Lesjöfors has been a trusted partner for Earthmill in maintaining high-performance wind energy systems

WITH THE share of renewable energy more than doubling from 2004 to 2022, Lesjӧfors’ component supply for the evolving energy sector has followed a similar trajectory.
Working with Earthmill, one of the market leaders in supplying service and maintenance solutions to wind turbine owners, a team in Cornwall, from Redruth-based Lesjӧfors Heavy Springs UK, has developed an industry specific platform that is progressively establishing Lesjӧfors as a spring supply expert within the field.
Wind power spring innovation
"Evolving our spring designs to align with advances and innovations in wind turbine designs is only possible through customer relationships, the like of which we have with Earthmill," said Luke Smith, MD of Lesjӧfors Heavy Springs UK.
"Our technical platform enables us to learn design advances alongside our customers, to listen and share experiences, to understand the unique environmental demands on the product and to deliver spring solutions that meet the rapidly advancing technologies and materials associated with renewables.
"Earthmill’s dedication to providing the very best customer service and supplying only the most efficient and reliable technologies to their customers is a value we mirror at Lesjӧfors. The drive to achieve the highest quality across both our operations has resulted in a wealth of wind energy expertise.”
Sustainability verification value
This year, the Lesjӧfors Group achieved verification from the Science Based Target Initiative (SBTi) - committing to drive ambitious climate action across its global organisation. Achieving this first for the spring manufacturing industry, the group has also heightened it’s focus on working closer with the renewables sector.
"Our working partnership with Earthmill, and other renewable customers, is mutually beneficial and valuable as it is based on the sustainable values that drives us. Designing technical solutions that delivers against these values is one of the most rewarding elements of our work," added Justin Simmonds, technical manager at Lesjӧfors Heavy Springs UK.
Partnership secures performance
"As wind energy continues to be a key supplier of electricity, the demands on the industry and the environment, are increasingly under pressure. Partnerships with quality component suppliers is essential for the network to operate at the turnover required. This is why our customer relationship with Lesjӧfors is so crucial, as we know we can trust and rely on their springs and supply service to meet the demands of our industry," concluded Earthmill’s head of operations, David Smith. "The group’s focus on a more sustainable pathway is also a key reason why they are such a valued supplier."
The Lesjӧfors Group is also working to enhance its product development process, engaging with customers and suppliers to increase the share of recycled metals, developing lower carbon footprint metals across its product line.
