The Hamm PH hybrid power train system for tandem asphalt compactors has been developed to save fuel, costs and maintenance work, benefiting all road construction and maintenance operations.
- System combines the traditional internal combustion engine with a hydraulic accumulator
- The internal combustion engine covers the base load while a hydraulic accumulator meets peak loads
- Results in machines that can be powered with smaller engines, while still delivering the same compaction power
- These smaller engines do not require an SCR catalytic converter or DEF fluid which results in advantages in terms of handling and maintenance
- Quieter power train
- At World of Asphalt Hamm is introducing the hybrid power train system in the HD+ 90i PH tandem roller
