DISASSEMBLY - DOUBLE STORY - 2E + 12 BAY (Restricted Site - Original Far Bank)
This paragraph provides only the additional or modified steps needed to disassemble the 2E + 12 bay MGB on the
original far bank, on a restricted site. The operator must be familiar with, or refer to, the General Drills (Chapter 4) and
Disassembly Double Story 2E + 12 bay - Normal Site - Original Far Bank (para. 6-3).
The original far bank becomes the new near bank, and the original near bank becomes the new far
bank. Also the bays of the bridge must be renumbered from the new far bank. Using a 2E + 12
Bay as an example, what was bay 12 is now bay 1, and what was bay 1 is now bay 12.
All reference to near or far bank from this point will be referring to the new near bank and the new
far bank. Move all launching nose components to the far bank, and all the roller beam
components to near bank. All pallets must be moved to near bank.
Perform steps b. (1) thru (3) and (5) thru (6) in paragraph 6-3. The rear roller beam is assembled and
positioned later at step (14).
Using landing roller pedestal, raise bridge off ground until jack is fully extended.
Vehicle is holding bridge and roller catches in front roller beam are locked.
Delaunch bridge to panel point 4 of the last bay of bridge 1 2p4 (over front roller beam).
