Field Service Mechanics& Breakdown Support
Trade-certified field service mechanics deployed directly to your mine site. Onsite mining equipment maintenance, rapid breakdown response, and hydraulic diagnostics across Western Australia and Queensland. We keep your fleet operational — wherever you operate.
Onsite. Ready. Deployed to Your Site.
JHD Maintenance provides experienced field service mechanics who work directly at your mine site — eliminating the cost and delay of transporting equipment to a workshop. Whether you need a mobile diesel fitter for a scheduled service, an onsite diesel mechanic for a breakdown, or a full field service crew for a planned shutdown, we deploy qualified personnel to where the work is.
Our mechanics work across all major heavy equipment platforms — excavators, loaders, dozers, haul trucks, drill rigs, and support machinery. We carry the diagnostic tooling and parts inventory to handle most faults in the field, keeping your downtime to an absolute minimum.
We operate across active open-cut and underground mining operations in Western Australia and Queensland, including remote and fly-in fly-out sites. Our team understands the operational pressures of mine-site environments and works to your schedule — not ours.
When Downtime Matters
Every hour your equipment is down on an active mine site has a direct cost. JHD Maintenance is structured to respond — whether you need emergency support right now, or you're planning ahead for scheduled servicing and want a reliable mining maintenance contractor on call.
We work with mine operators, civil contractors, and heavy equipment operators across WA and Queensland. Short-term breakdown response, long-term maintenance contracts, roster-based field service support — we structure our engagement around what your operation actually needs.
