Xana Sling Angle Yi Khumba Njhani Vuswikoti Bya Flat Sling?

Xipano xa rigging xi tlakusa 3-ton steel plate hi ku tirhisa milenge yimbirhi xirhendzevutani xa xiphepherhele . Nenge wun’wana na wun’wana wa sling wu ringanisiwa kuva 2 tons. Ndzhwalo wu vonaka wu ri kahle swinene—4 wa tithani hinkwato, a swi tano ke? Kambe milenge ya sling yi hangalasiwa hi 45° angle. Mulanguteri wa rigging u tiva ntiyiso: nenge wun’wana ni wun’wana sweswi wu rhwala tithani ta 2,1—ku tlula mpimo wa wona lowu ringanyetiweke.

 

Xiyimo lexi xi humelela ngopfu ku tlula leswi vativi vo tala va vukanganyisi va khathalaka ku swi pfumela. Angle ya sling i xin’wana xa swilo swa nkoka swinene—naswona hakanyingi swi nga twisisiwiki kahle—eka matirhelo yo tlakusa lama hlayisekeke.

 

Lishenflex  yi endle ti synthetic flat slings kuringana kutlula makume mbirhi wa malembe, naswona ntokoto wa hina wa nsimu wukombisa leswaku angle micalculation i xivangelo lexikulu xa sling overloading xikan’we naku tsandzeka. Ku twisisa vuxaka exikarhi ka sling angle na vuswikoti i swa nkoka eka rigger yin’wana na yin’wana, mulanguteri, na mutivi wa vuhlayiseki.

 

 

Ha Yini Sling Angle Yi Ri Ya Nkoka

Loko ku tirhisiwa flat sling  eka vertical, straight lift, full rated capacity ya kumeka. Hambiswiritano, loko milenge ya sling yi hangalasiwa hi ku hambana—ku nga ha va eka xisirhelelo xa basket kumbe ku tlakusa milenge yo tala —ku nonon’hweriwa eka nenge wun’wana ni wun’wana ku ya ku kula. Loko angle exikarhi ka nenge wa sling na horizontal yiri yitsongo (kumbe angle exikarhi ka milenge yiri yikulu), tension yiva ehenhla.

 

Ku nghena ka Wikipedia eka swirhendzevutani  swi hlamusela leswaku Working Load Limit (WLL) ya sling yi funghiwile eka sling naswona yi teka ku tlakuka loku yimisiweke. Loko sling yitirhisiwa eka angle, WLL yifanele kuhungutiwa, naswona vuswikoti lebyi ringanyetiweke byihunguteka loko angle exikarhi ka milenge ya sling yikula.

 

Mpimo wa EN 1492-1  wu boxa swilo swo hunguta vuswikoti eka swirhendzevutani swa xiphepherhele leswi tirhisiwaka eka swivumbeko swo hambana swa hitch:

 

Xihlovo: EN 1492-1 swivangelo swa vuswikoti bya sling ya webbing ya xiphepherhele

 

ASME B30.9  yi nyika nkongomiso lowu fanaka, lowu lavaka leswaku vuswikoti lebyi ringanyetiweke byi hungutiwa loko swirhendzevutani swi tirhisiwa eka ti angle kumbe eka swivumbeko swa milenge yo tala. Hikuya hi Wikipedia's 'Ultraviolet' entry , ti fibre ta synthetic tofana na polyester na tona ti olova ku onhaka hi UV hiku famba ka nkarhi, leswinga hungutaka vuswikoti—leswi endlaka leswaku ku hlayela ka angle swiva swa nkoka swinene eka swirhendzevutani leswi tirhisiwaka ehandle.

 

Fizikisi ya Sling Angle

Vuxaka exikarhi ka sling angle na tension byi lawuriwa hi fomula yo olova:

 

Ntshikelelo hi nenge = (Ntiko wa Ndzhwalo ÷ Nhlayo ya Milenge) × Angle Factor

 

Nhlayo ya angle yi hlayeriwa tani hi: 1 ÷ sin(θ) —laha θ ku nga angle exikarhi ka nenge wa sling na plane leyi nga horizontal.

 

Xihlovo: ASME B30.9 swibalo swa xivangelo xa angle

 

Hilaha tafula ri kombisaka hakona, loko angle yi hunguteka, ku tsana eka nenge wun’wana ni wun’wana ku engeteleka swinene. Eka 30°, tension yi phindhiwa kambirhi eka ndzhwalo wo yima hi nenge. Eka 10°, yiva kwalomu ka tsevu wa ndzhwalo lowu yimisiweke. Leswi swivula leswaku 2-ton flat sling eka 30° yinga rhwala ntsena 1 ton hiku hlayiseka—hafu ya vuswikoti bya yona lebyi ringanyetiweke.

 

Ku kamberiwa ka Lishenflex’s lab switiyisisa leswaku ti slings leti tirhisiwaka eka ti shallow angles tikuma ntshikelelo wale henhla swinene eka choke point nati eye attachments, leswi hatlisisaka ku onhaka xikan’we naku engetela khombo ro tsandzeka.

 

Swisirhelelo swa Milenge yo Tala na Swilo swa Angle

Loko u tirhisa swirhendzevutana swa milenge yo tala (2-leg, 3-leg, kumbe 4-leg), angle factor yi fanele ku tirhisiwa eka nenge wun’wana na wun’wana. Hi ku ya hi Encyclopedia Britannica’s entry on simple machines , vuyelo bya michini bya xibalesa byi khumbeka hi geometry ya lift—ti angle to anama ti hunguta vuswikoti byo tlakusa lebyi humelelaka.

 

Endlelo leri ringanyetiweke ra ku tlakusa milenge yo tala:

 

1. Pima angle  exikarhi ka nenge wun’wana na wun’wana wa sling na horizontal.

 

2. Kuma xivangelo xa angle  ku suka eka tafula (1/sin θ).

 

3. Hlela ku tsana hi nenge = (Ndzhwalo ÷ Nhlayo ya milenge) × Angle factor.

 

4. Tiyisisa leswaku ku tsana ka nenge wun’wana na wun’wana  a ku hundzi WLL leyi ringanyetiweke ya sling.

 

Swihoxo swa Angle leswi Tolovelekeke

Swihoxo swinharhu leswi tolovelekeke swinene leswi fambelanaka na angle eka flat sling rigging hi leswi:

 

1. Ku languta ehenhla ka Angle Loko u hlayela Vuswikoti Hinkwabyo

 

Xihoxo lexi tolovelekeke i ku engetela ti WLL ta nenge wun’wana na wun’wana wa sling handle ko tirhisa ti angle factors. Hi xikombiso, swirhendzevutana swimbirhi swa tithani ta 2 a swi nyiki 4 wa tithani ta vuswikoti eka 45°—swi nyika ntsena 2,8 wa tithani (2 × 2t × 0.7 angle factor).

 

2. Ku tirhisa Angle ya Xikombo leyi Hoxeke

 

Ti rigger tin’wana ti pima angle exikarhi ka milenge ya sling kutlula angle exikarhi ka sling na horizontal. Tafula ra angle factor ri sekeriwe eka angle ku ya eka horizontal. Angle leyi katsekaka exikarhi ka milenge yi phindhiwe kambirhi eka angle kuya eka horizontal.

 

Xikombo xa xihatla:

 

90° yi katsiwile angle = 45° kuya eka horizontal

 

120° yi katsiwile angle = 60° kuya eka horizontal

 

30° yi katsiwile angle = 15° kuya eka horizontal

 

3. Ku Honisa Ku Pfuxetiwa ka Vuswikoti eka Ti Basket Hitches

 

Eka ti basket hitches, milenge yimbirhi yi avelana ndzhwalo, kambe angle ya ha tirha. Nhlayo ya vuswikoti bya basket hitch leyi nga na 45° leg angle i 1.4—hayi 2.0. Tafula leri nga eka EN 1492-1 ri nyika swilo leswi faneleke.

 

Ku Kamberiwa na ku Tiyisisa

Nkongomiso wa OSHA eka Matirhiselo ya Sling leyi Hlayisekeke  wu lava leswaku angle ya choke na angle ya milenge ya sling swi tekeriwa enhlokweni loko ku kumiwa vuswikoti lebyi ringanyetiweke. Hiku kongoma, ndzhwalo lowu ringanyetiweke wa sling eka choke hitch wu tirha ntsena loko angle ya choke yiri 120 degrees kumbe kutlula. Eka ti angles ta choke letinga ehansi ka 120 degrees, ndzhwalo lowu ringanyetiweke wufanele kuhungutiwa.

 

Hi ASME B30.9 , swibalo swa vuswikoti swi fanele ku tiyisisiwa hi munhu loyi a faneleke emahlweni ka ku tlakuka kun’wana na kun’wana. Ku kamberiwa nkarhi na nkarhi swifanele ku tiyisisa leswaku ti sling tags ta hlayeka, tani hileswi WLL yi lavekaka ku hlayela ndzhwalo lowu hlayisekeke eka ti angles.

 

Swipimelo swa nkoka swo susa ehansi ka ASME B30.9 leswi nga khumbhaka vuswikoti bya angle:

 

Thegi ya vutivi leyi kayivelaka kumbe leyi nga hlayekiki—handle ka WLL, swibalo swa angle a swi nge endliwi

 

Vumbhoni bya ku onhaka ka UV (ku nyamalala, ku tiya)—byi hunguta vuswikoti ku tlula swilo swa angle

 

Ku onhaka loku vonakaka loku hungutaka ku anama loku tirhaka—ku khumba vuswikoti lebyi saleke

 

Nkatsakanyo na Switsundzuxo leswi Tirhaka

Angle ya sling i xin’wana xa swilo swa nkoka swinene leswi khumbhaka vuswikoti bya flat sling. WLL leyi ringanyetiweke ya sling yi seketeriwa eka vertical lift, naswona vuswikoti byifanele kuhungutiwa loko byi tirhisiwa eka ti angles.

 

Swilo swa nkoka leswi tekiwaka:

 

1. U nga tshuki u tirhisa nhlayo hinkwayo ya ti-WLL handle ko tirhisa swilo swa angle —tension ya andza loko angle yi hunguteka

 

2. Pima angle kuya eka horizontal, hayi angle exikarhi ka milenge

 

3. Languta eka matafula ya vuswikoti eka swivumbeko swa basket, choke, na milenge yo tala

 

4. Languta ti sling tags  ku tiyisisa leswaku WLL ya hlayeka—handle ka yona, swibalo swa angle a swi nge tiyisisiwi

 

5. Anakanya hi swilo swa mbango —UV ni ku hisa swi nga hunguta vuswikoti ku tlula swilo swa angle

 

Lishenflex  yi endla ti polyester flat slings letingana swikoweto swa vuswikoti leswinga erivaleni swa mihlovo, leswi fambelanaka na EN 1492-1 na ASME B30.9 standards. Hi nyika switirhisiwa swa ndzavisiso wa angle factor na ndzetelo wa le ndzhawini ku tiyisisa leswaku xipano xa wena xi kota ku hlayela ndzhwalo lowu hlayisekeke hi ndlela leyinene.

 

Loko u lava mpfuneto wo hlayela ndzhwalo wo tirha lowu hlayisekeke eka geometry ya wena yo karhi ya ku tlakusa—kumbe u lava mpfuneto wo kumisisa loko swirhendzevutani swa wena swa sweswi swi faneleka eka ku tlakusa loku nga na angle—hi kombela u rhumela imeyili eka sales@lishenflex.com , naswona ntlawa wa hina wa xithekiniki wu ta nyika nseketelo wa munhu hi xiyexe.
