RAMP BAY (FOLDED)
RAMP BAY CONTROLS AND INDICATORS
FOLDLOCKS — There are two foldlocks on the IRB-R, each located on the
inner ponton at the connecting end of the bay. It consists of a spring loaded
lever that is manually operated; before launch both foldlocks are opened to
allow the outer pontons to unfold as the bay is released into the water, and
prior to retrieval, both foldlocks are placed in the closed position so they will
automatically engage with the outer pontons as the bay is folded.
FRONT AND REAR LIFTING LUGS —
There are two different lifting lugs
on the IRB-R inner pontons. During launch and retrieval the bay is lifted from
the front lifting lug with one cable by the transporter. The rear lifting lug is
used when bay is lifted with two cables. Both contain an eyebolt which holds
the inner pontons together. Lifting from the front lifting lug is necessary to
achieve proper folding of the IRB-R and to load the bay on the transporter.
TRAVEL LATCH —
There is one travel latch on the IRB-R, located on the
inner pontons at the connecting end of the bay. It consists of a spring loaded
lever on the right inner ponton and a locating receptacle on the left inner
ponton. The travel latch is manually opened prior to conducting a free launch,
and opened using a lanyard pin (refer to Item 7, WP 0070 00) and rope after
conducting a controlled launch, high-bank launch, or deployment by
helicopter. Prior to retrieval, the travel latch is placed in the closed position
where it will automatically engage and latch the inner pontons when folded.
During pick-up and transport, the travel latch prevents the IRB-R from
unfolding.
