New tandem rollers from Hamm combine vibration and oscillation in one drum
The HD+ series with VIO drum is highly flexible and ideal for new asphalt mixtures
The tandem rollers of the HD+ series have been a firm fixture in the Hamm product range for many years. Hamm is now expanding the HD+ series with the addition of a model capable of compacting with a choice of vibration or oscillation. The new HD+ 120i V-VIO provides an impressive degree of flexibility, alongside the usual high compaction power associated with the brand, and a wide range of options. It has been available in markets with exhaust emission standard EU Stage V/EPA Tier 4f since the start of 2024.
The new HD+ 120i V-VIO 12 t tandem roller featuring a vibration drum at the front and a VIO drum at the rear is powered by a 115 kW Deutz engine. When it comes to compaction force, the new model offers the usual high performance that operators have come to expect from the brand.
High flexibility, fast compaction
Well-known strengths and variety of options
As well as the new combination of drums, the HD+ 120i V-VIO gives users all the usual benefits and strengths they expect of the brand. These include the spacious and clear-view driver's cab, the popular Easy Drive operating concept and various interfaces to connect telematics systems, fleet management systems and digital applications for controlling and documenting compaction.
"Digital ready" in all weight classes
Back in the summer of 2023, new models were launched spanning all weight classes, all featuring the relevant interfaces for digital applications. Plus, the Easy Drive operating concept was also introduced to machines with operating weights of 7 t and 8 t.
Compaction with oscillation
Operators can also make full use of the well-established benefits of oscillation and apply these to the compaction of joints or compaction in vibration-sensitive areas. Oscillation also facilitates deployment at low outside temperatures, since a larger temperature range can be used. Plus, the system is effective in preventing particle crushing and over-compaction. Not to be forgotten are the benefits of oscillation when compacting distortion-sensitive materials. Further general benefits of oscillation are that it reduces the noise emissions and vibrations experienced on and around the construction site.
Maintenance-free oscillation
Another benefit: Like the other oscillation drums from Hamm, the new VIO drums require no maintenance, thanks to the wear-resistant steel and temperature-resistant special belt.
