KOMATSU PC228USLC-2 CRAWLER EXCAVATOR

Technical Description

The Komatsu PC228USLC-2 is a compact hydraulic excavator engineered for confined space operations and urban construction applications. Powered by a turbocharged Komatsu S6D102E-1 engine, it delivers 132.8 horsepower at 2000 rpm with a displacement of 358.9 cubic inches, featuring a 66.1-gallon fuel capacity for extended operational periods. The machine weighs approximately 49,659 pounds in operating configuration, maintaining a relatively compact footprint with an overall width of 10.2 feet and a short tail swing radius of 5.6 feet, making it ideal for restricted work areas. With dual boom and stick options, the excavator provides maximum cutting heights ranging from 33.5 to 35 feet and digging depths between 21.2 to 22.4 feet, accommodating various excavation tasks. The maximum reach along ground extends to 31.8 feet with the longer boom option. Equipped with a 1.6 cubic yard bucket capacity, the machine balances productivity with maneuverability in tight quarters. The hydraulic system operates through a main pump delivering 109 gallons per minute at peak capacity, with maximum system pressure of 290 kilograms per force per square centimeter. Ground pressure of 6.9 psi minimizes surface disturbance on sensitive job sites, while the undercarriage features 49 shoes per side with 23.7-inch dimensions and nine track rollers per side for stability and traction. Maximum drawbar pull reaches 45,195 pounds, and travel speed capabilities extend to 3.3 miles per hour, enabling efficient repositioning on site. The swing mechanism operates at 11 rpm with standard monitoring systems and remote engine oil filter mounting, facilitating straightforward maintenance in field conditions.
