On-board scales for dump trucks are essential tools for ensuring efficiency, productivity, and safety in hauling operations. These systems allow operators to monitor the load weight in real time, which is critical for staying within weight limits, optimizing payload, and improving fuel efficiency. But with various on-board scale options available, it can be challenging to decide which system works best for your dump truck. This article will explore the key considerations when selecting on-board scales, examine different types of systems, and highlight some top solutions based on user experiences.

Many dump truck operators have shared their experiences with different on-board scale systems, highlighting how these tools have helped improve their operations. For example, a construction company based in Arizona implemented a Raven ScaleTec system on its fleet of dump trucks. According to the company’s fleet manager, the scales have significantly reduced the number of overloaded trucks and helped them avoid costly fines from weight violations.
Another operator in the Midwest reported that after switching to a TruckWeigh system, the company was able to reduce fuel consumption by ensuring that trucks were loaded optimally without exceeding weight limits. This improved efficiency led to fewer trips and better cost control over time.
Conclusion
Choosing the right on-board scale system for your dump truck is a critical decision that can significantly impact your operations. Whether you opt for a hydraulic pressure-based system, load cells, or strain gauges, each system has its pros and cons. Accuracy, durability, ease of installation, and cost are all important factors to consider.
By selecting the best on-board scales for your needs, you can ensure that your trucks are operating efficiently, safely, and within legal weight limits. This not only improves productivity but also reduces the risk of fines and costly repairs, ensuring the long-term success of your business.
Why On-Board Scales Are Important
On-board scales provide a crucial function in the trucking and construction industries. Their primary purpose is to measure the weight of the load in real time, which offers multiple benefits:
- Avoid Overloading: Exceeding weight limits on roads and highways can result in hefty fines, damage to the truck, and compromised safety. On-board scales ensure the truck is loaded within safe weight limits.
- Efficiency and Productivity: By accurately gauging the weight of each load, operators can optimize the truck's payload. This prevents underloading or overloading, both of which can waste time and fuel.
- Cost Savings: Better management of payloads reduces the risk of fines and minimizes wear and tear on the truck, ultimately saving money on maintenance and fuel.
- Improved Safety: Correct weight distribution ensures better handling, braking, and control of the vehicle, thus enhancing safety for both the driver and other road users.
- Inventory and Reporting: On-board scales can also help with inventory tracking and reporting, as they provide precise records of the weight of loads being transported.
There are several types of on-board scales available for dump trucks, each with its own advantages and drawbacks. Let’s take a closer look at the most common types:
- Hydraulic Pressure-based Systems: These systems measure the hydraulic pressure in the lift cylinders and use this data to estimate the weight of the load in the dump body. Hydraulic pressure-based systems are commonly used in smaller dump trucks.
- Pros: Simple to install and often less expensive than other systems.
- Cons: They may not be as accurate as load cells and can be influenced by hydraulic system wear or pressure fluctuations.
- Pros: Simple to install and often less expensive than other systems.
- Load Cell Systems: Load cells are devices that directly measure the weight of the load on the truck. These are commonly installed in the suspension or under the dump body to provide highly accurate weight readings.
- Pros: Accurate and reliable weight measurements, less affected by hydraulic or system changes.
- Cons: More expensive than hydraulic pressure-based systems, requires precise installation.
- Pros: Accurate and reliable weight measurements, less affected by hydraulic or system changes.
- Strain Gauge-based Systems: These systems use strain gauges to measure the deformation of the truck’s frame or suspension system. When the truck is loaded, it deforms under the weight, and the strain gauges calculate the weight.
- Pros: Accurate and easy to install without the need for modifications to the truck’s structure.
- Cons: Less reliable when there are significant changes in the truck’s structure over time, such as from wear or repairs.
- Pros: Accurate and easy to install without the need for modifications to the truck’s structure.
- Weighing in Motion Systems: These systems use sensors installed along the truck’s path (usually in the pavement or ground) to weigh the truck as it drives over them.
- Pros: Can provide weight measurements without requiring the truck to stop or unload.
- Cons: Can be expensive and require specialized infrastructure, such as sensors embedded in roads or weigh stations.
- Pros: Can provide weight measurements without requiring the truck to stop or unload.
When deciding which on-board scale system works best for your dump truck, several factors should be considered:
- Accuracy: The most critical factor when choosing an on-board scale is accuracy. Load cells typically offer the best accuracy, but other systems, such as hydraulic pressure-based scales, may be adequate depending on the needs of the operation.
- Cost: On-board scales can range from budget-friendly options to more expensive systems. Hydraulic pressure-based systems are often the least expensive, while load cell and strain gauge systems tend to be pricier due to their higher accuracy and reliability.
- Ease of Installation: Some systems, like hydraulic pressure-based scales, are easier to install, while others, such as load cells or strain gauges, may require modifications to the truck’s suspension or structure.
- Durability: Given the harsh environments dump trucks work in, the durability of the scale system is crucial. Look for scales that are resistant to dust, moisture, and vibration, as well as those that are built to withstand the heavy demands of hauling.
- Maintenance: The more complex the system, the more maintenance it will require. Hydraulic systems may need regular checks for pressure consistency, while load cells and strain gauges should be inspected for wear and tear, particularly after long periods of heavy use.
- Integration with Other Systems: Many on-board scales can integrate with other fleet management systems, including GPS tracking and load optimization software. This can make it easier to manage and track operations remotely.
Several manufacturers offer on-board scale systems for dump trucks. Here are some of the most popular solutions:
