Paʻa Paʻa: Hana ʻia ʻo Webbing, Ply Layers, a me ka hiki ke hoʻouka

Pono ka hui wili i ka maʻa hāpai no ka ukana maʻalahi—he kila i poni ʻia, kahi pahu mīkini pena ʻia, a i ʻole kahi papa kuʻi paʻa mua. Hele lākou i kahi maʻa palahalaha  no ka mea, ʻaʻole ia e ʻakaʻaka a pohō paha i ka ʻili ukana. Akā me nā koho he nui ma ka rack — nā laula like ʻole, nā helu ply like ʻole, nā hoʻonohonoho maka ʻokoʻa-ʻo wai ka mea kūpono no ka hana?

 

Ua hana ʻo Lishenflex  i nā maʻa palahalaha synthetic no ʻelua mau makahiki, a ʻo kekahi nīnau a mākou e lohe pinepine nei: Pehea e pili ai ke kūkulu ʻana i ka webbing i ka hiki ke hoʻouka? Aia ka pane ma ka hoʻomaopopo ʻana i ka pilina ma waena o nā mea, nā ʻāpana, a me ka laula—ua wehewehe ʻia ia mau mea a pau e EN 1492-1, ka maʻamau ʻEulopa no nā maʻa maʻa palahalaha.

 

Mea Hana Uwelewele: ʻO ke kumu o ka hana maʻa palahalaha

Hana ʻia nā maʻa palahalaha mai 100% kiʻekiʻe-tenacity synthetic fibers —ma ka polyester, polyamide (nylon), a i ʻole polypropylene. Hāʻawi kēlā me kēia mea i nā ʻano ʻokoʻa:

 

ʻO ka polyester ka mea i hoʻohana nui ʻia no nā maʻa palahalaha ma muli o kona  elongation haʻahaʻa - ʻoi aku ka liʻiliʻi ma mua o 3% hoʻonui i ka mana i helu ʻia - e hōʻoiaʻiʻo ana i ka mana paʻa i ka wā hāpai. Hāʻawi ia i ke kūpaʻa maikaʻi loa i ka makū, ka lepo, ka radiation UV, a me nā mea kemika he nui, e kūpono ana i nā kaiapuni o loko a me waho.

 

Wahi a FRT Manufacturing , hāʻawi ka polyester slings i kahi ʻoi aku ka ikaika-a-kaumaha ratio i hoʻohālikelike ʻia me nā nylon a i ʻole polypropylene nā mea ʻē aʻe a ʻaʻole i hoʻopilikia ʻia e ka wai kai, e hoʻolilo iā lākou i mea kūpono no ka hāpai ʻana i ke kai a me waho. ʻAʻole kūʻē ka Polyester i ka hapa nui o nā waikawa mineral a hana maikaʻi i nā kaiapuni me nā aila, nā ʻawaʻawa, a me nā alkalis.

 

No EN 1492-1, kūpono nā maʻa palahalaha i hana ʻia me ka polyester a me ka polyamide no ka hoʻohana ʻana a me ka mālama ʻana i nā mahana mai -40°C a 100°C , aʻo nā maʻa polypropylene i helu ʻia no -40°C a 80°C.

 

Nā Layer Ply: Pehea lākou e pili ai i ka hiki

ʻO ka Ply e pili ana i ka helu o nā ʻāpana webbing i hoʻohana ʻia i ka hana ʻana o ka maʻa. Hiki ke hana ʻia ka maʻa me ka hana hoʻokahi-ply, pālua-pā (duplex), a i ʻole multi-ply  (ʻekolu a quadruple) paha.

 

ʻO ka pilina ma waena o ka helu ply a me ka hiki ke maʻalahi: ʻo kēlā me kēia ply hou e pāpālua i ka hiki ke hoʻouka no ka laula pūnaewele like.

 

Hoʻomaopopo ʻo SpanSet  e hāʻawi ʻelua kā lākou mau maʻa pau ʻole 2-ply i ka hiki ke hāpai ʻia o nā maʻa 1-ply me ka laulā like. Ua wehewehe ʻia ka maʻa paʻa S1 o CERTEX Kelemānia ma ke ʻano he ' kāʻei hoʻokiʻekiʻe duplex' me 'nā ʻāpana kaula ʻelua,' i loaʻa i nā mana a hiki i 10 tons.

 

E like me ka hōʻike ʻana o ka China Chamber of Commerce  specifications, no ka laula i hāʻawi ʻia, hoʻonui ka WLL me ka helu o nā plies. No ka laʻana, loaʻa paha i kahi maʻa pā hoʻokahi 50 mm he WLL o 2 tons, aʻo kahi maʻa pālua pālua 50 mm hāʻawi i kahi mana 4-ton.

 

Laulā Uwelewele a me ka hiki ke hoʻouka

Ma lalo EN 1492-1 , hoʻopili pololei ʻia ka mana maʻa palahalaha me ka laula pūnaewele. Hōʻike ka maʻamau i ka hana ʻia ʻana o nā maʻa palahalaha i ulana ʻia ma ka laulā mai 25 mm a 450 mm.

 

ʻO ke kānāwai o ka ʻoihana i hoʻohana nui ʻia, i hoʻopaʻa ʻia e nā mea hana he nui, ʻo kēlā me kēia 25-30 mm o ka laulā webbing e hāʻawi i 1 ton o ka hiki ke hāpai pololei. .

 

ʻO CERTEX Kelemānia ka papaʻaina no EN 1492-1 polyester flat slings :

 

Puna: CERTEX Kelemānia, EN 1492-1 ʻikepili kaha

 

E like me ka hōʻike ʻana o ka papaʻaina, hoʻonui ʻia ka hiki ʻana o ka webbing ākea, akā pili pū ka pilina e ka hoʻonohonoho hitch . Hoʻemi ka choke hitch i ka WLL i ka 80% o ka hiki ke hāpai pololei (factor 0.8), aʻo ka hīnaʻi hīnaʻi e hoʻonui i ka mana ma 1.4 a 2.0 ma muli o ke kihi.

 

Hoʻopaʻa kala: ʻike hiki ke wikiwiki

Kauoha ʻo EN 1492-1 i kahi ʻōnaehana kala kala no nā maʻa paʻa, e hana wikiwiki a paʻa ʻole i ka ʻike ʻana ma nā wahi hana.

 

Puna: EN 1492-1 maʻamau kala-kala

 

Lawe ʻia kēlā me kēia maʻa i kahi lepili i humuhumu mau ʻia e hōʻike ana i ka WLL, ka helu ply, ka lōʻihi, ka lā hana, a me ka helu serial—pono no ka ʻike ʻana a me ka hoʻokō ʻana. E like me kā SpanSet i hoʻomaopopo ai, loaʻa i kā lākou maʻa he ' hōʻailona kala me ka leka hoʻokiʻekiʻe i humuhumu ʻia ma ka maʻa i hiki ʻole ke nalowale, ' hiki ke heluhelu ʻia ma lalo o nā ukana kaumaha a me nā kūlana lepo.

 

Nā hoʻonohonoho maʻa palahalaha

Loaʻa nā maʻa palahalaha ma nā ʻano hoʻonohonoho ma lalo o nā kūlana ASME B30.9 a me EN 1492-1:

 

Hoʻomaopopo ʻo Ace Industries  i ka maʻa maka a me ka maʻa 'maʻalahi loa' a he koho maikaʻi no nā kūlana hoʻokiʻekiʻe he nui, me ka maʻalahi o ka maka palahalaha e wehe a hoʻokomo ʻia i loko o nā wahi liʻiliʻi. Hoʻohui ʻo FRT Manufacturing e hāʻawi nā maʻa pau ʻole i ka wahi pili loa a e hōʻemi i ka pōʻino o ka ʻili.

 

Hōʻuluʻulu a me nā Manaʻo Hoʻomaʻamaʻa

ʻO ke kūkulu ʻia ʻana o ka maʻa paʻa —mea, nā ʻāpana, a me ka laula—e hoʻoholo pololei i kona hiki ke hoʻouka, ka lōʻihi, a me ke kūpono o ka noi. He mea nui ka hoʻomaopopo ʻana i kēia mau mea i ke koho ʻana i ka maʻa kūpono no kāu hana hāpai.

 

Nā mea nui e lawe ai:

 

ʻO nā mea waiwai —ʻo ka polyester ka koho maʻalahi loa no ka hāpai ʻana i ke kumu nui

 

ʻOi aku ka nui o nā pā = hiki ke kiʻekiʻe — hāʻawi ʻelua-pālua i ka WLL o ka pā hoʻokahi me ka laulā like

 

Nā lula laula— ma kahi o 1 tona no ka 25 mm o ka laula pūnaewele ma ka hoʻonohonoho hāpai pololei

 

Hoʻomaʻamaʻa nā code kala i ke koho ʻana— EN 1492-1 color-coding e hana koke i ka ʻike hiki

 

Hoʻopili ka hoʻonohonoho hitch i ka WLL— e ʻimi mau i nā papa ʻaina no ka choke a me ka hīnaʻi hiʻi

 

Hana ʻo Lishenflex  i nā maʻa paʻa polyester i nā maʻamau EN 1492-1, loaʻa i ka hoʻonohonoho hoʻokahi-ply, double-ply, a me multi-ply, me nā hōʻailona hiki ke hoʻopaʻa ʻia kala a me nā koho maka i hoʻoikaika ʻia. Loaʻa kā mākou huahana i nā laula mai 25 mm a 300 mm me nā WLL mai ka 1 ton a 10 tons.

 

Inā makemake ʻoe i ke kōkua no ke koho ʻana i ka maʻa maʻa palahalaha kūpono no kāu noi hoʻokiʻekiʻe kikoʻī—a i ʻole pono e kōkua i ka hoʻoholo ʻana i ka ply a me ka laula kūpono no kāu koi ukana—e ʻoluʻolu e hoʻouna i leka uila i sales@lishenflex.com , a e hāʻawi kā mākou hui loea i ke kākoʻo hoʻokahi.
