Komatsu PC138US-11 Hydraulic Excavator

The PC138US-11 hydraulic excavator shows Komatsu’s leadership in technology and innovation with an environmentally friendly EU Stage V Komatsu engine, up to 5% improved fuel efficiency, an upgraded cab design and enhanced safety and serviceability. Productivity is maximised and operating costs are reduced.

The 13 tonne excavator has a rounded profile with minimal protrusions at both the front and the rear. Its ultra-short tail swing radius is perfect for work in tight spaces, particularly in urban areas, or for road construction, logging and demolition. Thanks to optimised packaging, the PC138US-11 is exceptionally stable. Coupled with the machine’s wide working range, this stability makes it ideal for any work requiring long reach, such as demolition jobs and slope cutting. With ample dumping reach available for loading operations, the operator can always work easily, efficiently and with absolute confidence.
