1. E ai ki te taiao whakamahinga
a.I te wā e whiriwhiri ana i tētahi kawe wira e tika ana, ko te mea tuatahi hei whakaaroaro ko te taumaha o te kawe wira. Hei tauira, i roto i ngā hūpāmakete, kura, hōhipera, whare tari me ngā hōtēra, he pai te papa, he maeneene, ā, he māmā te nuinga o ngā taonga e haria ana, ko te tikanga ka taea e ia kaihuri te kawe i te 10 ki te 140kg. Nō reira, ko te kōwhiringa pai ko te kawe wira whakakikorua i hangaia mā te whakamahi i te tukanga tā ki runga i tētahi pereti maitai angiangi (2-4mm). He māmā, he ngāwari, he koretake hoki tēnei momo kawe wira.
b.I ngā wāhi pēnei i ngā wheketere me ngā whare putunga he nui ake te nekeneke o ngā utanga, ā, he taumaha ake hoki te kawenga (280-420kg), ka tūtohu mātou kia whakamahia he kawe wira i hangaia ki te pereti maitai matotoru 5-6mm.
c.Mena ka whakamahia mō te kawe i ngā mea taumaha ake pērā i ngā mea e kitea ana i roto i ngā wheketere kakahu, i ngā wheketere motuka, i ngā wheketere mīhini rānei, nā te nui o te kawenga me te roa o te hikoi, me kaha ia mīhini hurihuri ki te kawe i te 350-1200kg, ā, me hanga mā te whakamahi i tētahi kawe wira pereti maitai matotoru 8-12mm. Ka whakamahia e te kawe wira neke he peera pōro papatahi, ā, ka whakanohoia te peera pōro ki te pereti o raro, e āhei ai te mīhini hurihuri ki te kawe i te kawenga taumaha me te pupuri tonu i te hurihanga ngāwari me te ātete pānga. Ka tūtohu mātou kia whakamahia ngā wira hurihuri i hangaia ki te nairona whakapakari (PA6) super polyurethane, ki te rapa rānei. I runga i ngā hiahia tono motuhake, ka taea hoki te whakakikorua, te rehu rānei ki te maimoatanga ātete waikura, me te hoatu hoki i tētahi hoahoa ārai takai.
d.Ngā taiao motuhake: he nui te taumahatanga o ngā wira i ngā wāhi makariri me te pāmahana teitei, ā, i ngā pāmahana tino kino, ka tūtohu mātou i ngā rauemi e whai ake nei
· pāmahana iti i raro i te -45℃: polyurethane
· ngā pāmahana teitei e tata ana ki te 230℃, neke atu rānei: ngā wira hurihuri motuhake ātete wera
2.E ai ki te kaha o te kawe
I te wā e whiriwhiri ana i te kaha kawe o ngā wira hurihuri, me whai whakaaro ngā kaiwhakamahi ki ngā tawhā haumaru motuhake. Ka whakamahia e mātou ngā wira hurihuri e whakamahia whānuitia ana hei tauira, engari me whiriwhiri i runga i ngā tikanga e rua e whai ake nei:
a.3 ngā wira e pikau ana i te taumaha katoa: Me whakairi tētahi o ngā wira. He pai tēnei tikanga mō ngā mahi e kaha ake ai te nekehanga o ngā wira i runga i ngā āhuatanga whenua ngoikore i te wā e neke ana i ngā taonga, i ngā taputapu rānei, inā koa he nui ake, he taumaha ake ngā taumaha katoa.
b.4 ngā wira e mau ana i te taumaha katoa o te 120%: He pai tēnei tikanga mō ngā āhuatanga whenua e pai ana, ā, he iti noa te pānga ki ngā wira i te wā e nekehia ana ngā taonga, ngā taputapu rānei.
c.Tātaihia te kaha kawe: Hei tātai i te kaha kawenga e hiahiatia ana e ngā kaihurihuri, me mōhio ki te taumaha mate o ngā taputapu tuku, te kawenga mōrahi me te maha o ngā wira hurihuri me ngā wira hurihuri e whakamahia ana. Ko te kaha kawenga e hiahiatia ana mō te wira hurihuri, mō te wira hurihuri rānei ka tātaihia penei:
T= (E+Z)/M×N
---T= te taumaha uta e hiahiatia ana mō te wira hurihuri, mō te wira hurihuri rānei
---E= taumaha mate o ngā taputapu tuku
---Z = kawenga mōrahi
---M= te maha o ngā wira hurihuri me ngā wira hurihuri e whakamahia ana
---N= Tauwehenga haumaru (tata ki te 1.3 - 1.5).
Me aro nui ki ngā wā ka pāngia ngā wira e te pānga nui. Kaua e whiriwhiria he wira he nui te kaha ki te pikau kawenga anake, engari me whiriwhiri hoki he hanganga tiaki pānga kua hangaia mōna. Mena e hiahiatia ana he parai, me whiriwhiri ngā wira he kotahi, he takirua rānei ngā parai.
