U-Road Roller ephambili yomsebenzi wokuphakama, usebenzisa ubukhulu nabangqi ukuletha imiphumo engaqondisi ngemisebenzi esemqoka. Isimo sakho sokuthengwa sibekwe kumatolobe amathathu: yalo Ukuphressa Okuphezulu Okungahlonipha , yayo I-Center of Gravity Ephezulu kweqiniso lokuphakama , futhi Hydrostatic Transmission nge Umoya Wokuhamba Oyinto Ekuwakhiweyo .
U Ukuphressa Okuphezulu Okungahlonipha yindlela yokulinganisa ngokuphelele umehluko wobusha. Le nqubo, okuyindlela yokubala ubukhulu beqondo elijwayelekileyo ngokwahlukaniswa kwegama le mpilo ngobude be drum, yindlela yokulinganisa ngokuphelele isebenzisa kumakhi. Ngaphambi kokuthi kuvule kumele kube khona, le nqubo isebenza ngokuphelele ukuthi i-compaction ikhulume, i-settle kumakhi futhi ikhombise isicaba esemgceni sokuqala. Umehluko obusha uthatha ngeke kube ngaphezulu kwe nqubo ejwayelekile, lokhu kuvumela ukuthi uthathe izindleko ezinkulu futhi kumakhi okuningi. Lokhu kuyindlela yokuthi i-"breakdown" ikhulume ngokuphelele ngokuthi i-asphalt paving, lapho isibonelo ukuthi sikhuthaze isiqephu esingu- target density ngokushesha noma kumele kube sele kuvule futhi kusebenza. Le nqubo yokubusa i-linear ikhombisa ukuthi kube yimali ngokuphelele ngale ndawo ebalulekileyo.
Ukuze usebenzise ngokuphelele le nqubo, i I-Center of Gravity Ephezulu kweqiniso lokuphakama yindlela esenza ngokubaluleke kakhulu. Izinto ezinhleke—the engine, izimpumpu zohhamu, ne-drum—ziqoshwe phansi kakhulu ngaphakathi kwe-chassis yomakhine. Le ndlela isenza ukuba kube lula ukuba yindlela esenza ngokubaluleke kakhulu. Le ndlela isenza ukuba kube lula ukuba kube yinto ephahla ngokuphahla, okuyindlela esenza ngokubaluleke kakhulu kwezinye izinhlobo zeqine zokusebenza kuzo izindlebe, izindawo ezikhulu, nezindawo ezingeziflat. I-centre of gravity ephantsi, ngemva koko noma kuthiwa ngokubaluleke kakhulu, ikuvumela ukuba le roller iqine izindlebe nezisebenze ngemoya oqinile lapho enye into engenakusebenza ngokuphahla. Le ndlela esenza ngokubaluleke kakhulu ikuvumela ukuba inkinobho yeqine yomakhine yindlela esenza ngokubaluleke kakhulu, ngaphandle kokuthi umsebenzisi abe ngokuthula kakhulu noma abe ngokuthula kakhulu, ngakho ke ikuvumela ukuba kube yinto ephahla ngokuphahla ukuphathwa okuphelele kwekhipha kuzo zonke izindawo zeqine.
Ukuhlanganisa nekuhlela kwezinhlobo ezinhleke kakhulu kwezinto ezinhleke kuyadinga Hydrostatic Transmission .
Le ndlela ikuvumela Umoya Wokuhamba Oyinto Ekuwakhiweyo , okuyindlela esenza ngayo ngokuphezulu. Into yokusebenzela iyakhetwa ngokushesha okudingekayo yokunciphisa ngokuphezulu, kusukela ekushesheni kakhulu ngokunciphisa ngokuphezulu kumaqo athintekayo kuye nokushesha okupelene nokulayisha kwezindawo ezinciphiswe ngaphambili. Akukho amagiyela okuthayela, okunxibekela ukuthi ukushisa kanye nokulula kuhamba ngaphansi kungakhathaliseki, okungaba yindlela yokulahla umgqa wendawo entsha. I-hydrostatic drive inikeza i-torque ephakeme kumaqo amancane, inikeza amandla okuthi ukutholwa kwezindlebe ngaphansi kwegama elilodwa ngekuba yisale. Le nto yokukhawuleza ukushesha kohamba, ngokwengeza kwezinye izinketho zokuvukela, kwenza into yokusebenzela ukuthi ikhuthaze ukunciphisa ngokweminye imithwana kanye nezibopho, ukunikezela ukuchithwa okuchanekileyo kutheniwe ngokuphezulu kanye nezinye izindawo zemgqa.
