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.
