BAP GENERAL WELDING MAINTENANCE (continued).
(4)
Front Lock Outrigger Tubes to Main Rails. These welds join front lock outrigger tubes to main rails.
Sound welds in these joints are necessary to ensure safe support of the loaded BAP when resting on
front feet. A crack should be repaired before it reaches 1.5 inches (38.1 mm) in length. The combined
length of multiple cracks at either front outrigger tube joint to main rail should not exceed 2.0 inches
(50.8 mm).
(5)
Front Roller Outrigger Tubes to Both Main Rails. These welds join front roller outrigger tubes to both
front and rear main rail segments. 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 1.5 inches (38.1
mm) in length. The combined length of multiple cracks at any one of the four tube joints (two for each
outrigger) to main rails should not exceed 2.0 inches (50.8 mm).
(6)
Front Main Rails to Rear Main Rails. These welds join front end of rear main rails and front main rails
via gusset plates. Sound welds in these joints are necessary to ensure safe support of the loaded BAP
during handling and transport. A crack should be repaired before it reaches 1.0 inch (25.4 mm) in
length. The combined length of multiple cracks at any of the rail joints should not exceed 2.0 inches
(50.8 mm).
(7)
Rear Holding Locks (DIN Locks). These locks secure the BAP to the Transporter, preventing it from
moving forward or up. These welds join the locks to the main rails. Sound welds in these joints are
necessary to ensure safe transport of the loaded BAP on the CBT or on a PLS trailer. A crack should be
repaired before it reaches 1.0 inch (25.4 mm) in length. The combined length of multiple cracks at
either of the lock joints should not exceed 2.0 inches (50.8 mm).
