Road Roller

Model: CDM512DD
CDM512DD road roller is a hydrostatic tandem vibratory roller. As a type of engineering vehicle, this road roller can be used for compacting various stabilizing material, asphalt concrete, dry concrete, as well as road bed.

Features of CDM512DD Road Roller:
1. Original Cummins supercharged engine 4BTAA3.9C and Rexroth hydraulic components.
2. Hydrostatic front and rear drives, stepless gear change, easy operation
3. Both front and rear drums of this road roller vibrate with frequency change and amplitude modulation, work in high efficiency.
4. Crab steering of maximum 170mm for better edge compaction.
5. 180° multi-position rotary platform for easy observation of edge compaction.
6. Road roller front and rear brakes with cutoff device for better safety.
7. Two independent watering systems with imported pumps and big water tank.
8. Air conditioning and heating system provide good environment for operator.
