Whakamātautau Pēki
I runga anō i ngā paerewa OCIMF, he mea nui kia whakahaerehia he whakamātautau kaha pēhi i te wini Tūmau i mua i te tukunga, i ia tau, ā, whai muri i ngā whakatikatika, i ngā kaupapa nui rānei ka pā ki te kaha pēhi. I runga i ngā putanga o ēnei whakamātautau, ka whakatikatikaina te pēhi kia eke ki te kaha pēhi o te 60% ki te 80% o te kawenga pakaru iti rawa (MBL) o te taura tūmau. Mā tēnei whakatikatika ka whakarite mēnā ka nui ake te kaha o waho i te kaha pēhi kua tohua, ka wetekina aunoa te wini Tūmau, ā, ka ārai i tētahi pakaru, i tētahi kino rānei ki te wini Tūmau.
Ataata mō te whakamātautau i te kaha o te aukati:
Te Whakamātautau me te Whakarite i te Kaha Pēhi
Tīmata mā te arotake i te tiwhikete taura me ētahi atu mōhiohio e tika ana, me ngā inenga o te mara, hei kohikohi i ngā raraunga hukarere e tika ana mō ngā tataunga. Me whai wāhi te jack me te winch here, he ine pēhanga kei roto, hei whakau i te jack maroke, hei whakamahi rānei i ngā pūtu here.
Ko te tātai tatau penei: T = FxLI/L2 (Kn).
I roto i tēnei tātai, ko T te tohu o te kaha whakapūtanga kua tatauhia (i roto i te Kn), me whakatau i runga i te kaha pakaru iti rawa o te taura o te kaipuke. Mā tēnei tātaitanga ka puta te pānui kaha whakapūtanga e rite ana ki te kaha aukati e hiahiatia ana, arā, 60%, 80% rānei o te kaha pakaru o te taura. Ko F te tohu o te kaha aukati o te wini here (i roto i te Kn). Ko Ll te tawhiti mai i te pokapū o te roera wini here ki te pokapū o te taura, i tatauhia hei tapeke o te radius roera o roto me te radius taura. Ko L2 te tohu o te tawhiti whakapae mai i te pokapū o te whāriki wiri ki te tuaka pokapū.
Tukanga Whakamātautau:
1. Whakahaerehia te wini here hei whakakore i te makuku, te hinu, me ētahi atu matū rānei ka whakararu i te mahi a ngā papa pēki.
2. Honoa tika te taputapu whakamātautau ki te wini here, kia tino whakau ngā pēki ki ngā taumata paerewa, kātahi ka wetekina te mamau o te wini.
3. Whakamahia te hūnga hei pēhi, ā, aroturukihia te pānui o te ine pēhanga i te wā ka tīmata te paheke o te pērai, me te tuhi i te uara i kitea.
4. Mena ka heke te pānui i raro i te uara kua whakaritea, he tohu tēnei kāore i te rawaka te kaha o te parai, ā, me whakakaha, me whakatika rānei te parai, ā, muri iho ka whakamātautau anō.
5. Mena ka ōrite te pānui ki te uara kua tatauhia, ka whakaūtia kei te tutuki te kaha parai i ngā paearu kua whakatūria.
6. Ki te kore te wini here e paheke i te wā e nui ake ana te pānui o te tīki i te uara kua tatauhia, e tohu ana tēnei he tino piri te pērai, ā, ka nui rawa te kaha pērai. I tēnei wā, me whakaiti te kaha pērai mā te whakarerekē i te tīwiri pērai, ā, muri iho ka whakamātautau anō.
Ko te nuinga o ngā waka ka mahi i ā rātou ake whakatikatika i te kaha o te pērai, mā te whakarerekē i te tīwiri here i runga i te kakau pērai hei whakahaere i te pūmau o te pērai kia pai ai te kaha.
Mō ngā kakau pērai kāore he tīwiri here, ka taea te tautuhi i te tūranga i muri i te whakakīkītanga o te pērai (e rite ana ki te kaha pērai e hiahiatia ana) me te tohu i te kakau pērai me te whitiki pērai i taua wāhi (ka hangaia he tohu here ki te tīwiri pērai). I ngā mahi ā muri ake nei, mā te whakarite i ngā tohu o runga me raro ka tohu ko te kaha pērai i tēnei taumata e rite ana ki te kaha pērai kua whakaritea.
Kia oti te whakamātautau parai, me whakaatu mārama te rā o te whakamātautau me te kaha parai i inehia ki runga i te wini here, ā, me tuhi hoki ki roto i te rārangi tiaki taputapu here.
Ngā Mahi Haumaru Taunga
Haunga te whakamātautau me te whakarerekē i te kaha o te pērai i ia wā, me aro atu hoki ki ngā āhuatanga e whai ake nei i te wā e mau ana te waka:
Te Āhuatanga o te Taunga:He mea nui te ngāwari o ngā taura here ki te tohatoha i te kaha katoa e tukuna ana e te kaipuke ki waenga i ngā taura here. Hei tauira, mēnā e rua ngā taura here he rite te rahi me te rauemi e herea ana ki te tauranga i te ahunga kotahi engari he rerekē te roa—ko tētahi he rua te roa i tētahi—ka taea e te taura poto te tu atu i te rua hautoru o te kawenga, ko te taura roa ia ka tu atu i te kotahi hautoru anake. Nō reira, he mea tika kia whakamahia ngā taura here he rite te roa i ngā wā katoa e taea ai.
Mēnā he rite te roa o ngā taura here e rua, he rite te kaha whati, ā, he rite te ahunga engari he rerekē ngā rauemi i hangaia ai—pērā i te taura waea maitai he 1.5% te roa me te taura muka hangai he 30% te roa—ka kore e tino ōrite te tohatoha kawenga. Ka taea e te taura waea maitai te kawe i te 95% o te kawenga, ko te taura muka ia ka tautoko i te 5% anake. Nō reira, he mea nui kia whakamahia ngā taura o te rauemi kotahi mō ngā taura here i te ahunga kotahi.
He mea nui kia mōhiotia ko te whakarite i te haumaru o te kaipuke i te wā e here ana (te herenga haumaru) ehara i te mea ko te mahi tahi me te ōrite anake engari ko te māramatanga whānui ki ngā taputapu here o te kaipuke, te māramatanga pakari ki ngā mātāpono herenga, me te whakamahere me te whakatinanatanga tino tika. Ko te tukanga pupuri i te tūranga o te kaipuke i te taunga ka tīmata i muri i te mau o te kaipuke, e tohu ana i te tīmatanga o ngā mahi whakatere moana tonu.
Te Kaha Pēki o te Winch Taunga:He rerekē te kaha aukati o te wini here mō ia waka, ā, he mea hanga i runga i te kaha "whakakore taura" e pā ana ki te taura. Ka pāngia tēnei kaha e te maha o ngā paparanga taura me te ahunga takai. Ko te nui o ngā paparanga taura i runga i te pahu he pānga nui ki te kaha aukati o te pūnaha here. Mō ngā mīhini here kāore he pahu wehewehe, ko te kaha aukati ka whakaritea mō tētahi maha o ngā paparanga. Nō reira, he mea nui kia whakarite kia pai te takai o ngā taura ki runga i te pahu, kaua e kohikohi ki tētahi taha, nā te mea ka taea e tēnei te whakaiti i te kaha aukati. Mō ngā wini taura kua whakauruhia ki ngā pahu wehewehe, he mea nui kia kaua e neke atu i te kotahi te paparanga taura i runga i te pahu kaha hei ārai i te whakahekenga o te kaha aukati.
He mea nui te takai tika o te taura, nā te mea ki te kore e tika te takai ka heke te kaha aukati tae atu ki te 50%.
Te Whakamahinga Pēki Hē:He maha ngā wā ka hē te whakamahi a ngā kaimahi i ngā pēraki hei wetewete i te taura ina pēhia ana, he huarahi hē tēnei. Ka taea e tēnei mahi te arahi ki te pakaru kore taurite o te whitiki pēraki, ā, ka tūpono he mōrearea haumaru nā te mea kāore e taea te whakahaere. Mēnā ka pāngia ohoreretia he kawenga taurite ki te taura kāore i wetewetehia, ka pakaru pea, ka hua ake he aituā. Ko te tikanga tika ko te whakauru i te mamau me te whakamahi i te mana hei wetewete mārire i te taura.
Te Tikanga Kume Puranga Taura Nairona:I te wā e whakamau ana i te taura nairona ki te pou, kaua e whakawhirinaki ki te pona "∞" anake hei whakau. Engari, kia rua ngā hurihanga (ko ētahi e tūtohu ana kia kotahi te hurihanga, engari kaua e neke atu i te rua) hei kukume i te taura i te taha o te kaipuke, ā, muri iho ka hanga he pona "∞" (mō ngā pou here nui ake) ka takai rānei i ngā pou e rua i mua i te hanga i te pona "∞" (mō ngā pou here iti ake). Mā tēnei tikanga ka pai ake te whakahaere i te taura, ā, ka whakarei ake i te haumaru.
Rohe Mōrearea i te Wā e Pakaru ana te Taura:Ko te āhuatanga tino mōrearea o ngā taura muka hangai ka puta ina whati te taura, ā, ka hoki whakamuri ohorere. Ina motu te taura kua pēhia, ka tukuna te kaha kua rongoatia, ka tere te hoki whakamuri o te wāhanga i waenga i te pūwāhi whati me te pūwāhi whakahaere. Ko ngā tāngata kei roto i te rohe whakahoki ka tūpono ki te whara kino, ki te mate rānei. Nō reira, he mea nui kia karohia e ngā kaiwhakahaere taura tēnei wāhi mōrearea, inā koa kei raro te taura i te taumahatanga nui, nā te mea ka whati ohorere ngā taura muka hangai, me te kore whakatūpato.
Aratohu Haumaru mō te Taunga:Kaua te taura o te pane o te pahu e whakahaeretia e te tangata kotahi. Me whai atu tētahi atu tangata hei tango, hei whakarato rānei i te wātea o te taura hei āwhina i te kaiwhakahaere e whakahaere ana i te pahu. Ina whakamahi ana i ngā taura waea, i ngā taura nairona rānei, he mea nui kia mau tonu te tawhiti haumaru mai i te pahu, nā te mea ka "peke" te taura, ā, ka tūpono pea te whara o ō ringaringa. Me mau tonu te tawhiti haumaru mai i te taura.
