D. Setting the field pour modules
1. The shoring timbers should be placed before setting scale modules. Using the
approach walls as the reference, place the shoring timbers so they will be at the
same elevation as the bottom of the weigh bridge. A tight string between the
approach walls could be used.
2. Install the modules as outlined in the previous sections of this manual, starting with
the center module.
3. Wedge additional shims as required under the end of the shoring timbers to ensure
tight contact between the scale frame and the shoring.
4. Pour the concrete. A spud-type vibrator is required to remove any air bubbles and
to work the material into all of the corners.
5. A rough "broom" finish is recommended. Crown the concrete 1 / 4 " to allow for
drainage. Allow the concrete to cure until the required minimum strength as
specified on the Certified prints is achieved.
6. After the concrete has cured, remove all of the shoring. The modules will have to be
lifted so the shoring can be removed.
7. Install the load cells in place of the locator tools.
* * Warning * *
The modules MUST be set on the locating tools. Do not support the load cell bracket with
lumber, as this will cause the module to twist or warp.
~Caution~
Make sure the edge beams of the scale are straight and not bowed down, or in, before
pouring the concrete deck. Do not install the load cells before the concrete deck is cured.
~Caution~
At the time the deck is poured, samples must be taken for later testing. At the end of 14 days,
test the first sample. A sample must pass the test at 4,000 psi before the scale can be placed
into service. A copy of the test report must be retained as part of the customer record in the
service center or distributor location otherwise warranty will be void.
* * Warning * *
Place hydraulic jacks ONLY at the CORNERS of the modules. Hydraulic jacks must be
placed on opposite sides to lift the module in a level position. Lifting mid span or between
load cells will cause cracks in the concrete.
