KOMATSU PC160LC-7 TIER 3 CRAWLER EXCAVATOR

Technical Description

The Komatsu PC160LC-7 Tier 3 is a compact hydraulic excavator engineered for versatile construction applications including trenching, site preparation, and material handling. Powered by a turbocharged Komatsu SAA4D107E-1 diesel engine with 272 cubic inch displacement, the machine delivers 115.4 net horsepower at 2,200 rpm, meeting EPA Tier 3 and EU Stage IIIA emissions standards while reducing NOx emissions by 30 percent. The excavator features an operating weight of 37,787 pounds with four selectable working modes—Power, Economy, Breaker, and Lifting—allowing operators to optimize engine speed, pump flow, and system pressure for specific job requirements. The hydraulic system incorporates a maximum pump flow of 312 liters per minute with adjustable relief valve settings across implement, travel, swing, and pilot circuits. With dual boom and stick configurations, the machine achieves maximum digging depths ranging from 19.6 to 20.6 feet and ground reach extending to 30.3 feet. The bucket capacity ranges from 0.5 to 1.3 cubic yards, accommodating diverse excavation needs. The compact design, measuring 6.9 feet in height to cab top with an 8-foot tail swing radius, enables maneuverability in confined urban environments. The undercarriage utilizes PC210-class components with seven track rollers and two carrier rollers per side, providing enhanced lateral stability and drawbar pull of 156 kilonewtons. Standard features include a hydrostatic two-speed travel system with automatic shift, maximum travel speed of 3.5 mph, slip-resistant steps, and ergonomic cab controls for extended operational comfort.
