There’s a few key numbers you need to know if you’re a trailer owner, and one of the most important is your trailer weight. Understanding the weight of a trailer is crucial for safe towing and compliance with legal regulations. Trailer weight impacts everything from towing capacity to fuel efficiency and overall vehicle handling. Here’s a comprehensive guide to help you understand the different aspects of trailer weight and why it matters.
Understanding the basics of Trailer Weight
The weight of a trailer can vary significantly depending on its type, size, and the materials used in its construction. Knowing the trailer weight in kg is essential for determining if your vehicle can safely tow it and for adhering to legal weight limits on roads. Trailer weight is typically measured in kilograms (kg), and there are several key weight terms you need to be familiar with.
What are the Key Weight Terms?
Tare Weight (Unladen Weight)
This is the weight of the trailer when it is empty, without any cargo. It includes all standard equipment and fluids but excludes any additional load. You can find the tare weight listed on the trailer’s compliance plate.
Gross Trailer Mass (GTM)
GTM is the weight of the trailer and its full load when it is attached to the towing vehicle. It is essentially the total weight that is transmitted to the ground by the trailer wheels.
Aggregate Trailer Mass (ATM)
ATM is the maximum weight of the trailer, including its full load, when it is not attached to the towing vehicle. This weight is typically specified by the trailer manufacturer and includes the tare weight and the maximum payload.
Average Weights of Different Trailer Types
It’s of course standard for different types of trailers to have different average weights. Here’s a look at some common trailer types and their typical weights:
- Small Box Trailers: These trailers are commonly used for light hauling and have a tare weight ranging from 150 to 300 kg. Their ATM can be up to 750 kg.
- Car Trailers: A car trailer is designed to transport vehicles and typically weigh between 700 and 1,200 kg when empty. Their ATM can be as high as 3,500 kg.
- Camper Trailers: These are popular for recreational use and vary widely in weight. Basic models can weigh around 500 kg, while fully-equipped versions can weigh up to 1,800 kg. Their ATM is often between 1,000 and 2,500 kg.
- Horse Floats: These trailers are designed for transporting horses and typically have a tare weight of 800 to 1,200 kg. Their ATM can range from 2,000 to 3,500 kg.
- Boat Trailers: Depending on the size and type of boat they are designed to carry, boat trailers can have a tare weight of 300 to 1,500 kg. Their ATM is generally between 1,500 and 3,500 kg.
Factors Influencing Trailer Weight
Several factors will influence the weight of a trailer, including its size, design, and materials used in construction. Larger trailers generally weigh more due to increased dimensions and structural components. The materials used, such as steel, aluminium, or composite materials, also play a part in determining the overall weight.
Importance of Knowing Your Trailer’s Weight
Knowing the trailer weight in kg is crucial for several reasons:
Towing Capacity
Your vehicle has a maximum towing capacity, which is the maximum weight it can safely tow. Exceeding this capacity can lead to mechanical failures and safety hazards. Always make sure that the combined weight of your trailer and its load does not exceed your vehicle’s towing capacity. For more information, check out our guide on towing capacity.
Compliance with Legal Limits
Different regions have legal weight limits for trailers to ensure road safety. Adhering to these limits helps avoid fines and ensures safe travel.
Fuel Efficiency
Heavier trailers can reduce your vehicle’s fuel efficiency, leading to higher fuel costs. Understanding your trailer’s weight can help you manage fuel consumption better.
Vehicle Handling
The weight of the trailer affects how your vehicle handles. Proper weight distribution is crucial to maintaining control, especially during turns and braking. For more details, read our guide on weight distribution trailers.
