DISASSEMBLY 2E + 22 BAY - W/O LINK REINFORCEMENT
a.
Preparation for Disassembly
(1)
If pumps, hoses and water are available, the bridge and erection components should be washed before
loading them on pallets.
(2)
If washing cannot be done, the components are loaded directly onto the proper pallet.
b.
Disassembly
NOTE
Throughout bridge disassembly the NCOIC must monitor the height and level of roller beams. The
height must be set to achieve an acceptable working height. Roller beams must be level so that
components connect/disconnect properly.

curbs on the near bank end of bridge as part of counterweight [see step (3)].

Leave both bays of near end of bridge fully decked (eight deck units).
(c)
Transfer remaining twelve deck units (this makes a total of twenty) and six curbs to complete the
counterweight on near bank end of bridge.
