CONVEYOR WEIGH SCALE
3-0 WEIGH SCALE ASSEMBLY
3-1)
The weigh scale troughing idler must be modified prior to clamping it to SYSTEMS’ weigh scale frame. See
procedure on drawing # WB00-00005 ’Suggested Rework’. Complete modification as shown.
3-2)
Assemble weigh scale, independent of conveyor in the following order. See drawing # WB00-00004 ’Weigh Scale
Mounting Assembly for Field Installation."
3-2A)
Mount load cell (Cable End) to welded frame assembly with (4) 5/16 x 1 1/4’ hex bolts and washers. (Mating
surfaces must be clean and free of foreign materials.) Torque bolts to 100-120 in/lb.
3-2B)
Place 1/2" spacer on load cell. (Mating surfaces must be clean and free of foreign materials.)
3-2C)
Carefully set 7’ channel on 1/2’ spacer centered on weigh bridge assembly. (Mating surfaces must be clean and
free of foreign materials.)
3-2D)
Secure channel to load cell with (4) 5/16 x 1 1/4 hex bolts and washers. Center channel side to side on weigh
scale frame. Torque bolts to 100-120 in/lb.
Note: Carefully handle weigh scale assembly to avoid shock that may damage load cell.
3-2E)
Center modified idler on the channel. Install V-block clamping assembly (2 places), using (4) 1/2 x 2 1/4’ hex bolts
with lockwashers. Tighten securely.
4-0 WEIGH SCALE INSTALLATION and PRELIMINARY ALIGNMENT
4-1)
Install complete weigh scale assembly in the intended position on conveyor. Using weigh scale as template,
carefully locate, mark, and drill (4) 9/16 dia. holes in conveyor frame.
4-2)
Mount the weigh scale in position using (4) 1/2 x 2 1/4’ bolts with lock and flat washers. Install 3/8" of shims
(supplied with weigh scale) below weigh scale mtg angles. Hand tighten bolts at this time. (Mating surfaces must
be clean and free of foreign materials.)
4-3)
Shim the approach and retreat idlers to approximately the same height as the weigh scale idler.
Note: The approach, retreat and weigh idler must all be higher than all the other conveyor idlers.
