Engine Specifications The CLG922D
Excavator is powered by a Cummins engine with a gross power of 112 kW and a net power of 102 kW, both at 1,950 rpm. It features a peak torque of 614 N.m at 1,500 rpm, with six cylinders and a displacement of 5.9 L. The engine complies with Tier 2 / Stage II emission regulations.
Performance and Capacity
The excavator has a maximum digging depth of 6,615 mm and a standard bucket capacity of 1 m3. It operates at a weight of 22,000 kg. The bucket breakout force is 145 kN under normal conditions and 159 kN with boost, according to ISO standards.
Hydraulic and Swing Systems
The hydraulic system features a main pump total flow of 420 L/min, with relief pressures of 318 bar (main) and 333 bar (boost). The swing system operates at a speed of 12 rpm.
Undercarriage and Track Drive
The undercarriage includes a shoe width of 600 mm, with 49 shoes per side, 8 bottom rollers, and 2 upper rollers per side. The maximum travel speed is 4.9 km/h, with a gradeability of 70% and a drawbar pull of 195 kN.
Working Ranges
The excavator's reach at ground level is 9,705 mm, with a maximum dig height of 9,540 mm and a dump height of 6,770 mm. The maximum dig depth of a vertical wall is 5,655 mm.
Service Capacities
The fuel tank capacity is 412 L, engine oil capacity is 25 L, cooling system capacity is 30 L, hydraulic reservoir capacity is 230 L, and the total hydraulic system capacity is 330 L.
Load and Lift Capacities
The load capacities are compliant with ISO 10567 standards, ensuring they do not exceed 87% of hydraulic lifting capacity or 75% of the tipping load. The lift point ratings are provided for various heights and reaches, indicating the load is limited by hydraulic capacity rather than tipping capacity.
