Komatsu PC238USLC-11 Hydraulic Excavator

Komatsu PC238USLC-11 Hydraulic Excavator Information

The PC238USLC-11 is Komatsu’s latest tight tail swing excavator, utilizing a Komatsu SAA6D107E-3 engine to meet Tier 4 Final emissions regulations. A new vicious fan clutch reduces engine parasitic loads, resulting in up to 4% better productivity, when compared to the PC228USLC-10. The PC238USLC-11 maintains the tight tail swing radius of its predecessor, making it well suited for utility and roadway applications working in confined spaces. The PC238USLC-11’s contoured cab profile and sliding door allows the cab to swing within the same radius as the counterweight. Additional counterweight remains standard, giving the PC238USLC-11 equivalent or better lift capacity than conventional models in the same size class.
