Harness Master Wiring Systems

We provide EV manufacturers and operators with custom cable assemblies, wiring harnesses, and overmoulded solutions to OEM specifications.

Backed by rigorous in-house testing and deep manufacturing expertise, every assembly is engineered to meet the real-world demands of vehicle architecture.

As EV platforms advance, we are committed to ensuring the electrical systems keep pace. HMWS engineers to specification, build in-house, and test to the standard the application demands.

At HMWS, we believe the best solutions are built through collaboration.

We work closely with our clients to understand their challenges and develop tailored manufacturing solutions that meet their exact requirements.

This includes custom wiring harnesses and specialised applications, developed by our experienced team using engineering expertise and manufacturing capabilities to deliver the right solution for your needs.

When a Rotary Blasthole Drill goes down, every minute of downtime counts.

HMWS was engaged to redesign the electrical harness architecture from the ground up, replacing complex OEM systems with a fully integrated, plug-and-play solution designed for reliability, faster fault detection, and easier maintenance in the field.

The result? Reduced downtime, simplified repairs, and a system built for the realities of remote mining operations.

Reworking the Harness Design for a RBH Drill Fleet HMWS redesigns the electrical harness for Rotary Blasthole Drills, boosting reliability, serviceability, and fast repairs in remote mining environments.

Today is the final day at Queensland Mining & Engineering Exhibition (QME) in Mackay.

So far, this event has provided valuable insights into the future of mining, with discussions centred around innovation, automation, safety, and evolving engineering capabilities.

Thank you to everyone who has visited us at stand OP508 so far, and to those we’ll have the opportunity to meet today.

We’ve enjoyed being part of such an important industry event.

At HMWS, we combine automated co axial striping with in house testing and certification across both co axial and Ethernet assemblies.

Every cable we process and manufacture is built for continuity, performance, signal integrity, and is thoroughly inspected to ensure potential issues are identified early rather than discovered in the field.

This capability is further enhanced with overmoulded protection designed to withstand vibration, contamination, and mechanical stress, helping extend service life in heavy industrial applications.

The HMWS Isolator Lockout Range improves safety and reliability in harsh environments.

These mechanical switches isolate power to help prevent accidental or unauthorised start up during maintenance.

Available in multiple of colours for site-specific safety and identification requirements, the HMWS Isolator Lockout Range is a smart investment in both safety and reliability.

At HMWS, investing in technical capability means investing in our people.

Ongoing training and development help ensure our partner facing teams have the skills and knowledge to deliver reliable service. While our apprenticeship program creates opportunities for local talent and supporting the next generation of industry professionals allowing them to deliver quality and innovative HMWS products.

By investing in people today, we are helping build a stronger workforce for tomorrow.

A small addition to our office, but one that says a lot about who we are.

Our new world clocks represent the regions where HMWS operates, reminding us every day of the global partnerships and clients we're proud to support.

Working across time zones keeps us connected, strengthens collaboration, and reflects the people and relationships that make HMWS a truly global business.

Heat, vibration, moisture and chemicals wear a system down over time, gradually, until something gives at exactly the wrong moment.

And when it does, it's rarely the wire itself that's the problem. It's everything around it: the insulation that's been abrading under load, the conductors that have been shifting under vibration, the points where contamination has been finding its way in over hundreds of operating hours.

This is the problem HMWS's overbraiding process is built to solve. By locking conductors in place and reducing internal movement, we cut down the wear that leads to premature failure in high-vibration applications. Combined with high-grade PVC-coated nylon yarns, our harnesses are designed to handle what mining, heavy transport and industrial environments throw at them every single day, including oil, dirt, moisture, heat and everything in between.

The result is a harness that's more resistant to contamination, more flexible and easier to install, and built to last longer between service intervals. In industries where a machine sitting idle costs real money, that's not a small thing.

Built for the environments where reliability isn't optional.

HMWS is partnered with Outback Kitters, a manufacturer and distributor specialising in American truck accessories including bull bars, roof racks, wiring harnesses, and suspension systems.

Through close collaboration and a strong focus on quality, HMWS helped deliver reliable manufacturing support that aligned with the high standards expected by the Outback Kitters team and their customers.

Partnerships like this reflect the value HMWS places on accountability, trust, and long term collaboration.
