On-board Scale

For many types of trucks, knowing the loaded weight is important for operating safely and maximising payload whilst avoiding fines for overloading. There are two ways that a driver can determine the approximate loaded weight — either by driving to an in-ground scale, or using on-board scales. On-board scales use either load cell technology or pressure readings from air suspension to calculate the weight on the vehicle axles. Operating the truck at its optimal payload ensures that the owner minimises his running costs whilst maximising his profit.

The convenience of being able to weigh at the loading site is a key factor in the popularity of on-board scales. This ability eliminates the costs associated with using an in-ground scale, such as lost hours of service, scale fees, and driver wages.
