Electric and hybrid technologies are being developed in the non-road mobile machinery (NRMM) sector to improve efficiency of operations and to reduce emissions. NRMM are used in many different domains and applications. Thus, the business cases and technical solutions for electrification can be very different depending on the application area. In addition to their benefits, electric systems introduce also new types of safety and dependability related uncertainties and risks that need to be controlled. In this paper, we present findings of semi-structured interviews and a literature study focusing on electrification in the non-road mobile machinery sector. As a result, we provide an overview of the different electrification strategies and a structuring of safety and dependability implications of these strategies.
