Axles for lowbed trailer

Types of Axles for Lowbed Trailer

Axles for lowbed trailer are a crucial part of heavy-duty transport vehicles. The lowbed trailer axle is a beam or shaft that connects the wheels or wheel hubs. It serves as a support for the trailer load. The axle for the lowbed trailer also serves as a track for the lowbed trailer steering. Generally, lowbed trailers have two or more axles. Depending on the design, some trailer axles are fixed to the lowbed trailer body, while others can be detached. There are various types of lowbed trailer axles. Here are some of them:

• Drop Axle for Lowbed Trailer

  The drop axle is a popular choice for a lowbed trailer. The drop axle features a design style where the wheel spindles are located below the centerline of the axle beam. This unique design drops the trailer height. As a result, the lowbed trailer can transport loads that have a greater height clearance. The drop axle also features a higher load capacity. The load capacity of the drop axle makes it suitable for transporting heavy equipment and oversized loads. The drop axle is commonly used for lowbed trailers with 4 to 10-axle configurations.

• Parallel Axle for Lowbed Trailer

  The parallel axle is a conventional axle design. It features an axle beam built parallel to the trailer's road surface. The parallel axle helps to keep the wheels perpendicular to the trailer for stable wheel movements. This axle design for the lowbed trailer enhances load distribution and offers a smoother ride. The parallel axle is a common choice for lowbed trailers ranging from 2 to 6 axles.

• Independent Suspension Axle for Lowbed Trailer

  The independent suspension axle is another axle design for the lowbed trailer. Each wheel is independently attached to the lowbed trailer through an individual suspension system. This design allows each wheel on the lowbed trailer to move independently. As a result, the independent suspension axle improves the stability and traction of the lowbed trailer. The independent suspension axle is a suitable choice for lowbed trailers used for long-distance transport of goods.

• Tandem Axle for Lowbed Trailer

  The tandem axle is a common axle configuration. It features two axles placed close together on the same lowbed trailer axle assembly. This design doubles the load capacity and improves the stability of the lowbed trailer. The tandem axle configuration is often used for lowbed trailers with 5 or more axles. The tandem axle is suitable for transporting heavy loads and oversized equipment.

Specification and Maintenance of Axles for Lowbed Trailer

The specifications of a lowbed trailer axle are as important as the trailer itself. This is because the axles for lowbed trailers bear the weight of the trailer. Here are some of the factors that affect the specification:

• Weight Capacity: The lowbed trailer axle should be able to handle the weight of the transport equipment and more. For example, if the transport equipment weighs 60 tons, the axle should have a capacity of at least 70 tons. This is to cater for emergencies like accidents where the trailer can tip over.
• Design: The lowbed trailer axle can either be a conventional or a beam axle. The beam axle is usually for heavy-duty trailers. This is because it has a single steel beam that connects the wheels.
• Material: Axles for lowbed trailers are made using strong materials like steel. The steel is treated to make it harder and more suitable for the lowbed trailer. The axles can also be made of aluminum. Aluminum axles are lighter and more suitable for light lowbed trailers.
• Size: The size of the lowbed trailer axle determines its capacity. The length is measured from the wheel center to the wheel center. The size of the axle is also affected by the lowbed trailer size.

Lowbed trailer axle maintenance is important in order to avoid accidents and lowbed trailer breakdowns. Here are some of the lowbed trailer axle maintenance tips.

• Regular Inspection: The lowbed trailer axle should be regularly inspected to check for any signs of damage or wear. The inspection should check the wheels, wheel bearings, and the axle itself.
• Proper Lubrication: The lowbed trailer axle wheel bearings should be properly lubricated to reduce friction. This makes it easier for the wheels to rotate, which reduces wear and tear.
• Weight Management: The lowbed trailer should not exceed its weight capacity. This is because overloading the trailer puts a lot of stress on the axle. The weight of the load should be evenly distributed across the trailer.
• Replace Worn Parts: Any parts of the lowbed trailer that are worn out should be replaced immediately. This prevents the wear and tear from affecting other parts of the trailer. The axle should also be replaced if it is damaged beyond repair.

How to Choose Axles for Lowbed Trailer

Choosing the right axle for a low bed trailer is vital to ensure safety and increase efficiency when transporting heavy loads. Here are some factors that businesses should consider when choosing axles for lowbed trailers.

Firstly, consider the lowbed trailer axle capacity. The axle capacity is very crucial because it determines the amount of weight the axle can carry without damage. The axle capacity should be higher than the total weight of the load to be transported. To get the axle capacity, divide the lowbed trailer gross weight by 2 to get the axle load on each side. Ensure that the axle chosen has a higher value than the calculated axle load.

Next, consider the lowbed trailer axle size. The size of the axle plays a very important role in the performance of the trailer. A larger axle supplies more power and gives more strength to carry heavier loads. A lowbed trailer with larger axles offers more stability and reduces the risk of accidents when transporting heavy loads. However, the larger axles make the trailer heavier and affect fuel efficiency.

Another factor to consider is the lowbed trailer axle suspension system. This is because the suspension system affects the stability of the trailer and the axle's life. A lowbed trailer with a good suspension system absorbs shock and impact, thereby reducing the strain on the axle. There are different types of suspension systems, such as air suspension, tandem suspension, and single suspension. Choose the right suspension system according to the load capacity and the terrain of the road.

Additionally, businesses should consider the material used in making the trailer axle. Axles are commonly made with steel, although some manufacturers use aluminum. Steel is the best material for lowbed trailer axles because of its strength and durability. Axles made of aluminum are lighter, but they wear out quickly and are not suitable for transporting heavy loads.

Finally, choose the right axle ratio. The axle ratio is the number of rotations the trailer wheels make compared to the number of rotations the axle makes. A higher axle ratio means higher torque, while a lower axle ratio means higher speed. Choose the right axle ratio based on the type of load and the terrain.

How to DIY and Replace Axles for Lowbed Trailer

Replacing an axle on a lowbed trailer is a complex task that requires mechanical expertise. Here are the general steps taken to replace an axle on a lowbed trailer:

• Gather necessary tools: Socket set, wrenches, jack stands, hydraulic floor jack, new axle assembly, and safety glasses.
• Park the lowbed trailer on a level ground and engage the parking brakes. This will ensure that the trailer doesn't move in the process of replacing the axle.
