Kodi ma alloy chain slings ndi chiyani?

Pankhani ya kulimba ndi kudalirika-ma alloy chain slings ndi ma bulldog okweza gulaye.Unyolo woponyera unyolo ungagwiritsidwe ntchito kukweza katundu wolemera kwambiri komanso wolemera kwambiri pafupipafupi kapena mobwerezabwereza.Mapangidwe awo osinthika amapereka mphamvu ndi kulimba kotero kuti athe kupirira kukhudzidwa, kutentha kwambiri, komanso kukhudzana ndi mankhwala ndi kuwala kwa UV.

Ma chain slings amawakonda kwambiri potengera kutentha kwambiri komanso kunyamula katundu wolemetsa.Mphamvu zawo ndi kulimba kwawo zimawalola kuti azigwiritsidwa ntchito m'mafakitale, mphero zachitsulo, masitolo ogulitsa makina olemera, ndi malo ena aliwonse pomwe kukweza mobwerezabwereza kapena zovuta zingawononge kapena kuwononga chingwe cha waya kapena nayiloni yopangira kapena polyester gulaye.Ngati chiwonongeko chilichonse chichitika pa gulaye, amatha kukonzedwanso ndipo amatha kuyesedwa-ndi kutsimikiziridwanso pambuyo pokonza.

Ma alloy chain slings amatha kutenthedwa mpaka kutentha kwa 1000°F, komabe Malire Ogwira Ntchito ayenera kuchepetsedwa malinga ndi wopanga's malingaliro pamene nthawi zonse amakhala ndi kutentha pamwamba pa 400°F.

Ma slings a unyolo amatha kukhazikitsidwa mumayendedwe amodzi-mwendo, 2-mwendo, 3-miyendo, ndi 4-miyendo.Zitha kusinthidwa kuti zigwiritsidwe ntchito muzitsulo zoyima, chokoka, kapena mabasiketi ndi mitundu yosiyanasiyana ya mbeza, utali wa unyolo, ndi maulalo apamwamba angagwiritsidwe ntchito popanga magulu osiyanasiyana a gulaye ntchito zosiyanasiyana.

Ngakhale pali mitundu yosiyanasiyana ya unyolo, alloy steel grade 63, 80, ndi 100 nthawi zambiri amalimbikitsidwa kuti anyamule pamwamba.Nthawi zina, zitsulo zopangira unyolo zopangidwa ndi zinthu zina osati zitsulo za alloy zitha kugwiritsidwa ntchito.Ntchitozi zimaphatikizapo malo owononga kapena kutentha kwambiri.Zida za unyolo muzinthu zapaderazi nthawi zambiri zimakhala zitsulo zosapanga dzimbiri kapena unyolo wina wapadera.Ngati tcheni chopanda alloy chikugwiritsidwa ntchito pokweza, timalimbikitsa kuti wogwiritsa ntchito alembe chifukwa chogwiritsira ntchito unyolo wina osati aloyi, komanso atsatire miyezo yonse yoyenera yoponyera unyolo kuphatikiza chizindikiritso cha gulaye ndi kuyendera.

The Design Factor for slings chain slings ndi 4: 1 chiŵerengero, kutanthauza kuti mphamvu yothyoka ya gulaye ndi yokwera kanayi kuposa malire a Ntchito Yogwira Ntchito.Ngakhale ma slings ali ndi kapangidwe kake, wogwiritsa ntchito sayenera kupitilira malire omwe adavotera Working Load Limit.
