Abstract
A truck scale has a weighbridge built with two parallel beams for carrying the wheels of a truck. The beams are laterally interconnected, and are each narrower than half the width of the weighbridge, so there is a gap at the center between the beams. Each beam rests directly on load cell devices supported by foundation members. In very long scales each beam is composed of shorter sections, each supported by a pair of load cell devices. The gap in the center of the weighbridge is covered by removable cover plates or blocks, which may have side walls extending above the beams to limit the lateral travel of truck wheels on the scale.
