（1） Features
Hydraulic double wheel drive vibratory roller is manufactured according to the international advanced technology and by use of imported components from abroad. The machine is super heavy-dutyvibratory roller, possesses a great working mass and strong centrifugal force. It is the best compaction equipment of high quality and high effect in the large-scale mechanized construction. this machine is suitable for non-cohesive materials, such as graves, macadam, macadam-aggregate mixtures and sandy soil etc. Also it can be a good effect compaction in cohesive material, There fore the machine an ideal equipment for expressway. mining road, embankment, seaport and industrial sites.
Power System: CUMMINS B-series turbo-charged diesel engine, huge power man coeffciency, complicable for the operating condition above 4000 meters altitude.
Total hydraulic pressure, total drive, frequency and radiation conversion, articulated direction change, two stepless speed changes, advanced technology; Blocking the oil supply to brake the vehicle, safe and reliable.
Streamline outline, circular windshield glass and curvy hood form a unique style.
