Danfoss Helps Junttan Deliver the First Fully Electric Pile Driving Rig

Danfoss’ Editron division has collaborated with Junttan, the leading manufacturer of hydraulic pile driving rigs, to help deliver the world’s first battery-powered, fully-electric pile driving rig. The hydraulic system of the first eJunttan, PMx2e, is controlled by an Editron electric motor that generates power from a battery pack.

According to recent research, emissions from the construction industry reached their highest ever level in 2019. Currently, the sector is responsible for 39% of all CO2 emissions globally. With international agreements such as the Glasgow Climate Pact in place to reduce emissions and reach net-zero, the construction industry faces the significant challenge of decarbonizing quickly. This means that there is a huge demand for manufacturers to bring zero-emission construction products and machines to the market.

The PMx2e has been designed to match the operational performance of a diesel-powered rig as closely as possible, even in the harshest working environments. The result is a machine that offers the same robust structure and usability as a traditional pile driving rig, while providing more power and instant torque. In addition to consuming less energy per pile and producing less noise, the PMx2e emits zero emissions while in operation.

Junttan chose Danfoss’ Editron division to supply its PMI375-T1100 series motor after being impressed with its portfolio of sophisticated electric drivetrain systems. The company’s software-led approach delivers maximum efficiencies and offers freedom of design due to being lightweight and compact. Danfoss’ experts are also offering technical support to Junttan in selecting drive components for the machine.

“This new, electric pile driving rig demonstrates our commitment to helping our customers build a more sustainable future around the world," said Pasi Poranen, Junttan's CEO. "After four years of research and development, we’re bringing the future replacement of a diesel engine deep foundation machine to the market. PMx2e will empower our clients by massively reducing their CO2 emissions and environmental footprint.”

“Working with Junttan to help create the world’s first fully-electric pile driving rig is a real privilege for us," said Antti Väyrynen, director of off-highway of Danfoss’ Editron division. "At Editron, we’re committed to delivering the technology to enable a carbon-free future, including leading the way towards a sustainable construction industry.”

The PMx2e electric pile driving rig was commissioned by Per Aarsleff A/S, one of Europe’s premier contracting firms, and its Swedish subsidiary Aarsleff Ground Engineering AB. It is expected that the machine will enter series production in 2022.
