Technical Description

The Komatsu PC380LC-7 is a mid-size hydraulic crawler excavator engineered for demanding construction and earthmoving applications. Powered by a SAA6D114E-2 turbocharged engine with aftercooler, this machine delivers 242 horsepower at 1900 rpm, providing the operational power necessary for heavy digging and material handling tasks. The excavator weighs 87,560 pounds with an operating voltage of 24 volts and maintains a 141.6 gpm hydraulic pump flow capacity, ensuring efficient performance across all hydraulic functions. The PC380LC-7 offers three boom and stick configurations to accommodate varying project requirements. Option 1 achieves a maximum cutting height of 31.9 feet and digging depth of 20.4 feet. Option 2 extends capabilities to 33.2 feet cutting height and 21.6 feet digging depth, while Option 3 maximizes reach with 34 feet cutting height and 23.8 feet digging depth. All configurations feature maximum reach along ground between 32.7 to 35.9 feet, enabling versatile positioning for complex excavation tasks. Dimensionally, the machine spans 9.8 feet in width and maintains a tail swing radius of 11.4 feet, with ground clearance of 2.4 feet. The underbody utilizes a robust dual-track system with 49 shoes per side and offers excellent drawbar pull of 74,800 pounds with ground pressure of only 10 psi, minimizing surface damage. Operating at 2.7 mph maximum travel speed, the excavator carries a 159.9-gallon fuel tank and 49.7 gallons of hydraulic fluid, supporting extended operational periods on jobsites. Its swing mechanism rotates at 9.5 rpm for rapid repositioning.
