Komatsu America Corp. introduces the PC138USLC-11 hydraulic excavator, which has the same tight tail swing radius as its predecessor, and consumes up to 4 percent less fuel. It is ideal for utility and highway applications working in confined spaces.
This new EPA Tier 4 Final-certified model uses an SAA4D95LE-7 engine with a Komatsu Diesel Oxidation Catalyst (KDOC) and a Selective Catalyst Reduction (SCR) system with Diesel Exhaust Fluid (DEF) injection. The engine requires no diesel particulate filter or regeneration system.
“The PC138USLC-11 is the perfect machine for contractors on highway, bridge and other roadwork jobs,” said Kurt Moncini, senior product manager, Komatsu America. “It’s easy to transport, versatile and the tight tail swing fits easily within one lane of traffic.”
The PC138USLC-11’s contoured cab profile and sliding door allow the cab to swing within the same radius as the counterweight. A larger counterweight mass remains standard, giving the PC138USLC-11 equal or better lift capacity than conventional models in the same size class.
Standard features of the new PC138USLC-11 include:
• Tier 4 final Certified Engine Technology:
• Powerful, efficient, SAA4D95LE-7, 4.4 L, 97.2 net HP engine

• Exhaust Gas Recirculation (EGR) to reduce NOx emissions
• Selective Catalyst Reduction (SCR) system, with Diesel Exhaust Fluid (DEF) injection used to meet EPA Tier 4 Final NOx requirements
• SCR catalyst has no scheduled maintenance and a life expectancy similar to that of the engine
