Clients often come to us wondering, “What is a full trailer and how does it differ from a semi trailer?”. Full trailers are used in a wide range of applications across Australia, including mining, agricultural, and construction industries.
In this guide, we’ll cover “what is a full trailer”, the differences between a full trailer and semi trailer, and when to use a full trailer. As leading experts in Australia’s heavy haulage industry, we’re here to help you make an informed decision on the right type of trailer for your needs.
What Is a Full Trailer?
A full trailer features both front and rear axles. Full trailers also feature a drawbar and coupling that get connected to the towing vehicle.
With independent axles, full trailers carry their own weight using the wheels and do not transfer additional weight to the towing vehicle. This ensures even weight distribution and minimises the load placed on the towing vehicle.
Common Uses in Australia
Full trailers are used in a wide variety of applications. In Australia, full trailers are often used to transport cargo over short distances. With their higher stability compared to semi-trailers, full trailers are ideal for situations when the towing vehicle is unable to bear additional weight.
Here are some of the common uses of full trailers in Australia:
- Mining
- Agriculture
- Construction
- Heavy machinery transport
- Forestry
- Short-distance, local cargo transport
Key Differences Between Full Trailers vs. Semi-Trailers
Connection Mode
- Full trailers: Full trailers use a drawbar and coupling mechanism. This connection mode offers flexibility and stability but does require precise alignment.
- Semi trailers: Semi trailers use fifth wheel coupling, offering good maneuverability and efficiency.
Design
- Full trailer: Full trailers have both front and rear axles and a drawbar.
- Semi trailers: Semi trailers do not have a front axle. The towing vehicle takes on a large portion of the towing weight.
Axles
- Full trailers: With independent axles and a drawbar, full trailers offer excellent flexibility, stability, and even load distribution.
- Semi trailers: Semi trailers have axles at the front of the trailer.
Applications
- Full trailers: With a high level of stability, full trailers are optimal for rough terrain.
- Semi trailers: Their versatility makes semi-trailers ideal for long-haul transportation.
| Full Trailer | Semi Trailer | |
| Connection Mode | Drawbar and coupling mechanism | Fifth-wheel coupling |
| Design | Independent axles and a drawbar; designed to haul heavy loads without making the towing vehicle handle additional weight | No axles at the front of the trailer; the towing vehicle takes on some of the hauling weight |
| Axles | At the front and rear end | All at the rear end |
| Applications | Rough, uneven, or off-road terrain; local haulage needs | Heavy haulage over long distances |
Pros and Cons of Full Trailers and Semi Trailers
Pros of Full Trailers
- Capable of carrying large volumes of cargo
- Ideal for transporting bulky materials or oversized loads
- Can be customized to accommodate a diverse range of cargo types
- Can have tie-down points, shelving, ramps, and additional features added
- High level of stability and even weight distribution

- Versatile and highly customisable
- Various trailer types available to fit the cargo needs
Cons of Semi Trailers

- Higher fuel consumption
When to Use a Full Trailer vs. Semi Trailer
Choosing between a full trailer and semi trailer will depend on your transportation needs, the terrain, and transport distance.
With their high stability and even weight distribution, full trailers are often used for transporting heavy machinery or oversized loads over rough terrain. With both front and rear axles, full trailers offer higher flexibility and stability than semi-trailers. This makes them ideal for local deliveries and shorter transports.
We recommend a full trailer as your best option when:
- Stability is a top priority
- You are hauling heavy loads over rough or uneven terrain or off-road conditions
- Your towing vehicle cannot handle additional weight
- You need short distance transport to terminals, ports, factories, and warehouses
- Only a portion of the cargo is unloaded at each destination
We recommend considering a semi-trailer if:
- An entire load needs to be delivered to one destination
- Maneuverability and efficiency are priorities for the load transfer
- You need to haul heavier or larger loads
- You are involved in logistics or long-haul transportation
- You need a high level of versatility for varying cargo types
