Adjusting the Scale after the Pour
1. Once the deck is complete, set the side and end checking to desired gaps.
2. Install load cells under main girders and position the base plates so that each
load cell is plumb. See Installing Load Cells section on next page.
3. Drill and insert anchor bolts through the holes in each base plate. Install clamp
bars, washers, and finger-tighten bolts on each anchor.
4. Check load cell plumb once more, and then tighten down nuts on anchors.
Installing Load Cells
1. Unpack the load cells and mark each calibration certificate with the load cell
location/position.
2. Starting at one end of the assembled platform, place hydraulic jacks at the
corners so the section can be lifted off the locating tool. (Two (2) hydraulic jacks
may be required).
3. Lift the platform so the load cell locating tool can be removed from the upper and
lower bearing cups. Once removed, fill both cups with grease.
4. The bottom of the cell has two flat sides which must be aligned with the flat sides
of the lower cup. Carefully lower the scale (hydraulic jacks) while seating the
bottom of the cell into the lower cup. Check the scale’s level and height,
particularly at the approaches. Use the load cell shims provided to adjust load
cell cups for correct height and to ensure that all cells share an equal amount of
the load. Center section cells will have up to twice the deadload of end section cells.
~Caution~
Wear appropriate eye protection to reduce the potential for eye injury as grease may
be sprayed from the receiver cups when installing the load cells.
5. Once satisfied with height and level, tighten the module-to-module bolts.
• The bolts must be torqued to 500 ft lbs.
