What Does Tandem Axle Mean?
Tandem refers to pairing two axles with wheels connected by a common suspension system — one in front of the other. For this reason, tandem axle trailers are also known as dual-axle or two-axle trailers. The configuration is especially useful for transporting heavy or oversized loads as it provides greater stability. Tandem axle trailers allow for a smoother ride and improved handling during transit than single-axel options.
How Does a Tandem Axle Trailer Work?
The tandem axle trailer works through the principle of load distribution. Each axle has its own set of wheels and tires, and they share the total weight of the trailer and its cargo. The size, type or number of axles often determines the amount of weight the trailer can handle and the vehicle’s load capacity.
The trailer’s main components include:
- Set of axles: Two axles allow for a more even weight distribution, offering better stability and minimizing wear on road surfaces due to reduced pressure. Spring and torsion axles are the most common types.
- Suspension system: The trailer’s suspension system connecting the axles plays a crucial role by absorbing shocks from road irregularities and keeping cargo stable. Some tandem axle trailers also feature equalizing suspension systems that adjust dynamically to uneven loads and road conditions, further enhancing stability and safety.
- Dual-break setup: With brakes on both axles, these trailers have advanced stopping power. The braking system offers better control, especially under heavy loads. Additionally, its dual-break setup allows for less brake wear and tear over time.
Tandem axle trailers leverage their dual-axle design, offering better load distribution, sturdiness and braking efficiency than their single-axle counterparts. These features make them invaluable tools for transporting large or heavy loads safely and efficiently.
How Much Does a Tandem Axle Trailer Weigh?
The weight of a tandem axle trailer will depend on its material, size and design features. An empty tandem axle trailer can weigh anywhere from 1,500 to 4,000 pounds. However, custom-built or specialized options may fall outside of this range. You must know the exact weight of your trailer to ensure compliance with vehicle towing capacities and road regulations.
How Much Can a Tandem Axle Trailer Carry?
The carrying capacity of a tandem axle trailer largely depends on its design and construction, though they’ll typically range from 7,000 to 12,000 pounds. When determining the weight your trailer can carry, consider the Gross Vehicle Weight Rating (GVWR) minus the weight of the empty trailer itself — also known as curb weight. Do not exceed this rating for safety and legal reasons.
How to Jack Up a Tandem Axle Trailer
Jacking up a tandem axle trailer requires careful steps:
- Collect the necessary tools: A regular bottle jack will not work since the larger tandem axle trailer weighs more than a single-axle model. Professionals typically recommend a tire ramp to jack up the trailer since it’s efficient and offers enough space to work without putting too much pressure on it. Also, gather a lug wrench, breaker bar, tire pressure gauge, socket and spare tire.
- Park the trailer on level ground: A smooth, level surface will ensure your trailer does not slide off the ramp. You might park it in a garage or parking lot to avoid traffic issues while working on it.
- Put your ramp in the correct position: Chock the trailer wheels opposite the side you’re lifting. This gives you a workable space. For example, if you were changing the front right tire of the dual axle, you’d position the ramp at the rear of the left back tire, with the low part of the ramp in the center of that rear tire.
- Elevate the trailer carefully: Place the jack under a solid frame area or designated lift point between the axles. Raise the trailer slowly until both tires are off the ground.
- Change the tire: Lift the trailer and remove the flat tire’s lug nuts. Replace it with a spare tire and tighten the lug nuts until they revolve. Slowly drive or back the trailer off the low end of the ramp.
To make the process as safe and smooth as possible, bring a person to help guide you. Be on the lookout for your surroundings, ensuring where you are working is secure.
Advantages of Tandem Axle Trailers
Tandem axle trailers offer various advantages, making them a preferred choice for casual and professional users. Here are some of the key benefits:
Enhanced Stability and Safety
With its additional axle design, these trailers offer better stability, especially at high speeds, reducing the risk of swaying and offering a smoother ride. With four tires on the ground and an enhanced suspension system, the trailer is safer for you and your passengers, providing better traction on slippery roads and even in the roughest weather conditions. Some people add sway control units to increase steadiness in windy areas and to protect cargo from excessive movement.
Easier Maneuverability
Tandem-axle trailers offer better maneuverability than single-axle trailers. Once you’re accustomed to the trailer’s size, navigating turns is much smoother with two axles. Their stability makes them easier to control on highways, with their wider turning radius reducing sway and offering swift transitions when turning. You’ll also have an easier time traversing uneven terrain, as the multiple axles provide better weight distribution, leading to improved traveling over bumps and dips.
Increased Load Capacity
Tandem axle trailers are designed to handle heavier loads than other trailers, making them ideal for hauling larger and bulkier items.
The increased weight capacity makes tandem axle trailers a good fit for commercial hauling, heavy equipment transport and extensive travel when carrying heavier cargo.
Better Weight Distribution
With two axles, tandem axle trailers spread weight more effectively over a larger area, ensuring a more balanced load. Even weight distribution places less stress on road surfaces, reducing road wear and minimizing the impact on the trailer’s tires and suspension components.
Better weight distribution can lead to lower maintenance costs and extended service life.
Improved Braking
Tandem axle trailers typically feature brakes on both axles, leading to superior stopping power, which is critical when transporting heavy loads. Improved braking also contributes to safety by reducing stopping distances and offering greater control when slowing down.
Fewer Tire Issues
With four tires on the ground rather than two, you get an extra layer of security in case one tire fails. Dual-axle trailers are also easy to change in the case of a blowout.
While a flat or blowout can be hazardous for any vehicle, having multiple tires on each side offers redundancy that allows you to safely pull over and address the issue. You might not even feel the effect of one flat tire.
Versatile Uses
Tandem axle trailers are highly versatile, offering a more efficient towing experience and making them a valuable asset for commercial or recreational use. Various industries, from construction to retail, leverage these trailers for hauling everything from raw materials to bulky furniture to heavy equipment.
Individuals can also leverage tandem axle trailers for diverse hauling needs, like moving boxes to a new house or hauling gear for a weekend getaway.
Resale Value
Due to their durability and versatility, tandem axle trailers typically retain their value better than others. They can handle heavier loads and offer better stability, making them attractive to a broader range of potential buyers in both commercial and recreational markets.
