Performance & Efficiency

The 110 kilowatt Isuzu AH-6HK1X turbocharged engine supports a hydraulic pump flow of 205 liters per minute at a relief pressure of 350 bar. Its 140 kN bucket digging force and 106 kN arm crowding force provide steady breakout performance for trenching and compacted ground, while the 205 kN drawbar pull and 35-degree gradeability support movement across difficult terrain. The 11.5 rpm swing speed helps maintain quick excavation and truck-loading cycles.
