Ungayiyeka nini i-Lifting Slings: Umhlahlandlela Obonakalayo Wokusikwa, Ukuhuzuka, Nokushiswa Kwamakhemikhali

A isihlilingi sokuphakamisa  sikhishwa endaweni yokubeka. Kubukeka kukuhle-akukho ukusikeka okusobala, akukho ukugqokwa okubonakalayo. Iqembu labaqophi liyisebenzisela ukuphakamisa okujwayelekile. Isihlilingi siyehluleka. Umthwalo uyehla. Uphenyo luveza imbangela: umonakalo wangaphakathi obungabonakali ngesikhathi sokuhlolwa kwangaphambi kokusetshenziswa.

Lesi simo sidlala kuma-workshops nasezindaweni zokwakha njalo ngonyaka. Ngokwemininingwane yemboni, amaphesenti amakhulu okuhluleka kwezihlilingi kwenzeka ezindwayimaneni ezibonakala ziwusizo emehlweni enyama  . I-Occupational Safety and Health Administration (I-OSHA)  igcizelela ukuthi ama-slings awonakele kufanele asuswe enkonzweni, kodwa umbuzo obalulekile uwukuthi: wazi kanjani ukuthi umonakalo unzima ngokwanele ukuhoxisa isihlilingi?

 

I-Lishenflex  isineminyaka engaphezu kwamashumi amabili ikhiqiza izihlilingi zokwenziwa zokuphakamisa, futhi idatha yethu yasensimini ibonisa ukuthi ama-rigger amaningi akuthola kunzima ukuhlukanisa phakathi kokugqokwa kwezimonyo nomonakalo obeka ukuphepha engozini. Lo mhlahlandlela uhlinzeka ngereferensi ebonakalayo yezinhlobo zomonakalo ezivame kakhulu kanye nemibandela ethile yokuthatha umhlalaphansi echazwe yimithetho ye-ASME B30.9 kanye ne-OSHA.

 

Ukusikwa Nezinyembezi

Ukusikeka nezinyembezi kuphakathi kwezinhlobo zomonakalo ezivame kakhulu nezisobala. Kodwa-ke, akuwona wonke ama-cut cut adinga ukuhoxiswa ngokushesha—ukujula, indawo, kanye nobukhulu obunquma ukuthi isihlilingi kufanele silahlwe yini.

 

Imibandela Yokuthatha Umhlalaphansi Yokusikwa

 

Ngokuya nge -ASME B30.9 , isihlilingi kufanele sisuswe kusevisi lapho:

 

• Ukusikeka, izinyembezi, noma izihibe eziveza izintambo eziwumgogodla—uma ungqimba olungaphandle oluyisivikelo lusengozini, imicu ethwala umthwalo iba sengozini.

• Izimbobo noma izinyembezi kuwebhu ezingena phakathi kogqinsi olugcwele

• Noma yikuphi ukusika okunciphisa ububanzi bewebhu ngenani elibalulekile

 

Ngokwesiqondiso Se-OSHA Sokusetshenziswa Kwe-Safe Sling, izimbobo, izinyembezi, ukusikeka, ukuguga, noma ama-snags  afakwe ohlwini phakathi kwemibandela edinga ukususwa ngokushesha kusevisi . I-Canadian Centre for Occupational Health and Safety (CCOHS) yengeza ukuthi ukusikeka, izinyembezi, izimbobo, noma izimbobo emzimbeni we-sling kuyizimpawu ezibonakalayo zomonakalo ogunyaza ukususwa.

 

Ukuhlonza okubonakalayo:

 

• Ukusikwa okuncane kwendawo—kuthinteka imicu yangaphandle kuphela; ingamukeleka uma kungekho umongo oveziwe

• Ukujula -kungena ngezingqimba eziningi noma kuveza imicu ewumgogodla

• Ukusika kwe-Edge -ukusika okunciphisa ububanzi obusebenzayo bewebhu emaphethelweni

 

Inothi elibalulekile:  Ngisho nokusikwa konqenqema ngo-10% kungehlisa umthamo we-sling ngo-35%. Yingakho i-ASME B30.9 idinga ukususwa lapho noma yikuphi ukusika kuphazamisa ngokuphawulekayo ububanzi noma isakhiwo sesihlilingi.

 

I-Abrasion kanye Nokugqoka

Ukuhuzuka kwenzeka lapho ama-slings ehudulwa ezindaweni ezimahhadlahhadla, edonsa ezindaweni eziwumngcingo, noma esetshenziswa ngaphandle kwezivikeli zamakhona emithwalweni ebukhali. Ngokungafani nokusikeka, ukuhuzuka kuvame ukuhamba kancane futhi kunganganakwa.

 

Imibandela Yokuthatha Umhlalaphansi Ye-Abrasion

 

Ngokwe- ASME B30.9 , isihlilingi kufanele sikhishwe enkonzweni lapho:

 

• Kukhona ukuguga okweqile—okugqokwa okuveza izintambo ezibalulekile noma okunciphisa ingxenye enqamulayo yesihlilingi

• I-surface abrasion igugile kuwebhu yangaphandle kuya kumongo othwala umthwalo

• Ukugqokwa kugxile endaweni eyodwa—umhuzuko wasendaweni uyingozi kakhulu kunokugqoka endaweni efanayo

 

I-EN 1492-1  icacisa ukuthi izihlilingi zewebhu eziyisicaba kufanele zisuswe lapho ukuguga kulimaza iwebhu kuze kube yilapho ububanzi bangempela buncishiswa noma kuphuka imicu.

 

Ukuhlonza okubonakalayo:

 

• Ukufiphaza okukhanyayo ebusweni—okuvamile ekusetshenzisweni; eyamukelekayo

• Imiphetho ephukile—ingamukeleka uma incane, kodwa yihlole njalo

• Izindawo ezigugile—eziveza izinti zangaphakathi noma izintambo eziwumgogodla; kumele athathe umhlalaphansi

• I-fiber eyimpuphu phakathi kwemicu—ibonisa ukuhuzuka okuthuthukile

 

Idatha yelebhu ye- Lishenflex ibonisa ukuthi izihlilingi ezisetshenziswa ngaphandle kwezivikeli zamakhona zingalahlekelwa kufika ku-50% wamandla azo ekuphakamiseni okukodwa ngenxa yokuhuzuka okugxilile endaweni yokuxhumana. Izivikeli zasemakhoneni azikhethi—zibalulekile ukuze umuntu aphile isikhathi eside.

 

Ukushiswa Kwamakhemikhali Nokulimala

Ukulimala kwamakhemikhali kungaba olunye lwezinhlobo eziyingozi kakhulu zomonakalo wesihlilingi ngoba ngokuvamile awubonakali futhi ungathinta yonke ingxenye yesihlilingi kanyekanye.

 

Imibandela Yokuthatha Umhlalaphansi Yokulimala Kwekhemikhali

 

Ngokusho kwe-CCOHS, izihlilingi zenayiloni zonakaliswa ama-asidi, kuyilapho izihlilingi ze-polyester zonakala ngama-alkali. Uma kwenzeka umonakalo wamakhemikhali, isakhiwo se-fiber siyathinteka, ngokuvamile ngaphandle kwenkomba ebonakalayo ebonakalayo.

 

Ngokwe- ASME B30.9 , isihlilingi kufanele sikhishwe enkonzweni lapho:

 

• Ukusha kwe-Acid noma i-caustic kukhona

• Ukushintsha umbala okubonisa ukuchayeka kwamakhemikhali

• Izindawo eziqinile noma eziqinile ezibonisa ukuwohloka kwe-fiber

 

Umhlahlandlela wokuphepha we-Liftex Slings uxwayisa ngokuthi uma isihlilingi sichayeka ku-asidi noma kumakhemikhali e-caustic futhi ifayibha yonakaliswa, isihlilingi siba lukhuni futhi sibe brittle, okuholela ekushintsheni kombala onsundu noma okumnyama . Lezi zihlilingi kufanele zisuswe ngokushesha emsebenzini.

 

Ukuhlonza okubonakalayo:

• Ukuqina noma ukuhwamuka—ukulimala kwamakhemikhali kwenza imicu iqine

• Ukushintsha umbala (umbala onsundu, omnyama, noma ongajwayelekile)—ngokuvamile kuba nezimagqabhagqabha noma ezindaweni ezichayeke kuzo

• Ukucweba noma ukuxebuka—kubonisa ukuwohloka okuthuthukile

• Ukuqina okungaqondakali ezindaweni ezingagqoki

Ukulimala Kokushisa kanye ne-Weld Splatter

Ukulimala kokushisa kuyingozi kakhulu ngoba kungenza buthaka isihlilingi ngaphandle kokushintsha kwendawo ebonakalayo kuze kube yilapho imicu iba brittle.

 

Imibandela Yokuthatha Umhlalaphansi Yokulimala Kokushisa

 

Ngokwe-ASME B30.9 kanye ne-OSHA, isihlilingi kufanele sisuswe enkonzweni lapho:

 

• Ubufakazi bokulimala kokushisa—ukuncibilika, ukusha, noma amabhamuza

• I-Weld splatter ehlangene ne-webbing

• Izindawo eziqinile noma eziqinile ezibonisa ukuwohloka kokushisa

 

I-CCOHS ithi amazinga okushisa angaphezu kuka-90°C (194°F) e-polyester nenayiloni nangaphezulu kuka-80°C (176°F) we-polypropylene angabangela umonakalo unomphela. I-OSHA ibala ngokuqondile ukuncibilika, ukushaja, noma i-weld splatter kunoma iyiphi ingxenye yesihlilingi njengesimo sokususwa ngokushesha kusevisi.

 

Ukuhlonza okubonakalayo:

 

• Imicu encibilikile noma ehlanganisiwe—ingaphezulu lendwayimane libonakala licwebezelisiwe noma lincibilikile

• Ukushaja noma ukwenza mnyama—kusuka elangabini eliqondile noma i-weld splatter

• Amabhamuza - amabhamuza noma amabhamuza endaweni yesihlilingi

• Ukuqina ngaphandle kokusha—ukushisa ngaphansi kwendawo encibilikayo kusengabangela ukuwohloka

 

Ukulimala kwe-UV nokufiphala

Ukufiphala kombala ngokuvamile kuyinkomba yokuqala ebonakalayo yokuwohloka kwe-UV—futhi kuwuphawu lokuthi isihlilingi kungenzeka sesiphelelwe amandla abalulekile.

Imibandela Yokuthatha Umhlalaphansi Yokulimala Kwe-UV

 

Ngokwe-ASME B30.9 kanye ne-WAC 296-155-55825 , isihlilingi kufanele sisuswe kusevisi lapho:

 

• Umbala omhlophe noma ofiphele ukhona

• Ukukhula kokuqina kwempahla ye-sling

• Ukuhuzuka ebusweni ezindaweni ngokuvamile ezingahlangani nomthwalo

• Izindawo eziqinile noma eziqinile ezibonisa ukuwohloka kwe-fiber

 

I-Rigging Institute ixwayisa ngokuthi izihlilingi eziyindilinga ezinamajakhethi anombala okhanyayo zingalahlekelwa amandla afika kwangu-40 ekhulwini phakathi nenkathi yezinyanga eziyisithupha zokuchayeka kwe-UV. Ngokusho komhlahlandlela we-Liftex, ukulimala kwe-UV kungathinta amandla ewebhu okwenziwa ngamazinga ahlukahlukene ukusuka kokuncane kuye kokuwohloka okuphelele.

 

Ukuhlonza okubonakalayo:

 

• Umbala ofiphele—isihlilingi silahlekelwe umbala waso (ngokuvamile sibonakala simhlophe noma simhlophe)

• Ukuqina noma ukuhwamuka—imicu eyonakaliswe yi-UV iba lukhuni

• Ukuqhekeka komhlaba noma ukuhlola—imifantu emihle endaweni yesihlilingi

 

Ukuthunga kanye nokulimala kwe-Splice

Ukuthunga kuyingxenye egcizelelwe kakhulu yesihlilingi. Izingxenye ezithwala imithwalo namehlo zithwala umthwalo ogcwele, futhi ukulimala kokuthunga ngokuvamile kuyinkomba yokuqala yokwehluleka okuseduze.

 

Imibandela Yokuthatha Umhlalaphansi Yokulimala Kokuthungwa

 

Ngokwe- ASME B30.9 , isihlilingi kufanele sikhishwe enkonzweni lapho:

 

• Ukuthunga okuphukile noma okugugile ezincekwini ezithwala umthwalo

• Ukuthunga ukudonsa—ukuthunga kuyahlukana nolwembu

• Ukuqhekeka noma ukuguga okunzima kuma-seams athwala umthwalo

 

I-EN 1492-1 icacisa ukuthi ukuthunga kufanele kuhlolwe ngokubona umonakalo futhi akufanele kube nezitishi eziphukile ezindaweni ezithwala umthwalo.

 

Ukuhlonza okubonakalayo:

 

• Izithungo eziphukile—umcu owodwa noma ngaphezulu ogqashuke esweni noma endaweni yokuhlanganisa

• Ukuthungwa okugugile—umthungo usuqhumile futhi ubonakala uzacile noma usugugile

• Ukuthunga ukudonsa—ukuthunga kuyahlukana nomzimba wendwayimane

• Ukuthunga okungalingani noma okuhlanekezelwe—kungase kubonise ukugcwala noma ukukhiqizwa okungafanele

 

Izincomo Ezifingqiwe Nezisebenzayo

Ukwazi ukuthi ungayiyeka nini i-lifting sling kubalulekile ekuphepheni kwendawo yokusebenza. Umgomo oyinhloko: uma ungabaza, yisuse.

 

Uhlu lokuhlola lokuthatha umhlalaphansi ngokushesha:

 

Izenzo ezingokoqobo okufanele zenziwe:

 

1. Yenza ukuhlola ngaphambi kokusetshenziswa—ngaphambi kwayo yonke i-lift, hlola umonakalo obonakalayo

2. Okutholwe kokuhlolwa kwedokhumenti—gcina amarekhodi ngokwezidingo ze-ASME B30.9

3. Susa izihlilingi ezilimele ngokushesha—ungalokothi 'ugcine' isihlilingi ukuze usilahle kamuva

4. Bhubhisa izihlilingi esezithathe umhlalaphansi—zisike noma zingcolise ukuze ugweme ukuphinda zisetshenziswe ngengozi

5. Qeqesha ithimba lakho—qinisekisa ukuthi zonke iziqili ziyakwazi ukubona izinhlobo zomonakalo kanye nemibandela yokuthatha umhlalaphansi

 

I-Lishenflex  ikhiqiza izihlilingi zokuphakamisa i-polyester ezilinganisweni ze-EN 1492-1 kanye ne-ASME B30.9, ezinomaka ogqamile onemibala egqamile nokusekelwa kokuqeqeshwa kokuhlola. Sigcizelela ukuthi ukuhlolwa okuvamile kanye nokuthatha umhlalaphansi ngesikhathi kuyisisekelo sokuphakamisa ukuphepha.
