When you need even extra flexibility in confined spaces, such as digging alongside buildings or walls, our PC138US-8 excavator with offset boom 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 NZ-wide service and support network.
