BAY RETRIEVAL (Contd)
All personnel must wear approved life jackets while on
the bay. Failure to comply may result in injury or death
Do not place fingers under transverse upper couplings
when opening them, or serious injury to personnel may
Use roadway tool and crowbar to close gap between
inner pontons when transverse upper couplings cannot
be opened otherwise.
v. Open two transverse upper couplings (2) by lifting each lever and returning
it to its own receptacle block.
Perform steps w through aa for retrieval of ramp bay, or
perform steps ab through af for retrieval of interior bay.
w. Secure both ramp plates (3) (WP 0010 00).
To prevent seizure and distortion, ensure lower lock-
drive jackscrew is backed-off one full rotation after
lower lock-drive pin is fully retracted.
x. Using T-wrench, turn lower lock-drive to ensure jackscrew (7) moves freely
and lower lock-drive pin (6) is fully retracted.
As viewed from rear of bay (approach ramp end),
disengage the right-hand ponton swivel hooks by
turning shafts counterclockwise and the left-hand side
y. Using T-wrench, disengage one swivel hook, at both ends of both inner
pontons, by turning shaft (1) until indicator is not visible.
z. Move two foldlocks (5) to closed position (facing up).
aa. Move travel latch (4) to closed position (facing down).
