2. Mefuta e Meholo ea Li-Conveyor tse Sebelisang Liketane tsa Lihokelo tse Potolohileng
2.1 Lifti tsa Libakete
Li-lifti tsa libakete ke litsamaiso tsa ho fetisa tse otlolohileng tse sebelisangliketane tse chitja tsa lihokeloho phahamisa thepa e ngata ka potoloho e tsoelang pele. 'Maraka oa lefats'e oa liketane tsa lifti tsa libakete o bohlokoa, ka boleng bo lebelletsoeng ba USD 75 milione ka 2030. Litsamaiso tsena li arotsoe haholo-holo ka tokisetso ea tsona ea ketane:
* Lifti tsa Libakete tsa Ketane e le 'Ngoe: Sebelisa khoele e le 'ngoe ea ketane e chitja ea khokahano eo libakete li khomaretsoeng ho eona. Moralo ona hangata o khethoa bakeng sa meroalo le bokhoni bo itekanetseng.
* Lifti tsa Libakete tse Habeli tsa Ketane: Sebelisa likhoele tse peli tse bapileng tsa ketane ea khokahano e chitja, tse fanang ka botsitso bo ntlafalitsoeng le bokhoni ba ho jara mojaro bakeng sa thepa e boima, e khorofong haholoanyane, kapa e nang le bophahamo bo boholo.
Lifti tsena ke motheo oa phallo ea thepa liindastering tse kang samente le liminerale, moo ho phahamisa ka mokhoa o tšepahalang ho leng bohlokoa.
2.2 Li-conveyor tse ling
Ka nqane ho ho phahamisa ka ho otloloha,liketane tse chitja tsa lihokeloke tsa bohlokoa meralong e 'maloa ea conveyor e otlolohileng le e sekametseng.
* Li-Conveyor tsa Ketane le Libakete: Le hoja hangata li amahanngoa le lifti, molao-motheo oa ketane le bakete o boetse o sebelisoa ho li-conveyor tsa phetisetso tse otlolohileng kapa tse sekametseng butle.
* Li-Conveyor tsa Ketane le Pan/Slat (li-scraper): Litsamaiso tsena li na le liketane tse chitja tsa khokahano tse hokahaneng le lipoleiti tsa tšepe kapa li-slat (ke hore, li-scraper), tse etsang sebaka se tiileng se tsoelang pele bakeng sa ho tsamaisa meroalo e boima kapa e khorofo ea yuniti.
* Li-Conveyor tsa Trolley tse ka Holimo: Litsamaisong tsena, liketane tse chitja tsa khokahano (hangata li leketliloe) li sebelisoa ho tsamaisa lintho ka mekhoa ea tlhahiso, kopano, kapa pente, tse khonang ho tsamaea litseleng tse rarahaneng tsa mahlakore a mararo ka ho reteleha le liphetoho tsa bophahamo.
3. Ho aroloa ha Liketane tsa Lihokelo tse Potolohileng
3.1 Boholo le Litekanyo
Liketane tsa lihokelo tse chitjadi etswa ka mefuta e fapaneng ya boholo bo tloaelehileng ho dumellana le ditlhoko tse fapaneng tsa mojaro. Diparamitha tsa bohlokwa tsa boholo di kenyeletsa:
* Bophara ba terata (d): Botenya ba terata ea tšepe e sebelisoang ho etsa lihokelo. Ena ke eona ntho ea bohlokoa e khethollang matla a ketane.
* Bolelele ba Sehokelo (t): Bolelele ba ka hare ba sehokelo se le seng, bo susumetsang ho tenyetseha le bophahamo ba ketane.
* Bophara ba Sehokelo (b): Bophara ba ka hare ba sehokelo se le seng.
Mohlala, liketane tse chitja tse tsamaisang lihokelo tse fumanehang khoebong li na le bophara ba terata ho tloha ho tse nyane tse ka bang 10 mm ho isa ho tse fetang 40 mm, 'me bolelele ba lihokelo tse kang 35 mm bo tloaelehile.
3.2 Matla le Dikereiti tsa Thepa
Tshebetso eaketane ea khokahano e chitjae hlalosoa ke sebopeho sa eona sa thepa le boemo ba matla, tse amanang ka kotloloho le mojaro oa eona oa ho sebetsa le mojaro oa ho robeha.
* Sehlopha sa Boleng: Liketane tse ngata tsa lihokelo tse chitja tsa indasteri li hlahisoa ho latela maemo a kang DIN 766 le DIN 764, e hlalosang lihlopha tsa boleng (mohlala, Sehlopha sa 3). Sehlopha se phahameng se bontša matla a maholo le ntlha e phahameng ea polokeho lipakeng tsa mojaro o sebetsang le mojaro o fokolang oa ho robeha.
* Lisebelisoa: Lisebelisoa tse tloaelehileng li kenyelletsa:
* Tšepe e kopantsoeng: E fana ka matla a ho thaepa a phahameng 'me hangata e koahetsoe ka zinki bakeng sa ho hanyetsa mafome.
* Tšepe e sa ruseng: E kang AISI 316 (DIN 1.4401), e fana ka khanyetso e phahameng khahlanong le mafome, lik'hemik'hale le libaka tse nang le mocheso o phahameng.
3.3 Dibopeho, Meralo, le Dikgokelo
Leha poleloana "ketane ea khokahano e chitja" hangata e hlalosa khokahano ea khale e bōpehileng joaloka oval, moralo ka kakaretso o ka fetoloa bakeng sa mesebetsi e itseng. Mofuta o ikhethang oa moralo ke Ketane ea Lihokelo tse Tharo, e nang le masale a mararo a hokahaneng 'me hangata e sebelisoa bakeng sa ho hokahanya likoloi tsa merafo kapa e le sehokelo sa ho phahamisa merafong le merung. Liketane tsena li ka etsoa li sa sekoa/li entsoe ka mokhoa o se nang sekoaelo bakeng sa matla a maholo kapa e le meralo e kopantsoeng. Lihokelo ka botsona hangata ke lipheletso tsa lihokelo tsa ketane, tse ka hokahanngoang le liketane tse ling kapa lisebelisoa ho sebelisoa li-shackle kapa ka ho hokela masale ka ho toba.
4. Qetello
Liketane tsa lihokelo tse chitjake likarolo tse feto-fetohang le tse matla tsa bohlokoa bakeng sa ts'ebetso e sebetsang hantle ea lifti tsa libakete le li-conveyor tse fapaneng indastering ea lefats'e ea ho sebetsana le thepa e ngata. Li ka khethoa ka nepo bakeng sa ts'ebeliso ho latela boholo ba tsona, boemo ba matla, thepa le likarolo tse ikhethileng tsa moralo. Ho utloisisa karohano ena ho lumella baenjiniere le basebetsi ho netefatsa ts'epahalo ea sistimi, polokeho le tlhahiso. Lintlafatso tsa nakong e tlang li kanna tsa shebana le ho ntlafatsa mahlale a thepa ho ntlafatsa bophelo ba ho tsofala le ho hanyetsa mafome, ho fihlela litlhoko tsa libaka tse thata tsa ts'ebetso.
