3 - Types of Truck Scales Different truck scales are better suited for certain applications. The table below can help match your application to the right truck scale for you, taking into consideration cost, volume, and truck type.
Single-Axle Truck Scale
Full-Length Truck Scale
Multi-Axle Truck Scale
Weigh-In-Motion (WIM) Truck Scale
Overview
Similar to a full-length scale but same profile as a full-length scale but with one key difference: instead of intercon- nected modules and shared load cells, each module has its own cells. This allows for the scale to capture both full truck weight and individual axle weights.
In-ground single platform WIM scales capture axle weights while the vehicle is in motion and calculate a vehicles gross weight. WIM scales provide an efficient way to ensure that vehi- cles comply with local highway weight limits.
Composed of a single platform, large enough for a single set of truck axles. These cost-effective scales allow you to weigh each axle separately. In or- der to determine full truck weight, you then add all of the weights together.
Composed of multiple platforms that are connected together to accommo- date an entire truck. This is the most common type of truck scale set-up because most legal-for-trade rules specify that the entire truck be weighed at once.
Processing Speed
Lowest processing speed due to multi- ple stops by the truck
Medium processing speed due to only a single stop by the truck
Medium processing speed due to only a single stop by the truck
Fastest processing speed due to no stops by the truck

Additional Information
• Profile is ideal for sites with space restraints • Solution is not accurate enough for legal-for-trade weighing Single-axle scales are most often used to check compliance against lo- cal roadway limits
• Can be used bi-directionally for legal-for-trade weighing • Cannot capture individual axle weights Full-length truck scales are often used in applications that require a le- gal for trade transactions
• High performance due to more load cells being used in the system • Not designed for bidirectional weigh- ing Multi-axle scales are most often used to in legal-for-trade applications that also want to check for compliance against local roadway limits
• Profile is ideal for sites with space restraints • Solution is not accurate enough for legal-for-trade weighing WIM scales are most often used in applications with heavy truck traffic that require a compliance check against local roadway limits
Typical Application
Consideration for the Future Weigh-in-motion (WIM) solutions have traditionally been utilized by industries such as law-enforcement and logistics, but this technolo- gy is quickly advancing. For operations wanting to boost productivi- ty and throughput, certain WIM solutions could be a good fit. As regulations in legal-for-trade weighing progress, you can be pre- pared for the future by exploring WIM today.
