2: For the end sections, the elevation reference is the end wall (approach) pit coping. Place
and clamp deck coping across the main beams at an end section facing the pit wall coping.
Adjust the load cell base plate leveling screws of both base plates in the end section to level
the approach as shown above. Ensure both base plates are also level to within 1/64” per
foot.
3: Proceed to the next section, which is a middle section. Ensure the hex bolts that connect
the top flexure plate to the support assembly stand are inserted but not completely tightened.
Ensure that the top bearing plate centers on the wear plate at each flexure, moving the entire
load cell support assembly on the base plate as required to accomplish this centering. Lower
the weighbridge onto the load cell support assemblies.
4: For the middle sections, the elevation reference is both the absolute level of the main
beams with respect to the end sections, and the equal loading of the loadcells that support
the middle of the scale. Adjust the load cell base plate leveling screws to level the main
beams. Alternately, a transit can be used to compare and maintain elevation, and a tightly
stretched mason line. Ensure both base plates are also level to within 1/64” per foot.
