Komatsu Launches New Addition to Dash-10 Excavator Series

Thu February 14, 2013 - National Edition
Construction Equipment Guide

With an operating weight range of 31,791 to 32,628 lbs. (14,420 to 14,800 kg), Komatsu’s PC138USLC-10’s short tail swing radius makes it an ideal machine for confined work areas such as one lane of traffic or urban environments. The EPA Tier IV Interim and EU Stage 3B emissions certified machine is the newest addition to Komatsu’s Dash-10 excavator line up.

Designed with the customer in mind, the PC138USLC-10 has a net horsepower of 93.5 hp (68.8 kW), powered by a Komatsu SAA4D95LE-6 engine. Built upon its Tier III engine platform, Komatsu has leveraged its leadership in technology and innovation to design a more environmentally-friendly engine that maintains the proven performance of the previous series while reducing daily costs and fuel consumption according to the manufacturer.

The PC138USLC-10 features improved hydraulic efficiency, improved operator comfort, and simplified maintenance, yet retains the versatility and performance of the previous model. The standard additional counterweight provides the same level of lift capacity and stability that a conventional tail swing excavator provides, but uses a contoured cab design that allows the cab to swing within the same swing radius as the counterweight.

Special features of the new PC138USLC-10 include:

• EPA Tier IV Interim and EU Stage 3B Emissions Certified Engine

Built upon Komatsu EPA Tier III technology, the SAA4D95LE-6 maintains engine performance while lowering fuel consumption up to 7 percent, compared to the previous series. Komatsu’s Tier IV 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.

The new Komatsu Diesel Catalyst (KDOC) has an integrated design allowing this simple system to remove soot using 100 percent “passive regeneration” without the need for a diesel particulate filter (DPF). Unlike a DPF, the KDOC does not have a scheduled replacement interval and is designed for long life with no maintenance required. Less complexity and truly seamless operation for the operator means lower owning and operating costs.

A new variable flow turbocharger, direct flow air filter, high-pressure common rail fuel injection, 16-valve cylinder head and exhaust gas recirculation (EGR) also are part of the design of the PC138USLC-10. The result is precise air flow management and more complete combustion, eliminating the need for a DPF.

• Versatile Performance

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 also is 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.

• Highly Efficient Hydraulic System

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.

• Enhanced Operator Environment

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 also have been incorporated into the cab.

A new high resolution 7 inch LCD color monitor features enhanced capabilities and 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 rearview monitoring system allows the operator to view directly behind the machine with the push of a button.

• Convenient Maintenance and Serviceability

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 also are easier with wide access service doors.

The machine is equipped with the Komatsu EMMS (equipment management monitoring system) with diagnostic features that give the operator and technicians greater monitoring and troubleshooting capabilities. EMMS also continuously monitors all critical excavator systems, tracks the preventative maintenance schedule and provides troubleshooting assistance in order to minimize diagnosis and repair time.

• Komatsu Care

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 IV 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 Web site 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.
