ʻO ka wā e hoʻomaha ai i kahi maʻa hoʻokiʻekiʻe: alakaʻi ʻike no ka ʻoki ʻana, abrasion, a me ke ahi kino

A ka maʻa hāpai ʻia mai ka pā waihona.  huki ʻia Maikaʻi ke nānā aku—ʻaʻohe ʻoki ʻoki ʻia, ʻaʻohe ʻaʻahu ʻike ʻia. Hoʻohana ka poʻe hoʻokele liʻiliʻi no ka hāpai maʻamau. Hāʻule ka maʻa. Hāʻule ka ukana. Hōʻike ka hoʻokolokolo ʻana i ke kumu: ka pōʻino kūloko i ʻike ʻole ʻia i ka wā o ka hoʻohana mua ʻana.

Ke pāʻani nei kēia hiʻohiʻona i nā hale hana a me nā kahua kūkulu i kēlā me kēia makahiki. Wahi a ka ʻikepili ʻoihana, loaʻa ka hapa nui o nā maʻa hāʻule i nā maʻa i ʻike ʻia i hiki ke lawelawe ʻia i ka maka ʻōlohelohe  . ʻO ka ʻoihana palekana a me ke ola kino (OSHA)  ʻo ia ka manaʻo e wehe ʻia nā maʻa pohō mai ka lawelawe ʻana, akā ʻo ka nīnau koʻikoʻi: pehea ʻoe e ʻike ai i ka nui o ka pōʻino e hoʻomaha ai i kahi maʻa?

 

Ke hana nei ʻo Lishenflex  i nā maʻa hoʻokiʻekiʻe synthetic no ʻelua mau makahiki, a ke hōʻike nei kā mākou ʻikepili i ka nui o nā riggers e hakakā nei e hoʻokaʻawale i waena o nā lole nani a me nā pōʻino e hōʻemi i ka palekana. Hāʻawi kēia alakaʻi i kahi kuhikuhi ʻike no nā ʻano pōʻino maʻamau a me nā pae hoʻomaha kikoʻī i wehewehe ʻia e nā hoʻoponopono ASME B30.9 a me OSHA.

 

ʻOki a me nā waimaka

ʻO ka ʻoki a me ka waimaka kekahi o nā ʻano pōʻino maʻamau a maopopo. Eia naʻe, ʻaʻole pono nā ʻoki āpau e hoʻomaha koke - ʻo ka hohonu, ka wahi, a me ka paʻakikī e hoʻoholo inā pono e ʻoki ʻia ka maʻa.

 

Nā Koina Hoʻomaha no nā ʻoki

 

Wahi a ASME B30.9 , pono e wehe ʻia kahi maʻa mai ka lawelawe inā:

 

• Nā ʻoki, nā waimaka, a i ʻole nā ​​ʻāʻī e hōʻike ana i nā wili kumu - i ka wā e hoʻopilikia ʻia ai ka ʻaoʻao o waho o ka pale, hiki ke hoʻopōʻino ʻia nā kaula lawe ukana.

• ʻO nā lua a i ʻole nā ​​waimaka i loko o ka webbing e komo i loko o ka mānoanoa piha

• ʻO kēlā me kēia ʻoki e hōʻemi ana i ka laula o ka webbing me ka nui nui

 

Per OSHA's Guidance on Safe Sling Use, nā puka, nā waimaka, nā ʻoki, nā ʻaʻahu abrasive, a i ʻole nā ​​snags  i helu ʻia ma waena o nā kūlana e pono ai ke wehe koke ʻia mai ka lawelawe. Hoʻohui ka Canadian Center for Occupational Health and Safety (CCOHS) ʻo nā ʻoki, nā waimaka, nā ʻāʻī, a i ʻole nā ​​lua i loko o ke kino maʻa he mau hōʻailona ʻike ʻia o ka pōʻino e pono ke wehe ʻia.

 

ʻike maka:

 

• ʻOki liʻiliʻi o ka ʻili—ʻo nā fiber pāpaʻu wale nō i hoʻopili ʻia; hiki ke ʻae ʻia inā ʻaʻole i hōʻike ʻia ke kumu

• ʻOki hohonu — komo i loko o nā ʻāpana ʻāpana he nui a i ʻole e hōʻike i nā ʻili kumu

• ʻOki ʻaoʻao — ʻoki e hōʻemi ana i ka laulā pono o ka pūnaewele ma ka lihi

 

Manaʻo koʻikoʻi:  ʻO ka ʻoki ʻoki 10% hiki ke hōʻemi i ka mana maʻa ma 35%. ʻO ia ke kumu e pono ai ʻo ASME B30.9 e wehe i ka wā e ʻoki nui ʻia ai ka laulā a i ʻole ka hale o ka maʻa.

 

Abrasion and Wear

Hana ʻia ka abrasion ke kauo ʻia nā maʻa ma luna o nā ʻili ʻōpala, huki ʻia ma nā wahi haiki, a i ʻole hoʻohana ʻia me ka ʻole o nā mea pale kihi ma nā ukana ʻoi. ʻAʻole e like me nā ʻokiʻoki, pinepine ka abrasion a hiki ke nānā ʻia.

 

Nā Koina Hoʻomaha no ka Abrasion

 

Ma ka ASME B30.9 , pono e wehe ʻia kahi maʻa mai ka lawelawe ʻana inā:

 

• Loaʻa ka ʻaʻahu abrasive nui loa—ʻaʻahu e hōʻike ana i nā wili kumu a i ʻole e hōʻemi nui i ka ʻāpana kea o ka maʻa.

• Ua pau ka abrasion o ka ili ma o ka webbing o waho a hiki i ke kumu lawe haawe

• ʻOi aku ka pōʻino o ka abrasion kūloko ma mua o ka ʻaʻahu o ka ʻili

 

Hōʻike ʻo EN 1492-1  e pono e wehe ʻia nā maʻa webbing flat i ka wā i hōʻino ʻia ai ka ʻaʻahu abrasive i ka webbing a hiki i kahi i hōʻemi ʻia ai ka laulā kumu a i ʻole nahā nā fibers.

 

ʻike maka:

 

• Māmā ka ʻili o ka ʻili — maʻamau mai ka hoʻohana ʻana; ʻae ʻia

• Nā ʻaoʻao haʻihaʻi - hiki ke ʻae ʻia inā ʻuʻuku, akā e nānā mau

• Nā wahi i ʻāhuehue —e hōʻike ana i nā ʻili o loko a i ʻole nā ​​wili kumu; pono e hoomaha

• ʻO ka pulupulu pulupulu ma waena o nā kaula —e hōʻike ana i ka abrasion holomua

 

Lishenflex i nā maʻa i hoʻohana ʻole ʻia me ka pale ʻole o ke kihi hiki ke nalowale a hiki i ka 50% o ko lākou ikaika i ka hoʻokiʻekiʻe hoʻokahi ma muli o ka hoʻopaʻa ʻana i ka abrasion ma ka wahi pili. Hōʻike ka ʻikepili lab o ʻAʻole koho nā mea pale kihi - pono lākou no ka lōʻihi o ka maʻa.

 

Puhi Kemika a Poino

ʻO ka pōʻino kemika kekahi o nā ʻano pōʻino ʻino loa o ka maʻa ma muli o ka ʻike ʻole ʻia a hiki ke hoʻopilikia i ka ʻāpana kea holoʻokoʻa o ka maʻa i ka manawa like.

 

Nā Koina Hoʻomaha no ka Poino Kemika

 

Wahi a CCOHS, ua hōʻino ʻia nā maʻa nylon e nā waikawa, aʻo nā maʻa polyester e hōʻino ʻia e ka alkali. Ke loaʻa ka pōʻino kemika, hoʻopilikia ʻia ka hana fiber, pinepine me ka ʻike ʻole ʻia o ka ʻili.

 

Ma ka ASME B30.9 , pono e wehe ʻia kahi maʻa mai ka lawelawe ʻana inā:

 

• Loaʻa ka ʻakika a i ʻole ke ahi

• Hōʻike ʻia ka wehe ʻana i nā kemika

• ʻO nā wahi palupalu a ʻoʻoleʻa paha e hōʻike ana i ka hōʻino ʻana o ka fiber

 

Hoʻomaopopo ke alakaʻi palekana ʻo Liftex Slings inā e ʻike ʻia ka maʻa i ka waika a i ʻole nā ​​​​kemika caustic a pohō ka fiber, lilo ka maʻa i ʻoʻoleʻa a palupalu, e hopena i ka ʻeleʻele a ʻeleʻele paha. Pono e wehe koke ʻia kēia mau maʻa mai ka lawelawe ʻana.

 

ʻike maka:

• Manaʻo ʻoʻoleʻa a palupalu paha - ʻo ka pōʻino kemika e paʻa ai nā fiber

• Hoʻololi (ʻeleʻele, ʻeleʻele, a i ʻole ka waihoʻoluʻu ʻē aʻe) - ʻaʻahu pinepine a i ʻole ma nā wahi i ʻike ʻia

• ʻO ka ʻili ʻana a i ʻole ka ʻili ʻana o ka ʻili - hōʻike i ka hoʻohaʻahaʻa kiʻekiʻe

• ʻO ka ʻoʻoleʻa i wehewehe ʻole ʻia ma nā wahi i hiki ʻole ke ʻaʻahu

Poino Wela a me Weld Splatter

ʻOi aku ka pōʻino o ka wela no ka mea hiki iā ia ke hoʻonāwaliwali i ka maʻa me ka ʻike ʻole ʻia o ka hoʻololi ʻana o ka ʻili a hiki i ka wā e haʻihaʻi ai nā ʻili.

 

Nā Koina Hoʻomaha no ka Poino Wela

 

No ka ASME B30.9 a me ka OSHA, pono e wehe ʻia kahi maʻa mai ka lawelawe ʻana inā:

 

• ʻO nā hōʻike o ka pōʻino o ka wela - ka hoʻoheheʻe, ka ʻā, a i ʻole ka pohū

• Weld splatter i hui pū ʻia me ka webbing

• ʻO nā wahi palupalu a ʻoʻoleʻa paha e hōʻike ana i ka hoʻohaʻahaʻa wela

 

Wahi a ka CCOHS, hiki i ka wela ma luna o 90°C (194°F) no ka polyester a me ka nylon a ma luna o 80°C (176°F) no ka polypropylene hiki ke hōʻeha mau. Hoʻopuka pololei ʻo OSHA i ka hoʻoheheʻe ʻana, ka ʻā, a i ʻole ka weld splatter ma kekahi ʻāpana o ka maʻa ma ke ʻano he kūlana no ka wehe koke ʻana mai ka lawelawe.

 

ʻike maka:

 

• ʻO nā fiber i hoʻoheheʻe ʻia a i hoʻohui ʻia paha - ʻike ʻia ka ʻili o ka maʻa he aniani a heheʻe paha

• ʻAna a ʻeleʻele paha —mai ka lapalapa ahi pololei a i ʻole ka wiliwili ʻana

• Phū — nā ʻōpū a i ʻole nā ​​ʻōhū ma ka ʻili o ka maʻa

• ʻO ka ʻoʻoleʻa me ka ʻeha ʻole - hiki ke hoʻohaʻahaʻa i ka wela ma lalo o kahi heheʻe

 

Poino a me ka Nalo o UV

ʻO ka mae ʻana o ka waihoʻoluʻu ʻo ia ka hōʻailona mua i ʻike ʻia o ka hoʻohaʻahaʻa ʻana o UV-a he hōʻailona ia ua nalowale paha ka ikaika nui o ka maʻa.

Nā Koina Hoʻomaha no ka Poino UV

 

Ma ka ASME B30.9 a me WAC 296-155-55825, pono e wehe ʻia kahi maʻa mai ka lawelawe ʻana inā:

 

• Loaʻa ka waihoʻoluʻu ʻeleʻele a mae

• Hoʻonui ʻia ka ʻoʻoleʻa o ka mea maʻa

• ʻO ka abrasion o ka ʻili ma nā wahi i pili ʻole i ka ukana

• ʻO nā wahi palupalu a ʻoʻoleʻa paha e hōʻike ana i ka hōʻino ʻana o ka fiber

 

Hoʻomaopopo ka Rigging Institute e hiki i nā maʻa pōʻai me nā ʻaʻahu ʻulaʻula ke lilo a hiki i ka 40 pakeneka o ko lākou ikaika hope loa i loko o ʻeono mahina o ka hoʻomau mau ʻana i ka UV. Wahi a ke alakaʻi ʻo Liftex, hiki i ka pōʻino o UV ke hoʻopilikia i ka ikaika o ka webbing synthetic i nā pae like ʻole mai ka liʻiliʻi a hiki i ka hōʻino ʻia.

 

ʻike maka:

 

• Ka waihoʻoluʻu—ua nalowale ka maʻa i kona waihoʻoluʻu kumu (e ʻike pinepine ʻia he bleach a keʻokeʻo paha)

• Manaʻo ʻoʻoleʻa a palupalu paha — ʻoʻoleʻa nā fiber i pohō ʻia e ka UV

• Māhā ʻili a nānā paha — nā māwae maikaʻi ma ka ʻili o ka maʻa

 

Ka humuhumu a me ka Poino Hoopaa

ʻO ka humuhumu ka mea koʻikoʻi loa o ka maʻa. ʻO nā haʻahaʻa haʻahaʻa haʻahaʻa a me nā maka e lawe i ka ukana piha, a ʻo ke kuʻi ʻana i ka pōʻino ʻo ia ka hōʻailona mua o ka hiki ʻole.

 

Koina no ka hoomaha no ka poino humuhumu

 

Ma ka ASME B30.9 , pono e wehe ʻia kahi maʻa mai ka lawelawe ʻana inā:

 

• ʻO ka humuhumu ʻana i haki ʻia a ʻeha paha i loko o nā mea hoʻopaʻa ukana

• humuhumu huki-waho —e kaawale ana ka humuhumu mai ka webbing

• Māhā a ʻaʻahu ʻino paha i nā hili ʻana i ka ukana

 

Hōʻike ʻo EN 1492-1 e nānā pono ʻia ka humuhumu ʻana no ka pōʻino a ʻaʻole pono e haki nā humuhumu ma nā wahi e lawe ana i ka ukana.

 

ʻike maka:

 

• Nā humuhumu haki — hoʻokahi a ʻoi aʻe paha nā kaula i haki ʻia ma ka maka a i ʻole ka ʻāpana splice

• ʻO ka humuhumu ʻino — ua ʻeha ka humuhumu ʻana a ʻike ʻia ka lahilahi a ʻeleʻele paha

• Huki-huki humuhumu —e kaawale ana ka humuhumu mai ke kino maa

• ʻO ka humuhumu like ʻole a i ʻole ka humuhumu ʻino—e hōʻike ana paha i ke kaumaha nui a i ʻole ka hana pono ʻole
