The fleet

110 trucks, 260 trailers

Specified for petroleum, dangerous goods and liquids cartage.

Combinations

Tri-axle semis to triple road trains

With 19 m and 25 m B-Doubles and 30 m A-Doubles in between.

Maintenance

A maintenance manager, coordinators and full-time mechanics on our payroll.

The combinations ladder

Six combinations, one rule: match the rig to the run

Our fleet combinations include tri-axle semi-trailers, truck and quad-dog, 19 and 25 metre B-Doubles, 30 metre A-Doubles, and AB and Triple Road Trains. Which one turns up depends on your volumes, your site access and the route approvals between our depot and your gate.

Silhouettes are indicative, drawn to one shared scale.

  1. 01

    Tri-axle semi-trailer

    One prime mover, one tanker trailer. The unit for single-site drops and the tight approaches a longer combination can't take.

  2. 02

    Truck and quad-dog

    A rigid tanker towing a four-axle dog trailer: more product than a rigid alone can carry, while staying nimble enough for restricted sites.

  3. 03

    B-Double

    19 m and 25 m

    A prime mover with two trailers coupled in a B formation. The workhorse of Australian fuel distribution; we run both 19 metre and 25 metre configurations.

  4. 04

    A-Double

    30 m

    Two full-length trailers joined by a converter dolly, 30 metres end to end. More product per movement on the corridors approved to carry them.

  5. 05

    AB Road Train

    A B-Double set towing a third trailer on a dolly. Built for the long regional legs where the distance between drops rewards every extra litre on board.

  6. 06

    Triple Road Train

    Three trailers behind one prime mover: the most product a single driver can move, on the routes gazetted to take it. The top of the ladder.

Combinations at work

Proof, seven days a week

The ladder isn't a brochure, it's the working shape of the business. As Prime Mover Magazine reported, we keep Coolangatta Airport's jet fuel supplied with four dedicated A and B-double units, seven days a week, as part of a joint venture operation. Read our summary of that story.

We pioneer new tanker combinations and routes with safety leading every decision. It's how a Maitland fuel agency grew into a network servicing the east coast out to the NT border and Gulf Country: the right combination on the right run, again and again since 1960.

In-house maintenance

A fleet is only as good as its upkeep

Every combination on this page is kept roadworthy by our own people. Our maintenance team consists of a Fleet Maintenance Manager, four coordinators and three full-time mechanics, working alongside the schedulers who plan the runs.

And maintenance isn't tracked on goodwill. Our NHVAS-accredited Safety Management System logs training, maintenance and safety together, so the service history behind any truck arriving at your site is a system record, not a memory.

It shows in recruitment too: a quality fleet maintained in-house is one of the reasons drivers come and stay.

Fleet renewal

Buying Volvos since the Maitland days

By Volvo Trucks Australia's own telling, the Volvo habit goes back to the Maitland years of the 1960s. In 2023 that relationship put the 75,000th Australian-built Volvo into our fleet, handed over by Volvo Group Australia. Today 43 Volvos run under the Hills swoosh. The story, and Andrew's full words on why, are on our news page.

"Volvo's trucks are the safest and most reliable in the market."

Quick answers

What freight buyers ask about the fleet

What's the largest combination you can put on a job?

AB and Triple Road Trains sit at the top of the ladder, with 30 metre A-Doubles and 25 metre B-Doubles below them. What actually runs comes down to the route approvals and your site access; tell us the job and we'll match the rig.

Who maintains the fleet?

Our own team: a Fleet Maintenance Manager, four coordinators and three full-time mechanics, with every service recorded in our NHVAS-accredited Safety Management System.

What safety technology runs on the trucks?

GPS tracking and dashcams monitor routes in real time, backed by our Fatigue and Distraction Management and Cargo Risk Management programs. More on the safety spine is on our about page.

Can you service tight or small-volume sites?

Yes. The ladder runs down as well as up: tri-axle semis and truck and quad-dog combinations exist exactly for the sites a B-Double can't turn into.
