New at HAMM: Tandem rollers with electric drive
Particular focus is placed on the electric tandem rollers in the HD CompactLine series, which is used across the world. They compact with zero local emissions and are also extremely quiet. The operation and the compaction parameters are identical to the diesel-driven machines. The completely battery-powered rollers can work for an entire typical work day with the Li-ion battery (capacity 23 kWh) without needing to be charged. The rollers are expected to be available in the USA from the end of 2023.
North American premiere for earthworks: Compactors in the HC series
With the HC series, HAMM is bringing together all compactors with an operating weight of 24,251–55,116 lbs (11–25 t) on a single platform. The engine power levels are between 85 and 160 kW; their emissions comply with the respective regional requirements. Thanks to an integrated ECO-Mode, the rollers work in the economical partial-load range for most of the time. With over 20% increased tread, around 30% increased space, and more storage compartments, the Easy Drive cabs are more comfortable than ever. Many options are available for all models – from the automatic engine stop through to the dozer blade. Thanks to numerous interfaces, the compactors in the HC series are "digital-ready", in other words, they are ready to be used in an extremely wide range of tools, including the Smart Doc app. In addition to the variants that were hitherto available on the market, in the future, there will also be CR machines with specially reinforced equipment for use on rocky ground and on difficult terrain.
HC CompactLine series – another premiere for North America
In the segment for small compactors (11,023–15,432 lbs, 5–7 t), HAMM is showcasing the HC CompactLine series. In contrast to the predecessor models, HAMM has further improved the driving comfort, and has increased the traction and gradeability. The HC 70i model is still the most compact roller in the 7 t class on the market. Various digital tools are available for all HC CompactLine models, in particular the Smart Doc app. It supports GNSS-based self-monitoring and documentation.
Smart Doc: Digital assistant for compaction
The free Smart Doc app shows in real-time how the compaction develops, and links the machine data to GNSS position data. The app creates clear compaction results in PDF format. They are suitable for self-monitoring as well as for documentation with respect to clients. No separate monitor is required to operate the app. It works simply via standard Android smartphones or tablets. In the 2023 asphalt season, M2M (machine to machine) communication and M2C (machine to cloud) communication will also play a role.
