Electric rollers: Zero-emission and quiet compaction

Demand for low-emission or even zero-emission construction machines keeps growing. And the road construction and earthworks sector is no exception to this trend. HAMM has factored this into its product development, enabling customers around the world to benefit from quiet and emission-free compaction with electric rollers.

Drive and key components

HD 10e – HD 12e: Highlights

Watch the video to find out more about the key features and benefits of the new, fully-electric HD 10e – HD12e.

The power train at a glance

Diagram of power train. Focus on front left: The 23.4 kWh battery, which is built into the machine, can be charged via standard charging as well as fast charging. What's more, the battery requires no maintenance and has an integrated and safe battery management system.

The current flow

The blue arrows indicate the flow of current that drives all components, including a drive motor, a steering motor, and two vibration motors.

Energy recuperation

Energy is recovered from the drive motor and vibration motor. The green arrows represent the flow of energy during recuperation.

The benefits at a glance:
  • 100% electric drive, no local emissions
  • Maximum compaction power
  • Maximum efficiency for high battery runtimes and long operating times
  • Enough energy for a typical working day
  • Reduced noise emissions
  • Operation identical to the diesel machine
  • HAMMTRONIC: Drive computer, ECO mode, convenient and smooth control of the driving speed using electric driving lever, auto machine off
  • Maintenance-free electronic components (battery, e-motors, inverter, DC-DC converter)
  • Optimal use of energy for long operating times
  • Energy recuperation
  • 70% less hydraulic oil
