He whitiki maitai kore waikura totoka te rawhi ngongo pūtu totoka, he taha pōtakataka, he raro maeneene hei ārai i te kino o te ngongo; me te hanganga tino kaha hei whakarato i te kaha teitei mō te hiri pai rawa atu, he mea tino pai mō ngā mahi taumaha e hiahiatia ana he kaha whakakī nui me te tiaki i te waikura.
He mea hanga ngā here ngongo pūtu totoka ki te rino pīni me te maitai kore waikura. Kua wehea te rino pīni ki te konutea mā, ki te konutea kōwhai. Ko ngā whānui whānui e whakamahia whānuitia ana ko te 18MM, 20MM, 22MM, 24MM me te 26MM. E whakamahi ana ngā tīwiri i te paerewa o te ao 8.8, he nui ake te taipana me te kaha ake. He whānui te whakamahinga i ētahi wāhi e hiahia ana ki te kaha whakakī kaha. He whānui te whakamahinga i roto i ngā motuka, ngā tarakihana, ngā forklift, ngā locomotive, ngā kaipuke, te keri maina, te hinu, te matū, te rongoā, te ahuwhenua me ētahi atu wai, hinu, mamaoa, puehu, me ētahi atu. He hononga tino pai.
Whakaahuatanga:
1) Te Whānuitanga me te Matotoru
He rerekē te whānui me te matotoru i ngā mea whakakikoruatia ki te konutea me te mea kowiri tira
Mō te mea whakakikoruatia ki te konutea (W1), ko te whānui me te matotoru he 18*0.6/20*0.8/22*1.2/24*1.5/26*1.7mm
Mō te kowiri tira, ko te whānui me te matotoru he 18*0.6/20*0.6/22*0.8/24*0.8/26*1.0mm
2) Wāhanga
E whā ngā wāhanga o tēnei, arā: te whitiki/piriti/poro/tuaka.
3) Rauemi
E whā ngā raupapa rauemi e whai ake nei:
①W1 raupapa (kua whakakikoruatia ngā wāhanga katoa ki te konutea)
②W2 raupapa (he kowiri tira te whitiki me te piriti 201/304/316, he konutea ētahi atu wāhanga)
③W4 raupapa (he kowiri tira katoa ngā wāhanga 201/304)
④W5 raupapa (he kowiri tira te katoa o ngā wāhanga 316)
Tono
He tino rongonui ngā rawhi ngongo pūtu totoka hei whakamahi whānuitia i roto i ngā motuka, ahumahi, ahuwhenua, paipa motuka, paipa motuka, paipa wai, paipa whakamatao me ētahi atu.
Ko te rawhi ngongo kotahi te mea i hangaia mō ngā mahi e tika ana kia tutuki i ngā rawhi ngongo ngā whakaritenga taumaha. Ko te tikanga o te rawhi kaha teitei 8.8 te tohu ka taea te whakau i tēnei rawhi mā te whakamahi i ngā taputapu paerewa ā-ringa, hau, hiko rānei, ā, ka taea e ngā taha hurihuri te tiaki i te ngongo mai i te kino.
