The Komatsu PC228USLC-1 is a compact hydraulic excavator engineered for confined space operations, delivering robust performance in restricted environments. Powered by a Komatsu S6D102E-1 engine producing 128.8 horsepower at 2000 rpm, this machine generates 95 kilowatts of net power with a displacement of 358.9 cubic inches. The excavator operates with a hydraulic system featuring a pump flow capacity of 108.9 gallons per minute and a relief valve pressure setting of 5050 psi, supported by a 63.2-gallon fluid capacity. With an operating weight of 50,485.9 pounds, the PC228USLC-1 maintains excellent maneuverability through its ultra-short tail swing radius of 5.4 feet and low ground pressure of 6 psi, enabling operation on sensitive surfaces. The undercarriage utilizes 27.6-inch shoes with a 7.9-foot track gauge, achieving a maximum travel speed of 3.2 miles per hour. The swing mechanism operates at 11 rpm with efficient hydraulic control. The working envelope encompasses a maximum cutting height of 35.2 feet, maximum reach along ground of 31.8 feet, and maximum digging depth of 22.4 feet. The bucket capacity ranges from 0.9 to 2 cubic yards, with a reference capacity of 1.1 cubic yards, providing versatility for various excavation tasks. Equipped with a 62.1-gallon fuel capacity, this machine delivers extended operational range. The compact shipping dimensions of 29.2 feet length and 9.9 feet height facilitate transport and deployment in urban construction and demolition applications where space constraints are critical.
