INTERIOR BAY CONTROLS AND INDICATORS
FOLDLOCKS — There are four foldlocks on the IRB-I, each located on the
inner ponton at both ends of the bay. The foldlock consists of a spring loaded
lever that is manually operated; prior to launch all foldlocks are opened to
allow the outer pontons to unfold as the bay is released into the water, and
prior to retrieval, all foldlocks are placed in the closed position so they will
automatically engage with the outer pontons as the bay is folded.
LIFTING LUG — There are two identical lifting lugs on the IRB-I inner
pontons. During launch and retrieval the bay is lifted by the transporter from
the lifting lug at either end. Both contain an eyebolt which holds the inner
pontons together. Lifting from the lifting lug is necessary to achieve proper
folding of the IRB-I, and to load the bay on the transporter.
TRAVEL LATCH — There are two travel latches on the IRB-I, each located
on the inner pontons at both ends of the bay. The travel latch consists of a
spring loaded lever that is manually operated, and a locating receptacle. Both
travel latches are opened prior to conducting a free launch. Only one travel
latch is opened prior to conducting a controlled launch, high-bank launch, or
deployment by helicopter, after which the 2nd travel latch is opened using a
lanyard pin (refer to Item 7, WP 0070 00) and rope. Prior to retrieval, both
travel latches are placed in the closed position and automatically engage and
latch the inner pontons when folded. During pick-up and transport, the travel
latches prevent the IRB-I from unfolding.
