3.0 Level and Align Frame, and Bolt Tightly
The following sections cover the steps in aligning and leveling the SR truck scale deck.
3.1 Align and Square Deck
Align the siderails with a string line and square the entire frame by measuring diagonals with a 100' tape. As the
siderails may not be perfectly vertical, measuring diagonals across the top flanges of the siderails may not reflect
the true squareness of the deck. The most accurate measurement will be diagonally from the center web of the
siderails at the level of the deck top.
If adjustments are necessary, a fork lift or crane can be used to nudge the frame into alignment.
3.2 Level Frame
If the concrete foundation pad has been sloped for water drainage, add the appropriate amount to the 8" setting
blocks on the low side to level the frame. Begin leveling the frame at one end of a section at the approach. With
hydraulic jacks, raise the ends of the siderails until the end #5 cross beam is at the same level as the approach.
Insert metal shims (large washers work well) on the setting blocks to maintain this level.
Move down the scale toward the other end, jacking and shimming until the entire deck is level in both directions.
When the entire deck frame is level, torque down all cross beam bolts to 260 ft. lb.
