Technical Description

The Komatsu PC170LC-10 is a mid-size utility crawler excavator engineered for versatile jobsite applications requiring compact dimensions with substantial digging power. Powered by a Komatsu SAA4D107E-2A turbocharged diesel engine, the machine delivers 115 net horsepower at 2,100 rpm while maintaining compliance with EPA Tier 4 interim and EU Stage IIIB emissions standards. The excavator features an operating weight range of 38,100 to 41,600 pounds with multiple boom and stick configurations providing maximum digging depths from 18.5 to 20.6 feet and maximum reaches extending to 30.3 feet. The bucket digging force reaches 24,471 pounds across all boom options, supported by arm crowd forces ranging from 17,417 to 20,503 pounds depending on configuration. The machine incorporates six operating modes—P, E, L, B, ATT/P, and ATT/E—that optimize engine speed and hydraulic flow for specific working conditions, reducing fuel consumption up to 10 percent compared to previous models. Hydraulic system specifications include a 298-liter-per-minute pump flow capacity with relief valve settings of 380 kg/cm² for implement and travel functions. The undercarriage provides a maximum travel speed of 3.5 mph with 35,163 pounds of drawbar pull, supported by seven track rollers and 44 shoes per side. The spacious operator cab features full air suspension, low-vibration design, and a large high-resolution LCD monitor for enhanced visibility and comfort during extended operations.
