Mobile heavy diesel mechanic · Blackwater QLD
Broken down?We come to you.
Heavy diesel repairs, servicing, diagnostics and auto electrical for mining, quarry, civil and farm plant. Field service from Blackwater across the Central Highlands and the Bowen Basin.
01 · The real cost
A machine that isn't running isn't earning.
Every hour a dozer, a truck or a crusher sits idle costs more than the repair. Our whole job is getting you back to work, and keeping you there.
Maximising mean time between failure
Breakdown
The machine stops when it wants to, usually on the worst day. Every fix is an emergency and every emergency costs double.
Repaired properly
Root cause found, not just the symptom. The same fault does not bring the machine back next month.
Serviced on schedule
Hours-based servicing, inspection reports and a defect list. Downtime becomes something you plan, on a day you choose.
This is where we come in
Find the fault. Not just the symptom.
Fault codes, live data, wiring, pressures, temperatures. Trade-qualified in automotive electrical technology with diesel engine-management diagnostics, so the intermittent fault that only shows up under load gets found too.
Four faults found. All four fixed on site.
02 · How a call-out works
Three steps. Back to work.
The same drill whether it is a starter motor on a ute or a crusher drive on a quarry floor.



You call. We triage on the phone.
What is the machine, what is it doing, where is it, and how urgent. Two minutes on the phone usually tells us what to bring, so the first visit is the fix, not a look.

We come to the machine.
Mine site, quarry, roadside or paddock. The ute carries diagnostic gear, tools, common parts and consumables. Inductions and paperwork are sorted before we roll through the gate.

Fixed, tested, written up.
The fault gets fixed at the cause, the machine gets run up and load-tested, and you get a job sheet with photos and a note on what to watch. Then it goes back to earning.

07 · Who turns up
The bloke on the phone is the bloke with the spanner.
No service desk. No apprentice sent on his own. You talk to Sid, Sid turns up.
S & P Robinson Heavy Diesel is owned and operated by Sid Robinson, a Blackwater local with a trade background in auto electrical and heavy diesel work and years on mine sites and around heavy plant. He has been fixing the machines that keep Central Queensland moving since 2023.
Mechanical and electrical in one person means no waiting for the "other bloke" to come out. Whether the fault is a snapped belt or a sensor that only plays up at operating temperature, it gets found and fixed on the same visit.
