Assemble the Remaining Modules One at a Time
1. Set the second beams (both J-Box and Plain sides).
a. The end of the beams without an upper receiver plate should rest on the
receiver plate protruding from the base girder. Center the girder on the
load cell centerline and set on shoring timbers.
b. Align the hole in the flange of the interior beam with the hole in the receiver
plate on the base girder. Loosely bolt this connection, but do not fully
tighten.
c. At the joint where the two beams meet, install the threaded rod through the
center hole in the beam stiffeners, and through the 3/4" spacer pipe, which
fits between the stiffeners. Loosely install two nuts and one washer on
each end of the connection rod. Do not fully tighten.
2. Install the cross members as directed above.
3. Repeat these steps for each subsequent module until the final right hand end
modules is assembled.
Completing the Scale Assembly before Pour
1. Once all modules are assembled, check the square of the scale and adjust as
necessary to bring the scale into square.
2. Tighten all cross member bolts one-half turn past snug (min 350-425 ft-lbs).
3. Tighten all connection bolts that bolt through the flanges and load cell upper
receiver plates.
4. Tighten the bolts on all girder connection bolts (through the stiffeners) and ensure
that the jam nuts are secured.
5. Check scale square again.
6. Install locating tools and base plates at all load cell locations.
7. Ensure that there is an equal gap at each approach. If necessary, use the end
check bolts to adjust this gap.
8. If not already installed, install the side check brackets and lateral check bolts.
9. Tighten the longitudinal and lateral bumper checking bolts so that there is no gap.
They will hold the scale in place during the pour.
10. Use tape to “mask off” top flange of cross members to create a well-defined
concrete-to-flange interface.
