Excavator Introduction:
Engineered to excel in the toughest construction, landscaping, and utility operations, the CT230-8A (KPM) redefines mid-size excavation efficiency. This 22.1-ton class champion delivers industry-leading 139kN bucket digging force – effortlessly fracturing rock and penetrating dense soil – while its 110kN arm power ensures sustained performance in trenching and lifting applications.
At this excavator‘s core lies the proven Cummins 6BTA.A5.9 turbocharged engine, generating 133kW (178HP) with a massive 708N·m torque plateau at low RPM. Paired with a dual-pump hydraulic system delivering 460L/min total flow, this machine executes complex movements with lightning response and hydraulic precision.
