For an Unlevel Concrete Floor Foundation:
Install threaded epoxy inserts or J-bolts in the foundation to support the base plates.
Place leveling nuts and washers beneath the base plates to adjust for level. Keep the
space between each base plate and the concrete floor to a minimum, and fill it with a
nonshrink, epoxy grout once all base plates are level and in the same plane (see Figure
10-5).
Figure 10-5: Base Plate Bolted to Unlevel Concrete Floor
For a Structural Beam Foundation:
Use through bolts, washers, and nuts to anchor the base plate to the flange of the
structural beam (see Figure 10-6). Install web stiffeners to prevent the beam from
twisting. If shimming is required to level the base plates or to keep them in the same
plane, add the shim beneath the entire base plate. If you are welding the base plates to
the beam, use a 3/8-inch fillet, 1 inch long on 3-inch centers.
CAUTION
DO NOT PASS WELDING CURRENT THROUGH THE LOAD CELLS! WHEN WELDING
ON A SCALE, ALWAYS GROUND THE WELDING DEVICE AS CLOSE TO THE WORK AS
POSSIBLE. NEVER WELD CLOSER THAN 4 FEET (1.2 METERS) TO ANY LOAD CELL
WITHOUT REMOVING THE LOAD CELL.
Note: If you use J-bolt anchors, you
will need to place them in the
concrete accurately before attaching
the weigh modules to the tank
supports. Make sure that the tank
support holes allow room for
adjustment so that the modules can
be aligned properly.
