9.
X-Bracket to X-Brace and to Main Rails (Figure 3, Item 6). These welds join X-brace members and join X-
braces to main rails. Sound welds in these joints are necessary to ensure that frame, with load, will remain
square during handling and transport. A crack should be repaired before it reaches 1.0 inch (25.4 mm) in length.
Combined length of multiple cracks at any X-brace joint should not exceed 2.0 inches (50.8 mm).
10.
Rear Beam Outrigger Tubes to Main Rails (Figure 3, Item 7). These welds join rear beam outrigger tubes to
gusset plates, which join to main rails and to beam center segment. Sound welds in these joints are necessary
to ensure safe support of bridge bays during handling and transport as well as supporting loaded BAP when
resting on BAP rear feet. A crack should be repaired before it reaches 1.5 inches (38.1 mm) in length. Combined
length of multiple cracks at any one joint should not exceed 2.0 inches (50.8 mm).
11.
Rear Roller Axles to Beam End Plates (Figure 3, Item 8). These welds join rear roller axles to beam end plates.
Sound welds in these joints are necessary to ensure safe support of bridge bays during handling and transport.
A crack should be repaired before it reaches 1.0 inch (25.4 mm) in length. Combined length of multiple cracks
at either of the axle joints should not exceed 1.5 inches (38.1 mm).

Bail Bar to Plates (Figure 4, Item 1). These welds join bail bar to plates. Sound welds in these bar joints are
necessary to ensure safe handling of bridge bays and loaded BAP. A crack should be repaired before it reaches
1.0 inch (25.4 mm) in length. The combined length of multiple cracks at any joint should not exceed 1.5 inches
(38.1 mm).
