1. Ka palena haawe hana no na kaulahao hao
Inā ʻoe e halihali i nā mīkini, hoʻohana i nā kaulahao huki, a i ʻole i ka ʻoihana logging, pono e ʻike i nā palena haʻahaʻa hana o ke kaulahao āu e hoʻohana nei. Loaʻa i nā kaulahao ka palena haʻahaʻa hana- a i ʻole WLL- o kahi hapahā o ko lākou ikaika haki (ka nui o ka ikaika e hiki ai i nā kaulahao ke kū ma mua o ka haki ʻana).
Hoʻoholo ka pae kaulahao a me ke anawaena i ka palena haʻahaʻa hana o ke kaulahao. Hoʻopili ʻia ke kaulahao me ka māka a me ka nui i hiki iā ʻoe ke hoʻoholo i kāna WLL me ka hoʻohana ʻana i kēia pakuhi.
2. Nā ʻano kaulahao
ʻO ka papa 30 he kaulahao waiwai nui. ʻIke pū ʻia ʻo Grade 30 Proof Coil Chain, hoʻohana ka poʻe i kēia huahana i nā ʻano hana like ʻole a me nā hana, me ka hana māmā, nā kaulahao pale, a me ka ʻoihana moana. ʻAʻole palekana no ka hāpai ʻana i luna. Hoʻopili ʻia ke kaulahao papa 30 me ka 3, 30, a i ʻole 300.
Kapa ʻia ʻo Grade 43 High Test Chain a i ʻole Grade 43 Tow Chain, he mea maʻamau kēia i ka ʻoihana huki a me ke kālai lāʻau. Mai hoʻohana i kēia kaulahao no ka hāpai ʻana i luna. Aia kēia kaulahao i nā hoʻolālā i hoʻohana ʻia me ka 43 a i ʻole G4.
ʻO ka Papa 70 Transport Chain, i kapa ʻia ʻo "Grade 70 Truckers Chain," hana i ka mālama ʻana i nā ukana no ka huki ʻana ma ke alanui. Mai hoʻohana i kēia kaulahao no ka hāpai ʻana i luna. Aia kēia kaulahao i nā hoʻolālā i hoʻohana ʻia me ka 7, 70, a i ʻole 700.
Hana ʻo Papa 80 Alloy Chain no ka hāpai ʻana ma luna o ke poʻo ma muli o kāna hoʻolālā wela. Hoʻohana pinepine ka poʻe i kēia ʻano kaulahao ma ke ʻano he kaulahao huki hana kaumaha. Hoʻokomo ʻia nā kaulahao papa 80 me ka hoʻohana ʻana i ka 8, 80, a i ʻole 800.
Manaʻo ʻia ke kaulahao maikaʻi maikaʻi, hāʻawi ia ma kahi o 25% kiʻekiʻe ka palena o ka hana ma luna o ke kaulahao 80. He palekana no ka hāpai ʻana i luna. Loaʻa i nā kaulahao papa 100 nā hoʻolālā i hoʻopaʻa ʻia me kahi 10 a i ʻole 100.
ʻO kahi huahana hou ma ka mākeke, ʻoi aku ka ikaika o ke kaulahao 120 ma mua o 50% ma mua o ke kaulahao Grade 80 a ʻoi aku ka ikaika o 20% ma mua o ke kaulahao Grade 100. ʻOi aku ka pale ʻana i ka abrasion ma mua o nā kaulahao Grade 80 a me Grade 100. He palekana no nā mea hoʻokiʻekiʻe ma luna.
3. E aʻo hou e pili ana i nā ʻokoʻa ma waena o nā papa 70, 80 a me 100 ma aneʻi:
ʻO kahi nīnau maʻamau i lohe ʻia e kā mākou hui kūʻai mai nā mea kūʻai mai e pili ana i kā mākou huahana kaulahao "He aha nā ʻokoʻa ma waena o ke kaulahao 70, 80, 100, a me 120?" Wehewehe mākou i nā ʻokoʻa ma waena o kēia mau ʻāpana a me nā kaulahao āu e hoʻohana ai e like me kāu pono.
Hana ʻia ke kaulahao papa 70 i ke kila kalapona wela. ʻIke ʻia hoʻi ʻo "ke kaula kaʻa kaʻa," hoʻohana nā kānaka i ka papa 70 ma ke ʻano he nakinaki i nā kaʻa kaʻa ma luna o ke alanui.Mai hoʻohana i kēia kaulahao no ka hāpai ʻana i luna.
Loaʻa kēia ʻano i kahi hoʻopau chromate gula no laila maʻalahi ke ʻike. Hoʻokō pū ʻia ʻo California Highway Patrol a me nā koi DOT. ʻO nā mea hoʻohana no kēia kaulahao, ma waho o ka lawe ʻana, e komo pū me ka huki ʻana, ke kālai ʻana, nā ʻaila hinu, a me nā noi palekana.
Aia kēia kaulahao i nā hoʻolālā i hoʻopaʻa ʻia me 7, 70, a i ʻole 700.
ʻO ke kaulahao 80 he kaula hao i hoʻomaʻamaʻa ʻia me ka ikaika kiʻekiʻe i ke kaupaona ʻana. ʻO kona ikaika ka palekana no ka hāpai ʻana a me ka hāpai ʻana i nā maʻa. He mea maikaʻi loa ia no ka hoʻohana ʻana e like me ka hoʻihoʻi, palekana, a me nā kaulahao huki.
Ke lilo nei kēia kaulahao i mea maʻamau i ka ʻoihana kaʻa kaʻa paʻa no ka hoʻopaʻa ʻana i nā ukana ʻoihana kaumaha. No ka mea, hoʻolako pinepine ʻia kēia mau ʻano kaulahao me kahi ʻano kikoʻī o ka clevis grab hook, a ʻaʻole ʻae ʻia nā hui kaulahao no ka hāpai ʻana i luna.
Aia kēia kaulahao i nā hoʻolālā i hoʻopaʻa ʻia me 8, 80, a i ʻole 800.
He huahana hou aʻe ka pae 100 kaulahao a ke kaulana nei ma ke ʻano he pani no ke kaulahao papa 80. Manaʻo ʻia ka maikaʻi o nā mea hana, hāʻawi ia ma kahi o 25% kiʻekiʻe o nā palena haʻahaʻa hana ma mua o ka papa 80 a hana no nā noi hoʻokiʻekiʻe ma luna.
Hoʻohana hou ka poʻe i ka papa 100 ma luna o ka papa 80 no ka hoʻopaʻa ʻana i nā ukana palahalaha. Loaʻa i kēia kaulahao kahi ikaika hou a me ka liʻiliʻi liʻiliʻi ʻaʻole e kū i ka palena haʻahaʻa hana.
Eia nō naʻe, no ka mea, ua hoʻolako ʻia kēia mau kaulahao me kahi ʻano kikoʻī o ka clevis grab hook, a ʻaʻole ʻae ʻia nā hui kaulahao no ka hāpai ʻana i luna.
Aia kēia kaulahao i nā hoʻolālā i hoʻopaʻa ʻia me 10, 100, a i ʻole 1000.
ʻO ka pae 120 kaulahao he ʻano hou aʻe o ke kaulahao hana kiʻekiʻe, e hāʻawi ana i ka ikaika kiʻekiʻe o ka ʻoihana. Hoʻokumu ke ʻano loulou square i ka hoʻopili hou ʻana ma waena o nā ʻaoʻao e pili ana i nā loulou, e hōʻemi ana i ke kaomi ma ke kaulahao.
Hoʻololi kēia i nā palena haʻahaʻa hana he 50% kiʻekiʻe ma mua o ka papa 80, a he 20% ʻoi aku ka kiʻekiʻe ma mua o ka papa 100. Hana ʻia ke kaulahao 120 no ka hāpai ʻana i luna. He mea nui e hoʻomaopopo e like me ka papa 80 tie down chain assemblies a me Grade 100 tie down chain assemblies, ʻaʻole palekana nā hui kaula no ka hāpai ʻana i luna ma muli o ke ʻano o nā makau i hoʻohana ʻia.
ʻO kēia ʻano kaulahao he ʻulaʻula uliuli e hiki ai ke ʻike maʻalahi iā lākou.
Ma waho o ke ʻano o ke kaulahao, pono nā mea āpau e pili i nā kūlana i hoʻonohonoho ʻia e ka National Association of Chain Manufacturers (NACM), ʻo ia hoʻi:
- Mai lawe a hoʻokuʻu paha i nā ukana i hāpai ʻia ma luna o nā kānaka.
- Ke nānā ʻana i nā kaulahao i kēlā me kēia manawa no nā māwae, nā ʻōpala, nā lole, elongation, nicks, a me ke kūpono.
- Hiki ke hoʻemi i ka hana o ke kaulahao i ka nui o ka mahana a i ʻole ka ʻike ʻana i nā kaiapuni hana kemika e like me nā waikawa a i ʻole nā wai corrosive.
- E kūkākūkā me ka mea hana o ke kaulahao inā e holo ana nā kaulahao ma waho o ka pae wela i ʻōlelo ʻia (-40 °F a 400 °F).
- Wehe i ke kaulahao mai ka lawelawe ʻana inā ʻoi aku ka mānoanoa o kekahi ʻāpana ma ka loulou ma mua o ka waiwai haʻahaʻa i helu ʻia.
- I ka hui ʻana i nā kaulahao a i ʻole nā ʻano ʻāpana, pono e helu ʻia nā mea āpau ma ka palena haʻahaʻa hana o ka mea haʻahaʻa i helu ʻia a kaulahao paha.
- E nānā i kā mākou koho ʻana i nā kaulahao kaʻa 70, a me nā maʻa kaulahao.
