The Komatsu PC400LC-8 hydraulic excavator has a Komatsu SAA6D125E-5 turbocharged, after-cooled, six-cylinder engine producing 345 flywheel horsepower (FWHP). It has an operating weight of 97,148 to 103,834 pounds (44,066 to 47,098 kg). It comes standard with an electronically controlled High Pressure Common Rail (HPCR) fuel injection system, which has Tier III emissions certification.

The PC400LC-8 has a level three Komtrax fleet-monitoring system, which uses wireless technology to send machine operating information to a secure website. The data, including operating hours, location, cautions, and maintenance alerts, is then analyzed. It is also equipped with a Komatsu Equipment Management Monitoring System (EMMS), which monitors all critical excavator systems, tracks the preventative maintenance schedule, and provides error codes and troubleshooting assistance.[1]

This machine has an LCD monitor capable of displaying data in 10 different languages. Through the monitor the user can select from five different operating modes: power mode, economy mode, lifting mode, breaker mode, and attachment mode. The operator can also control air conditioning, machine maintenance tracking, and the image from a rearview camera.[2]

The boom and arms were modified to increase their strength and extend their life by manufacturing them as large cross-sectional structures with thick, high-tensile strength steel, interior partition walls, and large one-piece castings. The PC400LC-8 has two boom mode settings.[3]

Metal guard rings protect all the machine’s hydraulic cylinders and the hydraulic hoses are equipped with O-ring seals to prevent leaking.

The cab is highly pressurized to keep dust from entering the operator’s compartment.

The Komatsu PC400LC-8 has a track gauge of 108 inches (274 cm) with 35.4-in (90-cm) shoes. It is also available with an optional variable track gauge.

The PC400LC-8 has a HydrauMind closed-center hydraulic system with load sensing and pressure compensated valves and a variable displacement piston-type pump with five selectable working modes delivering 182.3 gallons (690 L) per minute at a system pressure of 5,400 lbs per square inch (37,231.7 kPa).
