2.0 Assemble Deck Modules
The modules are designated either as an end module
or a center module. All two-module scales will have
two end modules, while longer scales will have two
end modules and one or more center
module (see
diagram below).
Figure 2-1. Center and end modules.
In a three module scale, the end module is the first to
be positioned on setting blocks followed by the center
module. The last module to be assembled is an end
module. Scales with more than threee modules will
have additional center modules installed. As an
example, a 100' scale would have two end modules
and three center modules.
2.1 Place End Module A
Place one 12-1/4" temporary setting block on the top
of each pier and position them so that they will not
interfere with the installation of the load cell mounts.
The scale module should be 3/4" away from the
bulkhead ramp and 3/4" from each pit wall side (see
figure on right). By using the 12-1/4" blocks, the top
of the main beam will be approximately 6-1/3" below
the top of the pit.
2.2 Place and Attach Center Module
NOTE:
To assist in easy assembly of the center module, make
sure that both modules have direct end-to-end surface
contact.
1. Place four 12-1/4" setting blocks on top of the
piers in the center sections.
2. Position and place the center module on the
setting blocks, making sure that both the end
module and center module end plates are
aligned.
3. Check that the module is centered side-to-side
in the pit.
NOTE:
At the installer’s discretion, install the center section
with the J-box on the near side to the scale house.
4. When both modules are aligned, insert the top
three 1-1/8" bolts with flat washers, lock
washers and nuts on the outside of the beam.
(Leave out the bottom bolt to facilitate load
cell mount installation).
NOTES:
•
Tighten bolts and nuts finger tight until all modules
are in place.
•
A long pry bar can be used to make small
adjustments in module alignment, but it is easier to
leave the second module attached to the crane for
making small alignment changes.
5. Install the three top bolts, washers and nuts on
the inside of the beam. Install the bolts,
washers and nuts on the opposite beam using
six bolts, washers and nuts. Tighten only
finger tight.
NOTE:
Do not install the bottom bolt at this time.
Figure 2-2. Top bolts, washers, and nuts installed.
6. If required, place and install any additional
center modules in a similar manner.
7. Install the remaining end module on four
setting blocks ensuring the end beams are
aligned with and in direct surface contact with
the center module.
Figure 2-3. Module installation.
8. Center the module side-to-side and check that
the end of the main beam is 3/4" from the end
of the concrete pit wall. Install and tighten the
three top bolts on each beam (inside and
outside) finger tight as in the previous
operation.
NOTE:
Do not install the bottom bolt at this time.
