The Next Level in Electric Pile Driving Rigs
The Junttan PMx4e is unlocking the capabilities of larger electric pile driving rigs. Junttan took a pioneering stride towards a sustainable future by introducing the world’s first fully battery-powered electric pile driving rig in 2021. The Junttan PMx4e retains the reliable and robust design of the Junttan PMx24 piling rig while embodying a contemporary electric essence. Maintaining its sturdy structure and unparalleled stability, this innovative rig stands out for producing zero local CO2 emissions. It operates at the same efficient speed and reliability while consuming less energy. Additionally, it boasts increased power while minimizing noise pollution.

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 beginning as its predecessors. That’s why we combined 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 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 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 standard 63A mains outlet, and both batteries are ready the next morning.
Optional features include:
– a plug-in mode for extended working time
– an onboard battery for easy battery pack change and transportation
With the state-of-the-art CCS DC-quick charging, the battery packs can be charged up to 250 kW, enabling even more flexibility and extended range for future worksites with a single battery pack.
