Ngingakwazi Ukujoyina Izihlilingi Ezimbili Ndawonye ukuze Ngelule Ubude?

Ithimba labagebenga lilungisa ilifti. Umthwalo ungamamitha angu-15 ubude, kodwa kuphela isihlilingi esiyisicaba esitholakalayo singamafidi ayi-10. Umphathi udinga isihlilingi eside—futhi ngokushesha. Isilingo sokumane sihlanganise izihlilingi ezimbili ezimfishane cishe asinakuvinjwa.

Kodwa umphathi wokukhwabanisa uyazi kangcono. Ngokuya nge -OSHA 1910.184(c)(2) , noma kunini lapho kusetshenziswa noma isiphi isihlilingi, izihlilingi ngeke zifushaniswe ngamafindo noma amabhawodi noma ezinye izisetshenziswa zokuzenzela. I-ASME B30.9 ngokufanayo idinga ukuthi izihlilingi zingasonti, zifinyezwe, zinwetshwe, ziboshwe zibe amafindo, noma zihlanganiswe ngokufiphaza.

I-Lishenflex isineminyaka eminingi ikhiqiza izihlilingi eziyisicaba zokwenziwa, futhi ulwazi lwethu lwasensimini lubonisa ukuthi ukuxhunywa kwesihlilingi okungafanele kuyimbangela ehamba phambili yezigameko zokugetshengwa . Isenzo esilula sokuhlanganisa izihlilingi ezimbili ndawonye singanciphisa amandla ngo-50% noma ngaphezulu, sidale iphuzu lokuhluleka okuyinhlekelele ngaphansi komthwalo.

1. Kungani Ukujoyina Izihlilingi Ngqo Kuyingozi

Indlela ejwayeleke kakhulu yokuhlanganisa izihlilingi ezimbili iyifindo noma i- girth hitch (unyawo lwe-lark). Zombili izindlela zenza ukugoba okubukhali okugxilisa ukucindezeleka endaweni encane. Ngokokuhlola okubalulwe emphakathini okhuphukayo wase-UK, i-hitch ye-girth inganciphisa amandla e-sling cishe ngo- 50% . Ngisho nangaphansi kwe-Lifting Operations and Lifting Equipment Regulations (LOLER), ukunciphisa okungenani kungama -20% uma kwenziwa ngezihlilingi ezinobubanzi obulinganayo.

I-SpanSet ixwayisa ngokuthi noma yiluphi uhlobo lwesihlilingi—i-webbing sling, isihlilingi esiyindilinga, intambo yocingo, iketango—akumele iboshwe. Ukubopha ifindo kuzobangela ukuthi izingxenye ezifakwe amafindo zihlukane futhi zidale umonakalo, okungagcina kubangele ingozi ebulalayo.

1.2 'I-Pulley Effect' kanye nesenzo sokusika

Lapho ama-slings amabili ehlanganiswa futhi efakwa ngaphansi komthwalo, iphuzu lokuxhuma lisebenza njenge-pulley. Izihlilingi zinyakaza zodwa ngaphansi kokushuba okuphezulu, zidala ukungqubuzana nokusika okunganqamula imicu. I-SpanSet ikubeka ngokusobala ukuthi izihlilingi ezinamafindo zibangela ukuthi izingxenye zihlukaniselane, zidale umonakalo ongagcina ubangele ingozi ebulalayo. Yingakho amazinga e-OSHA kanye ne-ASME evimbela ukujoyina ngokufiphaza—umonakalo uyaqhubeka futhi ngokuvamile awubonakali kuze kube yilapho ukwehluleka.

1.3 Amazinga Emboni ayakwenqabela

Ngokwe- WAC 296-155-55825 , abaqashi akumele bafinyeze noma bandise izihlilingi ngokufiphaza noma ngokusonta. Lokhu kusebenza kuma-synthetic web slings. Ngaphansi kwe -ASME B30.9 , amafindo kunoma iyiphi ingxenye yesihlilingi ayizizathu zokususwa ngokushesha kusevisi. Lokhu kusho ukuthi isihlilingi esiboshiwe—ngisho nakanye—kumelwe silahlwe.

Umhlahlandlela wokuhlola we -Mazzella Companies ubala 'amafindo kunoma iyiphi ingxenye yesihlilingi' njengombandela odinga ukususwa enkonzweni, futhi uthi izihlilingi akufanele zisonte, ziboshwe zibe amafindo, noma zihlanganiswe ngokufiphaza. Ngokufanayo, i- Lifting Operations and Lifting Equipment Regulations (LOLER) iyakwenqabela ukuhlanganisa amafindo njengendlela yokufinyeza noma yokuhlanganisa izihlilingi.

2. Okushiwo Amazinga

3. Indlela Elungile Yokwelula Ubude Be-Sling

Uma izihlilingi ezimbili eziyisicaba kufanele zihlanganiswe ukuze kufinyelelwe ubude obudingekayo, okuwukuphela kwendlela ephephile ukusebenzisa ihadiwe yokuphakamisa okuzinikele.

3.1 Amaketanga

Amaketanga ayindlela evame kakhulu yokuhlanganisa ama-slings. Iso ngalinye lendwayimana linamathiselwe kwiphinikhodi ye-shackle noma umnsalo, okwenza iphoyinti lokuxhuma elilinganiselwe ngomthwalo. I-EN 1492-1 icacisa ukuthi izihlilingi zewebhu ezilukiwe eziyisicaba zingasetshenziswa nokufakwa, inqobo nje uma okokufaka kukalwe kahle futhi kuhambisana nesihlilingi.

Izidingo ezibalulekile uma usebenzisa amaketanga :

• I-Shackle WLL kufanele ilingane noma yeqe i-WLL yesihlilingi

• Usayizi wezintambo kufanele ulingane namehlo endwayimane ngaphandle kokubopha

• Iphinikhodi ye-shackle kufanele iqiniswe kahle futhi ivikeleke

3.2 Ama-Joker Hook kanye Nezixhumi Ezizinikele

I-SpanSet incoma i- Joker Hook njengendlela ephephile yokwelula ubude besihlilingi. I-Joker Hook isebenza njengesixhumi esixhumanisayo ukuze uhlanganise ubude bezihlilingi eziyindilinga noma izihlilingi zewebhu ndawonye, ​​okukuvumela ukuthi udale isihlilingi eside uma sidingeka. Inamandla okuphakamisa, amakhodi ombala, futhi ihambisana namazinga we-EN 1492.

3.3 Ukuxhumana Okuthambile (Uma Kuvunyelwe)

I-Liftex nabanye abakhiqizi bavumela ukuxhumana okuthambile kuphela lapho uxhumano lwenziwa ekulinganisweni kwehadiwe okukalwe ngokufanelekile—hhayi ukusling-to-sling ngokuqondile. Izinga lesiShayina le -GB/T 25854 ngokufanayo lidinga ukuthi zonke izingxenye zokuxhuma zilinganiselwe futhi zihambisane ne-WLL yesihlilingi, futhi zonke izingxenye kufanele zihlolwe ukuthi azigugile futhi zilimale ngaphambi kokusetshenziswa.

4. Kwenzekani Uma Usebenzisa I-Knotted Sling?

• Isihlilingi kufanele sicishwe : Ngokwe-ASME B30.9, amafindo adinga ukususwa enkonzweni.

• Izingcaphuno ze-OSHA : I-OSHA ivame ukucaphuna abaqashi ngokusebenzisa izihlilingi ezinamafindo. Okungenani esimweni esisodwa esibhaliwe, kwakhishwa i-catation ye-synthetic web sling eyayiboshwe ifindo.

• Ukunciphisa amandla : I-hitch ye-girth inciphisa amandla ngo-20-50%, kuye ngendlela yokuxhuma.

• Ingozi yokwehluleka kwenhlekelele : Ukungqubuzana nokusika efindo kungabangela ukwehluleka kungazelelwe ngaphansi komthwalo.

5. Izincomo Ezifingqiwe kanye Nezisebenzayo

Ukujoyina ama-slings amabili ayisicaba ngokushaya i-knotting noma i-girth hitching kuvinjelwe i-OSHA, ASME, EN 1492-1, kanye ne-LOLER . Lo mkhuba unciphisa amandla e-sling ngo-20-50%, udala umonakalo oqhubekayo osuka ekungqubuzaneni, futhi udalule opharetha engozini yokwehluleka okuyinhlekelele.

Okuthathwayo okubalulekile:

1. Ungalokothi ifindo noma i-girth-hitch slings ndawonye -kuvinjelwa izindinganiso eziningi futhi kunciphisa amandla kakhulu

2. Sebenzisa izingxenyekazi zekhompuyutha ezizinikele —amaketango, ama-Joker Hooks, noma ezinye izixhumi ezikala ukulayisha ziwukuphela kwezindlela eziphephile

3. Izilinganiso zokufanisa —zonke izingxenye zehadiwe ezixhumayo kufanele zibe ne-WLL elingana noma enkulu kune-WLL yesihlilingi

4. Hlola ukuxhumana - hlola ukuthi ihadiwe ilingana namehlo endwayimane futhi ayinakonakala

5. Qeqesha ithimba lakho - qinisekisa ukuthi bonke abaqaphi bayakwazi ukwenqatshelwa kokuxhumana okufakwe amafindo

I-Lishenflex ikhiqiza izihlilingi eziyisicaba ze-polyester ezisezingeni le-EN 1492-1 kanye ne-ASME B30.9, ezinomaka ogqamile onemibala egqamile kanye nokuthungwa okuthwala umthwalo. Futhi sinikezela ngezingxenyekazi zekhompuyutha zokukhwabanisa—okuhlanganisa amaketango nezixhumi—eziklanyelwe ukuxhumana okuphephile kwesihlilingi.

Uma udinga usizo lokukhetha ihadiwe yokuxhumana efanele yokusebenza kwakho kokuphakamisa—noma udinga usizo lokunquma indlela efanele yokwelula ubude besihlilingi—sicela uthumele i-imeyili ku- sales@lishenflex.com , futhi ithimba lethu lezobuchwepheshe lizohlinzeka ngokusekela komuntu ngamunye.
