Hitachi EX Series Wiring Harnesses – Built to Withstand Harsh Australian Conditions

Did you know that we manufacture direct replacement harnesses for Hitachi EX series machines, including the EX3600-5, EX3600-6, EX5500-6 and EX5600-6? These “fit and forget” harnesses are built to handle the extreme heat, vibration, and environmental wear that often lead to early failures in OEM systems.

Designed and manufactured right here in Australia, our harnesses use high-performance braiding and robust construction methods to deliver reliable, long-term performance—reducing electrical issues and unplanned downtime.

We’ve helped operators across mining and heavy industry extend machine life and boost productivity with wiring harnesses that are made to last. Whether you need a single replacement or are looking for fleet-wide support, we offer:

• One-off custom harness manufacturing

• Small volume production for maintenance teams

• Large volume and bulk orders for ongoing operations
