When you need high productivity and plenty of digging power in confined spaces, our PC138US-11 excavator is the perfect choice. 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.
- No DEF required, eliminating AdBlue® handling, storage and refilling.
- Proven Komatsu performance, offering powerful hydraulics with dependable productivity.
- Tight tail swing design, ideal for confined and urban worksites.
- Fuel-efficient operation for optimised working modes and advanced hydraulic control.
Resources
Features and benefits
Short tail swing radius
Short tail swing radius of the PC138US-11 allows the machine to work in more confined areas than a conventional machine.
Fuel consumption reduced
Fuel consumption is reduced up to 9% using a temperature controlled viscous fan clutch and improved engine and hydraulic system efficiencies.
