Imagine a giant jackhammer that runs on a battery instead of messy hydraulic oil. It uses a special type of electric motor that acts like a powerful piston to break rock. This means no more oil leaks, way less noise, and a much cleaner way to demolish or mine.
Hydraulic breaker hammers are inefficient, cause environmental pollution through oil spills, and have high operating costs. They lack the precision and digital connectivity required for modern zero-emission mining and construction sites.
A fully electrical impact hammer (LEH) based on a tubularic linear permanent magnet motor. This includes three pilot units, a user manual, and a digital control system.
If you are a mining site operator dealing with high fuel costs and oil spills — this project developed an electric hammer that reduces CO2 emissions up to 100% and saves energy up to 80%. It eliminates hydraulic oil consumption and lowers total cost of ownership by 35 to 50%.
If you are a fleet manager dealing with expensive maintenance of hydraulic breakers — this project developed a digitalized electric hammer that saves up to 80,000 EUR per hammer over 4 years. It provides higher precision and allows for adjustable striking sequences.
If you are an OEM dealing with the pressure to electrify your product line — this project developed a tubularic linear permanent magnet motor technology. This allows you to integrate a zero-emission hammering solution that is CE marked and tested on 13-ton excavators.
Based on available project data, the electric hammer offers a 35 to 50% lower total cost of ownership, with specific savings of up to 70k€ to 80k€ per hammer over 4 years.
The project has successfully assembled three hammers for pilots in Finland and Germany with OEMs in the construction and mining industries, indicating a transition toward industrial scale.
Lekatech has a strong IP portfolio including 10 granted patents and 1 granted utility model, with 7 new patents filed during the RHINO project specifically for core hammer technology and control.
Yes, the project reports that Lekatech obtained the CE marking for the hammer, which includes the necessary technical documentation.
The system was tested by attaching it to a standard hydraulic 13-ton excavator, suggesting compatibility with existing heavy machinery frames.
The project is led by a single Finnish SME, LEKATECH OY, which acted as the sole partner. This 100% industry-led structure allowed for rapid development, resulting in 41 deliverables and 7 new patent applications within 24 months, focusing heavily on commercialization and OEM integration rather than academic research.
