Dynapac launches first electric paver
By Leila Steed18 October 2022
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 “a glimpse of things to come”, 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.
“Recent developments in e-mobility have shown that the new generation of electric batteries can compete with their conventional, fossil-fuel-run counterparts,” said Dynapac.
“The 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).”
According to the manufacturer, which is set to present the model at the Bauma trade fair in Germany, the eCity machine’s 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 “charging 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,” said Dynapac.
