Ma Links ndi ma Rings ndi mtundu wamba wa zida zomangira, zomwe zimakhala ndi lupu imodzi yachitsulo. Mwina mwawonapo mphete yayikulu ikugona mozungulira shopu kapena ulalo wozungulira wopachikidwa pa mbedza ya crane. Komabe, ngati ndinu watsopano ku makampani opanga ma Rings kapena simunagwiritsepo ntchito ulalo kapena mphete kale, sizingakhale zomveka bwino chifukwa chake zipangizo zosavutazi ndizofunikira kwambiri pomanga chokweza chapamwamba.
Taona kuti pankhani ya maulalo ndi mphete, zambiri zenizeni komanso zaukadaulo zimapezeka pa intaneti. Komabe, zambiri zokhudza zomwe zipangizozi zilili ndi zomwe zimagwiritsidwa ntchito sizikupezeka.
Kwa makasitomala omwe angakhale atsopano ku zinthu zokhudzana ndi kugula zinthu, kuyamba ndi mfundo zoyambira komanso zozikidwa pa ntchito ndikofunikira musanalowe muzinthu zovuta kwambiri. Ichi ndichifukwa chake talemba nkhaniyi.
Munkhaniyi, mutha kuyembekezera kuphunzira:
• Kodi maulalo ndi mphete ndi chiyani komanso zomwe zimagwiritsidwa ntchito
• Mitundu yosiyanasiyana ya maulalo ndi mphete ndi chiyani?
• Zizindikiro/zizindikiro za maulumikizidwe ndi mphete
• Kuchotsa maulalo ndi mphete kuchokera pazifukwa zogwirira ntchito
1. Kodi ma Links ndi Rings ndi chiyani?
Zolumikizira ndi mphete ndi zinthu zofunika koma zofunika kwambiri pakukweza ndi kukonza. Ndi zipangizo zozungulira—zofanana ndi diso—zomwe zimagwiritsidwa ntchito popanga malo olumikizirana mu zomangira ndi zomangira kuphatikizapoma sling a unyolo, zingwe zolumikizira chingwe, zingwe zolumikizira ulusi, ndi zina zotero.
Ma link ndi mphete nthawi zambiri amagwiritsidwa ntchito ngati malo olumikiziranamisonkhano ya miyendo yambiri—nthawi zambiri unyolo kapena chingwe cha waya. Zingagwiritsidwe ntchito ngati malo olumikizirana a mayendedwe amodzi, awiri, atatu, kapena anayi a sling-leg.
Ma master links ndi mphete—ma oblong master links, master rings, ndi ma master links okhala ngati peyala—amatchedwanso kuti collector rings kapena collector links, chifukwa “amasonkhanitsa” miyendo yambiri yolumikizirana kukhala imodzi.
Kuwonjezera pa kugwiritsidwa ntchito polumikiza zinthu zolumikizirana, maulalo ndi mphete zingagwiritsidwenso ntchito ngati malo olumikizirana pakati pa magawo awiri aliwonse a cholumikizira. Mwachitsanzo, mungagwiritse ntchito ulalo kapena mphete kulumikiza:Chingwe chomangira pa mbedza ya crane,Lumikizani ku mbedza,Ulalo wa mbedza yoponyedwa ndi sling
2. Mitundu ya Maulalo ndi Mphete
Pali mitundu yosiyanasiyana ya maulalo ndi mphete zomwe zingagwiritsidwe ntchito pomanga. Mitundu yodziwika kwambiri ya maulalo ndi mphete ndi iyi:Maulalo a oblong master,Misonkhano yaying'ono ya ulalo waukulu,Maulalo ooneka ngati peyala,Mphete za Master,Maulalo olumikizirana
Maulalo ozungulira angagwiritsidwenso ntchito kulumikiza shackle ku mbedza ya crane, mbedza ku shackle, ndi makonzedwe ena osiyanasiyana a zingwe.
Ma sub-assemblies amakhala ndi ma master coupling links awiri olumikizidwa ku oblong master link. M'malo momangirira miyendo yonse inayi ya sling ku master link, tsopano akhoza kugawidwa pakati pa ma sub-assemblies awiriwa.
Kugwiritsa ntchito ma sub-assemblies kumathandiza kuchepetsa kukula kwa master link—ma master link akuluakulu kwambiri amatha kupitirira mainchesi atatu m'mimba mwake—pomwe akusunga Working Load Limit (WLL) yofanana ndi master link yayikulu kwambiri.
Kapangidwe ka mapeyala a maulalo awa kamapangitsa kuti akhale abwino kugwiritsa ntchito ndi zingwe zopapatiza kwambiri. Nthawi zina, chingwe chooneka ngati peyala chidzakhala chogwirizana bwino kuposa chingwe chachikulu chozungulira, chomwe chimachotsa kuyenda kwa katundu kuchokera mbali imodzi kupita mbali pamwamba pa chingwecho.
Mawonekedwe ozungulira a mphete yayikulu amachititsa kuti ikhale yosayenera kwambiri kuposa cholumikizira chachikulu cholumikizira ku zingwe zazikulu, zozama za crane. Mphete zazikulu nthawi zambiri zimagwiritsidwa ntchito popanga zinthu kapena m'masitolo ang'onoang'ono amakina ndipo mwanjira ina, sizigwiritsidwa ntchito kawirikawiri. Nthawi zambiri, cholumikizira chachikulu chozungulira chingagwiritsidwe ntchito m'malo mwake.
Maulalo olumikizirana akhoza kukhala amakina kapena olumikizidwa ndipo amagwiritsidwa ntchito makamaka kulumikiza gawo la unyolo ku ulalo waukulu kapena ku cholumikizira. Angagwiritsidwenso ntchito kupanga kulumikizana pakati pa maulalo akuluakulu, ma hook, kapena zida zina zamakina.
Maulalo olumikizirana olumikizidwa, monga maulalo ena onse mu unyolo, amalumikizidwa ku ulalo waukulu kapena cholumikizira kumapeto ndipo amatsekedwa kuti apange kulumikizana.
Chithunzi chomwe chili mu gawoli chikuwonetsa njira ziwiri zosiyana zomwe ulalo wolumikizira wolumikizidwa ungagwiritsidwe ntchito. Pachithunzi chakumanzere, ulalowu umalumikizidwa kosatha ku mbedza ya maso ndipo umagwiritsidwa ntchito kulumikiza chipangizocho ku mbedza yozungulira. Kumanja, maulalo olumikizira wolumikizidwa amagwiritsidwa ntchito kulumikiza miyendo ya unyolo ndikugwira zingwe ku ulalo waukulu.
Hammerlok® Yasonkhanitsidwa ndi Kuchotsedwa
Mayina atatu odziwika bwino a maulalo olumikizira makina ndi awa:
• Hammerlok® (mtundu wa CM)
• Kuplex® Kuplok® (mtundu wa Peerless)
• Lok-a-Loy® (mtundu wa Crosby)
Kuplex® Kupler®, yomwenso ndi chinthu chopanda Peerless, ndi mtundu wina wodziwika bwino wa cholumikizira chamakina. Zolumikizira izi zimakhala ndi mawonekedwe osiyana pang'ono ofanana ndi shackle. Pali theka limodzi lokha la thupi lomwe kulumikizana kumapangidwa ndi pini yonyamula katundu ndi pini yosungira. Popeza palibe magawo awiri a thupi, Kuplex® Kupler® siimangirira pakati.
Kukhazikitsa kwa Chain Sling Pogwiritsa Ntchito Maulalo Angapo a Kuplex® Kupler®
3. Zizindikiro / Kuzindikiritsa Zolumikizirana ndi Mphete
Malinga ndi ASME B30.26 Rigging Hardware, cholumikizira chilichonse, cholumikizira chachikulu, ndi mphete ziyenera kulembedwa ndi wopanga kuti ziwonetse:
• Dzina kapena chizindikiro cha kampani ya wopanga
• Kukula kapena katundu wovomerezeka
• Giredi, ngati pakufunika kudziwa kuchuluka kwa katundu woyesedwa
4. Kuchotsa Maulalo ndi Mphete Kuchokera ku Zikhalidwe za Utumiki
Pa nthawi yowunikira, chotsani maulalo aliwonse, ma sub-assemblies a master link, ndi mphete kuti zisagwiritsidwe ntchito ngati pali chilichonse mwa zinthu zomwe zalembedwa mu ASME B30.26 Rigging Hardware.
• Chizindikiro chosowa kapena chosawerengeka
• Zizindikiro za kuwonongeka kwa kutentha, kuphatikizapo kufalikira kwa weld kapena kugwedezeka kwa arc
• Kutupa kwambiri kapena kubowola
• Zopindika, zopindika, zopotoka, zotambasuka, zotalikira, zosweka, kapena zosweka zonyamula katundu
• Kutupa kwambiri kapena kutsekeka kwa minofu
• Kuchepetsa 10% kwa gawo loyambirira kapena la katalogi nthawi iliyonse
• Umboni wa kuwotcherera kapena kusintha kosaloledwa
• Mavuto ena, kuphatikizapo kuwonongeka komwe kumawoneka komwe kumayambitsa kukayikira ngati kugwiritsa ntchito kupitiriza
Ngati pali chilichonse mwa zinthu zomwe zili pamwambapa, chipangizocho chiyenera kuchotsedwa pa ntchito ndipo chiyenera kubwezeretsedwanso ku ntchito pokhapokha ngati chavomerezedwa ndi munthu woyenerera.
5. Kumaliza
Tikukhulupirira kuti nkhaniyi yakuthandizani kumvetsetsa bwino zomwe maulumikizidwe ndi mphete zili, zomwe zimagwiritsidwa ntchito, komanso zofunikira zokhudzana ndi kuzindikira ndi kuwunika mu ASME B30.26 Rigging Hardware.
Mwachidule, maulalo ndi mphete zimagwiritsidwa ntchito ngati malo olumikizirana mu gulu la zingwe kapena gulu la zingwe zambiri. Ngakhale pali mitundu yosiyanasiyana ya maulalo ndi mphete zomwe zimagwiritsidwa ntchito polumikiza zingwe, maulalo akuluakulu ozungulira ndi omwe amagwiritsidwa ntchito kwambiri komanso nthawi zambiri.mphete zosonkhanitsira.
Maulalo olumikizira amagwiritsidwa ntchito kulumikiza magawo a unyolo ku mphete yolumikizira kumapeto kapena mphete yosonkhanitsira ndipo akhoza kukhala amakina kapena olumikizidwa.
Monga chida china chilichonse chopangira zida, onetsetsani kuti mukutsatira miyezo yoyenera ya ASME ndikuchotsa pazifukwa zogwirira ntchito.
