Txoj kev cov menyuam yog cov cuab yeej tshwj xeeb siv rau kev tsim thiab compacting txoj kev, railways, tshav dav hlau teb, embankments, water conservancy engineering foundations thiab lwm yam dej num.Hauv kev tsim kho txoj kev, txoj kev rollers yog ib qho ntawm cov khoom siv tseem ceeb.22-tuj txoj kev cov menyuam yog ib yam ntawm cov menyuam yaus txoj kev nruab nrab, uas muaj qhov loj me me thiab compaction dav, thiab ua lub luag haujlwm tseem ceeb hauv kev tsim kho.
1. Mechanical tsav, plaub ceev;hydraulic vibration (vibration tshuab), pem hauv ntej log hydraulic vibration los yog vibration (vibration oscillator) phau ntawv pib-up;hydraulic steering, ua haujlwm yooj yim
2. Oscillation thiab vibration zog yog hloov manually, uas yooj yim rau kev khiav lag luam thiab tsis muaj kev cuam tshuam (kev co oscillator)
3. Articulated ncej, hloov tau lub kauj;pem hauv ntej ncej diav rawg kev txhawb nqa tsim, tuaj yeem nyob ze ntawm txoj kev lub xub pwg nyom rau compaction;tag nrho lub tshuab muaj qhov zoo nkauj zoo nkauj
4. Ob lub tis ntawm lub nraub qaum tuaj yeem qhib ntawm 180 degrees, uas yooj yim rau kev tu lub cav.
5. Hluav taws xob tswj lub siab txau dej, tiv thaiv corrosion sprinkler tank thiab system
6. Xaiv cov log tsheb du lossis treaded tsav tsheb
7. Hom toj siab tuaj yeem nruab nrog lub tshuab hluav taws xob supercharged
Scope ntawm kev siv:
Compaction thiab kho ntawm cov pavement foundations thiab asphalt nto xws li hauv nroog txoj kev, intercity thiab county thiab township txoj kev, kev ua si thiab lwm qhov chaw muaj.
Vibratory vibratory rollers yog tsim nyog rau compaction thiab kho asphalt nto txheej xws li choj decks qhov kev co compaction tsis haum.
