Abstract
Abstract A flat weighbridge has a load platform supported by either two one-armed or two two-armed levers arranged at least partly beneath the load platform, wherein one lever is bifurcated to define two spread apart sides and each of the sides bears a supporting device for the load platform, while the other lever bears only one supporting device for the load platform.
