Electric rollers

With electric rollers, HAMM is responding to the growing demand for alternative drive technologies in road construction and earthworks. The machines enable compaction without local exhaust emissions at the site and are characterised by their quiet operation.

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 the power train. Focus on front left: The 23.4 kWh battery, which is built into the machine and allows for 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:
  • Purely electric drive; local emission-free
  • Efficient energy management for high battery runtimes and long operating times
  • Reduced noise emissions when compared to a conventional diesel-powered machine
  • 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, electric motors, inverter, DC-DC converter)
  • Efficient use of the available energy to support long operating times
  • Energy recuperation
  • Reduced hydraulic oil requirement when compared to equivalent conventional models (depending on the model)
