  • Portable pallet weighing apparatus
    Patent number: 4479560
    Abstract: An assembly (10) for use with several like units in weighing the mass of a loaded cargo pallet supported by its trunnions (12) has a bridge frame (20) for positioning the assembly on a transportation frame carrying the pallet while straddling one trunnion of the pallet and its trunnion lock, and a cradle assembly (60) for incrementally raising the trunnion. The mass at the trunnion is carried as a static loading by a slidable bracket (40) mounted upon the bridge frame for supporting the cradle assembly. The bracket (40) applies the static loading to an electrical load cell (80) symmetrically positioned between the bridge frame (20) and the bracket (40). The static loading compresses the load cell, causing a slight deformation and a potential difference at load cell terminals (86) which is proportional in amplitude to the mass of the pallet at the trunnion.
