Road Roller

Model: CDM5××A
CDM5××A road roller is a mechanically driven and single drum roller. "××" is the weight of the machine (ton). Currently available model is CDM518A, CDM520A and CDM522A. As a compactor type engineering vehicle, CDM5××A road roller can be used to compact soil, gravel, concrete or asphalt in the construction of roads and foundations.

Features of CDM5××A Road Roller:
1. CDM518A, CDM520A and CDM522A road roller use one frequency, two amplitude and close-looped hydraulic vibration system with Rexroth hydraulic components.
2. Being made of high strength material, the drum is wear-resistant and impress-resistant.
3. Wide-view cab and tiltable steering column are designed with ergonomics.
4. Both hand brake and foot brake are available for the safety.
5. Engine hood is opened with manually operated oil cylinder for easy maintenance.
6. Air conditioning and heating system of our road roller provide better environment for operator.
