Single Drum Soil Rollers
Self-propelled rollers with one vibrating drum and a driven rear axle, used for subgrade, capping and thick granular lifts. Padfoot versions handle cohesive soils that a smooth drum only shears.
Features
- Smooth drums compact granular fill and sub-base; padfoot drums knead cohesive soil and leave a keyed surface for the next lift.
- Two amplitude settings let one machine work a deep lift and then finish it without a second roller.
- Drum drive, as opposed to rear-axle drive only, is what gets the machine up a soft ramp and across a fresh lift.
- Compaction measurement systems read drum response and map coverage, which is how a layer is signed off without a test pit on every grid square.
- Cab isolation and a suspended seat matter, because this machine runs eight hours of continuous vibration.
Specifications
| Figure | Typical range | Unit | Why it matters |
|---|---|---|---|
| Operating weight | 7 000 - 26 000 | kg | Sets lift thickness and the ground it can work without bogging. |
| Drum width | 1 700 - 2 200 | mm | Decides passes per lane of formation. |
| Centrifugal force, high / low | 250 / 170 | kN | The two working settings for deep lift and surface finish. |
| Amplitude, high / low | 1,90 / 0,95 | mm | Governs the depth of influence in the layer. |
| Gradeability with vibration | 40 - 55 | % | Decides whether the machine can compact an embankment slope. |
