One of the most important machines underground… doesn’t move a single tonne of ore. Our #Elphinstone UG20M grader. On paper it doesn’t look like a production machine. But in reality it directly impacts the productivity of every truck in the mine. Good haul roads mean: • faster truck cycle times • less fuel burn • longer tire life • less operator fatigue Good haul roads make a big difference in truck productivity, fuel consumption, and tire life. All thanks to a machine that never appears in the production report. Our UG20M is based on a Caterpillar 140M platform, modified by Elphinstone for underground work. A few interesting specs: • ~173 hp CAT engine • ~23–25 tonnes operating weight • 3.7 m (12 ft) blade • full articulation for tight mine drifts • heavy guarding and low-profile design for underground clearance A bit of history: Elphinstone started in Tasmania in the 1970s modifying Caterpillar equipment for underground mining. Their graders became the industry benchmark. Caterpillar eventually acquired the underground mining portfolio in 2018, but many of those machines are still built on the original Elphinstone designs. What’s the most underrated machine on your mine site?
