EN81-20 le EN81-50, litekanyetso tse peli tse ncha tsa polokeho bakeng sa kaho ea lifti le tlhahlobo ea lisebelisoa tsa lifti, li ne li sebelisoa khafetsa 'me li tla laoloa hantle ke batho ba indasteri ea lifti. Ho thusa ho ithuta hantle ka litekanyetso, mona re kentse lipotso tse botsoang khafetsa.
1. Liphapang tse kholo lipakeng tsa litekanyetso ke life le hore na li sebetsa hokae?
Phahamiso efe kapa efe ea bapalami e kentsoeng ts'ebeletso ka mor'a la 31 Phato 2017 e hloka ho latela maemo a EN20/50. Maemo a khale a EN81-1 le EN81-2, a hlahisitsoeng ka 1998 ha a sa sebetsa 'me a sebetsa bakeng sa lifti tse fanoeng pele ho letsatsi lena.
Litekanyetso tsa morao-rao tsa phahamiso ea bapalami li fana ka polokeho e kholo ea phahamiso, phihlello le boiketlo ho bapalami le lienjiniere tsa litšebeletso. Litekanyetso li boetse li fana ka lipehelo mabapi le moralo oa moaho le sebopeho.
EN81-20: 2020 (ka molao EN81-20: 2014) e akaretsa litlhoko tsa moaho ha li ntse li sebetsa ho moralo oa shaft ea lifti. EN81-50:2020 (Melao ea ts'ireletso bakeng sa kaho le ho kenya lifti) (ka molao EN81-50:2014) e akaretsa melao ea moralo, lipalo le tlhahlobo le tlhahlobo ea likarolo tsa lifti mme ke ea lik'hamphani tsa ho kenya lifti ho latela.
Maemo ana ka bobeli a sebetsa bakeng sa lilifi tsa bapalami le thepa tse oelang tlas'a Lifts Directive. Litekanyetso tsena ha li koahele lilifti tse tsamaisang bapalami tse lebelo le ka tlase ho 0.15m/s kapa lilifti tsa thepa feela (Lilifti tsa Mechine ea Directive).
2. Ke liphetoho life tse ka sehloohong tse lokelang ho nahanoa ha ho raloa mehaho?
EN81-20:2020 (ka molao EN81-20:2014) e akaretsa litlhoko tsa moaho ha li ntse li sebetsa ho moralo oa shaft ea lifti. Liphetoho ho tloha ha maemo a khale a bolela ka ho khetheha:
● Tumello ea sebaka bakeng sa libaka tsa setšabelo e fetohile kahoo ho ka 'na ha hlokahala hore ho be le botebo bo boholoanyane ba sekoti le kamore e ka holimo bakeng sa lifti, haholo-holo litekanyong tse nyenyane tsa lifti.
● Mabota a shaft a tlameha ho hahoa ka matla a lekaneng ho mamella matla a 1000N
● Moo e kentsoeng e le karolo ea leano la mollo oa mohaho, lisistimi tsa lifti tsa ho fafatsa ka shaft li ka kenngoa empa ts'ebetso ea tsona e tla khoneha ha feela lift e eme sebakeng seo ho lulisang ho sona 'me phepelo ea motlakase ea li-circuits tsa lifti le mabone e tingoa ke mollo. kapa tsamaiso ea mosi. (Sena ha se sebetse ho liliba tsa ho phahamisa mollo le libaka tsa mochini, leha ho le joalo, moo lisebelisoa tsa ho fafatsa li sa lumelloeng)
● Boikarabello ba moea oa moea oa shaft bo oela ho moqapi oa mohaho
● Keketseho ea mabone a khantšitsoeng ka har'a shaft ea lifti
● Tšireletso e khōloanyane mabapi le motsamao o sa reroang le lebelo le feteletseng
● Mabone a koloi a khanyang haholoanyane
● Ho hloekisoa ho ntlafetseng ha likharetene tse khanyang mamating ho qoba hore lintho tse nyenyane li tšoasoe
● Matla a ntlafetseng le ho tšoarella ha marako a koloi, marulelo, mamati le mamati a thellang
● Matla a eketsehileng a hlokahalang bakeng sa khalase ea tšireletso e sebelisoang koloing ea ho phahamisa kapa mohaho oa shaft le khalase e tlameha ho ba laminated
● Litlhoko tse phahameng tsa ho hanyetsa mollo oa ka hare ho koloi
● Mehaho e nyenyefalang e nkoang e le moralo oa lifti bakeng sa meaho e fetang 40m ho netefatsa boleng bo phahameng ba ho palama
3. Na litlhoko tsa moralo bakeng sa lifti ea baeti li fetohile?
Boholo, litlhoko tsa moralo tsa EN81-20 li tla koaheloa ke moetsi oa lifti mme li boletsoe litšoantšong tsa mosebetsi oa sehahi.
Haeba ho khethiloe mabota le lithako tsa fatše, mohlala, lithapo tsa lifti tsa bespoke tse tsamaellanang le moralo oa moaho. Lisebelisoa tse sebelisetsoang mekato ea likoloi, mabota le siling li tlameha ho fihlela litlhoko tsa sehlopha sa mollo tse boletsoeng ho EN 135001-1. Mekhahlelo e fokolang ke:
● Siling: C, s2 le d0
● Mabato: Cfl. s2
● Mabota: C, s2 le d1
Likarolo tsa 'C' le 'Cfl' tse ka holimo li bua ka karabelo ea mollo le 's' le 'd' li bolela ho hlophisoa ha lintho tse amanang le mosi le sebopeho sa marotholi le likaroloana tse tukang ka ho latellana.
4. Ho etsahala'ng haeba morero oa ka o sa lumellane le molao?
Maemong a 'maloa moo ho sa khoneheng ho kenya lift ka botlalo ho EN81-20 ho na le khetho e ka bang teng ea hore moralo o amoheloe tlasa Litlhoko tsa Bohlokoa tsa Bophelo bo Botle le Tšireletseho (EHSRs) tsa Melao ea Phahamiso bakeng sa likarolo tseo tsa lift tse fapohang. maemo, a netefatsang ho latelwa ka setifikeiti sa Tlhatlhobo sa Moralo ho tswa ho Sehlopha se Tsebisoang le hoja maemo a morao-rao esale a le teng ka nako e telele, lilifti tse ngata li hloka ho lumellana ho tloha qalong.
5. Ho thoe'ng ka lifti tse teng?
Tekanyetso e ncha e amehileng ka lifti e kentsoeng ka mor'a la 31 Phato 2017. Leha ho le joalo, litekanyetso tsena li hlalosa mokhoa o motle ka ho fetisisa, ka molemo oa tšireletso e ntlafetseng. Haeba u nahana ho ntlafatsa lifti le tlhokomelo, rona Bluetech re tla u thusa ho u eletsa mabapi le theknoloji ea morao-rao le melaoana ho u thusa ho ntlafatsa lifti ea hau.
Kakaretso
Joaloka moetsi le mofani oa thepa ea hloahloa, Bluetech e ke ke ea u fa feela thuso le ts'ehetso eo u e hlokang ho u lumella ho fihlela litekanyetso tsena kapele le ha bonolo ho khoneha. Lilifisi tsohle tsa rona li lumellana ka botlalo le maemo a morao-rao a EN81-20 le EN81-50 'me re thabela ho fana ka likeletso mabapi le maemo a lifti.
