Chidziwitso ichi ndi chachibadwa chokha chokhudza mfundo zazikulu zogwiritsira ntchito bwino Chain Lashings.Zitha kukhala zofunikira kuwonjezera chidziwitsochi pamapulogalamu enaake.Onaninso malangizo onse oletsa katundu, omwe aperekedwa patsamba lino.
NTHAWI ZONSE:
Yang'anani zomangira unyolo musanagwiritse ntchito.
● Mawerengereni mphamvu yothamanga yofunikira pa njira yosankhidwa yoletsa katundu.
● Sankhani mphamvu ndi kuchuluka kwa unyolo lashings kuti mupereke mphamvu yowerengeka
● Onetsetsani kuti malo okhomerera pagalimoto ndi/kapena katundu ali ndi mphamvu zokwanira.
● Tetezani kukwapula kwa unyolo kuchokera m'mphepete mwa ma radii ang'onoang'ono kapena kuchepetsa mphamvu yachitsulo motsatira malangizo a wopanga.
● Onetsetsani kuti zikwapu za unyolo zakhazikika bwino.
● Samalani pamene mukutulutsa zingwe za unyolo ngati katunduyo wakhala wosakhazikika kuyambira pamene zidazo zinagwiritsidwa ntchito.
OSATI:
● Gwiritsani ntchito zingwe za unyolo kuti munyamule katundu.
● Phunzitsani, kumanga kapena kusintha unyolo zingwe.
● Zikwapu za unyolo wambiri.
● Gwiritsani ntchito ziboliboli za unyolo pamphepete lakuthwa popanda kutchinga m'mphepete kapena kuchepetsa mphamvu yakumanga.
● Yang'anani ma chain lashing ku mankhwala popanda kufunsa wogulitsa.
● Gwiritsani ntchito ma chain lashings omwe ali ndi maulalo okhotakhota, ma tensioner owonongeka, zoikamo zowonongeka kapena chizindikiritso chosowa.
Kusankha Cholondola Chain Lashing
Muyezo wazitsulo za unyolo ndi BS EN 12195-3: 2001. Zimafuna kuti unyolo ugwirizane ndi EN 818-2 ndi zigawo zogwirizanitsa kuti zigwirizane ndi EN 1677-1, 2 kapena 4 monga momwe zilili zoyenera.Zida zolumikizira ndi kufupikitsa ziyenera kukhala ndi chipangizo chotetezera monga latch yachitetezo.
Miyezo iyi ndi ya zinthu za sitandade 8.Opanga ena amaperekanso magiredi apamwamba omwe, kukula kwa kukula kwake, amakhala ndi mphamvu yokulirapo.
Ma chain lashings amapezeka mumitundu yosiyanasiyana komanso kutalika kwake komanso masinthidwe osiyanasiyana.Zina ndi zolinga wamba.Zina zimapangidwira ntchito zinazake.
Kusankha kuyenera kuyamba ndikuwunika mphamvu zomwe zikugwira ntchitoyo.Mphamvu (zamphamvu) zomwe zimafunikira ziyenera kuwerengedwa molingana ndi BS EN 12195-1: 2010.
Kenaka fufuzani ngati malo otsekemera pa galimoto ndi / kapena katundu ali ndi mphamvu zokwanira.Ngati ndi kotheka gwiritsani ntchito kuchuluka kwa zikwapu kuti mufalitse mphamvu pazigawo zambiri zowombera.
Kukwapula kwa unyolo kumazindikiridwa ndi mphamvu yawo yowombera (LC).zowonetsedwa mu daN (deca Newton = 10 Newtons) Awa ndi mphamvu pafupifupi yofanana ndi kulemera kwa 1kg.
Kugwiritsa Ntchito Chain Lashings Motetezedwa
Onetsetsani kuti choponderezacho ndi chaulere kuti chigwirizane komanso kuti musapindike m'mphepete.Onetsetsani kuti tchenicho sichinapindikidwe kapena chopindika komanso kuti zotengerazo zikugwirizana bwino ndi mfundo zopumira.
Pazigawo ziwiri, onetsetsani kuti zigawozo zikugwirizana.
Onetsetsani kuti tchenicho chimatetezedwa ku nsonga zakuthwa ndi zazing'ono zozungulira ndi zotchingira zoyenera kapena zoteteza m'mphepete.
Zindikirani: Malangizo a wopanga akhoza kuloleza kugwiritsa ntchito m'mphepete mwa ma radius ang'onoang'ono pokhapokha mphamvu yobowoleza yachepetsedwa.
Kuyang'anira Ntchito ndi Kusunga
Zingwe za unyolo zitha kuonongeka pomangitsa unyolo m'mphepete ting'onoting'ono popanda chitetezo chokwanira.Komabe kuwonongeka kungachitike mwangozi chifukwa cha katundu woyenda poyenda motero ndikofunikira kuyang'ana musanagwiritse ntchito.
Kukwapula kwa unyolo sikuyenera kuwonetsedwa ndi mankhwala, makamaka ma asidi omwe angayambitse kuphulika kwa haidrojeni.Ngati kuipitsidwa mwangozi kumachitika, zokwiyitsa ziyenera kutsukidwa ndi madzi abwino ndikuloledwa kuti ziume mwachilengedwe.Mankhwala ofooka amatha kukhala amphamvu kwambiri chifukwa cha nthunzi.
Unyolo lashings ayenera kuyang'anitsitsa zizindikiro zoonekeratu zowonongeka musanagwiritse ntchito.Musagwiritse ntchito tcheni lashing ngati pali zolakwika zotsatirazi: zolemba zosawerengeka;maulalo amaketani opindika, otalikirapo kapena osapendekeka, zida zolumikizirana zopotoka kapena zosaoneka bwino kapena zomangira, zotchingira chitetezo zosagwira ntchito kapena zosowa.
Chain lashings idzayamba pang'onopang'ono pakapita nthawi.LEEA imalimbikitsa kuti aziwunikiridwa ndi munthu wodziwa bwino miyezi isanu ndi umodzi iliyonse ndi mbiri yopangidwa ndi zotsatira zake.
Zikwapu za unyolo ziyenera kukonzedwa ndi munthu wodziwa kutero.
Posungirako nthawi yayitali malo osungira ayenera kukhala owuma, aukhondo komanso opanda zowononga zilizonse.
Zambiri zikuperekedwa mu:
