Ndingasebenzisa i-Flet Sling kwi-Choke Hitch Configuration?

Iqela lokuqhawula kufuneka liphakamise umthwalo we-cylindrical-ipayipi yentsimbi, ikholamu yekhonkrithi, okanye i-bundle ye-rebar. I isilingi esithe tyaba  abasibamba kwirack bubude obuchanekileyo kunye nomthamo. Kodwa umthwalo awunazo iindawo zokuncamathela ezichaziweyo. Isixhobo sokulawula isilingi sisonga isilingi sijikeleze umthwalo, sigqithise iliso elinye kwelinye, size sisigxininise. Oku kukubetha-kwaye kunokuba sisisombululo esisebenzayo, kodwa kuphela xa kwenziwe ngokuchanekileyo.

 

I-Lishenflex  sele isenza izilingi ezisicaba zokwenziwa ngaphezulu kweminyaka engamashumi amabini, kwaye amava ethu entsimi abonisa ukuba iihitshi ezikrwitshiweyo ziphakathi kwezona zinto zisetyenziswa gwenxa. I-choke hitch ibonakala ilula, kodwa ukusetyenziswa kwayo okukhuselekileyo kuxhomekeke ekuqondeni ukunciphisa umthamo, i-angle yokuklitheka efanelekileyo, kunye nemeko yesilingi. Ngokutsho kwedatha ye-industry  evela kwi-EN 1492-1-ehambelanayo nabavelisi be-sling, i-choke hitch capacity factor yi-0.8-ithetha ukuba isilingi esilinganiselwe kwi-toni ye-1 ekuphakanyisweni okuthe nkqo sinokuthwala ngokukhuselekileyo i-800 kg kwi-choke hitch.

 

Yintoni i-Choke Hitch?

I-choke hitch yi-rigging configuration apho i-sling ijikelezwe ngumthwalo, kwaye enye isiphelo se-sling sidlula kwelinye iliso okanye kufanelekile. Emva koko umthwalo uyaphakanyiswa, nto leyo ebangela ukuba isilingi siqinise ukujikeleza umthwalo. Oku kudala i- cinching effect  ekhusela umthwalo kwaye inqande ukutyibilika.

 

Njengoko kuchaziwe kwi -OSHA's Guide on Safe Sling Use , i-choker hitch ifanelekile kwimithwalo enzima ukulinganisa okanye ukukhusela ngokuphakamisa ngokuthe nkqo. I-choker hitch ibamba umthwalo ngokukhuselekileyo ngokuyiqinisa ngeenxa zonke. Nangona kunjalo, i-OSHA ilumkisa ngokucacileyo ukuba kwi-hitch choke, indawo yokuklinywa kufuneka ibe kumzimba we-sling kuphela, ungalokothi ube kwi-splice okanye efanelekileyo.

 

I  -Rigging Institute  iphawula ukuba i-choke hitch yenye yezinto ezintathu eziphambili zokurhintyela isilingi, ecaleni kweehitshi ezithe nkqo kunye nebhasikithi, kwaye isetyenziswa ngokuqhelekileyo xa umthwalo ungenazo iindawo zokuncamathisela ezifanelekileyo.

 

Ukuncitshiswa koMmandla kwi-Choke Hitch

Eyona nto ibaluleke kakhulu ekusetyenzisweni kwe-hitch kukuncitshiswa kwamandla. Umda wokusebenza okalelwe kwisilingi uphezulu kutsalo oluthe nkqo oluthe nkqo. Xa isetyenziswe kwi-choke hitch, umthamo uyancipha kakhulu.

 

NgokweSikhokelo se -OSHA ngokuSetyenziswa kwe-Sling eKhuselekileyo , umthwalo olinganisiweyo we-sling kwi-hitch choke unqunywe ngumenzi we-sling kwaye usekelwe kwi-angle yokuxutywa. I-OSHA ichaza ukuba umthamo we-choke hitch uyasebenza ngaphandle kokuba i-angle ye-choke yi-120 degrees okanye ngaphezulu. Kwiengile zokukrwitsha ngaphantsi kwe-120 degrees, umthwalo olinganisiweyo kufuneka uncitshiswe ngakumbi ngokweengcebiso zomenzi wesilingi.

 

Itshathi yokuthelekisa amandla (esekelwe kwi-EN 1492-1 isilingi esisicaba sepolyester):

 

Umthombo: EN 1492-1 idatha yomthamo ovela kwi-CEREX kunye neMennens

 

Njengoko itheyibhile ibonisa, i-choke hitch factor (KL) yi-0.8 phantsi kwe-EN 1492-1, emele i-20% yokunciphisa umthamo xa kuthelekiswa nokubetha ngokuthe nkqo.

 

Ingaba i-Choke Hitch ifanelekile nini?

I-choke hitch ifanelekile kwiimeko ezithile:

 

1.Imithwalo ngaphandle kweendawo zokuncamathela ezichaziweyo -imithwalo yecylindrical, imibhobho, iinyanda zerebar, kunye neentsika zekhonkrithi

 

2.Imithwalo ekufuneka ibanjwe ngokukhuselekileyo —ithintele ukutyibilika xa iphakanyiswa okanye ijikeleziswa

 

3.Ukunyuswa komlenze omnye- apho ukubetha ngebhaskithi kungenakwenzeka

 

Njengoko kuphawuliwe nguMedeer Lifting , i-coke hitch iluncedo ekubambeni imithwalo ngokukhuselekileyo kodwa ayizinzile kangako kune-hitch ethe nkqo kwaye inokonakalisa isilingi ukuba isetyenziswe ngokungafanelekanga. Izilingi kuphela ezenzelwe ukusetyenziswa kwe-hitch ezixutywe kufuneka zisetyenziswe kolu lungelelwaniso, kwaye isilingi kufuneka sihlolwe umonakalo ngaphambi nangemva kokusetyenziswa ngalunye.

 

Eyona ndlela ilungileyo:  Xa ukrwitshwa, indawo yokukrwitshwa ifanele ibekwe kumzimba wesilingi—ungaze ube sesweni, kwiqhina, okanye kwindawo efanelekileyo. I-engile yokukrwitshwa kufuneka ibe yi-120 ° okanye ngaphezulu ukugcina umthamo opheleleyo we-0.8 factor.

 

Iingqwalasela ezingundoqo zoKhuseleko

Musa ukusebenzisa i-choke hitch ukuba:

 

● Isilingi sinomonakalo wokusikeka, ukukrazuka, okanye ukuthungwa kwindawo eza kukwazi ukukrwitshwa

 

● I-angle yokuminxa ingaphantsi kwe-120 ° ngaphandle kokunciphisa umthamo ohambelanayo

 

● Umthwalo uneencam ezibukhali ezinokusika iintsinga zesilingi (sebenzisa izikhuseli zekona)

 

● Isilingi sijijekile okanye sikrwitshiwe—oku kudala amanqaku angalinganiyo oxinzelelo

 

● Ithegi yesazisi sesilingi ayikho okanye ayifundeki—awukwazi kuqinisekisa umthamo olinganisiweyo.

 

I-OSHA iyakwalela ngokucacileyo:

 

● Izilingi ezinamaqhina (ukwenza mfutshane okanye ukolula ngeqhina okanye ukujija akuvumelekanga)

 

● Ukusebenzisa isilingi kwindawo ekrwitshayo kunye nenqaku lokukrwitsha kwindawo edibanisayo

 

● Ukubeka imithwalo kwisilingi

 

● Ukutsala isilingi phantsi komthwalo xa umthwalo uhleli kwisilingi

 

Uvavanyo lwelebhu ye- Lishenflex iqinisekisa ukuba izilingi kunye nomonakalo omncinci-ofana ne-abrasion yendawo okanye ukusikwa komphetho-amava akhawulezayo ukunxiba kwi-coke hitch configurations ngenxa yokuxinana kwamandla kwindawo yokuminxa. Kungenxa yoko le nto ukusetyenziswa kwangaphambili kunye nokuhlolwa rhoqo nge-ASME B30.9 ibaluleke kakhulu kwizilingi ezisetyenziswa kwiihitshi zokukrwitshwa.

 

IiMfuneko zokuHlola zokusetyenziswa kwe-Choke Hitch

Izilingi ezisetyenzisiweyo kwiihitshi zokukrwitshwa kufuneka zihlolwe rhoqo ngakumbi kunezo zisetyenziswa ngokukodwa xa kunyuswa ngokuthe nkqo. I-ASME B30.9  ifuna amanqanaba amathathu ohlolo:

 

Iikhrayitheriya zokususa eziphambili phantsi kwe-ASME B30.9  kwizilingi ezisicaba ezisetyenziswa kwiihitshi zokukrwitshwa:

 

● Ukuthungwa okwaphukileyo okanye okugugileyo kwiziqwenga ezithwala imithwalo

 

● Ukutsha kwe-asidi okanye i-caustic

 

● Ubungqina bomonakalo wobushushu

 

● Imingxuma okanye iinyembezi eziveza imisonto engundoqo—ingakumbi xa imisonto

 

● Ukunxitywa kwe-abrasive ngokugqithiseleyo

 

● Amaqhina kumzimba wesilingi—i-knotting ayivumelekanga phantsi kwe-OSHA

 

● Ukuguquka kombala okanye iindawo ezibhityileyo ezibonisa umonakalo wekhemikhali okanye we-UV

 

Isishwankathelo kunye neeNgcebiso eziSebenzayo

Isilingi esicaba  sinokusetyenziswa kuqwalaselo lwehitch, kodwa isicelo kufuneka sisondezwe ngononophelo kunye nobuchule.

 

Izinto eziphambili ezithathwayo:

 

I-1.Ukunciphisa umthamo akunakuxoxisana -i-choke hitch inciphisa i-WLL ukuya kwi-80% yomthamo othe nkqo phantsi kwe-EN 1492-1

 

2.Imiba ye-engile yokukrwitsha —gcina i-120° okanye ngaphezulu ukuze uphelele kwi-0.8 factor; ukunciphisa umthamo weengile ezincinci ngokwesikhokelo somenzi

 

3. Ungaze uminxeke kwisilingi okanye ekufakweni —indawo ekrwitshwayo mayibe kumzimba wesilingi.

 

4.Hlola ngaphambi nasemva kokusetyenziswa -ukubetha ugxininise kuxinzelelo; khangela umonakalo wendawo

 

5.Sebenzisa izikhuseli zekona -kwimithwalo enemiphetho ebukhali
