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?"

Not exactly built to blend in! 💛🤍

This Tristar water tanker is looking sharp in yellow and white, ready for its quality control checks at our Pinelands workshop in Darwin.

The paint might catch your eye, but the checks matter just as much. Next up, our team will check the finished setup before it’s cleared for handover.

Water tankers built in the Territory, for Territory work.

Who wore it better? 🐶 vs 🚛

Same trailer and dolly. Two very different outfits.

The old-school cool of the Mack Super-Liner, or the Kenworth with its matching blue and white?

We’ve supplied the workshop backdrop here at Tristar Industries in Pinelands, Darwin—you can supply the verdict. 😉

Team Mack or Team Kenworth? Let us know below. 👇

A birthday, Tristar style! 🔧🚛

This truck dolly was modified to suit the owner’s needs, with an adjusted turntable height and the addition of a fuel tank. We then finished the job with abrasive blasting, fresh paint and a rewire and a little pin striping—ready to get back to work and look good at it.

At Tristar Industries in Pinelands, Darwin, we carry out truck trailer and dolly repairs, modifications and refurbishments to suit Northern Territory operators.

The reveal is here—a new lease on life, to customer specs, the Tristar way.

This tipper trailer has undergone an extensive refurbishment at Tristar Industries in Darwin, with work covering the bin, chassis, suspension, hydraulics, electrical and air systems.

The trailer was stripped down and the bin removed for abrasive blasting and painting, with hydraulic issues addressed along the way.

With the chassis exposed, our team:
• Replaced worn suspension components
• Replaced worn chassis components
• Replaced hydraulic lines and hoses, electrical components, and air hoses and fittings as required.
• Added a side toolbox and water tank.
• Replaced the mudguards and mudflaps.

The chassis was also abrasive blasted, painted and finished with fresh decals to complete the transformation.

She may not be the belle of the ball, but she’ll turn a head or two.

A new lease on life, the Tristar way.

This tipper’s seen a few hard yards, but its story isn’t finished yet. Here’s a sneak peek at its rebirth—with its identity intact and a fresh chapter taking shape.

We’re keeping the full picture under wraps for now. Stay tuned for the finished result.

It’s the moist season in the Top End, and water tankers have been the flavour of the month at Tristar Industries.

Built in Darwin for Northern Territory conditions, every water tank setup is tested before handover, so it arrives ready to get to work.

Need replacement machinery parts—but the manufacturer is on the other side of the planet?

Long lead times and international freight can turn one worn component into a costly stretch of downtime.

Before you order from overseas, ask Tristar Industries in Darwin about a local solution.

Our machining and fabrication team can assess whether we can manufacture a replacement component or repair your existing part, right here in the Northern Territory.

Send us a photo, drawing or sample, along with the machine details and what you need the part to do.

Can Tristar help? Ask us. You might be surprised.

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.
