When you need high productivity and plenty of digging power in confined spaces, our PC138USLC-11 excavator – now powered by a Komatsu low emission Tier 4-Compliant engine – is the perfect choice. As with all our construction excavators, key components are designed and manufactured by Komatsu to work together in an integrated package. And it comes standard with our Komtrax remote monitoring and location system, backed by our Australia-wide service and support network.

Features and benefits
Short implement swing radius
Get greater clearance when space is limited with a higher boom raise angle than our standard excavator that reduces the minimum front implement swing radius.
Short tail swing radius
Get more done in confined areas with the short tail swing radius that allows the machine to work in more spaces than our conventional excavator.
Rounded cab design with sliding door
High maneuverability is achieved through the purpose-built cabs that swings within the same radius as the counterweight. The sliding cab door allows operators to easily enter and exit when space is limited.
Stable platform
The compact counterweights provide exceptional lifting capability and stability providing a comfortable, confident operating experience.
Arm quick return valve
Help improve efficiency with the quick return valve that directs additional oil through a second line directly back to the tank when the arm is extended, helping to reduce back pressure and fuel consumption.
Efficient hydraulic system
For quick response to operator demands, the closed-center loading system (CLSS) helps improve fuel efficiency. Pilot proportional control (PPC) hydraulics and optional proportional joysticks provide exceptional control.

Tier 4 Engine KDPF Regeneration
As the technology of diesel engines has progressed from Tier 3 to Tier 4 Final, design aspects of the engines have been fine-tuned to comply with regulations to cover regulated diesel engine exhaust pollutants.
The result is that these new diesel engines are cleaner than ever before, and in many cases more fuel efficient too. Along with this comes the need to properly manage and maintain these new generation of machines to make sure that operating costs are minimised.
