Assemble Frame Siderails and Cross Beams 5
2.0 Assemble Frame Siderails and Cross Beams
Whichever assembly sequence you chose, observe the following details.
• Use 8" high setting blocks so the deck frame will nearly match the level of the approaches.
• Don’t torque down cross beam assembly bolts tightly until the module is aligned and squared.
• Use a taut string line to align side rails.
• Measure diagonals with a 100' tape to assure frame is square within 1/4".
• Refer to the blueprints furnished with the scale for all component numbering sequences.
2.1 Connecting Siderails into Multi-Module Sections
A load cell mount sits directly under each multi-module joint splice and bears on both
siderail beams. The mount requires a flat surface at the joint to bolt to. Because of
material variances from the mill, the two beams may not be exactly the same height.
Always align the bottom of the beams when bolting together to create a flat surface for
the mounts top plate. Let any extra height protrude at the top of the siderail joint.
The six bolts connecting the two side rails must be torqued to 640 ft/lb. This cannot be
done with an impact wrench—a large torque wrench with extension handle will be
required.
2.2 Siderail Beam Identification and Positioning
The following sections outline the positioning and numbering of the SR truck scale siderail beams.
2.2.1 Siderail Positioning
Set all side rails with the cut-outs for the load cell mount down and the uncut
flange up. The headed anchor rods (Nelson studs) that will be encased in the
concrete deck face inward.
Gusset plates at the ends of single side rails which form an independent section
are solid.
Gusset plates at the end of side rails which bolt together to form a longer section
have three holes in each plate for these bolts as shown at left.
2.2.2 Siderail Numbering
All side rails are clearly marked with large numerals keyed to the final assembly drawing. Preview the drawing
before beginning to unload the truck. You will note that some side rails are interchangeable, while others are not
and must be placed exactly as the assembly drawing shows.
The truck will be loaded such that you can unload the side rails in order and set them directly into position on the
foundation without double handling. See the truck loading diagram for your scale model included with this manual.
2.3 Cross Beam Identification and Positioning
The following sections outline the positioning and numbering of the SR truck scale cross beams.
2.3.1 Cross Beam Positioning
Set all cross beams with the flush end of the drain tube up. The 3/8" threaded studs that attach the sheet metal
support bars should be near the bottom of the cross beam web.
