DISASSEMBLY - 2E + 22 BAY LINK REINFORCED
a.
Preparation for Disassembly
(1)
If pumps, hoses and water are available, the bridge, erection and link components should be washed
before loading them on to pallets.
(2)
If washing cannot be done, the components are loaded directly onto pallets.
b.
Disassembly
NOTE
Throughout bridge disassembly the NCOIC must monitor the height and level of the roller beams.
The height must be set to achieve an acceptable working height. Roller beams must be level so
that components connect/disconnect properly.
(1)
Remove bridge classification signs, bridge guide markers and curbs (reverse of para. 4-26). Retain six
curbs on the near bank end of bridge as part of counterweight [see step (4)].
(2)
Remove far bank ramp units, removing center ramp first (reverse of para. 4-24).
