e tika ana mō te whakamahinga haumaru me te whai hua o ngā mekameka kawe.
1. Ngā Tawhā Hangarau Matua
Ko te mārama ki ngā whakaritenga hangarau o te mekameka te taahiraa tuatahi ki te whakamahinga haumaru. Me titiro ngā kaiwhakahaere me ngā kaihoko ki tua atu i te rahi ā-tinana o te mekameka, me te tātari i ngā tohu raraunga matua e whai ake nei, me mārama te tohu ki te mekameka, ki tōna tohu rānei.
a) Te Herenga Kawenga Mahi (WLL) vs. Te Kaha Pakaru
- Tepe Utaina Mahi (WLL): Koinei te kaha mōrahi i roto i te daN (dekaNewton) me ngā kirokaramu rānei ka taea e te mekameka hou te pupuri i roto i te kukume tika i te wā mahi noa. Koinei te rohe "haumaru". Mō ngā tono here, ka kiia tēnei ko te Kaha Here (LC).
- Te Kaha Pakaru (BF): Koinei te kaha iti rawa ka pakaru te mekameka i te wā o te whakamātautau whakangaro. He nui ake i te WLL. Ka whakamahia he tauwehenga haumaru paerewa (ko te tikanga he 4:1 mō ngā mekameka kawe), ko te tikanga he whā ngā wā kaha ake te mekameka i tōna WLL.
b) Te Tau me te Rauemi
He mea hanga ngā mekameka kawe hou ki te maitai koranu, ka tukatukahia ki te wera hei whakatutuki i ngā āhuatanga miihini motuhake.
-Tau 8 (hei tauira, Tau 80, Tau 100 rānei)Koinei te paerewa ahumahi mō te herenga mahi-teitei. Ko te tau (80, 100 rānei) e pā ana ki te taumata o te karaehe, e whakatau ana i te kaha kume. AMekameka Tau 100he nui ake te WLL mō te diameter ōrite ki te whakataurite kiTau 80, e māmā ake ai ngā mekameka, e māmā ake ai hoki te whakahaere me te kore e whakaiti i te kaha.
- Te Hanganga o ngā Rauemi: Me pakari, me ōrite hoki te maitai koranu kia tu atu ai i ngā ahotea hihiri o te kawe, me te kore e puta he whati moroiti.
c) Ngā Ahu me te Taurite
- Rahi Ingoa (Diameter): Ko te matotoru o te waea maitai i whakamahia hei hanga i ngā hononga. He hononga tika tēnei ki te WLL.
- Ngā Ahu ā-Roto: Me rawaka te roa me te whānui o roto i te hononga kia taea ai e ngā wāhanga hono (pēnei i ngā matau me ngā here) te noho tika me te kore e herea.
d) Ngā Wāhanga Pūnaha
Ehara i te mea ko ngā hononga mekameka anake te pūnaha mekameka here. Ko te ngoikore rawa o te pūnaha te mea e whakatau ana i te kaha katoa.
- Ngā Hononga Pito: Me rite te WLL o ngā matau (hei tauira, ngā matau hopu, ngā matau maikuku) me ngā mekameka ki te mekameka.
- Ngā Āmiomio (Rātiti, Rīwai rānei): Ka whakamahia ēnei hei whakamahi i te kaha āmiomio e tika ana ki te mekameka hei whakau i te kawenga.
2. Te Mahi i te Pae: Te Whakapūmau i te Utaina
Me whai huarahi pūnaha te whakahaere tika. Ka pāngia ngā mekameka kawe e ngā kaha "āhua-pūmau" (te whakatere, te aukati, te kokonga) me ngā kaha hihiri (te wiri). Ko te whāinga o te whakahaere i te papaanga he ārai i ēnei kaha.
a) Arotakenga i mua i te Whakamahinga
I mua i ia whakamahinga, me tirotirohia te mata.
- Matawai Tirohanga: Tirohia mēnā he hononga piko, he hononga kua hē rānei, he pakaru, he kapiti, he waikura nui, he poka rānei.
- Te Hononga: Kia tino piko noa ngā hononga. Mēnā he pakari, he tohu pea tēnei i te kino o roto, i te poke rānei.
- Tirotiro Taputapu: Manatokohia kāore ngā matau i mirohia, kāore hoki ngā whakatuwheratanga i whakanuia, ā, kei te tika te mahi a ngā raka haumaru (mēnā kua whakauruhia).
b) Ngā Tikanga Whakamahinga
- Te Ara i te Mekameka: Me ara tika ngā mekameka i waenganui i ngā pūwāhi whakapiri o te waka me te utanga. Āta karohia ngā taha koi; ki te mea me whiti te mekameka i tētahi kokonga koi, whakamahia he nohoanga kokonga tiaki, he pare taha rānei hei ārai i te pakaru o ngā hononga.
- Te Whakamahi i te Ānini:
1. Āpitihia te mekameka ki ngā pū here o te waka me ngā pū here o te utanga (hei tauira, ngā mowhiti here).
2. Whakamahia he taputapu tāroaroa (he ratchet, he rīpene hiki rānei) hei tango i te ngenge, kātahi ka tāpirihia te tāroaroa-mua.
3. Me rawaka te tāroaroa-mua hei pupuri i te kawenga kia kore e neke i raro i te wiri kawe noa engari kaua rawa e neke atu i te 50% o te WLL o te mekameka i te wā e tāroaroa ana. Mā te tāroaroa rawa ka pāngia te pūnaha e te taumahatanga koretake, ā, ka kino pea te kawenga.
- Te Whakamau i ngā Pito Wetekina: Me whakau te roa o te mekameka kia kore ai e "whiua te mekameka" i te wā e kawe ana, ka kino pea te utanga, te mekameka rānei.
c) Te ōritetanga me te taurite
Mō ngā utanga taumaha, utu nui rānei, me ōrite te whakaritenga here. He mea nui te maha o ngā here me ō rātou koki (koki here). Ka heke te whai huatanga o te here i te hekenga o te koki whakapae. Ko te mea pai, me tata ngā here ki te whakapae kia kore ai e neke whakamua.
3. Ngā Whakatūpato Matua: Ngā Mea KAUA E MAHI
E whakaatu ana ngā wheako, ko te nuinga o ngā pakaru o te mekameka ehara i te mea nā ngā hapa hanga engari nā te whakamahinga hē. Kāore e taea te whakahē i te piri ki ngā whakatūpato e whai ake nei.
a) Kāore he hiki i runga i te upoko
Koinei te rerekētanga tino nui. Kāore ngā mekameka here i hangaia mō te hiki i runga. Ko te hiki he kaha hihiri e kore e taea te matapae, ā, ka taea te neke atu i ngā rohe hoahoa pūmau o ngā wāhanga mekameka kawe. He takahi nui i te haumaru te whakamahi i te mekameka here i roto i te tono hiki.
b) Āraia te Utaina Ru
Ko ngā oho ohorere, ngā pānga rānei—pērā i te tīmatanga ohorere o te taraka, te nekenga o te kawenga me te "hopu" i te mekameka—ka taea te whakaputa i ngā kaha e nui atu ana i te WLL, ka arahi ki te pakarukaru ohorere. Me kume mārie tonu ngā mekameka.
c) Ārai i te wera me te pakū
- Te wera: Ka ngaro te kaha o te maitai koranu i te wā i whakamahanatia ai ina pāngia e ngā pāmahana teitei. Āta karohia te pā atu ki ngā pūnaha whakaputa wera, ki ngā mura rānei o te whakarewa.
- Te Waro: Kaua e tōia ngā mekameka ki runga i te raima taratara, i ngā mata taratara rānei. Ka pakaru te rauemi hononga, ka whakaiti i te horahanga whakawhiti, ā, ka ngoikore te mekameka.
d) Kia tūpato ki te miro me te here
Kaua rawa te mekameka e whakamahia i roto i te āhua miro. Ka puta he taumahatanga hurihuri i te miro, kāore i hangaia te mekameka kia mau. Kaua rawa e whakamahi i ngā pona hei whakapoto i te mekameka; whakamahia he matau hopu kua whakanohoia tika ki roto i te hononga.
e) Koki Utaina
Mena ka whakamahia he mekameka i roto i te here kete, i te whakaritenga waewae-maha rānei, ka piki ake ngā kaha o ia waewae i te pikinga ake o te koki mai i te poutū. Me tatau tēnei "tauwehe koki whitiki" kia kore ai tetahi waewae e taumaha rawa.
4. Paearu Whakakapinga: Āhea me Whakamutua he Mekameka
He mea pakaru ngā mekameka. He mutunga kore te roa o te wā e whakamahia ana. He petipeti te whakamahi tonu i tētahi mekameka kua pakaru, kua tawhito rānei. Me tango tonu te mekameka mai i te ratonga, ā, me whakakapi mēnā ka kitea tētahi o ēnei āhuatanga:
a) Te whakarerekētanga āhua
- Te Roroa: Inehia te mekameka ki tētahi roa kua whakaritea (hei tauira, 10 hononga). Mena ka nui ake te roa i inehia i te whakaritenga a te kaihanga (te nuinga o te 3-5% te roa), kua totoro te mekameka, ā, kua ngaro tōna āhua i te whakamahanatia. He tohu matua tēnei mō te pakaru kei te haere mai.
- Ngā Hononga Piko, Miro rānei: Ko ngā hononga katoa e kitea ana kua piko mai i tōna papa taketake he tohu tēnei kua taumaha rawa.
b) Te Ngaronga o te Pakaru me te Wāhanga
- Te Pakaru i ngā Wāhi Whakapūmau: Inehia te diameter o te hononga i ngā wāhi e pā ana ngā hononga tetahi ki tetahi. Mena kua heke te diameter neke atu i te 10% (tirohia ngā whakaritenga a te kaihanga), me whakakapi te mekameka. Kāore e taea e te maitai angiangi te tautoko i te kawenga kua whakatauria.
- Te Whakatō me te Tāwhana: Ka hangaia e ngā tāwhana hōhonu ngā pūwāhi kukū ahotea ka tīmata ai ngā pakaru.
c) Āhua o te Mata
- Ngā kapiti: Ahakoa ngā kapiti iti i te mata o te hononga, he take tēnei hei whakakore tonu atu.
- Te Waikura Nui: Ka taea e te waikura te whakaoho i te ahotea. Mēnā he hohonu te poka o te mata, ka pakaru te mekameka.
d) Āhua o te Pūmārō
- Ngā matau: Whakakapia ngā matau mēnā kua piko te whakatuwheratanga o te korokoro, kua neke atu rānei i te 15% te whakatuwheratanga, mēnā rānei he pakaru e kitea ana i te nohoanga o te matau.
e) Ngā Raraunga Ngaro, Kāore rānei e Taea te Pānui
Mena kua ngaro te tohu tohu a te kaihanga, te tohu WLL rānei, ā, kāore e taea te tautuhi tika i te mekameka, me tango atu i te ratonga. Kāore e taea te whakamahi haumaru i te mea kāore e taea te tautuhi.
