3.02 Idler Preparation, WY Models
After finding a suitable location for the scale, reduce the conveyor belt tension. Raise the belt so
it is supported at least one foot above the idler where the scale will be located and also one foot
above the three idlers before and after the scale. Note, if you are installing a dual-idler scale
(model WY20 or WY25), follow the same instructions as for the single-idler scale (model WY10
and WY15) and just repeat the instructions for both idlers. Short conveyors might only have two
idlers on one or both sides of the scale, but this is not recommended because accuracy might
suffer. If this should occur, consult the
Tecweigh
service department for advice (Section 2.01).
DO NOT WELD ON OR NEAR THE SCALE!!!
1) Mark the center of each roller on the scale idler, three idlers before the scale, and three after
(see below).
2) Remove the idler where the scale will be located--this will be used as the weigh idler.
3) Remove the weigh idler's factory mounting pads.
4) Center the weigh idler on the unpainted scale mounting pads and mark the location on idler.
5) Remove the idler and the unpainted mounting pads from scale.
6) Weld the unpainted mounting pads to the idler at the previously marked locations.
7) Weld a reinforcement gusset in each corner of the weigh idler.
8)
Paint the weigh idler for corrosion prevention.
With the weigh idler modification complete, mount the idler on the scale using the four ½” bolts
provided. Center the idler on the scale as indicated below.
