How to Install a Farm Weighbridge

What is a Farm Weighbridge?

A farm weighbridge is a device used to measure the weight of animals, vehicles, and other objects brought onto a farm. These devices can be found in many agricultural settings and serve multiple purposes. They are often used for tracking livestock weights, calculating loads on trailers or carts, monitoring vehicle traffic flow, and providing accurate measurements for feed rations.

These weighbridges are essential for farmers by ensuring that their livestock and vehicles remain within safe weight limits while also helping them to manage their resources more efficiently. The most common type of farm weighbridge is the truck scale system, consisting of one or more steel platforms supported by load cells beneath the surface.

The platforms have been designed to accurately measure individual axle weights and total vehicle weights up to 80,000 Kg (72 metric tonnes). This makes it possible to precisely monitor the amount of material being loaded onto trailers or carts so that they do not exceed legal limits when travelling from one location to another.

So, how are these weighbridges installed in farms and agricultural businesses?

How to Install a Farm Weighbridge

Installing a farm weighbridge can be a significant investment that benefits your agricultural operations. Here is a step-by-step procedure to guide you through the installation process.

Step 1: Determine the Location

Selecting the right location for your farm weighbridge is crucial. Look for an area that is accessible, level, and can accommodate the size of the weighbridge. Ensure the ground is solid and capable of supporting heavy loads consistently without sinking or shifting.

Step 2: Obtain Necessary Permits and Approvals

Check with your local councils to understand the permits and approvals required for installing a weighbridge on your farm. This step ensures that you comply with any regulations or restrictions that may be in place.

Step 3: Prepare the Foundation

Preparing a solid foundation is essential to ensure the accuracy and longevity of your weighbridge. Excavate the area, remove debris or obstructions, and level the ground meticulously. Compact the soil thoroughly to create a stable base, ideally using a vibrating roller or plate compactor.

Step 4: Construct the Foundation Slab

Next, construct a reinforced concrete foundation slab on the prepared ground. Follow the specifications provided by the weighbridge manufacturer to ensure the slab meets the required strength and thickness. Reinforcement bars and a suitable concrete mix are necessary for durability and load-bearing capacity.

Step 5: Allow the Foundation to Cure

After pouring the concrete, allow it to cure properly. Curing time will vary depending on environmental conditions and the concrete mix used. Adequate curing is vital to achieve the desired strength and prevent later cracking or structural issues.

Step 6: Install the Weighbridge Structure

Once the foundation is fully cured and hardened, it's time to install the weighbridge structure. Typically, this involves positioning the prefabricated weighbridge modules onto the foundation and securely bolting them together. Follow the manufacturer's instructions carefully to ensure accurate alignment and proper installation.

Step 7: Connect the Load Cells and Electronics

The load cells are crucial components that measure the weight on the weighbridge. Connect them to the weighbridge structure per the manufacturer's guidelines, ensuring they are correctly mounted and aligned. Following the wiring diagrams, install the associated electronics and cabling, including indicators, terminals, and junction boxes.

Step 8: Calibrate and Test the Weighbridge

Before putting the weighbridge into full operation, it is essential to calibrate and test its accuracy. Engage a professional weighing service provider or technician to verify the calibration and perform test weighings using known weights. Adjustments can be made to ensure the accuracy and reliability of the weighbridge readings.

Step 9: Provide Adequate Lighting and Signage

Ensure the weighbridge area is well-lit to facilitate operations during various times of the day or night. Install appropriate lighting fixtures that cover the entire weighbridge area, including access ramps and surrounding areas. Additionally, place clear and visible signage to guide users and communicate safety instructions or precautions.

Step 10: Establish Maintenance and Cleaning Procedures

Establish regular maintenance and cleaning procedures to maximise your farm weighbridge's lifespan and functionality. This includes inspecting load cells, cleaning the weighbridge surface, and ensuring the surrounding area remains debris-free. Regular maintenance will help identify any potential issues and allow for timely repairs.


By following these step-by-step procedures, you can successfully install a farm weighbridge.
