On-Site Repairs for Heavy Diesel Equipment
At TBR Mechanical, we provide heavy machinery repairs in Darwin and throughout the NT, bringing diesel mechanical support directly to the equipment. Our work covers heavy commercial trucks and prime movers. We also repair diesel-powered excavators, dozers and loaders used in mining, civil construction and earthmoving. We do not repair cars, utes or 4WDs, and our service does not involve workshop drop-offs.
Mechanical problems may emerge during routine operation or be found when equipment is serviced. We assess the reported fault and carry out repairs or maintenance suited to the machine and the work required. For organisations operating several commercial diesel vehicles, our heavy vehicle fleet maintenance work helps address servicing across the fleet. Call 0437 815 155 and tell us what has stopped working and where the equipment is located.

Heavy Trucks & Machinery We Service
Heavy machines have different duties, but each needs repairs that account for how it is used and the environment in which it operates.
- Prime movers & heavy trucks: We assess reported diesel faults in prime movers and heavy commercial trucks at their operating location.
- Excavators & loaders: We work on heavy diesel machines used for excavation, loading and material movement. Service requirements vary with operating hours and the work the machine performs.
- Dozers & civil plant: Our repair scope includes diesel machinery supporting civil and construction projects. A mechanical issue can affect other site activities when one machine is unavailable.
- Mining & industrial equipment: We assist operators with heavy diesel machinery at industrial sites and mines. Access arrangements and the equipment's operating role are important details when organising a visit.
