A powerful Komatsu SAA6D107E-3 engine provides a net output of 123 kW 165 HP. This engine is EPA Tier 4 Final emissions certified.
The PC238USLC-11's P mode provides improved performance in demanding applications.
Productivity Compared to the PC228USLC-10 in P modeThe PC238USLC-11 uses a Closed-Center Load Sensing System (CLSS) that improves fuel efficiency and provides quick response to the operator's demands. The control system matches engine and hydraulic demand at the most efficient point under any load condition. There have also been improvements in the main valve and hydraulic circuit to reduce hydraulic loss, resulting in higher efficiency and lower fuel consumption.
When the arm is extended, the quick return valve directs additional oil through a second line directly back to tank which reduces back pressure. Reduces fuel consumption and improves efficiency.
A temperature controlled viscous fan clutch improves engine efficiency and reduces engine power requirements when operating in cooler temperatures.
The PC238USLC-11's compact 6.7 mt 14,815 lb counterweight provides exceptional lifting capacity and minimizes rear swing radius for operation in confined areas.
1810 mm 5'11" short tail swing radius of the PC238USLC-11 allows the machine to work in more confined areas than a conventional machine.
Raising the boom on the PC238USLC-11 to a greater angle enhances overall working performance. Job sites that require a taller upper reach, such as demolition and slope cutting, also benefit from the increased digging and dumping ranges of the PC238USLC-11.
Working range
Max. digging height: 10700 mm 35' 1"
Max. digging depth: 6620 mm 21' 9"
Max. digging reach: 9875 mm 32' 5"
An optional three camera system provides a bird's eye view (including cab visibility) of the machine and surrounding area. This system improves operation and situational awareness on the jobsite
KomVision benefits operators working in urban environments, confined spaces, and high traffic jobsites from increased visibility and situational awareness.
Distance markers are displayed in the monitor to show machine tail swing radius.
