Yanmar develops electric prototype
Yanmar has unveiled a prototype of a cutting-edge electric work machine (3-tonne-class) with advanced force control at the Construction DX Challenge 2023, organised by the Japanese Ministry of Land, Infrastructure, Transport, and Tourism. Developed in collaboration with JAXA's Space Exploration Innovation Hub Center, the large SEA (Series Elastic Actuator) was part of a prototype for the next-generation work machine under the Moonshot Research and Development Program.
Yanmar HD successfully implemented force control capabilities, which is a challenge for conventional hydraulic systems. The SEA comprises an electric motor, reducer and spring, and functionality was implemented in an electric mini-excavator. Rated load during lifting is 209kg, and operating range is 210 degrees. This technology aims to automate fine manual tasks, addressing labour shortages at construction sites. Moving forward, the company plans to conduct further verification to realise the practical applications of next-generation work machines in construction sites and similar environments.
Aligned with the company’s Yanmar Green Challenge 2050, the Yanmar Group says it is continuing its commitment to realising a sustainable society, contributing to customers' decarbonisation efforts through ongoing developments in electrification and other forward-looking technologies.
