Presentation

Digitalization, electrification & efficiency – a shorter route to zero for excavators

In this session, we will share details about the UK field trial of three 20ton excavators fitted with the Dextreme system. And how by increasing the efficiency of the hydraulic system, excavators can deliver the same amount of work with a smaller engine and less fuel – or do more work with the same size engine. For battery electric excavators, Dextreme systems enable OEMs to reduce the battery capacity, thereby reducing the cost of the main battery and enabling more cost-effective electrification. We will show that, depending on system complexity and duty cycle, a reduction in energy requirement of up to 25% can be achieved.
