Road Roller

Model: CDM5××D
DM5××D road roller is hydrostatic and double (front & rear) driven single drum roller. "××" stands for the weight of the machine (ton). Currently available models are CDM512D, CDM518D and CDM520D. As an engineering vehicle/ engineering equipment, this road roller is suitable for compacting soil, gravel, concrete or asphalt in the construction of roads and foundations.

Features of CDM5××D Road Roller:
1. Cummins supercharged diesel engine made in China with excellent powerman margin and fuel economy.
2. Front and rear wheel drive of this road roller is with closed-loop hydraulic system, four speeds with stepless gear change, strong grade ability
3. Closed-loop hydraulic vibration system with frequency change and amplitude modulation; linear load and exciting force are optimized;
4. Drum of this road roller is made of high strength material which is wear-resistant and impress-resistant
5. Wide-view cab and easily accessible control mechanism designed with ergonomics
6. Brake systems on front and rear wheels are with cut-off device for better safety
7. Engine hood is opened with manually operated oil cylinder for easy maintenance
8. Air conditioning and heating system provide better environment for operator.
