How do you determine axle load?

Determining axle load is a crucial task for many industries, especially in mining, transport, and construction. If you're managing heavy machinery or large vehicles, keeping track of the axle weight can save you a lot of money and prevent wear and tear on both equipment and infrastructure. So, how do you determine axle load? Let's break it down in simple terms, and along the way, we'll talk about how modern tech solutions like EYEMINE can help with this important task.

What is axle load?

The axle load refers to the weight that a vehicle’s axle carries. This weight is split between the front and rear axles of the vehicle. In simpler terms, it’s how much weight is resting on each axle of a vehicle. When you hear the term "gross vehicle weight" (GVW), it’s essentially the total weight of the vehicle, including everything it’s carrying. However, axle weight helps us understand how that weight is distributed across the axles.

Now, why does it matter? For one, improper axle loading can cause serious issues for both the vehicle and the road it’s travelling on. It can affect the vehicle's stability, cause tyre wear, and even lead to axle or suspension damage. That’s why monitoring axle weight is so important.

How do you determine axle load?

Determining axle load is actually a mix of science, technology, and a little bit of good old-fashioned weighing. Let’s take a look at some methods used for determining axle weight.

1. Weighbridge

The most straightforward way to determine axle weight is to use a weighbridge. A weighbridge is a large scale used to weigh trucks and other vehicles. It’s often found at mines, ports, and industrial sites.

Here’s how it works:

1. The vehicle drives onto the scale.
2. The vehicle is weighed to determine its total weight (GVW).
3. Then, the vehicle’s wheels or axles are individually weighed using special sensors under each axle.

By breaking down the total weight across the axles, you can determine the axle load for each axle of the vehicle. This is particularly helpful in the transport and mining industries where knowing the axle load is essential for safety and compliance.

2. Onboard weighing systems

Modern technology has made determining axle weight easier than ever. Onboard weighing systems are now common in mining trucks and other heavy-duty vehicles. These systems use sensors to measure the truck weight of each axle in real time as the vehicle is moving.

The benefits of onboard systems are clear:

• You get instant feedback on axle weight.
• You can ensure that the vehicle isn’t overloaded or underloaded while on the move.
• The data collected can be sent directly to a monitoring system, providing real-time insights into the vehicle’s performance.

In the mining industry, systems like EYEMINE Load + Haul Solutions help track the axle weight and monitor how well the vehicle is being utilised. These systems are integrated with software that provides accurate data on weight distribution and axle load, ensuring that vehicles operate efficiently and safely.

3. Load cells

For vehicles that are carrying loads on a regular basis, load cells are another way to determine axle weight. Load cells are sensors that can be attached to the vehicle’s axle or suspension. These sensors measure the amount of force or weight being applied, which is then converted into a reading of axle weight.

The cool thing about load cells is that they can be used in both dynamic and static environments, so whether the vehicle is in motion or stationary, load cells can provide accurate data.

4. Advanced truck and vehicle monitoring systems

In the modern world, companies like EYEMINE are revolutionising how we measure and manage axle load. With advanced monitoring systems, data on axle load can be gathered, processed, and analysed in real time. EYEMINE, for example, integrates a range of tools to track fleet efficiency, payload optimisation, and truck body evaluations.

Not only does this system measure axle load, but it also helps to monitor fuel consumption, carbon emissions, and other factors that impact the overall performance of the vehicle.

With the EYEMINE Load + Haul Solution, operators get access to critical performance insights such as:

• Real-time tracking of axle load.
• Truck weight analysis (gross and empty vehicle weight).
• Overload and underload analysis.
• Tyre load distribution.

This data-driven approach leads to more efficient operations, helping businesses save money by ensuring that vehicles are not overloaded and are running at optimal capacity.

Why monitor axle load?

Now that we’ve covered how axle load is determined, let's talk about why it's so important to monitor it.

1. Safety

Improper axle load can lead to unsafe driving conditions. Overloading an axle can cause the vehicle to become unstable, making it harder to control, especially on rough or uneven terrain. This can lead to accidents or equipment damage. Monitoring axle load ensures that vehicles stay within safe weight limits, reducing the chances of accidents.

2. Equipment longevity

If the axle load isn’t balanced or is too high, it can cause wear and tear on the vehicle’s suspension and tyres. This can shorten the life of the equipment and lead to costly repairs or replacements. By keeping track of axle load, you can avoid this unnecessary damage.

3. Compliance

In many industries, there are strict regulations about how much weight a vehicle can carry. Overloading a vehicle can result in fines and penalties. Using tools like EYEMINE’s Load + Haul solutions can help businesses comply with these regulations by accurately monitoring axle weight and preventing violations.

4. Cost-effective operations

When vehicles are overloaded, they burn more fuel, increasing operating costs. By ensuring that axle weights are properly distributed and that vehicles are not overloaded, you can optimise fuel consumption, reduce wear and tear, and increase efficiency. This leads to significant savings for businesses, particularly in industries like mining, where fleet management is critical.

5. Sustainability

Heavy vehicles that are overloaded produce more carbon emissions and consume more fuel. Monitoring axle load can help reduce the overall carbon footprint of your operations. With real-time data on axle load, companies can work towards achieving better environmental outcomes and reducing their emissions, which is becoming more important in today's eco-conscious world.

Determining axle load is a vital task in industries that rely on heavy vehicles, such as mining, construction, and transport. Whether through weighbridges, onboard weighing systems, or advanced monitoring software like EYEMINE Load + Haul solutions, having accurate data on axle load is key to ensuring safety, prolonging equipment life, complying with regulations, and improving operational efficiency.

By monitoring axle load, businesses can optimise their fleet’s performance, reduce costs, and contribute to a more sustainable future. So, the next time you're out on the road or managing a fleet, remember: axle load is not something you want to guess. Get the right tools to measure it, and the benefits will follow.
