Kev faib tawm los ntawm Cov Menyuam Yaus: Kev tsim cov menyuam yaus suav nrog cov menyuam yaus du, grooved rollers, thiab yaj tus ko taw rollers. Smooth rollers yog siv dav tshaj plaws, feem ntau yog rau compacting txoj kev nto txheej txheej. Lawv ntiav cov neeg kho tshuab lossis hydraulic kis tau tus mob, ua kom muaj zog rau cov khoom sib txuas ua ke, ua rau muaj kev sib zog ua kom zoo, haum rau asphalt pavement compaction.
Kev faib tawm los ntawm Qag Arrangement: Raws li kev teeb tsa qag, muaj ib qho - qag ib zaug - lub log, ob - qag ob - lub log, ob npaug - qag peb - lub log, thiab peb - qag peb - lub log. Lawv yog powered los ntawm internal combustion engines thiab ntiav mechanical los yog hydraulic kis tau tus mob. Feem ntau, lawv muaj pem hauv ntej - lub log tsav kom zoo maneuverability thiab rear - lub log tsav. Txhawm rau txhim kho kev tsav tsheb thiab kev ua haujlwm kom zoo, cov qauv kev taw qhia qhia tau zoo thiab tag nrho - lub log tsav raug pom zoo. Lub log pem hauv ntej thiab lub chassis tau hais kom txo cov tshuab sway thaum txoj kev tsis sib xws. Lub log tsheb thiab chassis yog sib txuas nruj heev. Hydraulic ua haujlwm yog siv, nrog kev tswj xyuas los ntawm hydraulic kheej kheej. Ob leeg pem hauv ntej thiab nram qab rollers yog nruab nrog scrapers kom tshem tawm cov ntaub ntawv adhering. Lub tshuab tua dej kuj tau teeb tsa los tua cov dej ntawm cov menyuam thaum lub sij hawm asphalt pavement compaction los tiv thaiv asphalt sib tov adhesion. Txhawm rau kom muaj zog, hlau, xuab zeb, dej, thiab lwm yam tuaj yeem muab ntxiv rau hauv kev sib tsoo log kom nce qhov hnyav.
