When you need big-machine productivity and plenty of excavating power in confined spaces or busy urban areas, our PC228US-11 excavator – now powered by a Komatsu new technology engine – is an ideal solution. The PC228US-11 is also available with blade. 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 tail swing radius
The PC228US/LC-11 is an ideal machine for applications such as road work, underground utilities or other applications where a conventional excavator will not fit. The contoured cab design and convex sliding door allow the cab to swing within the same radius as the counterweight. Trucks can be positioned closer to the machine when working within one lane of traffic, improving operator confidence and job efficiency.
Fuel consumption reduced
The PC228US/LC-11's new tier 4 final engine along with enhancements in the hydraulic system considerably decreases fuel consumption. Fuel consumption reduced by 4% compared to the older model.
Low vibration with viscous cab mounts
The PC228US/LC-11 uses viscous mounts for the cab that incorporate a longer stroke and the addition of a spring. The cab damper mounting combined with a high rigidity deck reduces vibration at the operator’s seat.

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.
