Tristar Industries Leading Australian manufacturer of side tipping semi-trailers, water and fuel tankers, low loaders, dollies and custom-engineered transport equipment.

Proudly manufacturing in Darwin, Northern Territory. Tristar Industries is a pioneering and innovative Darwin manufacturer of door opening side tipping semi-trailers, water and fuel tanks, low loaders, dollies and other mining, transport and heavy earth–moving related equipment. We have the capacity to build a wide range of equipment tailored for our customers. Tristar Industries has a successful 30 year history of manufacturing side tippers, water tanks and other heavy earth mining equipment to companies all over Australia, proving that when you have a superior product the distance and remoteness are not an issue for clients. Tristar was one of the first companies in Australia to build Side Tipping Semi Trailers and continues as a leader in their design and development. Tristar also has a substantial involvement in the design and construction of mining and other engineered equipment. Tristar has on site their own mechanical engineer, profile cutter, press operator, diesel mechanics, auto electricians, machinists, hydraulic experts and some of the best welders/boilermakers in the country. Tristar products are made from high quality, heavy duty components to give them a long and useful life, minimized risk of breakdown and downtime and ease of maintenance. Low hydraulic pressure reduces potential damage to hydraulic hoses and hoists. A low centre of gravity aids the stability for both on and off–road application and can handle a wide range of products. They can be built single, double, triple or special road train configurations with left or right hand side opening doors. Much of the equipment Tristar builds is used in the harsh environment of the top end of Australia on mine sites where the road conditions can be very taxing on all types of mining equipment. Regular haul road usage on mine sites will quickly uncover any weakness in the materials used to fabricate equipment. You have no choice but to use the best materials when designing and building trailers that will routinely be subjected to those conditions. Boasting one of the biggest manufacturing sites in the NT consisting of 2 fabrication sheds, trailer fit out shed, sand blast and paint shed, machine shed and full functioning spare parts store. Requiring 70 staff members made up of welders/boilermakers ,auto electricians, diesel mechanics, fitters and turners, sand blasters, industrial spray painters, trailer fitters, draftsman, mechanical engineer, press operator, tyre fitter, store man, trades assistants, apprentices and our administration staff to keep up with the demand in work. Currently producing over 120 side tipping semi trailers and 30 water tanks per year as well as fuel tanks, belly dumpers, low loaders, drop deck trailers and other specific clients requests we are left asking "what economic downturn?"

Who said a hub cap had to look ordinary?

A customer wanted something that would do the job and look right on their truck. So our machine shop made this custom oil hub cap from billet aluminium, complete with an oil level sight glass.

The original is on the left. The Tristar version is on the right.

Functionality? Check. Coolness? Also reading high on the sight glass. 😎

The little trailer that makes a big combination possible.

Fresh out of the Tristar workshop: a red tri-axle converter dolly, ready to earn its place on the road.

It might tag along behind a rigid body for a dog trailer, or blend into a road train combination between trailers. Either way, this is a serious piece of heavy transport gear, built here in Darwin.

One Tristar tipper looks good. Four looks even better.

A quad road train loaded up with Tristar bowl tippers, built for the sort of heavy-duty work and long distances that come with operating in the Northern Territory and remote Australia.

Designed and manufactured in Darwin, our bowl tippers are built for demanding mining, civil construction, bulk haulage and road train operations where strength, reliability and payload matter.

And when you put four of them behind a Mack like this, they certainly make an impressive combination.

Bent, twisted and definitely having a bad day.
This excavator arrived with a badly bent hydraulic cylinder rod and a twisted dog bone linkage—but our team had the capability to bring it back.
The hydraulic cylinder was repaired and the damaged linkage was rebuilt and reinforced by the Tristar team, ready to return to work.
From hydraulic cylinder repairs and machining to heavy fabrication and equipment repairs, Tristar Industries has the in-house capability to tackle the jobs that don’t come with an easy replacement part.

Built to work. Repaired to work again.

Old-school Mack fans, this one’s for you. 🐶💚

Long bonnet, a bit of chrome and plenty of attitude—this sexy old girl knows how to turn heads.

This classic v8 Mack Superliner is visiting Tristar Industries in Darwin for a few jobs under the bonnet and around the back end. A little workshop attention to keep the old girl doing what she does best.

We love seeing a truck with this much character in the shed.

Who’s got a Superliner story? Let’s hear it in the comments. 👇

1980s vintage—and still earning its keep. 💪

This veteran Ostojic tipper trailer is in our Darwin workshop for a service. With a replacement bin fitted along the way, it’s a great example of how maintenance, repairs and refurbishment can extend the working life of equipment.

At Tristar Industries, we help keep hardworking trailers working, with trailer servicing, repairs and refurbishment right here in Darwin.

This is what we like to see — Tristar trailers out there doing trailer things.

NorthStar Pastoral sent us these shots of their Tristar drop decks loaded up and working as a triple road train — with a pretty bloody impressive Kenworth leading the charge.

Containers are just one of the jobs these drop decks are built to handle, and paired with a truck like that, the whole combination certainly looks the part.

A big thanks to NorthStar Pastoral for continuing to put their trust in Tristar, and for sending us photos of our gear where it belongs — out on the road, working.

Isn’t it cute? It’s like a water tanker… only smaller. 😄

This 20KL Tristar water tank is compact enough to fit neatly onto the front deck of an A-trailer, providing a practical water storage and transport option without needing a dedicated tanker and mounts direct to your existing 20 foot twist locks.

Another Tristar-built tank heading out with Remote Concrete — designed around the job it needs to do.

From 20KL tanks like this one through to full-size 32KL water tankers, we build water storage and transport solutions that can be customized to suit the application.

We hooked Lamm Civil up!
Yes, it’s a Dad joke. It’s Father’s Day. We’re qualified.
Lamm Civil brought us this hook lift truck with nothing on the back, so the Tristar team got to work.
The result: a custom-built hook lift bin and flat top with removable loading ramps, giving them two practical options from the one truck — all finished in matching silver and looking the goods.
Another example of what we can design and manufacture right here in Darwin when an off-the-shelf solution just doesn’t quite cut it.
Thanks to Lamm Civil for trusting Tristar with the build.

Three more Tristar water storage and transport solutions rolling out!

A big thank you to Remote Concrete for choosing Tristar Industries to deliver these three units.

Built here in Darwin for the demands of remote, civil and construction operations, these units provide a practical solution for bulk water storage and transport wherever the job takes them.

We genuinely appreciate the support of local businesses like Remote Concrete and the opportunity to keep building equipment that goes to work across the Territory.
