Installation
(12/99) 8-7
For a Level Concrete Floor Foundation:
Lower the weighbridge back onto the foundation so that the base plate mounting holes
line up with the holes that were drilled in the concrete. Insert a wedge-design expansion
anchor bolt into each base plate mounting hole (see Figure 8-6). Follow the anchor bolt
manufacturer’s instructions regarding the size and depth of holes and recommended
torque values.

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
8-7).

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 8-8). 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.
Note: If you use J-bolt anchors, you
will need to place them in the
concrete accurately before attaching
the weigh modules to the
weighbridge. Make sure that the
holes in the weighbridge’s support
points allow room for adjustment so
that the modules can be aligned
properly.
