Tristar Industries

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?"

“But Tristar… that’s not a trailer.”
Yeah, we know.
But it is a machine that needed some custom fabrication work to securely mount its fire suppression system — and that’s the sort of job our Darwin workshop is set up to handle.
Our team designed and fabricated a purpose-built mounting bracket to suit the machine and existing fire suppression equipment.
Trailers might be what we’re best known for, but our capabilities go well beyond them — custom steel fabrication, modifications, repairs and one-off solutions for heavy equipment and machinery.
If it needs to be made, modified or made to fit, have a chat with Tristar.

Rollout Friday.

This 32KL Tristar water tanker is heading out with KAS Freight behind one seriously good-looking Kenworth.

Built in Darwin and fitted with a hydraulic self-priming pump, Magnum batter sprays, pressure discharge, gravity drop bars, hose reel, 6" belly discharge and standard road train connections.... to name a few details.

Built for civil, mining, roadworks and remote Australian conditions.

And with that custom airbrush work up front, we reckon this combination will turn a few heads.

Sometimes you just have to stop and admire the SHINY. ✨

Another freshly painted component coming out of the Tristar paint shed and looking the goods.

Good preparation, a quality finish and attention to detail — because even the parts that work hard can look good doing it.

Just a couple of Tristar products doing what they do best — working hard in the Territory.

Designed and manufactured in Darwin, our heavy-duty trailers and transport equipment are built for demanding Australian conditions, from remote civil and mining operations to everyday heavy haulage.

Thanks to G&S Transport, Sage SAGE Landscape Material Supplies, Aldebaran Contracting, Ostojic Group for showing our products in their natural environments.

We might be a little biased, but we reckon this one looks the goods.

Custom-built in Darwin for our long-time customers at Exact Contracting, this Tristar flat top semi-trailer combines heavy-duty construction with a finish that deserves a second look.

Built to last. Built to work. Finished in Exact Contracting’s colours with some great contrast — and because even a hard-working trailer deserves a little truck makeup, the hand-painted scrollwork adds the finishing touch.

But this is only the beginning. This flat top is the first part of a triple road train set that will soon be heading out to work in some of Australia’s toughest conditions.

Sometimes you need to look beyond the shine and dazzle to see what really matters.

Polished alloy might catch the eye, but when you're choosing equipment built to earn its keep, it's what sits behind the shine that counts — quality components, solid engineering, proven reliability and a trailer built for Australian conditions.

Because looking good is one thing. Being built to work is another.

She's a Gen X trailer.

She doesn't need a touchscreen, Bluetooth or lane assist. She was built when steel was thick, engineering was overbuilt and if something broke, you fixed it properly.

This Brentwood 2×8 Low Loader Dolly is currently undergoing a complete low loader dolly refurbishment in the Tristar workshop. The project includes structural repairs, component replacement and a range of carefully considered upgrades to ensure compatibility with modern low loaders while preserving the character of the original design.

For decades, this heavy-haulage dolly has worked on Australian roads and job sites. Now it's getting the restoration it deserves so it can continue working for decades to come.

Follow along as the team at Tristar Industries brings this piece of Australian heavy transport history back to life.

Specialising in trailer refurbishments, heavy haulage repairs, low loader modifications and custom transport equipment.

Built to work. Restored to work longer. Built Tristar Tough.

These are our favourite kind of photos.

Not the polished marketing shots. Not the trailers sitting in the yard waiting for delivery.

These are photos of Tristar equipment earning a living in the real world.

Many thanks to Bede and the team at Aldebaran Contracting for sharing these images from some very remote parts of Northern Australia. From road train side tippers and low loaders to water tankers keeping the dust down, these trailers are working exactly where they were designed to work.

Out here, reliability matters. When the nearest town is hours away and the weather can change in an instant, our customers need equipment they can trust.

That's why every trailer leaving our Darwin workshop is built with one goal in mind:

Get the job done. Then get you home again.

This 32,000-litre portable water tank built for Remote Concrete NT has certainly been attracting plenty of attention—and it's not hard to see why.

We'd like to thank the team at Remote Concrete NT for their continued support and the opportunity to deliver another custom-built Tristar product.

Designed for flexibility, this tank can be secured to a flat-top trailer using container twist locks during transport, then quickly converted to a standalone bulk water storage unit on site using the integrated forklift pockets and support legs (legs for empty use only). One asset, multiple applications, and no wasted equipment sitting around between jobs.

Built for the harsh conditions of Northern Australia, this 32kL unit is proof that practical solutions don't have to be complicated.

We think the sunrise photo looks pretty good, but we're starting to wonder whether the next one should be taken somewhere out in the Tanami. Maybe with a highly customised version parked in front of a certain Kenworth. After all, we've been assured that it can tow it easier than a particular Mack would...
