Road construction equipment specialist Dynapac has launched its first electric paver model, as part of its Z.ERA programme to move towards machines with fossil-free drives.

Described as 鈥渁 glimpse of things to come鈥�, the new eCity SD1800W e wheeled paver has a maximum paving capacity of 350 tonnes an hour and offers a paving width of 4.1m with the screed extended.

It can operate for up to four hours on a single charge, depending on the type of application, and has a paving speed of 25 metres per minute and a top travel speed of 15km an hour.

The eCity SD1800W e features a similar design to that of its diesel powered SD1800W counterpart and, in terms of performance, is suitable for inner-city applications, such as road assignments for bicycle lanes and repair works.

鈥淩ecent developments in e-mobility have shown that the new generation of electric batteries can compete with their conventional, fossil-fuel-run counterparts,鈥� said Dynapac.

鈥淭he SD1800W e is no exception. Its new electric drive comes with a highly efficient 3-phase permanent magnet synchronous motor (PMSM) that provides 55kW of power to the hydraulic system (screed, undercarriage).鈥�

According to the manufacturer, which is set to present the model at the Bauma trade fair in Germany, the eCity machine鈥檚 battery can be charged from 5% up to 80% in three hours using its CE-compliant Type 2 plug for 400V, 6-32A, 1.4 to 22.0kW AC power outlets.

Although 鈥渃harging while working is not possible, one can pre-heat the screed with the charger (with Type 2 AC or CCS2 DC) while waiting for the material to arrive, thus preserving the battery level,鈥� said Dynapac.
