Ndingajoyina izilingi ezimbini eziFlethi Ndawonye ukwandisa Ubude?

Isilingi esicaba esiziimitha nje ezimbalwa mfutshane kakhulu sinokumisa umsebenzi wokuphakamisa. Ingcinga ekhawulezileyo: kutheni ungavele udibanise izilingi ezibini kunye? Inkqubo yokudibanisa i-slings ixhaphakile, kodwa ngokwe-OSHA 1910.184 (c) (2) kunye ne-ASME B30.9, ii-slings aziyi kufinyezwa okanye zandiswe ngokudibanisa okanye ukujija, okanye ukudibanisa ngokudibanisa.

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 yi-asidi. 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.
