Equipment Overview
The Hitachi EX1900 is a 192-tonne excavator built for ultra-large-sized production in mining operations, available in backhoe or front-shovel configuration and designed to pair well with the Hitachi EH1700 haul truck. The rigid box design and integrated cast steel structural components give the machine strength built to last, while an Engine-Pump Control system efficiently adjusts power to match load demand. A Hitachi-patented auto-levelling mechanism, combined with large bucket capacities, contributes to efficient, high-volume production.
Power comes from a Cummins QSKTA38-CE engine producing 810 kW (1,086 hp) at 1,800 rpm. Bucket capacity ranges from 4.4 to 12.0 m³ in backhoe configuration, with bucket digging force reaching 671 kN and arm crowd force 620 kN. The advanced hydraulic system tops the industry for smooth, efficient combined operation of the front attachment and swing, delivering quick cycle times, and easy-to-check sight gauges and fluid access simplify servicing and inspection.
