TRT Builds an All-Steering Mini Quad for Robinson Heavy Haulage
OVERVIEW
Robinson Heavy Haulage worked with TRT on a new all-steering mini quad deck widener for heavy haulage work around Coffs Harbour.
The trailer gives Chris Robinson a compact, steerable and low-tare solution for tight streets, low-profile equipment and daily project work.
SITUATION
Chris Robinson owns and operates Robinson Heavy Haulage and Robinson Earthmoving.
His haulage business began around 15 years ago after he bought a truck and float to support the needs of his earthmoving operation.
Today, Robinson Heavy Haulage runs 12 trucks and 10 trailers, including five floats.
The business works mainly in civil construction and mining, with trucks now operating as far as Weipa, Darwin, Perth and Broome.
Chris bought his first TRT quad axle widener in 2013.
The new all-steering mini quad is his fifth heavy haulage trailer from TRT.
CHALLENGE
Robinson Heavy Haulage needed a trailer to support daily work on the Coffs Harbour Bypass Project.
The project includes tight streets, difficult access and regular heavy haulage close to the business’s home base.
The trailer needed to carry indivisible loads and single heavy items while staying practical on a wide range of roads.
It also needed a low loading angle for low-profile machines and a tare weight that supported heavier oversize loads.

SOLUTION
TRT manufactured a new all-steering mini quad deck widener for Robinson Heavy Haulage.
The 19-metre trailer widens to 3.5 metres and can carry single items up to 35 tonne.
The trailer has a top deck and a lower deck.
It also avoids the gooseneck layout used on many low loaders, which helps keep the design compact and practical for Chris’s work.
All-wheel steering gives the trailer strong manoeuvrability through corners, roundabouts and tight streets.
That was important for the Coffs Harbour Bypass work, where access can be limited.
TRT also focused on tare weight and loading angle.
The trailer sits at about 14.5 tonne, with 3.3 metre ramps and a 10 degree loading angle for low-profile machinery.
MADE POSSIBLE:
Robinson Heavy Haulage now has a trailer matched to its daily bypass project requirements.
It gives the team better access through tight local streets while supporting heavy, indivisible and oversize loads.
Chris has pointed to all-wheel steering as a major advantage for manoeuvrability and tyre wear.
He expects all-wheel steer quad floats to support tyre life of 90,000 to 100,000km.
The project also reflects a long working relationship between Robinson Heavy Haulage and TRT.
What started with one TRT trailer in 2013 has grown into five heavy haulage trailer purchases, with a further customised 5x8 low loader planned.
