Etteplan on board Epiroc’s Minetruck MT42 battery-trolley project

Finland-based engineering firm, Etteplan says it is collaborating with Epiroc to enable fossil free underground heavy transportation without interruptions and, more specifically, helping redesign its Minetruck MT42 Battery into an electric trolley system.

As part of a strategic partnership project that started in 2021, Etteplan’s offices in Finland and Sweden are providing what it says are crucial resources and expertise in the development, helping secure a timely progress of the project. It is providing technical expertise for battery technology, machine electrification, electrical design, system requirements and safety risk assessment.

Last year, Epiroc, for its part, announced a collaboration with ABB and Boliden to develop an all electric battery trolley truck system based on the MT42 Battery truck for underground mining, with the trio planning to demonstrate the system on a test track in the underground polymetallic Kristineberg mine in Sweden.

For Epiroc, the trolley truck project is one of the initiatives to meet its ambitious sustainability targets and forms part of its electrification journey, Etteplan said. The new battery-electric Minetruck MT42 trolley will still be equipped with a battery and, in addition, it will be recharged on the fly via an overhead catenary wire through a pantograph, similar to a trolley bus.

Anders Svensson, Director, Service Solutions at Etteplan’s Engineering Solutions, said: “Globally, electrification of equipment is a major trend in mining, where most vehicles are currently powered by diesel engines. Therefore, the industry needs new types of competences and skill sets that we are ready to cater for. Jointly developed procedures together with major manufacturers such as Epiroc ensure that we address strategically important electrification challenges in a competitive way.”

Etteplan has worked with Epiroc, previously part of Atlas Copco, for over 20 years, and the project aligns with Etteplan’s electrification vision while showcasing how it works closely with customers to enhance their battery performance and functionality in different industries.
