How to spec a fuel or service trailer
A fuel trailer earns its keep by removing the daily run to the bowser. Sized correctly, one unit replaces a forklift, a pallet of jerry cans and three crew trips per day, paying itself off inside a season on most construction and mining sites. Sized wrong, it's an expensive paperweight that needs a 6x4 tow vehicle just to move empty.
1. Match tank size to daily fuel burn
Start with the litres your plant consumes in a typical week, then size the trailer to cover four working days. That leaves a one-day buffer for delivery delays without forcing crews to walk off a face. Most mid-size civil sites land at a 1,000 to 2,200 L tank. Larger mine and quarry fleets often run two 4,400 L trailers in rotation so refuelling never blocks the working zone.
2. Decide single vs multi-compartment
Single-compartment builds are simpler to maintain, lighter empty and cheaper up front. Multi-compartment builds split the same volume across two or three isolated chambers, each with its own pump and meter. That's the practical answer when a mixed fleet runs diesel plant, petrol generators and AdBlue trucks off the one trailer. Each chamber gets its own dipstick and fill point so cross-contamination isn't possible.
3. Choose the right pump and nozzle package
Pump flow rate sets your refuelling speed. 60 L/min diesel pumps suit utes, light trucks and small plant. 80 L/min pumps shave minutes off filling earthmoving plant. Petrol pumps run a tighter spec (anti-static reels, vapour-recovery nozzles where required) so don't share a petrol pump with a diesel circuit. Filtered nozzles and inline water separators are cheap insurance against injector failures.
4. Compliance, plates and paperwork
Above-ground bulk fuel storage in Australia is governed by AS1940 (fire and spill containment), AS1692 (tank construction) and the Australian Dangerous Goods Code 7.9 (transport). Self-bunded construction satisfies the bund requirement without a separate concrete pad. Each trailer ships with chassis-mounted ID plates, placarding ready for transport, and a declaration of compliance. That's the package most councils, principal contractors and mining operators expect during site induction.
5. Plan delivery, registration and service
Standard builds dispatch from our Brisbane warehouse in 5 to 10 business days. Custom multi-compartment builds run 4 to 8 weeks. Registration is straightforward in QLD, NSW, VIC and SA. We supply the build plate, weight ticket and ATM declaration the transport department needs. First-year service is included on every build, and we run authorised in-house repairs nationally for the pump packages we supply.
