3.3 Mount and Installation Procedures
3.3.1 Positioning and Leveling the Mount, and Securing the
Retaining Plate
1. Start with a flat, rigid foundation (concrete pier). Using a forklift, position
the mount onto the foundation. Align the base plate in the direction of
travel (see page 6).
Note:
Leveling is the single most important part of the installation for
achieving high-accuracy weighing.
2. Adjust the leveling bolts to bring the top of the retaining plate up so it is
flush with the bottom of the scale deck I-beam. Check to see whether the
retaining plate is centered longitudinally with the scale deck I-beam and
adjust the mount if necessary. Place shims between the top of the retaining
plate and the bottom of the scale deck I-beam, because the scale deck I-
beam is never even. The shims should cover the entire surface to prevent
bending. If necessary, adjust the leveling bolts to insert the shims.
3. Using a high-quality bubble level, level the base plate within 0.2
°
of
horizontal to achieve a scale accuracy of 0.1% or better.
4. Mark the retaining plate hole locations on the scale deck I-beam (see
appendix for retaining plate hole dimensions).
5. Remove the load cell mount while noting the placement and height of the
shims.
6. With a magnetic drill, drill the holes into the scale deck I-beam.
7. Replace the mount and the shims. Bolt the retaining plate to the scale deck
I-beam. Retaining plate bolts are not supplied.
3.3.2 Securing Lateral Restraints
Lateral restraints (check rods) must be installed between each mount.
1. Install the check rods between each mount (see page 8). These lateral
restraints create a rigid mount system for heavy loading conditions. The
check rods should be positioned as close to each mount as possible. The rod
should be at least 4' to 6' long. Spherical washers should be used with each
nut.
