As part of a collaborative project between Umeå Institute of Design and Atlas Copco, I led the design of the ER-40 Electrorun Safety Wrench. The objective was to address the challenges faced by operators during high-torque bolting tasks, particularly in confined and hazardous environments. By conducting extensive field research and engaging with end-users, we identified key pain points, including cumbersome equipment setups, safety risks, and lack of feedback during operations.

The ER-40 was conceived to consolidate multiple tools into one, reducing the need for separate nut runners, wrenches, and safety nuts. Its design features include dual handles for improved ergonomics, safety flaps to prevent accidental drops, and an integrated feedback system that communicates operational status through visual cues. This holistic approach not only simplifies the bolting process but also significantly enhances safety and efficiency on-site.
