2-L: Assembling Weighbridge Sections
1: Identify each main beam pair per the certified prints, and select the appropriate end sec-
tion beams as the first to begin assembling. Place one main beam onto blocking, ensuring it
is supported and stable. Place the second main beam onto blocking, in parallel with the first
main beam, and close enough together to enable the middle crossmembers to be placed into
position

temporarily by laying them down onto the bottom flanges of the main beams and in-between
them. Note the correct orientation of these crossmembers as indicated by the certified prints.
Place the outriggers near their intended installation location, and the mounting hardware.

2: Starting at one end of the section, install the first crossmember into position, along with
both outriggers, leaving the bolts loose. Install the next crossmember, with its outriggers, and
proceed in order to the other end of the section. A chain come-along (with suitable capacity)
at the opposite end of the main beams can be used to slowly draw the main I-beams together
as the crossmembers and outriggers are being installed. When all crossmembers and outrig-
gers have been installed in this manner, tighten all bolts. Do not tighten to their final torque
value at this time.
3: Locate the Weighbridge Checking Bracket locations on the lower flanges of the main
beams, and per the Certified Prints. Raise that area higher and support it with blocking, the
bracket will require a minimum of fifteen (15) inches of clearance. Install and tighten the
weighbridge checking bracket.
