Figure 2-13. Scale Carriage Location May Need Cross-Bracing
The idler spacing for the scale has been predetermined, and the three idlers before and after the scale should be
moved to match the same spacing.
Any splices in the conveyor frame work in the scale area are required to be permanently joined. Additional
bracing may be required under the conveyor frame work to minimize deflection and vibration under the load as
any additional bouncing will decrease the scale’s accuracy.
The 3rd idler before and the 3rd idler after the scale should be shimmed 1/4" higher than the adjacent idlers.
These will be the first and last idlers in the scale area.
The first and last scale idlers should be shimmed level across the conveyor. If the idlers adjacent to the scale area
are greater than 1/4" lower than the scale area, the adjacent idlers should be shimmed to ramp up to the scale area
in 1/4" increments.
Figure 2-14. Idlers Should be Level
The idler on the scale should be mounted to the scale weigh pads. The existing mounting feet should be removed
and the new feet welded on at the correct spacing for the pads.
Apply alignment string lines across the scale area idlers, stretching over the 3rd before and the 3rd idler after the
scale carriage.
