Resource-conserving power train
In all current series, the power train has been continuously optimised and designed for operation at reduced speeds. The operating companies therefore save fuel each day. The automatic engine stop also reduces consumption: It automatically switches off the engine after a few minutes of downtime, while also taking into consideration the requirements for the exhaust gas cleaning systems. The ECO mode, which is integrated into all series, also helps the driver to compact in a way that they can easily save fuel.
Quiet Power Hybrid rollers save CO2
Back in 2016, HAMM was already the first manufacturer in the world to combine a diesel engine with a hydraulic accumulator for the development of alternative drives. With this Power Hybrid roller from the HD+ series, it was possible to reduce the fuel expenditure by approx. 15% – all without having to compromise on compaction power. This was also coupled with a reduction in noise emissions.
Emission-free compaction with electric tandem rollers
More and more municipalities are demanding low-emission or completely emission-free construction machines. In future, wherever compaction must be carried out free of emissions, the electrically powered tandem rollers in the HD CompactLine series can take over the compaction. When operating the electric tandem rollers, there are no differences to the diesel-powered models, and even the compaction power is identical.
Fully electrical solution
Conceptually, HAMM is relying on a fully electric solution: Thanks to a high degree of electrified components, the compaction specialists achieve an optimal energy yield. A maintenance-free Li-ion battery with a capacity of approx. 23 kWh supplies the components via a 48 V on-board power supply. Furthermore, the energy released from the drive engines and vibration motors when braking is used via recuperation. The bottom line is that the battery can be used to tackle an entire working day. To charge the permanently installed battery, plugs for 230 V and 400 V mains power are included on-board.
