When it comes to customised engineering solutions for the mining and heavy equipment industries, few companies match the depth, expertise, and hands-on ingenuity of HAMR Engineering. From line boring and CNC machining services to the supply and manufacture of advanced mechanical parts, we don’t just fix what’s broken — we build smarter, tougher, longer-lasting components designed for the challenging environments of Western Australia.
Based right here in Kalgoorlie-Boulder, we know what it means to work hard and get the job done right. Whether you're working underground, on site, or in a regional workshop, our fit-for-purpose fabrication, precision machining, and innovative upgrades keep your equipment reliable, safe, and efficient.
At the heart of our innovation is the HAMR Conversion—our flagship upgrade for Sandvik LH514, LH517, and LH621 boggers. Developed through years of practical fieldwork and customer collaboration, the HAMR Conversion pin and collet system delivers longer life, better wear resistance, and reduced downtime.
If you're not already using the HAMR Conversion bucket kits—you might be missing out. Our kits are being shipped across WA and internationally to places like Queensland and even Alaska, where our LH621 variant recently achieved a standout 7800-hour life cycle.
From tilt link mounts to bogger bucket pins, HAMR Engineering manufactures and machines a wide range of high-strength brackets and reinforcement components. Our work includes:
If your equipment frame is wearing out before the component does, you need a HAMR upgrade.
We’ve become a go-to name in conversion kits for Sandvik boggers, especially the LH517 and LH621 variants. Our in-house designs include:
Each of these are designed to improve component service life and reduce frame wear, saving you money on downtime and long-term repairs.
We don’t just design these parts — we 3D print prototypes, test-fit them, and trial them in the field before rollout. That’s the HAMR difference.
Need replacement components for your MT65 Epiroc fleet? HAMR Engineering stocks and supplies a full list of high-wear pins and bushes, including:
All are manufactured to tight tolerances to ensure OEM fitment and reliable performance.
We’re constantly adding to our product range based on what our customers ask for. Some of our latest custom-engineered solutions include:
All backed by our expert support, ready for dispatch across Australia and beyond.
We’re not just fabricators — we’re line boring and machining specialists. Our in-house and mobile line boring teams help reduce downtime and improve your turnaround.
Our fabrication team delivers it all. If you need a custom part or build that can handle real-world abuse, we’ve got the skills and equipment to make it happen.
HAMR Engineering offers onsite line boring throughout the Goldfields and beyond.
Downtime is costly, especially when remote mining operations rely on quick turnarounds. Our mobile line boring service is designed to reduce wait times and keep your machines moving.
From loader pivots to excavator bores, we can restore your gear to spec fast. With certified line boring technicians and rapid-response schedulling, you get:
Every good upgrade starts with smart engineering.
That’s why we use CNC machining, 3D modelling, and even 3D printing to test and verify each component before it ever reaches your site.
Our CNC machines are set up to handle both small- and large-scale production runs. From one-off custom pins to full batch component production, our CNC machining ensures precision and repeatability with tight tolerances.
We also support:
Whether you need a once-off emergency part or a long-term partner for custom equipment, we’ve got the capability to deliver.
Our customers come to us because we solve problems. Whether it’s delivering four full LH517-BD-RK kits, a new LH517-TL-RJ kit, or building a new centre hitch for a TH663i, we manufacture and ship quickly across the Goldfields and Australia-wide.
Trial installations of our HAMR CONVERSION components have shown incredible results:
This is why entire fleets, from the Goldfields to Queensland, are switching over to our upgrade kits.
We’re proud to be a WA company supporting WA industries—but our reach is global. Whether it’s a dozer blade, a dog bone, or a complete pre-delivery conversion, we’re shipping high-performance parts to clients across the world.
At HAMR Engineering, we don’t just build metal – we build confidence.
We’re not in the business of quick fixes. We’re here to engineer smarter, longer-lasting solutions for the real challenges faced by miners, mechanics, and maintenance teams across Western Australia.
Whether you’re in the Goldfields, out in the Pilbara, or managing a mine site overseas, HAMR Engineering is ready to help you cut costs, reduce downtime, and improve safety with better parts and service.
So if you’re ready to get more out of your fleet, it’s time to GET HAMR’D.
