With the latest engine technology and features that help to provide a dense, high-quality mat, the Volvo CE CR30B and CR35B are developed for small-scale compaction projects.
Built on the platform of previous models, the next-generation machines can be used in a variety of applications, such as driveways, small paths, patchworks or shoulders on roads.
The rollers use the high-frequency vibration of the front drum to achieve density targets, and the four pneumatic rear tires manipulate the compacted material, ensuring impermeability and smoothness of the mat.
Both Volvo CE models are powered by a Kubota 49.6 hp low-emission, fuel-efficient engine, which meet Tier 4 Final emissions regulations and feature a passive regeneration system that cleans the filters automatically.
The filter cleaning capability eliminates the need for the machine to stop or for operator input. Fuel use is also reduced via the optional auto-idle feature, which reduces engine speed when controls are inactive for more than 60 seconds.

The Volvo CE CR30B and CR35B combination rollers offer consistent compaction due to a handful of advanced features, according to Volvo. The auto-vibration feature automatically engages vibration when the machine reaches 2.4 km/h and disengages when the speed drops below 1.9 km/h to reduce the risk of over-compaction.
To optimize finished pavement quality, the drum edges are chamfered and rounded to avoid marking the mat while rolling.
The pressurized water spraying system and a separate emulsion tank prevent material pick-up. As well, the operator can adjust the water flow rate and emulsion flow rate independently, for greater productivity and ease of use.
Ease of operation is enhanced by the new side console and display, enabling operators to make adjustments on the fly.
The operator seat can also slide laterally according to individual preferences and jobsite requirements.
For increased rolling precision, the engine hood is sloped, offering a clear forward view of the jobsite, as well as unobstructed sightlines down to the drum and spray bars.
For improved uptime, Volvo CE included a 300 litre water spraying system increases time between refills, while the low positioning of the water and emulsion tanks enable them to be quickly and easily filled from ground level.
The machines’ hinged hood provides clear access to the engine, hydraulics, fuses and relays for swift and convenient servicing.
Volvo also offers a range of solutions to optimize machine uptime and reduce operating costs.
The CR30B and CR35B are Tech Tool and MATRIS compatible, helping speed up diagnostic time.
