BAY RETRIEVAL (Contd)
Do not place fingers under transverse upper couplings
when opening them, or serious injury to personnel may
Use the roadway tool and crowbar to close the gap
between inner pontons when transverse upper
couplings cannot be opened otherwise.
ab. Open two transverse upper couplings (8) by lifting each lever and returning
it to its own receptacle block.
To prevent seizure and distortion, ensure lower lock-
drive jackscrew is backed-off one full rotation after
lower lock-drive pin is fully retracted.
ac. Using T-wrench, turn lower lock-drive to ensure jackscrew (15) moves freely
and lower lock-drive pin (14) is fully retracted.
ad. Using T-wrench or round end of crowbar, open two outer ponton locks (9) at
each end of both outer pontons. Visually check to see each lock/release
lever (10) is clear of catch plate (11).
ae. Move two foldlocks (13) to closed position (facing up) at each end of bay.
af. Move travel latch (12) to closed position (facing down) at each end of bay.
