Nigute Inguni ya Sling igira ingaruka mubushobozi bwa Fling Sling?

Itsinda ryibeshya rizamura isahani ya toni 3 ikoresheje amaguru abiri umugozi . Buri kaguru kanyerera kapimwe kuri toni 2. Umutwaro urasa neza mubushobozi-toni 4 zose, sibyo? Ariko amaguru ya shitingi akwirakwijwe kuri 45 °. Umugenzuzi wuburiganya azi ukuri: buri kaguru ubu gatwaye toni 2,1-karenze ubushobozi bwacyo.

 

Ibi bintu bibaho kenshi kuruta abanyamwuga benshi bariganya kubyemera. Inguni ya shitingi ni kimwe mu bintu bikomeye - kandi bikunze kutumvikana - mu bikorwa byo guterura umutekano.

 

Lishenflex  imaze imyaka isaga makumyabiri ikora ibihingwa ngengabihe, kandi uburambe mu murima bwerekana ko kubara nabi ari impamvu nyamukuru itera imitwaro iremereye no gutsindwa. Gusobanukirwa isano iri hagati ya sling angle nubushobozi nibyingenzi kuri buri rigger, umugenzuzi, ninzobere mumutekano.

 

 

Impamvu Kuringaniza Inguni

Iyo umugozi uringaniye  ukoreshwa muburyo buhagaritse, bugororotse, ubushobozi bwuzuye burahari. Ariko, uko amaguru ya shitingi akwirakwijwe - haba mu gatebo cyangwa kuzamura amaguru menshi - impagarara muri buri kaguru ziriyongera. Gutoya inguni hagati yamaguru yamaguru na horizontal (cyangwa nini nini hagati yamaguru), niko impagarara nyinshi.

 

Wikipedia yinjiye kumurongo  irasobanura ko Imipaka Yumurimo (WLL) yumurongo wa shitingi irangwa kumurongo kandi ifata lift ihagaritse. Iyo umugozi ukoreshejwe ku mfuruka, WLL igomba kugabanuka, kandi ubushobozi bwagenwe bugabanuka uko inguni iri hagati yamaguru ya shitingi yiyongera.

 

Ibipimo bya EN 1492-1  byerekana ibintu bigabanya ubushobozi kumirongo iringaniye ikoreshwa muburyo butandukanye:

 

Inkomoko: EN 1492-1 yibikoresho bya webbing sling ubushobozi ibintu

 

ASME B30.9  itanga ubuyobozi busa, busaba ko ubushobozi bwagabanijwe bwagabanywa mugihe imirongo ikoreshwa kumpande cyangwa muburyo bwinshi. Dukurikije ibyanditswe na Wikipedia 'Ultraviolet ', fibre synthique nka polyester nayo irashobora kwanduzwa na UV mugihe, ibyo bikaba bishobora kurushaho kugabanya ubushobozi - bigatuma kubara inguni birushaho kuba ingirakamaro kubice byakoreshejwe hanze.

 

Imiterere ya Sling Angle

Isano iri hagati ya sling angle and tension igengwa na formula yoroshye:

 

Impagarara ku kuguru = (Kuremerera Uburemere ÷ Umubare w'amaguru) Factor Inguni

 

Inguni yibarwa ibarwa nka: 1 ÷ icyaha (θ) —ahantu hose θ ni inguni hagati yamaguru yamaguru nindege itambitse.

 

Inkomoko: ASME B30.9 kubara ibintu bifatika

 

Nkuko imbonerahamwe ibigaragaza, uko inguni igabanuka, impagarara muri buri kuguru ziyongera cyane. Kuri 30 °, impagarara zikubye kabiri umutwaro uhagaritse ukuguru. Kuri 10 °, ni hafi inshuro esheshatu umutwaro uhagaze. Ibi bivuze ko toni 2 ya shitingi ya 30 ° ishobora gutwara gusa toni 1-kimwe cya kabiri cyubushobozi bwayo.

 

Igeragezwa rya laboratoire ya Lishenflex yemeza ko imigozi ikoreshwa ku mpande zidafite uburambe bugaragara cyane ku mpagarara zometse ku ijosi no ku jisho, kwihuta kwambara no kongera ibyago byo gutsindwa.

 

Amaguru menshi-Amaguru hamwe ninguni

Iyo ukoresheje imigeri myinshi (2-ukuguru, 3-ukuguru, cyangwa 4-ukuguru), ikintu kigomba gukoreshwa kuri buri kuguru. Nk’uko Encyclopedia Britannica yandika ku mashini zoroshye , ibyiza bya tekinike ya shitingi bigira ingaruka kuri geometrike ya lift - impande nini zigabanya ubushobozi bwo guterura neza.

 

Uburyo busabwa bwo guterura amaguru menshi:

 

1. Gupima inguni  hagati ya buri kaguru kanyerera na horizontal.

 

2. Menya ibintu bifatika  uhereye kumeza (1 / icyaha θ).

 

3. Kubara impagarara ku kuguru = (Umutwaro ÷ Umubare w'amaguru) factor Impamvu.

 

4. Menya neza ko ukuguru kwa buri kuguru  kutarenze WLL yagenwe.

 

Amakosa Rusange

Amakosa atatu akunze kugaragara cyane muburyo bugororotse ni:

 

1. Kwirengagiza Inguni Iyo Kubara Ubushobozi Bwuzuye

 

Ikosa risanzwe ni ukongera WLLs ya buri kaguru kanyerera udakoresheje ibintu bifatika. Kurugero, ibice bibiri bya toni 2 ntibitanga toni 4 zubushobozi kuri 45 ° - bitanga toni 2.8 gusa (2 × 2t × 0.7 inguni).

 

2. Gukoresha Inguni itari yo

 

Ruggers zimwe zipima inguni hagati yamaguru ya shitingi aho kuba inguni hagati ya shitingi na horizontal. Imbonerahamwe yibintu ishingiye ku mfuruka igana kuri horizontal. Inguni yashyizwemo hagati yamaguru ni inshuro ebyiri inguni kuri horizontal.

 

Byihuse:

 

90 ° yashyizwemo inguni = 45 ° kuri horizontal

 

120 ° yashyizwemo inguni = 60 ° kuri horizontal

 

30 ° yashyizwemo inguni = 15 ° kuri horizontal

 

3. Kwirengagiza Kugabanya Ubushobozi Mubiseke

 

Mubiseke, amaguru yombi asangira umutwaro, ariko inguni iracyakoreshwa. Ubushobozi bwibikoresho byigitebo gifite 45 ° inguni ni 1.4 - ntabwo ari 2.0. Imbonerahamwe muri EN 1492-1 itanga ibintu byukuri.

 

Kugenzura no Kugenzura

Amabwiriza ya OSHA ku Gukoresha Slinge Yizewe  arasaba ko harebwa inguni ya choke hamwe nu mfuruka yamaguru ya shitingi mugihe hagenwe ubushobozi. By'umwihariko, umutwaro wagenwe kuri shitingi muri choke urakurikizwa mugihe inguni ya choke ari dogere 120 cyangwa zirenga. Ku mfuruka ya choke iri munsi ya dogere 120, umutwaro wagenwe ugomba kugabanuka.

 

Kuri ASME B30.9 , kubara ubushobozi bigomba kugenzurwa numuntu ubishoboye mbere ya buri lift. Igenzura kenshi rigomba kugenzura ko ibirango bya sling byemewe, kuko WLL isabwa kubara imitwaro itekanye kuruhande.

 

Ibipimo byingenzi byo gukuraho munsi ya ASME B30.9 bishobora guhindura ubushobozi bwinguni:

 

Kubura cyangwa kutamenyekana biranga - udafite WLL, kubara inguni ntibishobora gukorwa

 

Ibimenyetso byangiza UV (gushira, gukomera) - bigabanya ubushobozi burenze ibintu bifatika

 

Ibyangiritse bigaragara bigabanya ubugari bukomeye - bigira ingaruka kubushobozi busigaye

 

Incamake n'ibyifuzo bifatika

Inguni ya shitingi ni kimwe mubintu bikomeye bigira ingaruka kubushobozi bwa shitingi. Urutonde rwa WLL rushingiye ku kuzamura guhagaritse, kandi ubushobozi bugomba kugabanuka iyo bikoreshejwe ku mfuruka.

 

Ibyingenzi byingenzi:

 

1. Ntukigere ukoresha igiteranyo cya WLL udakoresheje ibintu bifatika - impagarara ziyongera uko inguni igabanuka

 

2. Gupima inguni kuri horizontal, ntabwo ari inguni hagati yamaguru

 

3. Reba kumeza yubushobozi bwibiseke, kuniga, hamwe namaguru menshi

 

4. Kugenzura ibirango byerekana  ko WLL isomeka - bitabaye ibyo, kubara inguni ntibishobora kugenzurwa

 

5. Reba ibintu bidukikije -UV nubushyuhe birashobora kugabanya ubushobozi burenze ibintu bifatika

 

Lishenflex  ikora polyester iringaniye ifite ibimenyetso byerekana amabara asobanutse neza, yujuje ubuziranenge bwa EN 1492-1 na ASME B30.9. Dutanga ibikoresho bifatika hamwe namahugurwa kurubuga kugirango tumenye neza ko itsinda ryanyu rishobora kubara imitwaro itekanye neza.

 

Niba ukeneye ubufasha bwo kubara imizigo ikora neza kugirango uzamure geometrie yihariye - cyangwa ukeneye ubufasha bwo kumenya niba ibice byawe bikwiranye no kuzamura inguni - nyamuneka ohereza imeri kuri sales@lishenflex.com , hamwe nitsinda ryacu tekinike tuzatanga inkunga kumuntu umwe.
