EVO-MT® 4000-6 | LNG Conversion for Komatsu PC4000-6 Excavators

Development Update

The EVO-MT® 4000-6 System represents the first ever LNG conversion of a mining excavator. The first of these systems are expected to be delivered to Russian Copper Company's Mikheevskiy mine in early 2021.


The EVO-MT® System enables operators of Komatsu PC4000-6 mining excavators to substantially reduce operational costs and improve sustainability by substituting diesel fuel with lower cost, cleaner burning natural gas. The EVO-MT® System is comprised of patented and proprietary technologies that allow haul trucks and other larger mining equipment to safely operate on gas percentages that represent a substantial portion of their total fuel requirement. The EVO-MT® System has been designed around an LNG on-board storage capacity equivalent to approximately 50% of the normal diesel fuel consumed over a single shift of operation. Diesel Displacement Rate (DDR) will vary according to the specific engine load profiles. Typically DDR's of between 35% and 50% are seen. Equipment converted to LNG + diesel operation exhibit diesel-like performance in such critical areas as power, response and efficiency.
