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

6-5).

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 6-6). 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.

After securing all the top plates and base plates, slowly back out the nut and

centering washer on each hold-down bolt, carefully lowering the top plate and

weigh structure onto the load cells.

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.
