Kodi Ndingajowine Masamba Awiri A Flat Pamodzi Kuti Nditalikitse Utali?

Ogwira ntchito yonyamula zida akukonzekera chokwera. Katunduyo ndi 15 mapazi kutalika, koma yekha gulaye lathyathyathya likupezeka ndi 10 mapazi. Woyang'anira amafunikira gulaye yayitali - komanso mwachangu. Chiyeso chongolumikiza gulaye tiwiri tating'ono tating'ono sitingakane.

Koma woyang'anira wowongolera amadziwa bwino. Malinga ndi OSHA 1910.184(c)(2) , nthawi iliyonse gulaye ikagwiritsidwa ntchito, gulaye sidzafupikitsidwa ndi mfundo kapena mabawuti kapena zida zina zongosintha. ASME B30.9 mofananamo imafuna kuti gulaye zisapiringidwe, kufupikitsidwa, kutalikitsa, kumanga mfundo, kapena kulumikizidwa ndi mfundo.

Lishenflex yakhala ikupanga ma slings opangidwa ndi lathyathyathya kwazaka zambiri, ndipo zomwe takumana nazo m'munda zikuwonetsa kuti kulumikizana kolakwika ndi gulaye ndizomwe zimayambitsa zochitika zakuba . Kuchita kosavuta kumangiriza ma gulaye awiri palimodzi kumatha kuchepetsa mphamvu ndi 50% kapena kupitilira apo, ndikupanga malo olephereka owopsa.

1. Chifukwa Chimene Kujowina Slings Mwachindunji Ndi Koopsa

1.1 Ma Knots ndi Girth Hitches-Kuchepetsa Kwambiri Mphamvu

Njira yodziwika kwambiri yolumikizira ma gulaye awiri ndi mfundo kapena girth hitch (phazi la lark). Njira zonsezi zimapanga mipiringidzo yakuthwa yomwe imayika kupsinjika pagawo laling'ono. Malinga ndi kuyezetsa komwe kunachitika ku UK, kugunda kwa girth kumatha kuchepetsa mphamvu ya gulaye pafupifupi 50% . Ngakhale pansi pa Lifting Operations and Lifting Equipment Regulations (LOLER), kuchepetsako ndi osachepera 20% pamene achita ndi slings ofanana awiri.

SpanSet imachenjeza kuti gulaye yamtundu uliwonse, gulaye, gulaye yozungulira, chingwe cha waya, unyolo, siyenera kukhala ndi mfundo. Kumanga mfundo kumapangitsa kuti ziwalo zomangira zidukane ndi kuwononga, zomwe pamapeto pake zingayambitse ngozi yoopsa.

1.2 'Pulley Effect' ndi Ntchito Yodula

Pamene zingwe ziwiri zilumikizidwa ndikuyikidwa pansi pa katundu, malo olumikizira amakhala ngati pulley. Ma gulaye amayenda molimbana wina ndi mzake chifukwa cha kukanikizana kwambiri, kumapangitsa kukangana ndi kudulana komwe kumatha kudula ulusi. SpanSet imanena mosapita m'mbali kuti ma gulayeti opangidwa ndi knoted amachititsa kuti ziwalozo zidulidwe, zomwe zimapangitsa kuwonongeka komwe kumatha kubweretsa ngozi yowopsa. Ichi ndichifukwa chake miyezo ya OSHA ndi ASME imaletsa kujowina ndikumangirira - kuwonongeka kumapita patsogolo ndipo nthawi zambiri sikuwoneka mpaka kulephera.

1.3 Miyezo Yamakampani Imaletsa

Pa WAC 296-155-55825 , olemba anzawo ntchito sayenera kufupikitsa kapena kutalikitsa gulaye poluka kapena kupindika. Izi zimagwiranso ntchito pazitsulo zopangira ukonde makamaka. Pansi pa ASME B30.9 , mfundo mu gawo lililonse la gulaye ndi chifukwa chochotsa ntchito nthawi yomweyo. Izi zikutanthauza kuti gulaye yomwe yamangidwa mfundo, ngakhale kamodzi, iyenera kuthyoledwa.

Bukhu loyendera la Mazzella Companies limatchula 'mfundo mu gawo lililonse la gulaye' monga momwe zimafunikira kuchotsedwa pa ntchito, ndipo limanenanso kuti gulaye sayenera kupindika, kumanga mfundo, kapena kulumikiza mfundo. Momwemonso, Lifting Operations and Lifting Equipment Regulations (LOLER) imaletsa knotting ngati njira yofupikitsa kapena kujowina gulaye.

2. Zomwe Miyezo Ikunena

3. Njira Yoyenera Yowonjezerera Utali wa Sling

Ngati gulayeni ziwiri zafulati ziyenera kulumikizidwa kuti zikwaniritse kutalika kofunikira, njira yokhayo yotetezeka ndiyo kugwiritsa ntchito zida zonyamulira zodzipereka.

3.1 Makatani

Ma shackles ndi njira yodziwika kwambiri yolumikizira ma slings. Diso la gulaye lililonse limamangiriridwa ku pini ya shackle kapena uta, ndikupanga malo olumikizirana ndi katundu. TS EN 1492-1 ma slings oluka athyathyathya atha kugwiritsidwa ntchito ndi zomangira, malinga ngati zoyikazo zidavoteredwa bwino komanso zogwirizana ndi gulaye.

Zofunikira zazikulu mukamagwiritsa ntchito maunyolo :

• Shackle WLL iyenera kufanana kapena kupitirira WLL ya gulaye

• Kukula kwa shackle kuyenera kukwanirana ndi maso a legeni popanda kumanga

• Pini ya shackle iyenera kumangidwa bwino ndikutetezedwa

3.2 Ma Joker Hooks ndi Zolumikizira Zodzipereka

SpanSet imalimbikitsa Joker Hook ngati njira yotetezeka yotalikitsira kutalika kwa gulaye. Joker Hook imagwira ntchito ngati cholumikizira cholumikizira kuti mulumikizane ndi mizere iwiri yozungulira yozungulira kapena gulaye limodzi, kukulolani kuti mupange gulaye yayitali ikafunika. Ili ndi mphamvu yokweza, ma code amtundu, ndipo imagwirizana ndi EN 1492 miyezo.

3.3 Malumikizidwe Ofewa (Pamene Aloledwa)

Liftex ndi opanga ena amalola kulumikizana kofewa pokhapokha ngati kulumikizidwa kwapangidwa ndi zida zoyezera moyenera-osati molunjika ku gulaye. Muyezo waku China wa GB/T 25854 mofananamo umafuna kuti zigawo zonse zolumikizira zivoteredwe ndi zogwirizana ndi gulaye's WLL, ndipo mbali zonse ziyenera kuyang'aniridwa kuti zawonongeka ndi kuwonongeka musanagwiritse ntchito.

4. Kodi Chimachitika N'chiyani Ngati Mugwiritsa Ntchito Sling Yopangidwa ndi Knotted?

• gulaye iyenera kuchotsedwa : Pa ASME B30.9, mfundo zimafunika kuchotsedwa ntchito.

• Zolemba za OSHA : OSHA nthawi zonse imatchula olemba anzawo ntchito kuti agwiritse ntchito ma slings okhala ndi mfundo. Pachochitika chimodzi cholembedwa, mawu adaperekedwa a gulaye yapaintaneti yomwe idamangidwa mfundo.

• Kuchepetsa mphamvu : Kugunda kwa girth kumachepetsa mphamvu ndi 20-50%, kutengera njira yolumikizira.

• Chiwopsezo cholephereka kwambiri : Kukangana ndi kudula pa mfundo kungayambitse kulephera kwadzidzidzi pansi pa katundu.

5. Mwachidule ndi Malangizo Othandiza

Kujowina awiri ma gulayeti ophwanyika pomenya kapena kumenyetsa girth ndikoletsedwa ndi OSHA, ASME, EN 1492-1, ndi LOLER . Mchitidwewu umachepetsa mphamvu ya gulaye ndi 20-50%, umapanga kuwonongeka pang'onopang'ono chifukwa cha kukangana, ndikuyika ogwiritsa ntchito pachiwopsezo cholephera.

Zofunikira zazikulu:

1. Palibe mfundo kapena girth-hitch slings palimodzi - ndizoletsedwa ndi miyezo yambiri ndipo zimachepetsa mphamvu kwambiri

2. Gwiritsani ntchito zida zodzipatulira - maunyolo, Joker Hooks, kapena zolumikizira zina zolemetsa ndizo njira zotetezeka zokha

3. Machesi - zida zonse zolumikizira ziyenera kukhala ndi WLL yofanana kapena yokulirapo kuposa WLL ya gulaye.

4. Yang'anani zolumikizira - onetsetsani kuti zida zolumikizirana zikugwirizana ndi maso a gulaye ndipo sizikuwonongeka

5. Phunzitsani gulu lanu - onetsetsani kuti onse oyendetsa galimoto akudziwa zoletsa kulumikizana ndi mfundo

Lishenflex imapanga ma poliester flat slings ku miyezo ya EN 1492-1 ndi ASME B30.9, yokhala ndi zolembera zowoneka bwino zamitundu komanso zomata zonyamula katundu. Timaperekanso zida zopangira zida - kuphatikiza maunyolo ndi zolumikizira - zopangidwira kulumikizana kotetezeka kwa gulaye.

Ngati mukufuna thandizo posankha zida zolumikizira zoyenera zonyamulira—kapena mukufuna thandizo kuti mudziwe njira yoyenera yotalikitsira kutalika kwa gulaye—chonde tumizani imelo kwa sales@lishenflex.com , ndipo gulu lathu laukadaulo lidzapereka chithandizo chamunthu payekha.
