For high productivity and plenty of digging power in confined space – along with a dozer blade for enhanced productivity – our 15.1 tonne PC138US-8 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.
