Mack Trucks Trident

The Mack Trident is a familiar sight on Australian highways and with good reason: it’s a versatile truck that can handle just about anything.

One of our biggest-selling models, the Mack Trident is hugely popular in the demanding long-haul and heavy construction sectors.

Haul up to 131 tonnes

If you’re pulling B-Doubles across Australia, running a tipper and dog at a construction site, or hauling logs out of the mountains of New Zealand, the Trident gets the job done with ease.

Axle Back or Axle Forward?

When we say versatile, we mean it. That’s why we offer Trident with two steering axle positions, designed for specific applications: Axle Back and Axle Forward. This is how we can build Tridents as logging trucks, low-loaders, interstate B-Doubles, tipper & dog and more. 

Trident Axle Back

If you’re involved in operations such as long-haul or logging, you know that correct weight over the steer axles is critical. This is where the Trident Axle Back hits its stride.

B-Double (Axle-Back) 
The front axle is 1,297mm from the front, providing the turning circle and weight distribution you need.

Trident Axle Forward

Running a tipper & dog? Trident Axle Forward is the model for you.

The front axle is 737mm from the front, perfect for extreme axle measurements to maximise the payload of tipper and dog configurations.
