PC138USLC-10 Powered by Tier 4 Interim Engine Technology.
EPA Tier 4 Interim and EU Stage 3B Emissions Certified Engine
Built upon Komatsu’s proven EPA Tier 3 technology, the SAA4D95LE-6 maintains engine performance while lowering fuel consumption up to 7%, compared to the previous series. Komatsu’s Tier 4 Interim engine platform uses an advanced electronic control system to manage airflow rate, fuel injection, combustion parameters, and after treatment functions to optimize performance, reduce emissions, and provide advanced diagnostic capability.
Like the previous Dash-8 series, the PC138USLC-10 uses a contoured cab design that is unique because it allows the cab to swing within the same radius as the counterweight. The work equipment is also designed to minimize the front swing radius for better operation in confined areas. With the standard additional counterweight, the PC138USLC-10 provides the same level of lift capacity and stability as a conventional excavator, but with the versatility of a tight tail excavator. An optional dozer blade makes backfilling quick and easy and optional rubber (Roadliner) or steel track shoes are available to match the machine specification to the application requirements.
All of the new 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.
The new cab is loaded with features and provides a comfortable and quiet work environment so operators can maximize productivity. The contoured ROPS certified cab with sliding door is specifically designed for the PC138ULSC-10. The cab is mounted on viscous damper mounts to reduce vibration. An auxiliary input has been added to connect an MP3 player or other device that uses a standard auxiliary plug, along with two 12-volt ports that have also been incorporated into the cab.
The PC138USLC-10 provides easy access to service locations to reduce costly downtime. The new model has a convenient access handrail on the upper structure. The radiator and hydraulic oil cooler are mounted side by side, making maintenance and service simpler. Daily service checks are also easier with wide access service doors.
Komatsu remains focused on lowering the customer’s ownership costs by engineering machines with increased fuel efficiency and productivity. The PC138USLC-10 comes standard with the Komatsu CARE® complimentary factory maintenance program which covers all factory-scheduled maintenance for three years or 2,000 hours, whichever occurs first. Services are performed by factory certified technicians using only Komatsu genuine parts and fluids. Komatsu CARE covers all new Komatsu Tier 4 Interim equipment, whether rented, leased or purchased.
KOMTRAX® Fleet Monitoring
For owners, fleet managers and operators looking to maximize their equipment, the PC138USLC-10 is equipped with the latest KOMTRAX® technology, which sends machine operating information to a secure website utilizing wireless technology. Data such as operating hours, machine location, maintenance notifications, out of area notifications, machine utilization and residual fuel levels are relayed to the web application for analysis. The KOMTRAX fleet monitoring system monitors machine availability, reduces the risk of machine theft, allows for remote diagnosis by the distributor, and provides a wealth of other information to maximize business efficiency.
