Iloli yokusasaza irabha ekrelekrele yitanki yohlobo lwesithuthi esikhethekileyo esixhotyiswe ngesitya esigqunyiweyo, impompo yebhitumene, isifudumezi kunye nenkqubo yokutshiza yokutshiza ibhitumene. Isetyenziswa kakhulu kulwakhiwo lweendlela ezifana nohola wendlela, iindlela zasezidolophini, izikhululo zeenqwelo moya, amazibuko kunye namadama. Ngenkqubo yolawulo olukrelekrele, uyilo oluphambili, olujoliswe kumsebenzisi, iqondo eliphezulu lokuzisebenzela, uhlengahlengiso oluzenzekelayo lokuhamba kwebhitumene.

Ulungelelwaniso oluneenkcukacha lwelori yokusasaza irabha ekrelekrele:
Impompo ye-hydraulic, impompo yebhitumene, i-bitumen pump drive motor, isitshisi, isilawuli sobushushu, kunye nenkqubo yokulawula isithuthi zonke ziphuma kumazwe angaphandle okanye amacandelo e-brand adumileyo, athembekileyo ekusebenzeni; Yonke inkqubo yokutshiza ilawulwa yikhompyutheni, ngokwemeko yokwakha, unokukhetha indlela yokutshiza ngokuzenzekelayo kwikhompyutheni yombhobho ongasemva, okanye indlela yokutshiza nge-nozzle ebanjwe ngesandla, efanelekileyo kwaye inokwethenjelwa ukusebenza; Ukulungelelanisa ngokuzenzekelayo isixa sokutshiza ngokokutshintsha kwesantya sokuqhuba isithuthi; I-nozzle nganye ilawulwa ngabanye, kwaye ububanzi bokusabalalisa bunokulungiswa ngokungaqhelekanga; Ukuxhotyiswa ngeeseti ezimbini zeenkqubo zokulawula (i-cab, i-platform yokusebenza yangasemva), ukurekhoda kwexesha langempela lendawo yokutshiza ibhitumene, umgama wokutshiza, ukutshiza inani elipheleleyo, ukuqinisekisa ukuthembeka kokutshiza kwebhitumene; Inkqubo yokulawula ekrelekrele, kufuneka kuphela ukuseta isixa sebhitumenspraying ngemitha yesikwere, inokuqonda ukutshiza ngokuzenzekelayo; Isithuthi sonke sixhotyiswe ngezixhobo zokuzilungisa kunye nokudlulisa izixhobo; I-oyile yokuqhuba ubushushu ifudumeza kwaye ikhusela amatanki, iimpompo zebhitumene, imilomo, imiqadi yokutshiza, kunye nemibhobho yebhitumene ngendlela ejikelezayo ukuhlangabezana neemfuno zeentlobo ezahlukeneyo zokwakha ibhitumene; Imibhobho kunye nemibhobho ihlanjululwa ngomoya ophezulu woxinzelelo, kwaye imibhobho kunye nemibhobho ayilula ukuvalelwa. Ukutshiza kuyasebenza kwaye kulula, kwaye ukusebenza okusebenzayo kukhuselekile kwaye kuthembekile.

Izibonelelo ezikhethekileyo zelori yokusasaza irabha ekrelekrele:
1. Itanki ye-bitumen yerabha ixhotyiswe ngesixhobo esinamandla sokuvuselela ukunyanzela ukuhanjiswa kwendawo ephakathi kwitanki ukuphepha ukwahlukana kwebhitumene kunye nemvula, kwaye iyakwazi ukulungelelanisa ukufudumeza kunye nokusabalalisa kwebhitumene eyahlukeneyo;
2. Itekhnoloji eyomeleleyo yokulawula isitshizi inokuqonda ukuqala kokutshiza komgama ongekho mgama, ukutshiza okufanayo kunye nokuthembekileyo;
3. Isithuthi sinokuxhotyiswa nge-manual spray gun ukutshiza i-bitumen yendawo kwiikona kunye neengxenye ezikhethekileyo ukuhlangabezana neemfuno zeemeko ezikhethekileyo zokusebenza.
4. I-chassis ikhethwe kwi-chassis eyaziwayo yemoto yasekhaya, enamandla anamandla, amandla okuthwala anamandla, ukuqhuba kakuhle, ukusebenza okuzinzileyo kunye nokusebenza kakuhle.
