ʻO nā loulou a me nā apo he ʻano maʻalahi o nā lako hana rigging, nona hoʻokahi wale nō loop metala. Ua ʻike paha ʻoe i kahi apo nui e waiho ana a puni ka hale kūʻai a i ʻole kahi loulou oblong e kau ana mai kahi makau crane. Eia nō naʻe, inā he mea hou ʻoe i ka ʻoihana rigging a ʻaʻole paha i hoʻohana i kahi loulou a apo paha ma mua, ʻaʻole paha maopopo loa ke kumu he mea nui kēia mau mea hana maʻalahi i ka wā e hoʻopaʻa ai i kahi hāpai ma luna.
Ua ʻike mākou i ka wā e pili ana i nā loulou a me nā apo, nui ka ʻike kikoʻī a me ka ʻike loea i loaʻa ma ka pūnaewele. Eia nō naʻe, ʻaneʻane ʻaʻohe ʻike laulā e pili ana i ke ʻano o kēia mau mea hana a me kā lākou hoʻohana ʻia.
No nā mea kūʻai aku ma waho e ʻike hou ana i nā huahana e pili ana i ka rigging, pono e hoʻomaka me ka ʻike maʻamau a me ka ʻike e pili ana i ka noi ma mua o ke komo ʻana i nā mea paʻakikī. ʻO ia ke kumu i kākau ai mākou i kēia ʻatikala.
Ma kēia ʻatikala, hiki iā ʻoe ke manaʻo e aʻo:
• He aha nā loulou a me nā apo a me kā lākou hoʻohana ʻia
• He aha nā ʻano loulou a me nā apo like ʻole
• Nā māka / ʻike no nā loulou a me nā apo
• Ka wehe ʻana i nā loulou a me nā apo mai nā pae lawelawe
1. He aha nā Loulou a me nā Apo?
He mau mea maʻalahi akā koʻikoʻi nā loulou a me nā apo i nā hana hāpai a me nā rigging. He mau mea hana loop pani ʻia lākou—e like me ka maka—i hoʻohana ʻia e hana i nā wahi pili i nā ʻākoakoa rigging a me sling e komo pū ana menā kaulahao kaulahao, nā maʻa kaula uea, nā maʻa ulana, a pēlā aku.
Hoʻohana pinepine ʻia nā loulou a me nā apo ma ke ʻano he wahi hoʻohui i lokonā ʻākoakoa kaula wāwae he nui—ʻo ke kaulahao a i ʻole ke kaula uea. Hiki ke hoʻohana ʻia lākou ma ke ʻano he wahi hoʻohui no hoʻokahi, ʻelua, ʻekolu, a ʻehā paha mau hoʻonohonoho wāwae-sling.
ʻO nā loulou haku a me nā apo—nā loulou haku ʻōniʻoniʻo, nā apo haku, a me nā loulou haku ʻano pea—ua kapa ʻia hoʻi he mau apo hōʻiliʻili a i ʻole nā loulou hōʻiliʻili, ʻoiai lākou e "hōʻiliʻili" i nā wāwae maʻa he nui i loko o hoʻokahi loulou.
Ma waho aʻe o ka hoʻohana ʻana i nā ʻākoakoa sling, hiki ke hoʻohana ʻia nā loulou a me nā apo ma ke ʻano he wahi hoʻohui ma waena o nā ʻāpana ʻelua o kahi ʻākoakoa rigging. No ka laʻana, hiki iā ʻoe ke hoʻohana i kahi loulou a apo paha e hoʻohui i kahi:E hoʻopaʻa i ke kaulahao i ka makau crane,E hoʻopaʻa i ka makau,Loulou i kahi makau hoʻopaʻa
2. Nā ʻAno Loulou a me nā Apo
Aia kekahi mau ʻano loulou a me nā apo like ʻole e hiki ke hoʻohana ʻia i loko o kahi ʻākoakoa. ʻO nā ʻano loulou a me nā apo i hoʻohana pinepine ʻia:Nā loulou haku ʻōniʻoniʻo,Nā ʻaha kūkā loulou nui,Nā loulou ʻano pear,Nā apo haku,Nā loulou hoʻohui
Hiki ke hoʻohana ʻia nā loulou haku ʻōblong e hoʻohui i kahi shackle i ka makau crane, kahi makau i ka shackle, a me nā ʻano ʻākoakoa rigging like ʻole.
ʻO nā ʻāpana liʻiliʻi he ʻelua mau loulou hoʻopili haku i hoʻopaʻa ʻia i kahi loulou haku oblong. Ma kahi o ka hoʻopaʻa ʻana i nā wāwae ʻehā i kahi loulou haku, hiki ke hoʻokaʻawale ʻia ma waena o nā loulou ʻelua.
ʻO ka hoʻohana ʻana i nā ʻāpana liʻiliʻi e kōkua i ka hoʻemi ʻana i ka nui o ka loulou haku—hiki i nā loulou haku nui loa ke piʻi aʻe i 3 ʻīniha ke anawaena—me ka mālama ʻana i kahi Palena Ukana Hana (WLL) e like me kahi loulou haku nui aʻe.
ʻO ke ʻano pea o kēia mau loulou e kūpono ai no ka hoʻohana ʻana me nā lou haiki loa. I kekahi mau hihia, ʻoi aku ka paʻa o kahi loulou ʻano pea ma mua o kahi loulou haku oblong, kahi e hoʻopau ai i ka neʻe ʻana o ka ukana mai kēlā ʻaoʻao a i kēia ʻaoʻao ma luna o ka makau.
ʻO ke ʻano poepoe o ke apo haku e hoʻolilo ia i mea kūpono ʻole ma mua o kahi loulou haku oblong no ka hoʻopili ʻana i nā makau crane nui a hohonu. Hoʻohana pinepine ʻia nā apo haku i nā hale hana hana a i ʻole nā hale hana mīkini liʻiliʻi a ʻaʻole hoʻohana pinepine ʻia. I nā hihia he nui, hiki ke hoʻopili ʻia kahi loulou haku oblong.
Hiki ke hoʻopili ʻia nā loulou hoʻopili me ka mīkini a i ʻole ka wili ʻia a hoʻohana nui ʻia e hoʻopili i kahi ʻāpana o ke kaulahao i kahi loulou nui a i ʻole i kahi mea kūpono. Hiki ke hoʻohana ʻia hoʻi lākou e hana i kahi pilina ma waena o nā loulou nui, nā makau, a i ʻole nā ʻāpana lako ʻē aʻe.
ʻO nā loulou hoʻopili i wili ʻia, e like me nā loulou ʻē aʻe a pau i loko o ke kaulahao, ua hoʻopili ʻia i ka loulou nui a i ʻole ke kūpono hope a hoʻopili ʻia e hana i kahi pilina.
ʻO ke kiʻi i hōʻike ʻia ma kēia ʻāpana e hōʻike ana i ʻelua mau ala like ʻole e hiki ai ke hoʻohana ʻia kahi loulou hoʻopili i hoʻopaʻa ʻia. Ma ke kiʻi hema, ua hoʻopili mau ʻia ka loulou i kahi makau maka a hoʻohana ʻia e hoʻohui i ka hāmeʻa i kahi makau wili. Ma ka ʻākau, hoʻohana ʻia nā loulou hoʻopili i hoʻopaʻa ʻia e hoʻopaʻa i nā wāwae kaulahao a me nā makau hopu i ka loulou haku.
Ua ʻākoakoa a wehe ʻia ʻo Hammerlok®
ʻEkolu mau inoa lama maʻamau no nā loulou hoʻopili mechanical:
• Hammerlok® (hōʻailona CM)
• Kuplex® Kuplok® (hōʻailona Peerless)
• Lok-a-Loy® (hōʻailona Crosby)
ʻO Kuplex® Kupler®, he huahana Peerless hoʻi, kekahi ʻano loulou hoʻopili mechanical maʻamau. He ʻano ʻokoʻa iki ke ʻano o kēia mau loulou hoʻopili e like me ke kaulahao. Hoʻokahi wale nō hapalua kino e hana ʻia ai kahi pilina me ka pine ukana a me ka pine paʻa. No ka mea ʻaʻohe ʻelua hapalua kino, ʻaʻole e hoʻopili ka Kuplex® Kupler® ma ke kikowaena.
ʻO ka ʻākoakoa ʻana o ke kaulahao me ka hoʻohana ʻana i kekahi mau loulou Kuplex® Kupler®
3. Nā Loulou a me nā Apo Nā Māka / ʻIke
Wahi a ASME B30.26 Rigging Hardware, pono e hōʻailona paʻa ʻia kēlā me kēia loulou, ka master link subassembly, a me ke apo e ka mea hana e hōʻike:
• Ka inoa a i ʻole ka hōʻailona kālepa o ka mea hana
• Ka nui a i ʻole ka ukana i helu ʻia
• Papa, inā pono e ʻike i ka ukana i helu ʻia
4. Wehe ʻana i nā Loulou a me nā Apo Mai nā Kūlana Hana
I ka wā o ka nānā ʻana, e wehe i nā loulou, nā ʻāpana loulou nui, a me nā apo mai ka lawelawe inā loaʻa kekahi o nā kūlana i helu ʻia ma ASME B30.26 Rigging Hardware.
• Palapala hōʻoia i nalowale a hiki ʻole ke heluhelu ʻia
• Nā hōʻailona o ka hōʻino ʻia ʻana o ka wela, me ka wili ʻana o ka weld a i ʻole nā kuʻi ʻana o ke arc
• Ka nui o ka lua a i ʻole ka palaho
• Nā ʻāpana hāpai ukana i pelu ʻia, wili ʻia, hoʻopōʻino ʻia, kīkoʻo ʻia, hoʻolōʻihi ʻia, māwae ʻia, a haki paha
• Nā ʻoki nui a i ʻole nā ʻoki liʻiliʻi
• He 10% ka emi ʻana o ka nui kumu a i ʻole ka nui papa inoa ma kekahi wahi
• Hōʻike o ka wili ʻana a i ʻole ka hoʻololi ʻana i ʻae ʻole ʻia
• Nā kūlana ʻē aʻe, me nā pōʻino i ʻike ʻia e hoʻoulu ai i ke kānalua e pili ana i ka hoʻomau ʻana o ka hoʻohana ʻana
Inā loaʻa kekahi o nā kūlana i luna, pono e wehe ʻia ka hāmeʻa mai ka lawelawe ʻana a e hoʻihoʻi ʻia no ka lawelawe inā/a i ʻāpono ʻia e kekahi kanaka kūpono.
5. Ke kāʻei nei
Lana ko mākou manaʻo ua kōkua kēia ʻatikala e hāʻawi iā ʻoe i kahi ʻike pae kumu o ke ʻano o nā loulou a me nā apo, nā mea a lākou e hoʻohana ʻia ai, a me nā pae ʻike a me ka nānā ʻana i nā lako paʻa ASME B30.26.
I ka hōʻuluʻulu ʻana, lawelawe nā loulou a me nā apo ma ke ʻano he mau wahi hoʻohui i loko o kahi ʻaha hoʻopaʻa a i ʻole ka ʻaha hoʻopaʻa wāwae he nui. ʻOiai he nui nā ʻano loulou a me nā apo like ʻole i hoʻohana ʻia i ka hoʻopaʻa ʻana, ʻo nā loulou haku oblong ka mea maʻalahi loa a hoʻohana pinepine ʻia e like menā apo hōʻiliʻili.
Hoʻohana ʻia nā loulou hoʻohui e hoʻohui i nā ʻāpana o ke kaulahao i kahi hoʻopaʻa hopena a i ʻole ke apo hōʻiliʻili a hiki ke hana mechanical a i ʻole welded.
E like me nā ʻāpana lako hana ʻē aʻe, e mālama pono i nā kūlana ASME pili a me ka wehe ʻana mai nā pae lawelawe.
