What is an 'over-the-road' truck scale? 

A truck scale that is used for over-the-road purposes must meet certain capacity, accuracy, and durability requirements. These scales will only ever have to weigh trucks which drive over the public road. This means the scales will not have to handle large off-road vehicles such as mining trucks, etc. The truck scale should also meet the accuracy requirements to determine if a truck meets the legal over-the-road limits for that region. Finally, these types of truck scales should be prepared to handle a high level of traffic as they can see high volumes of trucks depending on the operation.

What kinds of over-the-road truck weighbridges are available?

Truck weighbridges typically come in two distinct offerings: concrete deck or steel deck. The decision of scale deck is up to the specific operation and its needs. Some considerations include:

  • Concrete deck has a longer wait time to a working scale because concrete typically takes up to 30 days to set
  • Concrete deck and steel deck can be effected in different ways by corrosive material. Salt for example is bad for concrete. But certain chemicals can erode steel. The application should be considered for this reason.
  • Concrete can generally provide more grip in slick environments. For this reason, areas that get a lot of rain, snow, or ice can sometimes prefer concrete decks. This is relevant both for the truck tires gripping the bridge and for operators who may have to get out of their trucks to complete transactions.
