WHAT YOU NEED TO KNOW ABOUT 40 FT GOOSENECK TRAILER WEIGHT

26 Mar, 2025

The weight of a 40 ft gooseneck trailer is a key factor for safe and efficient transport. A 40 ft gooseneck trailer can weigh between 9,630 lbs to 25,000 lbs depending on its production material, number of axles, as well as additional options. In this article, Thaco Trailers will explore the main factors that influence the weight of a 40ft gooseneck trailer and how to determine the weight of this trailer.

How much does a 40 ft gooseneck trailer weight?

A 40-ft gooseneck trailer typically weighs around 9,630 lbs when empty and can tow up to 25,000 lbs when carrying heavy loads. However, the actual weight may vary depending on factors such as the construction material (steel or aluminum), suspension system, number of axles, and additional features.

Factors affecting the weight of 40ft gooseneck trailer

Materials

Steel: Steel trailers are generally heavier than aluminum trailers, but they offer greater durability and strength, making them suitable for heavy-duty applications. The added weight increases hardness, rigidity, and load-bearing capacity, which is beneficial in applications where the wheels face significant stress. However, the added weight can cut down payload capacity which gives importance to the trailer’s material when choosing for some carriage purpose.
Aluminum: Light aluminum trailers are used in preference to the heavy steel ones because they improve fuel efficiency, and increase the trailer’s payload capacity. This is particularly beneficial in industries where sparing towing weight is of essence in order to maximize the load and minimize fuel consumption. However, aluminum is known to be less strong than steel, and it can also get damaged easily, especially when exposed to very hard impacts and conditions.

Trailer Dimensions:

Length and Width: The average gooseneck trailer measures 40 ft in length, 8.5 ft in width, and 8 to 9 ft in height, depending on the type. These dimensions play a crucial role in determining the trailer’s weight, as larger trailers are generally heavier than smaller ones.
Height and Deck Thickness: The average gooseneck trailer stands between 8 to 9 ft in height, with deck thickness varying based on load capacity and material. A higher-profile gooseneck may require thicker tubing for added strength, increasing the overall weight. Additionally, a thicker deck is often necessary to support heavier or specialized loads, ensuring stability and safety during transport.

Added Features:

Suspension System: The suspension system plays a crucial role in determining a trailer’s weight. Air ride suspension, known for its superior ride quality and load stability, is particularly valued for its ability to absorb shocks and ensure smoother transport for delicate cargo. However, compared to other suspension types, air ride systems are heavier and more complex.

Axles: Another factor affecting a trailer’s weight is the number and type of axles. A single-axle trailer is typically lighter than a tandem or triple-axle trailer, as adding more axles increases the overall weight.

How to determine the weight of a 40ft gooseneck trailer?

Using a Weight Scale

One of the most reliable methods to determine the weight of a 40ft gooseneck trailer is by using a certified weight scale, commonly found at truck stops or official weighing stations. Follow these steps:

Step 1: Weigh the Towing Vehicle Alone

Drive the towing vehicle onto the scale without the trailer attached. Record its weight to establish a baseline.

Step 2: Weigh the Towing Vehicle with the Trailer

Next, drive both the towing vehicle and the 40ft gooseneck trailer onto the scale. Record the combined weight.

Step 3: Calculate the Trailer’s Weight

Subtract the weight of the towing vehicle (Step 1) from the total combined weight (Step 2). The result gives you the exact weight of the trailer.

This method ensures accurate weight measurement, which is crucial for complying with legal towing regulations. Exceeding road weight limits can result in violations and fines, making it essential to verify the trailer’s weight before transport.
