What to Look for When Choosing a Lift Axle

If your trucking fleet needs lift axles, it’s essential to get them from a reliable manufacturer like Van Raden Industries. Based in Vancouver, Washington, we specialize in custom trailers, heavy-hauling trailer trucks, and the Flexmaster Lift Axle. In this blog post, we’ll explore the key factors to consider when choosing a lift axle. Keep reading to learn more.

Lift axles play a crucial role in trucks carrying heavy loads by evenly distributing weight. They are commonly used in dump trucks but also benefit concrete trucks, heavy vacuum trucks, refuse trucks, and water trucks—essentially any vehicle transporting significant weight.

These axles are often installed on trailers hauling heavy loads to comply with road and highway weight restrictions. Lift axles can be raised or lowered as needed, preventing unnecessary contact with the road and reducing fuel consumption.

If your trucking fleet frequently crosses bridges or other infrastructure, a lift axle is necessary due to legal requirements. Many states mandate the use of lift axles to ensure trucks adhere to weight limits, especially when traveling over bridges to prevent structural damage.

At Van Raden Industries, we offer Flexmaster Lift Axles for trucks. Some trucks can have lift axles installed during assembly, while others may require customization. If you’re in Vancouver, Washington, we can help you equip your truck with a Flexmaster Lift Axle. Before installation, it’s important to assess your vehicle’s weight distribution to ensure proper functionality and compliance with regulations.

Benefits of Trailer Lift Axles

• Smoother Ride: An extra set of tires underneath the truck can significantly improve the driving experience, especially on unpaved roads. Lift axles help stabilize heavy loads, preventing them from shifting during transport.
• Increased Load Capacity: More tires and axles beneath a heavy load allow for better weight distribution across the trailer. This reduces strain on individual tires and improves the trailer’s ability to carry heavy loads. However, weight limit regulations vary by state, so if you’re transporting goods across state lines, you must comply with these laws to avoid fines for both the driver and the company.
• Improved Fuel Efficiency: When not in use, a lift axle can be raised, reducing drag on the trailer. With less resistance, the truck requires less horsepower to move, leading to lower fuel consumption. This is especially beneficial for truck drivers who pay for their own fuel, as it translates to cost savings.
• Reduced Wear and Tear: Lift axles help extend the lifespan of a truck’s components in two ways. When carrying a heavy load, they distribute weight evenly, reducing strain on tires, axles, wheels, and the suspension system. When the axle is not needed, it can be raised, preventing unnecessary contact with the road and minimizing wear on the tires and engine.
• Less Road Impact: Lowering a lift axle can help absorb the impact of a heavy load on the road. Conversely, when the truck is empty, raising the axle reduces the surface area in contact with the road, decreasing tire friction and overall wear.
• Lower Tolls: Some states offer toll discounts for vehicles with adjustable axles on highways and bridges. This makes lift axles a cost-effective investment for trucking fleets while also reducing road damage and maintenance costs.

Important Factors to Consider When Choosing a Lift Axle

State Laws and Regulations

Different states and federal highways have weight limits and regulations on how much weight a truck can legally transport. Before installing a lift axle, check with your local authorities and review bridge laws in your area to ensure compliance.

Placement and Type of Axle Needed

Determine where your truck requires additional load-carrying capacity—whether at the rear or middle of the vehicle. Proper placement is crucial for maintaining balance and ensuring optimal performance.

Chassis Space and Installation Requirements

Consider whether there is enough room on the chassis to accommodate a lift axle. If your truck does not already have an auxiliary axle, you may need a truck shop, builder, or upfitter to install it. Components such as air tanks, crossmembers, fuel filters, or fuel tanks may need to be relocated. Proper spacing must be planned according to legal requirements, so it’s essential to work with a qualified professional.

Number of Axles Needed

The number of lift axles required depends on the length of your truck and the weight distribution of your load. Some trucks may require just one or two axles, while others can accommodate up to four auxiliary axles.
