Ingersoll Rand Vibratory Smooth Drum Roller

Extra letters such as the "S" in DD10S mark variants within a size class; when in doubt, the nameplate or that specific model's manual is the reliable source, since SpecCodex does not carry a confirmed meaning for the addition.

The bucket's 40 live-listed models show the spread: engine output 12 to 152 kW, operating weight 1,317 to 20,411 kg — everything from a handy trench roller to a heavy tandem roller for road building.

For a used vibratory roller, drum condition matters most: out-of-round drums, dents, and cracks on the running surface permanently reduce compaction quality. Add a function test of the vibration system (exciter, bearings), a check of the drum water-spray system on asphalt rollers, and a comparison of recorded hours against visible wear.

In short: DD means double drum, the following number is the weight class. When choosing between close numbers like DD24 and DD29, compare operating weight and drum width directly rather than relying on the model number alone.
