Complete Guide to Tandem Axle Trailer
In this extensive guide, we take a deep dive into the tandem axle trailer, a reliable alternative to the single axle trailer. We will cover the benefits of owning a tandem axle trailer, the advantages and disadvantages and how to make the most of its many uses.
If you’re looking into buying a tandem axle trailer, this guide will surely provide you with all the information to make an informed decision whether it's the right trailer for you.
What is a tandem axle trailer?
A tandem axle trailer, also going by dual axle trailer, double axle trailer, or two axle trailer – is a much larger trailer than a single. Unlike single axle trailers, tandem axle trailers feature two axles with wheels on both ends which means it has a greater load capacity and better stability on the road.Tandem axle trailers are the most commonly preferred type of trailer when it comes to substantial hauls like transporting construction materials, heavy machinery, large boats, and more. This is mainly because they can carry more weight without compromising on stability.
With its four wheel design instead of two, it significantly reduces the sway and bounce when driven on the road which can sometimes occur with single axle trailers.
Key components of a tandem axle trailer
A tandem axle trailer incorporates several key components, each playing a crucial role in ensuring its functionality and safety. Getting familiar with these elements will help you recognise the signs of wear and tear early on which means you can action repairs sooner rather than later and reduce the risk of accidents.Here are the key components to note:
Axle
In a tandem axle trailer there are two axles that support the frame and these are arranged sequentially to distribute the load evenly across its four tires. The axle is central to the trailer’s design as it determines the weight the overall trailer can load, making it important to consider the axle capacity when selecting a trailer for specific hauling needs.The dual axle configuration also allows for better shock absorption during travel to give you and your load a smoother ride, especially when road conditions are less than optimal
Wheels & tires
The wheels and tires are the most important component as they get the most use when it’s on the road. Quality tires, along with the correct load capacity of the trailer, are essential for safe and efficient transport. Always undergo regular inspections of your tires to make sure they remain in good condition. Additionally, proper tire pressure should be maintained so that the trailer can continue working in optimal condition.Frame
The frame serves as the skeleton of the tandem axle trailer. It provides the structural foundation that supports the load. Most tandem axle trailer frames are fabricated from steel or aluminium and designed to be robust.Knowing your tandem axle trailer frame’s composition and structure will help determine the trailer's load-bearing capacity and compatibility with various types of cargo.
Hitch
For a tandem axle trailer, the hitch is connected between the trailer and the towing vehicle. It’s important to use a hitch that is compatible with the towing vehicle’s hitch type and has a rating suitable for the weight of the loaded trailer. Proper hitch selection and installation will mean a safe and secure towing experience and prevent any accidental detachments while transporting.For a tandem axle trailer, each component above plays an important role and has a specific function. Having an understanding of them enables you to have a safer and more efficient use of the trailer. When you maintain each component properly, you can ensure the longevity and reliable performance of your tandem axle trailer.
Advantages of a tandem axle trailer
Tandem axle trailers come with a host of advantages that cater to both casual and professional users. Below are some of the advantages of a tandem axle trailer and how it stands tall amongst other types of trailers.- Higher load capacity – Tandem axle trailers can carry significantly heavier loads compared to single-axle trailers, making them suitable for hauling more substantial and heavier items.
- Better stability – Thanks to the additional axle design, these trailers offer better stability, especially at high speeds, thus reducing the risk of swaying and providing a smoother ride.
- Better traction – With four tires on the ground, these trailers offer better traction on slippery roads, enhancing safety in even the roughest of weather conditions.
- Better braking system – Tandem axle trailers often come with more efficient braking systems, providing better control during stops and reducing the stopping distance.
- Improved weight distribution – The design of tandem axle trailers allows for better weight distribution of the load, reducing the strain on the towing vehicle and ensuring a more balanced load.
And for those planning to take on long-distance hauling or transport, tandem axle trailers provide a much safer and more stable option.
Tandem axle trailers overall allow for a larger and efficient towing experience which makes them a valuable asset for both commercial and recreational uses.
Disadvantages of a tandem axle trailer
While tandem axle trailers offer a range of benefits, including improved stability and increased load capacity, they do come with a few drawbacks. It’s also important to consider the possible disadvantages to make an informed decision if a tandem axle trailer is right for you.- Higher initial cost – Compared to single axle trailers, tandem axle trailers are generally more expensive to purchase brand new.
- Higher maintenance costs – It should be no surprise that with more wheels and bearing, the maintenance needs are heightened and therefore will require more servicing and check-ups to ensure everything’s up to standard.
- Increase in fuel consumption – Due to the increased weight of tandem axle trailers, they tend to consume more fuel compared to their single axle counterparts.
- Challenge in manoeuvrability – While they offer more stability, the extra axle can make them less manoeuvrable in tight spaces, making it difficult to navigate through narrow roads or parking in confined spaces.
- Increased tire expenses – With more tires in use, the chances of experiencing a flat or needing to replace tires are doubled, leading to increased operational costs over time.
Understanding the potential downsides of tandem axle trailers is key to making an informed purchase decision. When you consider both the advantages and disadvantages of a tandem axle trailer, only then will you get a better idea of whether it matches up to your trailer needs.
