CONEXPO PREVIEW: Volvo Construction Equipment (Volvo CE) is unveiling its latest addition to its growing portfolio of electric machines – and its first for the road segment – with the DD25 Electric asphalt compactor.
A compact double-drum asphalt compactor, the DD25 Electric is a zero-exhaust emission solution for small scale compaction projects including street repairs and patching, parking lots, driveways.
The electric driveline of the DD25 Electric is based upon the same architecture and components found on Volvo CE’s ECR25 Electric compact excavator and L25 Electric compact wheel loader.
Expected to operate for a full shift on a single charge depending upon the type of job and intensity of the work cycle, the DD25 Electric has the same charging solutions as the ECR25 Electric and L25 Electric. The machine comes with an integrated on-board charger which enables charging from 0 to 100 percent in as little as three hours depending on AC power level. With an optional off-board DC fast charger, this can be achieved in little over an hour, and this also offers a practical solution to top-up the machine’s charge during the lunch break.
The DD25 Electric offers 24 kW of available power, 30 percent more than the conventional Volvo DD25B. The result is a more responsive machine in terms of speed and vibrations, which performs better on grade, thanks to the size of its components, and better at high elevations, when compared to a diesel machine which loses power as you increase altitude.
360-degree visibility and high frequency compaction allow operators to achieve a smooth finish asphalt surface with speed. Frequency can be adjusted from 3500 vpm / 55 Hz to 4000 vpm / 67 Hz to cater for different applications.
