Uwuthatha nini umhlala-phantsi iilingi zokunyusela: Isikhokelo esibonakalayo sokusikwa, ukuqhawuka, kunye nokutshiswa kwemichiza

A isilingi sokuphakamisa  sitsalwa kwindawo yokugcina. Ibukeka ilungile-akukho manxeba acacileyo, akukho mpahla ebonakalayo. Abasebenzi abarhwebi bayisebenzisela ukunyuswa kwesiqhelo. Isilingi siyasilela. Umthwalo uyehla. Uphando lubonisa unobangela: umonakalo wangaphakathi owawungabonakali ngexesha lokutshekisha kwangaphambili.

Le meko idlala kwiindibano zocweyo kunye neendawo zokwakha minyaka le. Ngokutsho kwedatha yeshishini, ipesenti enkulu yokusilela kwisilingi kwenzeka kwizilingi ezibonakala ziluncedo kwiliso lenyama  . UKhuseleko eMsebenzini kunye noLawulo lwezeMpilo (OSHA)  igxininisa ukuba i-slings eyonakalisiweyo kufuneka isuswe kwinkonzo, kodwa umbuzo obalulekileyo ngulo: uyazi njani xa umonakalo unzima ngokwaneleyo ukuba uthathe umhlala-phantsi?

 

I-Lishenflex  sele isenza izilingi zokunyusa ezenziweyo iminyaka engaphezu kwamashumi amabini, kwaye idatha yethu yasendle ibonisa ukuba abaninzi abaqhankqalazi bayasokola ukwahlula phakathi kokunxiba kwezithambiso kunye nomonakalo obeka esichengeni ukhuseleko. Esi sikhokelo sinika isalathisi esibonakalayo kwiintlobo zomonakalo eziqhelekileyo kunye neendlela ezithile zomhlalaphantsi ezichazwe yi-ASME B30.9 kunye ne-OSHA imigaqo.

 

Ukusika kunye neenyembezi

Ukusika kunye neenyembezi ziphakathi kwezona ntlobo zomonakalo eziqhelekileyo kunye nezicacileyo. Nangona kunjalo, ayizizo zonke iinqumle ezifuna umhlala-phantsi ngokukhawuleza-ubunzulu, indawo, kunye nobukhulu bubonisa ukuba isilingi kufuneka silahlwe.

 

Iikhrayitheriya zomhlalaphantsi zokusikwa

 

Ngokuka ASME B30.9 , isilingi kufuneka sisuswe kwinkonzo xa:

 

• Ukusikwa, ukukrazula, okanye ama-snags aveza imisonto ephambili-wakuba umaleko ongaphandle okhuselayo uphazamisekile, imicu ethwele umthwalo iba sesichengeni.

• Imingxuma okanye iinyembezi kwi-webbing ezigqobhoza kubunzima obugcweleyo

• Nakuphi na ukusika okunciphisa ububanzi bewebhu ngesixa esibalulekileyo

 

NgokweSikhokelo se-OSHA ngokuSetyenziswa kwe-Sling ngokuKhuselekileyo, imingxuma, iinyembezi, ukusikwa, ukunxitywa kwe-abrasive, okanye i-snags  zidweliswe phakathi kweemeko ezifuna ukususwa ngokukhawuleza kwinkonzo. Iziko laseKhanada leMpilo kunye noKhuseleko lwezeMisebenzi (CCOHS) yongeza ukuba ukusika, ukulila, ukukrazula, okanye imingxuma kumzimba we-sling zibonakaliso ezibonakalayo zomonakalo ogunyazisa ukususwa.

 

Ukuchongwa okubonakalayo:

 

• Ukusikwa kancinci komphezulu - kuphela imicu engaphezulu echaphazelekayo; inokwamkeleka ukuba akukho ngundoqo oveziweyo

• Ukusikwa nzulu -ukungena ngaphaya kweeleya ezininzi okanye kuveze imicu engundoqo

• I-Edge cut-cut enciphisa ububanzi obusebenzayo be-webbing emphethweni

 

Inqaku elibalulekileyo:  Nokuba umphetho we-10% unqumle unokunciphisa umthamo we-sling nge-35%. Yiyo loo nto i-ASME B30.9 ifuna ukususwa xa nakuphi na ukusikwa kubeka esichengeni ububanzi okanye ulwakhiwo lwesilingi.

 

I-Abrasion kunye nokuNxitywa

Ukukrazula kwenzeka xa izilingi zirhuqelwa kwiindawo ezirhabaxa, zitsalwa kwiindawo ezimxinwa, okanye zisetyenziswa ngaphandle kwezikhuseli zekona kwimithwalo ebukhali. Ngokungafaniyo nokusikeka, i-abrasion ihlala ihamba kancinci kwaye inokungahoywa.

 

Iikhrayitheriya zokuThatha umhlalaphantsi kwi-Abrasion

 

Ngokwe ASME B30.9 , isilingi kufuneka sisuswe kwinkonzo xa:

 

• Ukunxitywa kwe-abrasive ngokugqithisileyo kukhoyo-impahla eveza imisonto engundoqo okanye inciphisa kakhulu indawo yesilingi.

• I-abrasion engaphezulu inxitywe kwi-webbing yangaphandle ukuya kumbindi wokuthwala umthwalo

• Ukunxiba okugxininiswe kwindawo enye-i-localized abrasion iyingozi ngakumbi kunokunxitywa komphezulu ofanayo

 

I-EN 1492-1  ixela ukuba izilingi zewebhu ezisicaba kufuneka zisuswe xa ukunxitywa kwe-abrasive konakalise i-webbing ukuya kwindawo apho ububanzi be-original buncitshisiwe okanye kophuke imicu.

 

Ukuchongwa okubonakalayo:

 

• Ukukhanya komphezulu we-fuzzing-okuqhelekileyo ekusetyenzisweni; eyamkelekileyo

• Iincam ezityumkileyo—zinokwamkeleka ukuba zincinane, kodwa zihlole rhoqo

• Iindawo ezigugileyo—ezibonisa imisonto yangaphakathi okanye imisonto; kufuneka abe umhlala phantsi

• Ifayibha engumgubo phakathi kwemisonto—ibonisa ukukrazuka okuhambele phambili

 

Idatha yelebhu ye- Lishenflex ibonisa ukuba izilingi ezisetyenzisiweyo ngaphandle kwezikhuseli zekona zinokulahlekelwa ukuya kuthi ga kwi-50% yamandla abo ngokuphakamisa okukodwa ngenxa ye-abrasion egxininisiweyo kwindawo yoqhagamshelwano. Izikhuseli ezikoneni azikhethi-zibalulekile kubomi obude.

 

Ukutshiswa kwemichiza kunye nomonakalo

Umonakalo wemichiza unokuba yenye yezona ntlobo ziyingozi zomonakalo we-sling kuba isoloko ingabonakali kwaye inokuchaphazela yonke i-sling's cross-section ngaxeshanye.

 

Iikhrayitheriya zomhlala-phantsi zokonakala kweMichiza

 

Ngokutsho kweCCOHS, i-nylon slings yonakaliswa yi-acids, ngelixa i-polyester slings yonakaliswa yi-alkalis. Xa kwenzeka umonakalo weekhemikhali, isakhiwo sefiber siphazamiseka, kaninzi ngaphandle kwesalathisi esibonakalayo.

 

Ngokwe ASME B30.9 , isilingi kufuneka sisuswe kwinkonzo xa:

 

• Ukutshisa i-Acid okanye i-caustic ikhona

• Ukutshintsha kombala okubonisa ukuba sesichengeni kweekhemikhali

• Iindawo ezinqabileyo okanye eziqinileyo ezibonisa ukuthotywa kwefiber

 

Isikhokelo sokhuseleko se-Liftex Slings silumkisa ukuba isilingi sichaneke kwi-asidi okanye kwimichiza ye-caustic kwaye ifayibha yonakaliswe, isilingi siba lukhuni kwaye sibe brittle, okukhokelela kumbala omdaka okanye omnyama. Ezi zilingi kufuneka zisuswe ngokukhawuleza kwinkonzo.

 

Ukuchongwa okubonakalayo:

• Ukuqina okanye ukuqaqanjelwa—ukonakala kwemichiza kwenza imicu iqine

• Ukonakala kwebala (umbala omdaka, omnyama, okanye ongaqhelekanga) —okudla ngokuba namabala okanye kwiindawo ezityhilekileyo

• Ukuqhawuka komphezulu okanye ukuxobula—kubonisa ukuwohloka okuhambele phambili

• Ukuqina okungaqondakaliyo kwiindawo ezingenakunxitywa

Ukonakala kobushushu kunye ne-Weld Splatter

Ukutshatyalaliswa kobushushu kuyingozi kakhulu kuba kunokusenza buthathaka isilingi ngaphandle kokutshintsha kwendawo ebonakalayo kude kube yimicu ibe yi-brittle.

 

Iikhrayitheriya zomhlala-phantsi zokonakaliswa kobushushu

 

Ngokwe-ASME B30.9 kunye ne-OSHA, isilingi kufuneka sisuswe kwinkonzo xa:

 

• Ubungqina bomonakalo wobushushu—ukunyibilika, ukutshisa, okanye ukugqabhuka

• I-Weld splatter eye yadibanisa kwi-webbing

• Iindawo ezinqabileyo okanye eziqinileyo ezibonisa ukuthotywa kwe-thermal

 

I-CCOHS ithi amaqondo obushushu angaphezu kwama-90°C (194°F) kwipolyester nenayiloni nangaphezulu kwe-80°C (176°F) kwipolypropylene anokubangela umonakalo osisigxina. I-OSHA idwelisa ngokukodwa ukunyibilika, ukutshaja, okanye i-weld splatter kuyo nayiphi na inxalenye yesilingi njengemeko yokususwa ngokukhawuleza kwinkonzo.

 

Ukuchongwa okubonakalayo:

 

• Iintsinga ezinyibilikisiweyo okanye ezidityanisiweyo—indawo yesilingi ibonakala imenyezekile okanye inyibilika

• Ukutsha okanye ukwenza mnyama—kusuka kwidangatye okanye i-weld splatter

• Amaqamza okanye amaqamza kwindawo yesilingi

• Ukuqina ngaphandle kokutshisa-ukuvela kobushushu ngaphantsi kwendawo yokunyibilika kusenokubangela ukuhla

 

Ukonakaliswa kweUV kunye nokuBulala

Ukukhanya kombala kudla ngokuba luphawu lokuqala olubonakalayo lokuthotywa kwe-UV-kwaye luphawu lokuba isilingi sisenokuba sele silahlekelwe ngamandla amakhulu.

Iikhrayitheriya zomhlala-phantsi kumonakalo we-UV

 

Ngokwe-ASME B30.9 kunye ne-WAC 296-155-55825 , isilingi kufuneka sisuswe kwinkonzo xa:

 

• Umbala ogqabhukileyo okanye ophelelweyo ukhona

• Ukwandiswa kokuqina kwempahla ye-sling

• Ukuqhawuka komphezulu kwiindawo eziqhele ukudibana nomthwalo

• Iindawo ezinqabileyo okanye eziqinileyo ezibonisa ukuthotywa kwefiber

 

IRigging Institute ilumkisa ngelithi izilingi ezingqukuva ezinebhatyi ezinombala okhanyayo zinokuphulukana ne-40 pesenti yamandla azo okugqibela kwisithuba seenyanga ezintandathu eziqhubekayo zokuvelelwa yi-UV. Ngokwesikhokelo seLiftex, umonakalo we-UV unokuchaphazela amandla ewebhu okwenziwa ngamaqondo ahlukeneyo ukusuka kokuncinci ukuya ekuthotyweni ngokupheleleyo.

 

Ukuchongwa okubonakalayo:

 

• Umbala ositheleyo—isilingi siphulukene nombala waso wangaphambili (ngokufuthi sibonakala sijiyile okanye simhlophe)

• Ukuqina okanye ukuqaqanjelwa—imicu eyonakaliswe yi-UV iba ngqongqo

• Ukuqhekeka komphezulu okanye ukujongwa—iintanda ezintle kumphezulu wesilingi

 

Ukuthunga kunye nokonakala kweSplice

Ukuthunga lelona candelo ligxininiswe kakhulu kwisilingi. Iziqwenga ezithwele umthwalo kunye namehlo zithwala umthwalo opheleleyo, kwaye umonakalo wokuthunga udla ngokuba sisalathisi sokuqala sokungaphumeleli okuzayo.

 

Iikhrayitheriya zomhlala-phantsi zomonakalo wokuthunga

 

Ngokwe ASME B30.9 , isilingi kufuneka sisuswe kwinkonzo xa:

 

• Ukuthungwa okwaphukileyo okanye okugugileyo kwiziqwenga ezithwele umthwalo

• Ukuthunga ukutsalwa ngaphandle -ukuthungwa kukwahlula kwi-webbing

• Ukuqhekeka okanye ukunxiba kakhulu kwii-seams ezithwele umthwalo

 

I-EN 1492-1 ichaza ukuba ukuthunga kufuneka kuhlolwe ngokubonakalayo umonakalo kwaye akufuneki kube nemithungo eyaphukileyo kwiindawo ezithwele umthwalo.

 

Ukuchongwa okubonakalayo:

 

• Umthungo owaphukileyo—umsonto omnye okanye ngaphezulu oqhawukileyo kwiliso okanye kwindawo yesplice

• Umthungo ogugileyo—umthungo uye wagqabhuka kwaye ubonakala ubhityile okanye ugugile

• Umthungo wokutsalela ngaphandle—ukuthunga kukwahlula kumzimba wesilingi

• Ukuthungwa okungalinganiyo okanye okugqwethekileyo-kusenokubonisa ukugcwala okanye ukwenziwa ngendlela engafanelekanga

 

Isishwankathelo kunye neeNgcebiso eziSebenzayo

Ukwazi ixesha lokurhola isilingi sokuphakamisa kubalulekile kukhuseleko emsebenzini. Umgaqo ongundoqo: xa uthandabuza, yisuse.

 

Uluhlu lokukhangela umhlala-phantsi ngoko nangoko:

 

Amanyathelo asebenzayo okuphumeza:

 

1. Ukuqhuba ukuhlolwa kwangaphambili kokusetyenziswa-ngaphambi kokuphakamisa konke, khangela umonakalo obonakalayo

2. Iziphumo zokuhlolwa kwamaxwebhu-gcina iirekhodi ngokweemfuno ze-ASME B30.9

3. Susa izilingi ezonakeleyo ngoko nangoko—ungaze 'ugcine' isilingi ukuze ulahlwe kamva

4. Tshabalalisa izilingi ezisele zisidla umhlala-phantsi—zisike okanye zonakalise inkangeleko yazo ukuze uthintele ukusetyenziswa kwakhona ngempazamo

5. Qeqesha iqela lakho-qinisekisa ukuba zonke iiriggers ziyakwazi ukuchonga iintlobo zomonakalo kunye neendlela zomhlalaphantsi

 

I-Lishenflex  ivelisa i-polyester yokuphakamisa izilingi ukuya kwi-EN 1492-1 kunye nemigangatho ye-ASME B30.9, kunye neempawu ezicacileyo ezinombala ocacileyo kunye nenkxaso yoqeqesho lokuhlola. Sigxininisa ukuba ukuhlolwa rhoqo kunye nokuthatha umhlala-phantsi ngexesha sisiseko sokuphakamisa ukhuseleko.
