Mofani oa lisebelisoa tsa kaho oa litharollo tsa mechini ea kaho ka lilemo tse 30.
Mochini o na le poleiti e boima ea tšepe e bataletseng tlase. Enjene e nyane ea peterole kapa diesel e potoloha boima bo sa keneleng bohareng kahare, e leng se etsang hore ho be le ho thothomela ho matla ho ea holimo le tlase. Ho thothomela hona, hammoho le boima ba mochini, ho sutumelletsa likaroloana tsa mobu haufi le ho tlosa likheo tsa moea. Mefuta e mengata ea thothomela pakeng tsa makhetlo a 4000 le 5800 ka motsotso, 'me matla ao ba a hlahisang a lekanngoa ka li-kilonewtons (kN). Matla a phahameng a bolela ho teteana ho tebileng ka ho palama hanngoe.
Boholo bo fapaneng ba poleiti le bona bo fetola tsela eo mochini o itšoarang ka eona. Lipoleiti tse tšesaane (tse bophara ba lisenthimithara tse ka bang 35–50) li fihla likhutlong tse thata hantle, ha lipoleiti tse pharaletseng (ho fihlela ho lisenthimithara tse 67) li koahela mobu o mongata kapele. Lithapo tsa rabara tse monyang li thibela boholo ba ho sisinyeha hole le matsoho a motho ea sebetsang kahoo mosebetsi o ikutloa o sa khathale haholo.
Borakonteraka ba sebelisa li-compactor tsa lipoleiti tse thothomelang bakeng sa mesebetsi e mengata ea letsatsi le letsatsi. Ba lokisa metheo tlas'a litsela tsa lirapa, litsela tsa ho kena, mathule le litokiso tse nyane tsa litsela. Lehlabathe le lehlohlojane li arabela hantle hobane ho thothomela ho thusa lithollo ho hokahana ka thata. Metsoako ea konkreite e omileng e nang le majoe a manyane le eona e kopana hantle bakeng sa litšiea le li-slab.
Bakeng sa mosebetsi oa asphalt boemo boa fetoha. Asphalt e chesang kapa e batang e khomarela poleiting e omileng 'me e etsa libaka tse sa lekanang. Ke ka lebaka leo mehlala e nang le tanka ea metsi e hahiloeng ka hare e fafatsang filimi e tšesaane ea metsi ho emisa ho khomarela le ho fokotsa lerōle ka nako e le 'ngoe.
Mehlala e shebaneng le tsela e le 'ngoe e ea pele feela. E bobebe (hangata e boima ba 65-120 kg) 'me e bonolo ho e jara ka li-handle tse menoang kapa mabili a manyane. Tsena li loketse libaka tse bulehileng tse bataletseng tse kang litsela tsa ho kena kapa ho lokisa jareteng moo u ka tsamaeang ka mela e otlolohileng.
Di-compactor tsa poleiti tse ka kgutliswang di tsamaya pele le morao, mme tse ngata di ka thothomela sebakeng se le seng. Sena se boloka nako e ngata diforong tse moqotetsane, maboteng, ho potoloha metheo kapa dibakeng tse thata tsa ho tlatsa moo ho leng thata ho phetla mochini ka letsoho. Diyuniti tse boima tse ka kgutliswang (125–330 kg) di fana ka matla a matla (25–38 kN) mme di fihlella botebo ba ho teteana ho fihla ho 90 cm, e leng se etsang hore e be kgetho e ntle bakeng sa mosebetsi o tebileng kapa o kwalletsweng.
Kamehla qala ka botenya bo nepahetseng ba thepa. Jala mobu kapa lehlohlojane ka mekhahlelo e seng metenya ho feta kamoo mochini o ka sebetsanang le oona (hangata 20-40 cm ho latela matla). Etsa hore ho be le mekhahlelo e meraro kapa e mene e fetang holim'a lera ka leng ha u ntse u tsamaea ka lebelo le tsitsitseng.
Lekola mongobo mobung pele. Lehlohlojane le lesesaane le metsi haholo le ka etsa hore poleiti e thekesele 'me e hane ho tsamaea hantle. Bakeng sa sekontiri, bula valve ea tanka ea metsi 'me u boloke tanka e tletse. Ntle le metsi poleiti e hula 'me e siea matheba a mabe.
Roala liatlana, tšireletso ea litsebe le lieta tse matla nako le nako. Kamora ho qeta, hloekisa seretse le majoe poleiting le foreimi e le hore ho se ke ha e-ba le letho le thatafalang le bakang mathata nakong e tlang.
Molemo o moholo ke ntlafatso e potlakileng le e tšepahalang ea mobu e emisang ho rarolla mathata nakong e tlang. Mehlala e ka fetoloang e qeta mesebetsi kapele libakeng tse thata 'me e fokotsa boiteko ba mosebelisi. Lipoleiti tse sephara le matla a phahameng a centrifugal li eketsa tlhahiso ea letsatsi le letsatsi, ka linako tse ling e fihla ho lisekoere-mithara tse 500–650 ka hora.
Ho kgetha mochini o nepahetseng le hona ho boloka tjhelete. Mohlala o tsamaellanang le mofuta wa mobu, botebo bo hlokahalang le boholo ba sebaka o qoba ho feta ha metsi a feta, tshenyo ya mafura le ho lokisa dintho botjha. Dikarolo tse kang diswitjhi tsa tshireletso ya oli le dipoleiti tsa motheo tse tshwarellang di boloka ditokiso di le tlase ho theosa le dilemo tsa tshebediso.
Sheba liboutu tsohle ka mor'a mosebetsi o mong le o mong 'me u tiise leha e le efe e ikutloang e lokolohile. Lithako tse hlephileng li fokotsa matla 'me li ka roba likarolo tse turang. Fetola oli ea enjene ka mor'a libeke tse peli tsa pele tsa tšebeliso, ebe likhoeli tse ling le tse ling tse tharo ho isa ho tse hlano.
Maemong a lerōle hloekisa kapa u nkele sefe ea moea sebaka khafetsa. Haeba enjene e sa qale, hlahloba peterole, polaka ea spark le carburetor pele - mathata a mangata a tsoa libakeng tsena tse tharo.
Sekoahelo sa poleiti se hlokometsoeng hantle se fana ka ts'ebetso e tsitsitseng lehlabatheng, lehlohlojane, mobu o tsoakiloeng le asphalt. Ho bapisa matla a centrifugal, bophara ba poleiti, mofuta oa tataiso le tanka ea metsi le maemo a hau a sebele a ts'ebetso ho fana ka lebelo le letle ka ho fetisisa, boleng ba ho qeta le boleng ba nako e telele morerong o mong le o mong.
