UNFOLDING MECHANISM A system of cables, levers, and torsion bars
located at the front of the IRB-R, that automatically control the unfolding of
the inner and outer pontons once the bay is launched. During retrieval this
mechanism works in reverse by pulling the pontons up into the folded
position simultaneously, as the entire bay is lifted from the water via the
transporter.
RAISING MECHANISM The pump, cylinder, and yoke assembly,
contained on each of the two inner pontons, is used for raising and lowering
the ramp bay.
