Wheel loader payload weighing and features
A wheel loader that weighs each bucket as it loads stops overloading and short loading at the source. How on board payload weighing works, the accuracy it reaches, and the productivity it adds.

A wheel loader filling trucks all day works on a knife edge between two costly mistakes: overload a truck and it risks fines, extra wear and having to dump material back off; underload it and you waste a trip and the truck leaves carrying air. For decades operators judged the load by eye and experience. On board payload weighing replaces the guess with a number, weighing the material in the bucket as it lifts, so every truck leaves at the right weight. It is a small feature with an outsized effect on a loading operation, turning a skilled estimate into a measured, repeatable result.
This guide is grounded in how the systems work and what they deliver.
Weigh the bucket, not the guess
On board payload weighing measures the material in the bucket as it lifts, so trucks leave at the right weight every time, not by the operator's eye.
How it works
The system reads the hydraulics. Sensors on the lift arms detect the small changes in hydraulic pressure as the bucket fills and raises, and that pressure correlates directly to the weight of the material. A cab display shows the weight of each bucket and runs a running total toward the truck's target, so the operator sees exactly when a truck is full.
Accuracy and tracking
Accuracy is good enough to rely on. Manufacturer systems quote figures such as around plus or minus 2 percent on one major brand and plus or minus 1 percent on another's on board weighing, when properly calibrated. Beyond the live weight, most systems track production: totals by operator, by customer, by job and by product, turning the loader into a measurement point for the whole operation.
| Feature | What it gives |
|---|---|
| Live bucket weight | See each load as it lifts |
| Target tracking | Fill to the truck's exact weight |
| High accuracy | Around 1 to 2 percent when calibrated |
| Production data | Totals by operator, job and product |

Using it well
- 1
Calibrate the system
Accuracy depends on proper calibration to the machine.
- 2
Set the targets
Enter the truck target weights to load to.
- 3
Load to the number
Fill to the target rather than by eye.
- 4
Use the data
Track production by job and product from the totals.
Calibration is what makes it true
An uncalibrated weighing system gives confident but wrong numbers. The accuracy figures only hold when the system is calibrated to the machine and the bucket, so calibration is part of the value, not a one off.
Our wheel loaders can come with payload weighing so your trucks leave correct and your production is measured. Tell us the operation and we will scope it.
