The Beginning of the TracStar®: The first TracStar® made its debut in 1997 at the Phelps Dodge mine in Morenci, Ariz., one of the largest copper mines in the world. The self-propelled, self-contained, track-mounted 500mm fusion machine took on the rugged terrain with great success. Today, it is the flagship of our machine line with a full range of machines from 28″ up to 48″ OD. Mobility, ease of use and productivity — that’s what you get with the TracStar!
