Komatsu America Corp's newest EPA Tier 4 Interim Excavator, is the PC170LC-10.Improved performance, lift capacity and greater fuel efficiency are a few of the benefits of Komatsu America Corp’s PC170LC-10 excavator, the newest addition to its dash-10 series.

With operating weights ranging from 38,100-41,600 lbs., the PC170LC-10 provides improved performance with up to 5 percent more lift capacity with the standard counterweight, while an optional heavier counterweight provides up to 15 percent more lift capacity when compared to the previous model the PC160LC-8.

The heavier counterweight option is ideal for contractors looking for a more powerful excavator. The lighter counterweight machine offers mobility and can be hauled on a 40,000 lb. tag-along trailer, embodying versatility with power for applications such as residential and non-residential construction.

The cab of the PC170LC-10 has a high-resolution 7-in. LCD color monitor that displays information in 25 languages for global support. The operator can easily select from six working modes of operation to match machine performance to the application.  

These working modes include Power Mode, Economy Mode, Heavy Lift Mode, Breaker Mode, Attachment Economy and Attachment Power. The new monitor panel also provides Eco Guidance (operational efficiency guidance), operational records, fuel consumption history, and utilization information. The standard rear-view monitoring system allows the operator to view directly behind the machine with the push of a button.

The PC170LC-10 offers a net 115HP at 2100 rpm, yet it is up to 10 percent more fuel-efficient than its predecessor, depending on the application and conditions. This improved efficiency comes in part from a variable-flow turbocharger that provides optimal airflow under all speeds and load conditions.

All of the excavator’s major components including the engine, hydraulic pump, motors and valves are exclusively designed and manufactured by Komatsu. This integrated design employs a closed center load sensing hydraulic system that takes hydraulic efficiency to the next level, utilizing both variable speed matching and low speed matching technology.  

Variable speed matching allows the engine speed to adjust based on the hydraulic pump output for both light and heavy-duty applications, while low speed matching utilizes a larger pump capable of producing higher pump output at lower engine speeds. Enhanced working modes are designed to match engine speed, pump delivery, and system pressure to the application.

The PC170LC-10 does not have a scheduled replacement interval for its Komatsu Diesel Oxidation Catalyst (KDOC). The KDOC integrated design allows the system to remove soot using 100 percent “true passive regeneration” without the need for a Diesel Particulate Filter (DPF). The KDOC is designed for long life without a scheduled replacement interval. Less complexity and truly seamless operation for the operator means lower owning and operating costs.

To reduce owning and operating costs further, all PC170LC-10 excavators are covered by Komatsu CARE, Komatsu’s complimentary scheduled maintenance program for three years or 2,000 hours (whichever occurs first). Factory-certified technicians use only Komatsu genuine parts and fluids to perform these services.

The excavator is powered by either an EPA Tier 4 Interim or EU Stage 3B Emission Certified Engine depending on market.

Built on Komatsu’s proven Tier 3 technology, the SAA4D107E-2 engine provides lower emissions and lowers fuel consumption.  The Komatsu Tier 4 Interim engine uses an advanced electronic control system to better manage air-flow rate, fuel injection, combustion and exhaust after-treatment to optimize performance, reduce emissions, reduce fuel consumption and provide advanced diagnostic capability.

The excavator is equipped with the exclusive Komatsu Equipment Management Monitoring System (EMMS), which provides enhanced diagnostic features that give the operator and technicians greater monitoring and troubleshooting capabilities. The system continuously monitors many critical systems, as well as the planned maintenance schedule, and provides troubleshooting assistance to minimize diagnosis and repair time.  

KOMTRAX technology, which is fully integrated with Komatsu’s Tier 4 technology and sends machine operating information to a secure website utilizing wireless technology. Hour meter, location, cautions, load ratio, fuel consumption and maintenance alerts – to name a few of its features – are relayed to the web application for analysis.

The KOMTRAX fleet monitoring system increases machine availability, reduces the risk of machine theft (compared to machines not KOMTRAX-equipped), allows for remote diagnosis by the distributor, and provides a wealth of other information to drive business efficiency and productivity.
