When we at Junttan set out to design more sustainable innovations, we understood that a new eJunttan model needed to tick all the same boxes from the very beginning as its predecessors. That’s why we decided to combine the best of both worlds; tested and optimized Junttan hydraulics merged with modern batteries and electric motor technology.

The result is the world’s first fully battery-powered electric pile driving rig that is ready to meet the same challenges at the work site as its predecessors. Instead of a diesel engine, we are now powering the hydraulic system with a modern electric motor that generates its power from a battery pack at the rear of the rig where the counterweight used to be. In this way, we were able to build a solution that is reliable, easy to operate, and as effective as normal diesel-powered Junttan rigs. To make everyday life at the worksite possible, we chose a solution where the rig is powered by two separate 396 kWh battery packs that can be replaced during the day if needed. By choosing a detachable two-battery system instead of one bigger fixed, charging can be done with a normal 63A mains outlet, and both batteries are ready the next morning. With the state-of-the-art CCS DC-quick charging, the battery packs can be charged with up to 250 kW to enable even more flexibility and extended range for future worksites also with a single battery pack.
