What Is a Tandem Trailer? Understanding the Basics
So, what is a tandem trailer exactly? Simply put, it's a trailer fitted with two axles positioned close together. This dual-axle setup distributes weight more evenly across the trailer, providing better stability and higher load capacities compared to single-axle alternatives.
Tandem Axle vs Single Axle: Key Differences
The main difference between tandem axle and single axle trailers comes down to weight distribution and stability. A tandem axle configuration spreads the load across four wheels rather than two, which means less stress on individual tyres and better handling when towing heavy loads. Single axle trailers are lighter, easier to manoeuvre in tight spaces, and more affordable. However, they're limited in how much weight they can safely carry.
For heavier loads, axle trailers with tandem configurations are the clear winner. They offer superior braking performance and maintain better contact with the road, especially on uneven terrain.
Why Tag Trailers Are a Popular Choice for Australian Industries
Tag trailers have become a staple across Australian industries for good reason. These trailers, designed to be towed behind a prime mover or truck, offer flexibility that other configurations simply can't match. Tag a long trailer are particularly popular in construction, agriculture, and earthmoving sectors where equipment needs regular transportation between sites.
Their popularity also stems from compliance benefits. In Australia, tag trailers often fall under different registration and licensing requirements compared to semi-trailers, making them accessible for a wider range of operators.
Tandem Axle Trailer Specifications Explained
Understanding tandem axle trailer specifications is essential before making any purchase. These specs determine what your trailer can safely carry and how it performs under load.
Trailer Axle Sizes and What They Mean for Your Load
Trailer axle sizes directly impact your trailer's load capacity. Common sizes range from 40mm to 75mm diameter, with heavier-duty options available for commercial applications. Larger trailer axles sizes mean greater strength and higher weight ratings.
When assessing trailer axles sizes, consider both the individual axle capacity and the combined rating. A trailer might have axles rated at 2,000kg each, giving a combined axle capacity of 4,000kg. However, the trailer's overall rating also depends on chassis strength and other components.
Trailer Axle Dimensions: Getting the Measurements Right
Trailer axle dimensions include more than just diameter. Track width, spring centres, and overall length all play important roles. Getting these measurements right ensures your trailer handles properly and meets your operational needs.
Standard track widths in Australia typically range from 1,500mm to 1,800mm. Wider tracks provide better stability but may affect manoeuvrability in tight spaces. Always check that your chosen trailer axle dimensions suit both your load requirements and the environments where you'll be operating.
Understanding Weight Ratings and Load Capacities
Every trailer comes with specific weight ratings you need to understand. The Aggregate Trailer Mass (ATM) represents the maximum loaded weight, while the Tare weight indicates the empty trailer weight. The difference between these gives you your payload capacity.
Don't forget about your towing vehicle's limits either. Your trailer's GTM (Gross Trailer Mass) must fall within your vehicle's towing capacity for safe, legal operation.
Types of Tag Trailers Available in Australia
The Australian market offers a variety of tag trailers suited to different applications. Understanding your options helps narrow down the perfect choice.
Tag Along Plant Trailers for Construction and Earthmoving
Tag along plant trailers are purpose-built for transporting heavy machinery like excavators, skid steers, and bobcats. These trailers typically feature reinforced decks, heavy-duty ramps, and high load capacities. Most tag along plant trailers come with beaver tail designs that lower the loading angle, making it easier and safer to drive equipment on and off.
For construction businesses, investing in quality tag along plant trailers pays dividends through reduced equipment damage and faster loading times.
Flatbed and General-Purpose Axle Trailers
Flatbed axle trailers offer versatility that specialised trailers can't match. With a flat, open deck, these trailers accommodate various load types – from palletised goods to building materials. They're ideal for businesses that transport different cargo types regularly.
General-purpose trailers often feature removable sides and headboards, adding flexibility for different load configurations.
Enclosed and Specialty Tag a Long Trailers
Some applications require enclosed tag a long trailer for weather protection or security. These trailers shield valuable cargo from the elements and deter theft during transport. Specialty options include trailers designed for specific equipment types, such as car carriers or livestock transport.
How to Match Your Tandem Axle Trailer to Your Needs
Finding the right trailer means honestly assessing what you'll actually be using it for.
Assessing Your Typical Load Requirements
Start by listing what you'll be transporting most frequently. Consider the heaviest single item you'll carry and add a safety margin. It's better to have capacity you don't always use than to constantly operate at maximum limits.
Think about load dimensions too. A 2.5-tonne excavator requires different deck space than two tonnes of building materials.
Considering Your Towing Vehicle Capacity
Your tow vehicle sets hard limits on what trailer you can safely use. Check your vehicle's maximum towing capacity and ensure any trailer you consider falls comfortably within this limit. Don't forget to account for the weight of fuel, tools, and other items you'll be carrying.
Also verify your vehicle has appropriate braking capacity for trailer combinations above 750kg GTM.
Frequency of Use: Occasional vs Daily Operations
How often you'll use your trailer influences the right choice. Daily commercial use demands heavier-duty construction and premium components that handle constant wear. Occasional users might find mid-range options perfectly adequate.
Consider maintenance requirements too. Frequent use means more regular servicing and potentially higher ongoing costs.
Key Features to Look for When Buying Tag Trailers
Beyond basic specifications, certain features make a real difference to usability and safety.
Ramp Styles and Loading Options
Ramps are critical for plant trailers. Options include fixed ramps, folding ramps, and hydraulic ramps. Hydraulic systems offer convenience but add cost and maintenance complexity. Folding ramps provide a good balance between functionality and simplicity.
Look for ramps with appropriate grip surfaces and sufficient width for your equipment.
Braking Systems and Safety Features
All trailers over 750kg GTM require brakes in Australia. Electric brakes are common and reliable, while hydraulic brakes offer stronger stopping power for heavier loads. Ensure your tow vehicle has compatible brake controllers installed.
Additional safety features worth considering include breakaway systems, LED lighting, and reflective markings.
Deck Materials and Durability
Steel decks offer strength and longevity, while timber decks provide grip and are easier to repair. Some trailers feature checker plate steel for the best of both worlds. Consider what your equipment needs – tracked machinery may require timber to prevent deck damage.
Tie-Down Points and Securing Your Cargo
Quality tag trailers include multiple tie-down points positioned for versatile load securing. Look for recessed points that don't interfere with loading and can handle appropriate loads. Australian regulations require proper load restraint, so ensure your trailer has adequate anchor points.
New vs Used Tandem Axle Tag Trailers
Both new and second-hand trailers offer advantages depending on your circumstances.
Pros and Cons of Buying New
New trailers come with warranties, modern features, and no hidden wear. You can often customise specifications to suit your exact requirements. However, new trailers cost more upfront and depreciate significantly in early years.
What to Inspect When Purchasing Second-Hand
When buying used, thoroughly check the chassis for cracks, rust, or previous repairs. Examine axle condition, suspension components, and brake systems. Verify the trailer has proper compliance plates and registration documentation.
Budgeting and Getting Value for Money
Set a realistic budget that accounts for the trailer itself plus registration, insurance, and any modifications needed. Remember that the cheapest option often costs more long-term through repairs and replacements.
Compliance and Registration Requirements in Australia
All trailers used on public roads require registration. Trailers must meet Australian Design Rules and display valid compliance plates. Check state-specific requirements, as these vary across jurisdictions.
Final Checklist Before You Buy
Before committing, confirm the trailer meets your load requirements, fits your tow vehicle's capacity, includes necessary safety features, has proper compliance documentation, and falls within your budget.
Making a Confident Purchase Decision
Choosing the right tandem axle tag trailer doesn't have to be complicated. By understanding the basics of tandem axle trailer specifications, assessing your genuine needs, and knowing what features matter most, you're well-equipped to make a smart decision.
Take your time comparing options. Visit dealers, inspect trailers in person, and don't hesitate to ask questions. A quality trailer is an investment that should serve you reliably for many years.
Whether you opt for tag along plant trailers for heavy machinery or versatile flatbed designs, the right choice comes down to matching the trailer to your specific requirements. Trust your research, stick to your budget, and you'll find a trailer that makes your work easier and more efficient. Good luck with your purchase!
