Fast-Tracked Innovation – Junttan Machine Delivered in 10 Months
Due to deep integration and seamless co-operation with Junttan’s product development team, the machine was designed, manufactured, tested and delivered to the end customer in 10-months from project kickoff.
Electric powertrain conversion for NRMM
The world’s first electric pile driving rig from Junttan is built as the same reliable and strong PMx22 piling rig, but this time with a modern electric soul.
The electric machine includes a swappable battery system for undisturbed, continuous work at site. Due to its built-in on-board battery, the machine can handle swapping its main energy storage (396 kWh Li-ion battery) independently and efficiently without having to shut down during operation. The machine supports both AC (63A) and CCS fast charging where available. The machine can also be run in grid-battery hybrid mode, providing uninterrupted operation with a single battery.
