KOMATSU PC228USLC-10 CRAWLER EXCAVATOR

Technical Description

The Komatsu PC228USLC-10 is a compact hydraulic excavator engineered for confined space operations with an ultra-short tail swing design. Powered by a Komatsu SAA6D107E-2 turbocharged six-cylinder engine, this machine delivers 158 net horsepower at 2000 rpm with 116 kilowatts of output. The engine meets EPA Tier 4 Interim and EU Stage 3B emissions standards, utilizing a Komatsu Variable Geometry Turbocharger for optimized performance across varying load conditions. Equipped with dual variable displacement piston pumps supplying 475 liters per minute through a closed-center HydrauMind hydraulic system, the PC228USLC-10 achieves impressive working forces with ISO-rated bucket digging capacity of 149 kilonewtons and arm crowd force of 108 kilonewtons. The machine operates at maximum travel speeds of 5.5 kilometers per hour in high range with three-speed automatic transmission and hydrostatic drive. Maximum digging depth reaches 6.62 meters with a 9.7-meter ground-level reach and 10.7-meter maximum cutting height, accommodating bucket capacities from 0.50 to 1.20 cubic meters. At approximately 24,550 kilograms operating weight, the excavator maintains a compact footprint with a 6-foot tail swing radius and 3.18-meter width, optimizing maneuverability in restricted work areas. Advanced features include six operating modes—Power, Economy, Lifting, Breaker, and dual Attachment modes—allowing operators to optimize engine speed, pump flow, and system pressure for specific applications. Standard equipment encompasses 126-liter hydraulic tank capacity, 30-liter cooling system, and integrated monitoring diagnostics for predictive maintenance and troubleshooting capabilities.
