Ithetha ntoni iKhowudi yoMbala kwiLifting Slings?

Isilingi esiphakamisayo siza kumbala othile—kodwa loo mbala awungowobuhle kuphela. Ngokutsho kwe-EN 1492-1 (i-flat webbing slings) kunye ne-EN 1492-2 (ii-slings ezijikelezayo), umbala ngamnye uhambelana ne-Working Load Limit (WLL) ethile, eyenza ukuchongwa kwamandla okukhawuleza kunye nokulula kwindawo yomsebenzi.

Buthini ubomi beRound Sling?

Isilingi esingqukuva asizi nomhla wokuphelelwa kwesitampu kwileyibhile yaso—kodwa oko akuthethi ukuba sihlala ngonaphakade. Ngokutsho kwe-EN 1492-2, umgangatho waseYurophu wee-roundslings, umda womthwalo wokusebenza (WLL) kunye nokhuseleko luchazwe, kodwa ubomi benkonzo buxhomekeke kwiimeko zokusetyenziswa zangempela. Abanye abavelisi bachaza ubuninzi beminyaka eyi-10 ukusuka kusetyenziso lokuqala phantsi kweemeko ezifanelekileyo.

I-Polyester vs. I-Nylon Flat Slings: Ukumelana nemichiza kunye neeProfayili zokwandisa

Ukukhetha phakathi kwe-polyester flat isilingi kunye ne-nylon flat isilingi asingombandela wokuba enye 'ingcono' kunomnye-kuxhomekeke ngokupheleleyo kwimeko yesicelo. Zombini izixhobo zabelana ngemilinganiselo efanayo yomthwalo wokusebenza kunye noluhlu lweqondo lokushisa (-40 ° C ukuya kwi-100 ° C) phantsi kwe-EN 1492-1, kodwa zihluke kakhulu ekwandiseni, ukuchasana kweekhemikhali, kunye nokuphendula komswakama. Inayiloni yolula i-6-10% kumthwalo olinganisiweyo kwaye ixhathisa i-alkali kodwa itshatyalaliswe ziiasidi. I-polyester yolula kuphela i-3-4% kwaye ixhathisa i-asidi kodwa yonakaliswe yi-alkalis. Esi sikhokelo sinika uthelekiso oluneenkcukacha zokunceda iinjineli kunye neengcali zokurhweba ukuba zikhethe izinto ezifanelekileyo zesilingi esicaba kwiimeko zabo zokusebenza ezithile.

Ukubuyisela nini i-Flat Slings: Isikhokelo kwiikhrayitheriya zokuHlola rhoqo kunye namaxesha athile

Ukwazi ixesha lokutshintsha izilingi ezicaba kubalulekile ekukhuselweni kokhuseleko kunye nokuthotyelwa kwemithetho. Imigangatho yeShishini i-ASME B30.9 kunye ne-EN 1492-1 ichaza amanqanaba amabini okuhlola-rhoqo (ukusetyenziswa kwemihla ngemihla okanye kwangaphambili) kunye namaxesha (ngonyaka okanye okwesiqingatha sonyaka)-ngalinye lineenqobo ezikhethekileyo zokumisela ukuba isilingi kufuneka sisuswe nini enkonzweni. Esi sikhokelo sichaza umahluko phakathi kokuhlolwa rhoqo kunye namaxesha ngamaxesha, sibonelela ngoluhlu lokukhangela oluneenkcukacha ngalunye, kwaye sichaza iindlela zomhlalaphantsi ezibangela ukutshintshwa kwesilingi. Kubaphathi bokurhwaphiliza, abaphathi bokhuseleko, kunye nabaqhubi, le yireferensi ebonakalayo yokugcina uluhlu olukhuselekileyo lwesilingi.
