Umlinganiselo womthwalo osebenzayo
Singajonga le mifanekiso ingasentla kwaye sicinge ukuba ubomi bulula – kodwa abukhawulezi kangako!
Ngowuphi uMda wokuSebenza wokuSebenza (WLL) ekufuneka siwujonge?
Esi mhlawumbi sisihlandlo sokuqala kwiingxaki ezininzi esiza kujongana nazo.
Nge-sling yemilenze emininzi kufuneka siqinisekise ukuba yonke imilenze ye-sling kunye ne-Master Link ine-WLL eyaneleyo yomsebenzi. Sinokukhetha amacandelo ngendlela enye yeendlela ezimbini - sinokukhetha imilenze esiyidingayo kuqala, emva koko sikhethe i-Master Link ukutshatisa - okanye sinokukhetha i-Master Link kuqala, emva koko sifumane imilenze yesilingi enegunya elaneleyo elilinganisiweyo.
Ukwenza olu balo kufuneka siqale sazi i-engile yesilingi.
E-Australia le nto iya kuba yi-angle edibeneyo phakathi kwemilenze ye-sling, kwaye i-WLL ephezulu esinokuyinika iya kubalwa kwii-degrees ezingama-60.
I-Angle yase-Australia yesiLingi esemgangathweni yokubala ubuninzi be-WLL.
Ukuba ne-60 ° yokukala ekhoyo kuthi kunokuba luncedo kakhulu kuba inceda ukunyusa umthamo onokwenzeka kunye nokusebenziseka kwezilingi zethu.
Kukho nokubanjiswa – kwaye ngumgangatho oxhaphakileyo waseYurophu (umgangatho weEN) .
Ii-Engles zokuLinga eziMgangatho zaseYurophu zokubala ubuninzi be-WLL.
Apha i-engile ilinganiswa ukusuka ngokuthe nkqo, kwaye akuyongxaki enjalo - kodwa i-WLL ephezulu ibalwa kuma-45 ° elingana ne-90 ° yase-Australia equkiweyo yoluhlu lwe-engile. Ngamafutshane, kuthetha ukuba ubungakanani obunikiweyo bekhonkco, ubuninzi be-WLL yesilingi kunye nekhonkco elihambelanayo elihambelanayo lincinci.
Kwi-angle ye-sling edibeneyo ye-60 °, i-master link WLL kufuneka ibe ubuncinane ngamaxesha angama-1.73 umlenze we-WLL.
Kwi-angle ye-sling edibeneyo ye-45 °, i-master link WLL kufuneka ibe ubuncinane amaxesha angama-1.41 umlenze we-WLL.
Kukwathetha ukuba ukhetho lwemveliso kunye nokuhambelana okudweliswe eYurophu akuyomfuneko ukuba isebenze e-Australia.
Layisha Yabelana
Izilingi ezinemilenze emine zenza iphiramidi. Oku kuluncedo kuba imithwalo emininzi ikwimo exande – kodwa inengxaki engokwemvelo kwaye oko kukungaqinisekanga okuzinzileyo. Ukubeka nje, imilenze ayibelani ngomthwalo ngokulinganayo.
Ngapha koko, kukho ubhejo oluqinisekileyo kuphela xa kufikwa kumthwalo wesabelo kwaye oko kubungakanani bamacandelo ngokungathi babelana ngomthwalo emilenzeni emibini kuphela… yiloo nto eyenziwa yiMigangatho yaseOstreliya – kwaye sinokwenza uvavanyo olubonisa ukuba bubulumko ukwenza oko. .
Kuthetha ukuthini kwindibano yethu ye-Master link nangona kunjalo kukuba zombini ikhonkco elingasentla kunye nekhonkco elisezantsi eliphakathi kufuneka lihlangabezane nobuncinci be-WLL yendibano ukuba kuqwalaselwa kwimilenze emibini.
Ngokwe-AS3775 oku kuthetha ukuba:
IiMfuno zeNdibano eziPhambili zase-Australia.
Kwakhona, imithetho yaseYurophu iyahluka. Into abayivumelayo kukulinganisa izilingi ezine zomlenze kwimilenze emithathu. Ngokuqinisekileyo isilingi semilenze emine asinako ukuzixhasa ngokwaso ngemilenze emithathu - yindlela esekelwe kumanani kuphela.
Le yenye yezinto ezithi ngamanye amaxesha zisebenze kwaye ngamanye amaxesha zingasebenzi. Kwiimeko apho imithwalo yentlawulo iqinile kwaye kumathuba apho umlinganiselo wesilingi usondela kwimilo yephiramidi yokwenyani, isabelo somthwalo phakathi kwemilenze sinokuba sibi kakhulu kwaye isilingi kufuneka sincitshiswe ukuchazwa kwesiphumo semilenze exegayo.
Ithetha ukuthini ekukhethweni kweendibano ze-Master Link nangona kunjalo kukuba xa i-master link i-WLL icatshulwe njengexabiso elinye phesheya kolwandle- oku kunokuthetha ukuba amakhonkco aphakathi awomelele ngokwaneleyo.
I-European Master Link isebenza ngolu hlobo:
Oku kusebenza kunye nemigangatho ye-sling ye-EN, kodwa ayihambelani nendalo kunye neMigangatho yase-Australia. Okubalulekileyo, ayisiyiyo nje isidenge kumsebenzisi - oko kukuthi, ngaphandle kokuba ukhetho lwemveliso lwenziwe ngononophelo ukutshatisa imithetho yesilingi ye-AS3775.
I-European Standard Master Link Assemblies inokufuna ukuncitshiswa ukwenzela ukuba amakhonkco aphakathi aqine ngokwaneleyo.
Ukufaka iCrane Hook
Abasebenzisi abaninzi be-sling bajongana nomcimbi wokwenza izilingi zisebenze ngee-crane hook. Ingaba i-crane hook incinci kakhulu kwi-tackle yokuphakamisa - okanye i-tackle yokuphakamisa incinci kakhulu kwi-crane hook.
Ukudibanisa i-masterlink kwi-crane hook, isilumkiso esikhethekileyo siyacelwa kunye neendibaniselwano eziqinileyo.
Zonke iigwegwe zecrane zenziwe ukuba zomelele ekugobeni kwinqwelomoya enye. Ukwandisa ukusebenza kakuhle kwamandla basebenzisa icandelo lomnqamlezo elinzulu kunokuba libanzi, kwaye lityebile ngaphakathi kunangaphandle.
Ukujonga ukufaneleka kwe-Masterlink kunye ne hook.
Ukuxinana ngokugqithisileyo
Sifuna amakhonkco ethu abe made ngokwaneleyo ukuze alingane izinto ezinje ngeehuku zecrane phezulu kunye nofakelo ezantsi - kodwa njengoko sibona ngasentla, rhoqo kufuneka zibe banzi ngokwaneleyo.
Oku akuyomfuneko kuphela kwi-crane hook. Iyimfuneko kujongano lomlenze wesilingi.
Ukuba iindawo zokukhwelana azikwazi ngokwemvelo ukuhlala kwikhonkco kwaye zithwale imithwalo ngokuchanekileyo amakhonkco agcwele kakhulu. Oku kugxininisa amalungu ngeendlela ezingaqhelekanga kwaye akuvumelekanga.
Ukuxinana okugqithisileyo kunokuba yintloko yokwenyani ingakumbi apho i-masterlink isetyenziswa kunye nezilingi zeentambo zocingo.
