Road Train Trucks For Sale In Australia

About Prime Movers

Prime movers power the transport and hauling industries in Australia. From simple single-trailer loads on up to quad-trailer road trains and other configurations, prime movers allow haulage firms to attach the right trailer for the job and deliver equipment or goods where they need to go.

Prime Mover Axle Configurations

6x4 prime movers are typically more common in Australia, though 4x2, 8x4, 6x6, and 10x4 are just some of the other axle configurations you might find in service on the road. Heavy-duty jobs, such as towing oversized loads or working on forestry or mining jobsites, are more likely to call for a truck with an 8x4 or 10x6 configuration, while 6x2 or 6x4 trucks are commonly used for freight transport. You might also see trucks with a lazy axle (a non-driven axle in the rear axle group), a lift axle (a non-driven axle that can be raised with lighter loads), or a pusher axle (a lift or lazy axle in the front of an axle group). 

The best axle configuration for your truck depends on your planned gross combination weight (GCW), axle load, road conditions, and topography.

Day Cabs & Sleeper Trucks

Day cab trucks are often selected for delivery, distribution, and other short-range hauling jobs. These trucks have no sleeping area as they are primarily used for hauling freight and equipment during regular daytime shifts. 

Sleeper trucks feature an extra compartment to the rear of the driver’s cab that is outfitted with a bunk, a refrigerator, storage space, and other amenities where the driver can relax and sleep through the night on long hauls scheduled to last more than a day. A sleeper truck gives drivers the flexibility to park the truck when their workday is over and eat and sleep in it, rather than mapping out roadside food and lodging along their route.

Cabover vs. Bonneted Prime Movers

Prime movers are available in cabover designs, where the cab is mounted over the engine, or as conventional trucks with a bonnet covering the engine and a cab mounted behind it. Cabover trucks offer a space-saving design, ideal for haulers who operate in areas with strict length laws, and some drivers prefer this configuration as they don’t need to see around the bonnet. Conventional trucks, on the other hand, can generally accommodate more powerful engines and pull larger loads, and some drivers favour the comfort of a cab behind the engine rather than above it.
