Hiki iaʻu ke hui pū me ʻelua mau maʻa palahalaha e hoʻonui i ka lōʻihi?

Ke hoʻomākaukau nei kahi hui ligging i kahi hāpai. He 15 kapuaʻi ka lōʻihi o ka ukana, ʻo ia wale nō ʻO ka maʻa paʻa i loaʻa he 10 kapuaʻi. Pono ka luna hoʻomalu i ka maʻa lōʻihi—a wikiwiki hoʻi. ʻO ka hoʻowalewale ʻana e hoʻohui i ʻelua maʻa pōkole ʻoi aku ka hiki ʻole ke pale.

Akā ʻoi aku ka ʻike o ka luna hoʻokele. Wahi a OSHA 1910.184(c)(2) , ke hoʻohana ʻia kekahi maʻa, ʻaʻole e hoʻopōkole ʻia nā maʻa me nā puʻupuʻu a i ʻole nā ​​bolts a i ʻole nā ​​​​mea hana ʻē aʻe. ʻO ka ASME B30.9 ke koi like ʻole ʻaʻole e wili ʻia nā maʻa, e hoʻopōkole ʻia, e hoʻolōʻihi ʻia, e hoʻopaʻa ʻia i loko o nā puʻupuʻu, a i ʻole e hui pū ʻia me ka wili.

ʻo Lishenflex i nā maʻa maʻa synthetic no nā makahiki he mau makahiki, a ke hōʻike nei kā mākou ʻike kula ʻo Ua hana nā pilina maʻa kūpono ʻole ke kumu nui o nā hanana rigging . ʻO ka hana maʻalahi o ka hoʻopaʻa ʻana i nā maʻa ʻelua hiki ke hōʻemi i ka ikaika ma 50% a ʻoi aku paha, e hana ana i kahi pōʻino pōʻino ma lalo o ka ukana.

1. No ke aha e pilikia ai ka hui ʻana i nā maʻa

1.1 Nā Naki a me nā ʻAi ʻAi—E hoemi i ka ikaika

ʻO ke ʻano maʻamau o ka hoʻohui ʻana i ʻelua maʻa, ʻo ia ka puʻupuʻu a i ʻole ka hitch girth (ka wāwae lark). Hoʻokumu ʻia nā ʻano ʻelua i nā piko ʻoi e kālele ana i ke koʻikoʻi ma kahi wahi liʻiliʻi. Wahi a ka hoʻāʻo ʻana i hōʻike ʻia ma ke kaiāulu piʻi ʻana o UK, hiki i kahi hitch girth ke hōʻemi i ka ikaika o ka maʻa ma kahi o 50% . ʻOiai ma lalo o nā Lifting Operations and Lifting Equipment Regulations (LOLER), ʻo ka emi ʻana he 20% ka liʻiliʻi ke hana ʻia me nā maʻa o ke anawaena like.

Hoʻomaopopo ʻo SpanSet ʻaʻole pono e hoʻopaʻa ʻia kēlā me kēia ʻano maʻa—maʻa pūnaewele, maʻa poepoe, kaula uwea, kaulahao. ʻO ka hoʻopaʻa ʻana i kahi puʻupuʻu e ʻoki ʻia nā ʻāpana i hoʻopaʻa ʻia i kekahi i kekahi a pōʻino, hiki ke hopena i kahi pōʻino make.

1.2 ʻO ka 'Pulley Effect' a me ka hana ʻoki

Ke hoʻohui ʻia nā maʻa ʻelua a kau ʻia ma lalo o ka haʻawe, hana ka wahi hoʻohui me he pulley. Ke neʻe nei nā maʻa i kekahi i kekahi ma lalo o ka haʻalulu kiʻekiʻe, e hana ana i ka friction a me ka hana ʻoki e hiki ai ke ʻoki i nā fibers. Hōʻike pololei ʻo SpanSet i nā maʻa wili e ʻoki ʻia nā ʻāpana i kekahi i kekahi, e hana ana i ka pōʻino i hiki ke hopena i kahi pōʻino make. ʻO ia ke kumu i pāpā ai nā kūlana OSHA a me ASME i ka hoʻohui ʻana me ka hoʻopaʻa ʻana—e holomua ana ka pōʻino a ʻike pinepine ʻole ʻia a hiki i ka hiki ʻole.

1.3 Ka Papa Hana Hana

Ma ka WAC 296-155-55825 , ʻaʻole pono nā mea hana e hoʻopōkole a hoʻolōʻihi paha i nā maʻa ma ka wili a wili paha. Pili kēia i nā maʻa pūnaewele synthetic. Ma lalo o ka ASME B30.9 , he kumu no ka wehe koke ʻia ʻana mai o ka lawelawe. ʻO ia ke ʻano o ka maʻa i hoʻopaʻa ʻia - ʻoiai hoʻokahi wale nō - pono e ʻoki ʻia.

ʻO ke alakaʻi nānā ʻana o nā ʻoihana ʻo Mazzella e papa inoa i nā 'nots ma kekahi ʻāpana o ka maʻa' ma ke ʻano he kūlana e pono ai ke wehe ʻia mai ka lawelawe ʻana, a ʻōlelo hou aʻe ʻaʻole e wili ʻia nā maʻa, nakinaki ʻia i loko o nā puʻupuʻu, a i ʻole e hui pū ʻia me ka wili. Pēlā nō, pāpā ʻia ka Lifting Operations and Lifting Equipment Regulations (LOLER) i ka hoʻopaʻa ʻana ma ke ʻano he ʻano pōkole a hoʻohui ʻana i nā maʻa.

2. He aha ka ʻōlelo a nā Kūlana

3. ʻO ke ala kūpono e hoʻonui ai i ka lōʻihi o ka maʻa

Inā pono e hoʻohui ʻia nā maʻa palahalaha ʻelua no ka loaʻa ʻana o ka lōʻihi i makemake ʻia, ʻo ke ala palekana wale nō ka hoʻohana ʻana i ka lako hoʻolaʻa.

3.1 Na kaulahao

ʻO ka shackles ke ala maʻamau no ka hoʻohui ʻana i nā maʻa. Hoʻopili ʻia nā maka o kēlā me kēia maʻa i ka pine shackle a i ʻole ke kakaka, e hana ana i kahi wahi hoʻopili i helu ʻia. Hōʻike ʻo EN 1492-1 e hiki ke hoʻohana ʻia nā maʻa pūnaewele i ulana ʻia me nā mea pono, inā e helu pono ʻia nā mea pono a kūpono me ka maʻa.

ʻO nā pono nui i ka hoʻohana ʻana i nā shackles :

• Pono ʻo Shackle WLL e like a ʻoi aku paha ma mua o ka WLL o ka maʻa

• Pono ka nui o ka shackle i nā maka maʻa me ka nakinaki ʻole

• Pono e hoʻopaʻa pono ʻia ka pine shackle a paʻa

3.2 ʻO Joker Hooks a me nā mea hoʻohui i hoʻolaʻa ʻia

Manaʻo ʻo SpanSet i ka Joker Hook ma ke ʻano he palekana palekana no ka hoʻonui ʻana i ka lōʻihi o ka maʻa. Hoʻohana ʻia ka Joker Hook ma ke ʻano he mea hoʻohui e hoʻohui i ʻelua mau lōʻihi o nā maʻa poepoe a i ʻole nā ​​maʻa webbing, e ʻae iā ʻoe e hana i kahi maʻa lōʻihi inā pono. Loaʻa iā ia ka hiki ke hoʻokiʻekiʻe, nā code kala, a hoʻokō me nā kūlana EN 1492.

3.3 Hoʻohui ʻoluʻolu (Ke ʻae ʻia)

Liftex a me nā mea hana ʻē aʻe ʻAe ʻo i nā pilina palupalu wale nō ke hana ʻia ka hoʻopili ʻana i kahi lako lako pono i helu ʻia-ʻaʻole pololei ka maʻa-i-maʻa. ʻO ka maʻamau Kina GB/T 25854 ke koi like ʻia e helu ʻia nā mea hoʻopili āpau a kūpono me ka WLL o ka maʻa, a pono e nānā ʻia nā ʻāpana āpau no ka ʻaʻahu a me ka pōʻino ma mua o ka hoʻohana ʻana.

4. He aha ka hopena inā hoʻohana ʻoe i kahi maʻa wili?

• Pono e ʻoki ʻia ka maʻa : No ka ASME B30.9, pono e wehe ʻia nā knots mai ka lawelawe ʻana.

• Nā ʻōlelo aʻoaʻo OSHA : Hoʻopuka pinepine ʻo OSHA i nā mea hana no ka hoʻohana ʻana i nā maʻa wili. I loko o hoʻokahi hihia i kākau ʻia, ua hoʻopuka ʻia kahi ʻōlelo no ka maʻa pūnaewele synthetic i hoʻopaʻa ʻia i kahi puʻupuʻu.

• Ka ho'ēmi ikaika : Hoʻemi ka hitch girth i ka ikaika e 20-50%, ma muli o ke ʻano pili.

• Hiki i ka pōʻino pōʻino : ʻO ke kuʻekuʻe a me ka hana ʻoki ʻana ma ka puʻupuʻu hiki ke hoʻopōʻino koke ma lalo o ka ukana.

5. Hōʻuluʻulu a me nā Manaʻo Hoʻomaʻamaʻa

ka hui ʻana i ʻelua maʻa palahalaha ma ka hoʻopaʻa ʻana a i ʻole ke kāʻei ʻAʻole pāpā ʻia e OSHA, ASME, EN 1492-1, a me LOLER . Hoʻemi ka hoʻomaʻamaʻa i ka ikaika o ka maʻa ma 20-50%, hana i ka pōʻino holomua mai ka friction, a hōʻike i nā mea hana i ka pōʻino pōʻino.

Nā mea nui e lawe ai:

1. Mai hoʻopaʻa a hoʻopaʻa i nā maʻa - pāpā ʻia e nā maʻamau he nui a hoʻemi nui i ka ikaika.

2. E hoʻohana i ka lako lako — shackles, Joker Hooks, a i ʻole nā ​​​​mea hoʻohui i helu ʻia i ka ukana ʻo ia wale nō nā ala palekana

3. Nā helu hoʻohālikelike — pono e loaʻa ka WLL like a ʻoi aku paha ma mua o ka WLL o ka maʻa.

4. E nānā i nā pilina —e nānā i ka lako pono i nā maka maʻa a ʻaʻohe pōʻino

5. E hoʻomaʻamaʻa i kāu hui - e hōʻoia i ka ʻike ʻana o nā riggers a pau i ka pāpā ʻana i nā pilina wili

Hana ʻo Lishenflex i nā maʻa palahalaha polyester i nā maʻamau EN 1492-1 a me ASME B30.9, me nā hōʻailona hiki ke hoʻopaʻa ʻia i ka kala a me ka humuhumu ukana. Hāʻawi pū mākou i nā lako hoʻopaʻa liʻiliʻi - me nā kaulahao a me nā mea hoʻohui - i hoʻolālā ʻia no nā pilina maʻa palekana.

Inā makemake ʻoe i ke kōkua no ke koho ʻana i ka lako pili pono no kāu mau hana hāpai ʻana—a i ʻole makemake i ke kōkua e hoʻoholo i ke ala kūpono no ka hoʻonui ʻana i ka lōʻihi o ka maʻa—e ʻoluʻolu e hoʻouna i leka uila i sales@lishenflex.com , a e hāʻawi kā mākou hui loea i ke kākoʻo hoʻokahi.
