Truck scales (US) or weighbridges (non-US) are large scales that are usually mounted permanently on a concrete foundation weighing scale that are used to weigh entire vehicles and their contents. By weighing the vehicle both empty and when loaded the load carried by the vehicle can be calculated. Truck scales can be surface mounted with a ramp leading up a short distance and the weighing equipment underneath or they can be pit mounted with the weighing equipment and platform in a pit so that the weighing surface is level with the road. They are typically built from steel or concrete and by nature are extremely robust. In earlier versions the bridge is installed over a rectangular pit that contains levers that ultimately connect to a balance mechanism. The most complex portion of this type is the arrangement of levers underneath the weigh bridge since the response of the scale must be independent of the distribution of the load. Modern devices use multiple strain gauges that connect to electronic equipment to totalize the sensor inputs.
