Crowning Instructions
Once the modules are in place and supported on dummy load cell stands or load cell
stands, you must verify that there is a positive crown in the modules. This is to ensure
proper rain and snow runoff. The same shoring timbers used for the bottom pan
support can be used for crowning the module. A laser transit or a string line can be
used to verify that a positive crown exists.
To use a string line, run a section of string from end to end of the module to ensure
that the center of the module is even or slightly higher than either end of the module. If
it is not, shims can be placed between the shoring timber and bottom of the module to
raise it slightly. The module can be lifted using bottle jacks. Be sure that blocking or the
shoring timber is in place to prevent the module from falling.
The width of the scale module must have a positive crown in the center as well. Stretch
a string across the width of the module to the outside edge of the beams. Again, the
center must be even or slightly higher than the outside edges. If it is not, additional
shims must be added between the shoring timber and center of the module. For 11’
wide and larger modules these would be placed under the two inner most beams. On
10’ wide modules this would be under the center connection plates.
The use of a pencil-type vibrator is required to ensure that the concrete is completely
under and encasing the 6” beams. This is what will give the modules their strength at
mid-span. Straight edge the cement by sections as shown below. Do not use a straight
edge that spans the entire width of the module.
