How can a Single Load Cell Scale weigh a truck wheel the same on the outside of the platform as on the center of the platform when there is only one load cell in the scale weigh pad?
Torsion bars around the outside of the scale platform transfer the load so that the center load cell experiences the same weight no matter where the truck wheel is on the platform, as long as the wheel is fully on the platform. Offscale detectors detect if a wheel is not fully on the scale. If a wheel is detected as not fully on the scale, then the truck is directed to report to the static scale.
