Komatsu Excavator Features Greater Lift Capacity


Komatsu America Corp.’s PC170LC-10 excavator is the newest addition to its dash-10 series. With operating weights ranging from 38,100-41,600 lb., the PC170LC-10 provides improved performance with up to 5 percent greater lift capacity with the standard counterweight, while an optional heavier counterweight provides up to 15 percent greater lift capacity when compared to the previous model PC160LC-8.

Komatsu Excavator PC170LC-10The heavier counterweight option is ideal for contractors looking for a more powerful lifting machine. The lighter counterweight machine offers excellent 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 PC170LC-10 offers a net 115 hp at 2,100 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.

Power and Control
All of the new excavator’s major components including the engine, hydraulic pump, motors and valves are 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.

Seamless Operation = Greater Productivity
The PC170LC-10 does not have a scheduled replacement interval for its Komatsu Diesel Oxidation Catalyst (KDOC). The KDOC integrated design allows this simple 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.

Lower Owner 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.

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.

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

Latest Fleet Monitoring System
The PC170LC-10 is equipped with the latest 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.
