From 8t utility excavators to 80t mining-class machines — Japanese-engineered hydraulic systems delivering superior digging force, fuel efficiency, and cycle times across 85 countries.
Each Sumitomo excavator integrates precision hydraulic controls, fuel-optimized engine management, and reinforced structural integrity.
Sumitomo excavators are designed around our proprietary LEGEST hydraulic system — delivering precise load-sensing control that matches hydraulic flow to operator demand in real time. The result: up to 15% lower fuel consumption per operating hour compared to conventional open-center systems, without sacrificing digging force or cycle speed.
"We evaluated five excavator brands for our copper mine expansion. Sumitomo's SH350 delivered the highest breakout force-to-weight ratio and the lowest fuel consumption per BCM moved. After 8,000 hours, the undercarriage wear is tracking within manufacturer specifications — which is unusual for our abrasive ground conditions."
