HAMM, a compaction specialist which is part of the Germany-based Wirtgen Group, recently introduced its latest battery-powered tandem rollers, stepping up efforts to eliminate operating emissions from road construction machinery.

The new pivot-steered HX 70e VV-S, a fully electric roller with two vibration drums, is designed for use on inner-city construction sites, where reducing noise and exhaust emissions is becoming a regulatory requirement. A second variant, the HX 70e VO-S, uses an oscillation drum and will also be introduced as a sales variant.

Powered by a 400-volt, 63 kWh lithium-ion battery developed with Austria's Kreisel, the HX 70e can be charged via a Type 2 connector, with additional compatibility for Type 1, J1772, and CCS charging systems planned. With fast charging, the battery can be replenished from 20 per cent to 80 per cent in under an hour.
