Ngingakwazi Ukusebenzisa I-Flat Sling Ekucushweni Kwe-Choke Hitch?

Ithimba labagebhuli lidinga ukuphakamisa umthwalo oyisilinda—ipayipi lensimbi, ikholomu kakhonkolo, noma inqwaba ye-rebar. I isihlilingi esiyisicaba  abasithatha endaweni yokubeka ubude obufanele nomthamo. Kodwa umthwalo awunawo amaphuzu okunamathiselwe achaziwe. Isilingi sisonga isihlilingi nxazonke zomthwalo, sidlulise iso elilodwa kwelinye, futhi siyicinene siqine. Lokhu kuyi-hitch yokuminyanisa-futhi kungaba yisixazululo esisebenzayo sokukhwabanisa, kodwa kuphela uma kwenziwa ngendlela efanele.

 

I-Lishenflex  isineminyaka engaphezu kwamashumi amabili ikhiqiza izihlilingi zokwenziwa eziyisicaba, futhi ulwazi lwethu lwasensimini lubonisa ukuthi ama-coke hitches aphakathi kokucushwa kwesihlilingi okuvame ukusetshenziswa kabi. I-choke hitch ibonakala ilula, kodwa ukusebenza kwayo okuphephile kuncike ekuqondeni ukuncishiswa kwamandla, i-angle yokuklinywa efanele, nesimo sokusling. Ngokusho kwedatha yemboni  evela kubakhiqizi bezihlilingi abathobela i-EN 1492-1, umthamo we-choke hitch factor ngu-0.8—okusho ukuthi isihlilingi esilinganiselwe ngethani elingu-1 ekuphakameni okuqondile kungathwala ngokuphephile kuphela u-800 kg lapho kuginqika .

 

Iyini i-Choke Hitch?

I-choke hitch iwukucushwa kwe-rigging lapho isihlilingi sisonga umthwalo, futhi ingxenye eyodwa yesihlilingi idlula ngeso elihlukile noma elifanele. Umthwalo ube usuphakanyiswa, okwenza isihlilingi siqine nxazonke zomthwalo. Lokhu kudala umphumela we-cinching  ovikela umthwalo futhi uvimbele ukushelela .

 

Njengoba kuchazwe ku- OSHA's Guide on Safe Sling Use , i-choker hitch ifanele imithwalo okunzima ukuyibhalansisa noma ukuyivikela ngokuphakamisa okuqondile okuqondile . I-choker hitch ibamba umthwalo ngokuphepha ngokuwuqinisa. Kodwa-ke, i-OSHA ixwayisa ngokusobala ukuthi lapho uminyanisa, indawo yokuklinya kufanele ibe emzimbeni wendwayimane kuphela, ungalokothi ube ku-splice noma ofanele.

 

I  -Rigging Institute  iphawula ukuthi i-choke hitch ingenye yezinto ezintathu eziyinhloko zokugawula izihlilingi, ezihambisana nama-vertical and basket hitch, futhi ngokuvamile isetshenziswa uma umthwalo ungenazo izindawo zokunamathisela ezifanele.

 

Ukwehliswa kwamandla ku-Choke Hitch

Isici esibaluleke kakhulu ekusetshenzisweni kwe-choke hitch ukunciphisa umthamo. Umkhawulo womthwalo wokusebenza olinganiselwe we-sling uphezulu kakhulu ekudonseni okuqondile okuqondile. Uma isetshenziswa ekuvimbeni, umthamo uyancipha kakhulu.

 

Ngokuya Ngesiqondiso Se-OSHA Ekusetshenzisweni Kwe-Sling Okuphephile , umthwalo olinganiselwe we-sling ku-hitch yokuklinywa unqunywa umkhiqizi we-sling futhi usekelwe ku-engeli yokuklinywa. I-OSHA ithi umthamo we-choke hitch uyasebenza inqobo nje uma i-engeli yokuminyanisa ingamadigri angu-120 noma ngaphezulu. Kuma-engeli okuminyanisa ngaphansi kwamadigri angu-120, umthwalo olinganiselwe kufanele wehliswe ngokuqhubekayo ngokuvumelana nezincomo zomkhiqizi wesihlilingi .

 

Ishadi lokuqhathanisa amandla (kusekelwe ku-EN 1492-1 isilingi se-polyester flat):

 

Umthombo: Idatha ye-EN 1492-1 yomthamo evela ku-CEREX kanye ne-Mennens

 

Njengoba ithebula libonisa, i-choke hitch factor (KL) ingu-0.8 ngaphansi kwe-EN 1492-1, imele ukunciphisa umthamo ngo-20% uma kuqhathaniswa ne-vertical hitch.

 

Ngabe I-Choke Hitch Ifaneleka Nini?

I-choke hitch ifanelekile ezimweni ezithile:

 

1.Ilayisha ngaphandle kwamaphoyinti okunamathiselwe achaziwe —imithwalo eyisilinda, amapayipi, izinyanda zama-rebar, namakholomu kakhonkolo

 

2.Imithwalo edinga ukubanjwa ngokuvikelekile — igweme ukushelela phakathi nokuphakanyiswa noma ukuzungezisa

 

3.Ukuphakanyiswa komlenze owodwa —lapho ukushayisana kukabhasikidi kungenakwenzeka

 

Njengoba kuphawulwe i- Medeer Lifting , i- choke hitch iwusizo ekubambeni imithwalo ngokuphepha kodwa ayizinzi kakhulu kune-hitch eqondile futhi ingalimaza isihlilingi uma sisetshenziswa ngendlela engafanele . Izihlilingi kuphela eziklanyelwe ukusetshenziswa kokuklinywa okufanele zisetshenziswe kulokhu kumisa, futhi isihlilingi kufanele sihlolwe umonakalo ngaphambi nangemva kokusetshenziswa ngakunye.

 

Umkhuba ongcono kakhulu:  Lapho uklinywa, indawo yokuklinywa kufanele ibekwe phezu komzimba wendwayimane—ungalokothi ube seso, ku-splice, noma endaweni efanele. I-engeli yokuklinywa kufanele ibe ngu-120° noma ngaphezulu ukuze kugcinwe umthamo ogcwele ongu-0.8.

 

Ukucatshangelwa Okubalulekile Kokuphepha

Ungasebenzisi i-choke hitch uma:

 

● Isihlilingi sinomonakalo wokusikeka, ukuhuzuka, noma ukuthungwa endaweni ezothwala ukuklinywa

 

● I-engeli yokuklinywa ingaphansi kuka-120° ngaphandle kokunciphisa umthamo ohambisanayo

 

● Umthwalo unemiphetho ebukhali engasika imicu yesihlilingi (sebenzisa izivikeli zamakhona)

 

● Indwayimane isontekile noma iqinisiwe—lokhu kudala amaphuzu okucindezeleka angalingani

 

● Umazisi wesihlilingi awukho noma awufundeki—awukwazi ukuqinisekisa umthamo olinganiselwe.

 

I-OSHA ikwenqabela ngokusobala:

 

● Izihlilingi ezinamafindo (ukufinyeza noma ukunwetshwa ngokufiphaza noma ukusonta akuvunyelwe)

 

● Ukusebenzisa indwayimane lapho uklinywa ngephuzu lokuminyanisa entweni ehlanganisayo

 

● Ukubeka imithwalo esihlinini

 

● Ukudonsa indwayimane ngaphansi komthwalo lapho umthwalo uphezu kwesihlilingi

 

Ukuhlolwa kwelebhu ye- Lishenflex kuqinisekisa ukuthi izihlilingi ezinomonakalo ngisho omncane—njengokuhuzuka kwendawo noma ukusikeka onqenqemeni—ukuzwa ukuguga okusheshisiwe ekucushweni kwe-hitch ngenxa yamandla agxilile endaweni yokuminyanisa. Kungakho ukuhlola kwangaphambi kokusetshenziswa kanye nokuhlola njalo i-ASME B30.9 ngayinye kubaluleke kakhulu kuma-slings asetshenziswa ekuhitshisweni kokuklinywa.

 

Izidingo Zokuhlola Zokusebenzisa I-Choke Hitch

Izihlilingi ezisetshenziswa ekuvimbeni ukuklinywa kufanele zihlolwe kaningi kunalezo ezisetshenziswa ngokukhethekile ekuphakamiseni mpo. I-ASME B30.9  idinga amazinga amathathu okuhlolwa:

 

Inqubo yokususa engukhiye ngaphansi kwe-ASME B30.9  yezihlilingi eziyisicaba ezisetshenziswa ekuvinjweni kokuklinywa:

 

● Izithungo eziphukile noma ezigugile ezinceleni ezithwala imithwalo

 

● Ukusha kwe-Acid noma i-caustic

 

● Ubufakazi bokulimala kokushisa

 

● Izimbobo noma izinyembezi eziveza izintambo eziwumgogodla—ikakhulukazi lapho kuminyanisa khona

 

● Ukuguga ngokweqile

 

● Amafindo emzimbeni wendwayimane—ukubopha amafindo akuvunyelwe ngaphansi kwe-OSHA

 

● Ukushintsha umbala noma izindawo eziphukayo ezibonisa ukulimala kwamakhemikhali noma kwe-UV

 

Izincomo Ezifingqiwe Nezisebenzayo

Isihlilingi esiyisicaba  singasetshenziswa ekucushweni kwe-hitch, kodwa isicelo kufanele sisondele ngokuqapha nangobuchule.

 

Okuthathwayo okubalulekile:

 

1. Ukwehliswa kwamandla akuxoxiswana — ukugxambukela kunciphisa i-WLL ibe ngama-80% womthamo ome mpo ngaphansi kwe-EN 1492-1

 

2.I-engeli yokuminyanisa —gcina u-120° noma ngaphezulu ukuze uthole isici esingu-0.8 esigcwele; nciphisa umthamo wama-engeli amancane ngokwesiqondiso somkhiqizi

 

3. Ungalinge uminyaniswe isihlilingi noma ukuxhunywa —iphuzu eliminyanisayo kufanele libe phezu komzimba wendwayimana.

 

4.Hlola ngaphambi nangemva kokusetshenziswa -ukuminyanisa ukugxilisa ingqondo; hlola umonakalo owenziwe wasendaweni

 

5.Sebenzisa izivikeli zamakhona —ukulayisha izinto ezinemiphetho ebukhali

 

I-Lishenflex  ikhiqiza ama-polyester flat slings anamehlo aqinisiwe kanye nezimpawu zomthamo ezinemibala ecacile, ethobela i-EN 1492-1 namazinga we-ASME B30.9. Imikhiqizo yethu ihlolelwa zonke izilungiselelo ze-hitch, okuhlanganisa nokuklinywa, futhi sinikeza ukuqeqeshwa kokuhlola ukusekela izinqubo zokugebenga eziphephile.
