Load Scanners vs Onboard Weighing

What are the Pros and Cons?

The days of guesstimating truck weights or driving to weigh bridges is over. Load scanners and onboard weighing have revolutionised the way we do business, but which type is better?

Before you make any decisions, it’s best to “weigh up” (see what we did there!) some of the pros and cons. Let’s take a look at the differences between load scanners and onboard weighing systems.

What is a load scanner?

Load scanners calculate real-time load volumes for trucks in motion. Trucks are scanned while empty, and these loadscans are saved in the system. Once loaded, the system scans and calculates the volume of carried material, which it does by comparing the loaded scans to the stored empty scans in the system. It comprises 3D laser scanners, a laptop or PC, and mounting hardware.


Real time load measurement
Cloud-based reporting
Generates 3D imagery to assess load positioning
Advanced tracking capabilities
Can take and store high definition images


Must be hard mounted
Requires a dedicated scanning site with adequate access

What is onboard weighing?

Onboard weighing systems are fitted to individual vehicles, as opposed to fixed location equipment like weigh bridges. There are a variety of systems to suit different machines (including light commercials and vans), allowing loads to be weighed in real time as they are loaded. They take the guesswork out of weight measurements - ensuring accuracy - and can report data in real time.


Real time load measurement
Advanced tracking capabilities 
A variety of digital and printed reporting options
Can be used on any terrain - rough, smooth, wet or dry
No time wasted driving to weigh bridges or scanners


Does not specify load positioning
Does not record images 

While load scanners and onboard weighing systems both demonstrate a proven track record when it comes to accuracy, the onboard systems maintain a slight competitive edge because they are fitted and calibrated to the actual vehicle. This means you can weigh your loads right on the spot - in any sort of terrain - without the need for a dedicated trip to drive through a scanning site. This means you can be up and on your way in an instant.
