There are 12 portable deck ramps. They should
be numbered 1 through 12 from port to starboard.
The numbering should be large enough to facilitate
easy identification and placement in corresponding
positions on the flight deck.
The purpose of the deck ramps is to ensure that
the aircraft landing gear does not become entangled
with or damage the lower load straps during
approach and engagement of the barricade.
Deck ramps are normally installed by V-1
division personnel during barricade rig evolutions.
The multiple-release assemblies provide the
connection between the upper and lower load straps
of the barricade and the tensioning pendants of the
barricade stanchions. They serve to release the
webbing assembly during an aircraft engagement
(figs. 3-32 and 3-34.)
The multiple-release assembly consists of a
number of release straps attached to loops at the
ends of the load straps. They are then attached to
the tensioning pendants by preswagged snap hooks
or quick-release pin and chain assemblies. During
an emergency arrestment, the force of the aircraft
engaging the barricade breaks the multiple-release
straps, releasing the barricade from the tensioning
pendants (fig. 3-33), allowing it to fall over the
The energy of the engagement is then
transferred from the barricade through the purchase
cable to the arresting engine.
Barricade stanchions house the winches that
tension and support the barricades. They further
provide the structure on which the barricade is
raised or lowered.
Except for differences of location and position
of the actuating apparatus-deckedge, above or
below deck-port and starboard stanchions are
identical. The port stanchions with their actuating
apparatus are described in this chapter. Barricade
stanchions (fig. 3-35) are welded steel, tray-shaped
assemblies that consist essentially of a base (6) on
which is hinged the frame (12). Each barricade
frame contains the winches (10), sheaves, and
pendants (1) used to tension the upper barricade
webbing load strap.
Each barricade stanchion is provided with a slot,
at the top of the inboard side, through which passes
the upper tensioning pendant. The frame moves as
a hinge around the two stanchion shafts (8), the
barrel of the hinge being the base and the knuckles
of the hinge being the hubs of the stanchion frame.
The two shafts act as the pins of the hinge. The
actuating arm (5) is keyed and pinned on the outer
shaft and is pinned to a holder on the stanchion.
Rubber bumper pads (3) are bolted in the deck
recess to cushion the shock of lowering the
BARRICADE STANCHION WINCHES
One winch is mounted in each barricade
stanchion and is attached to the tensioning pendant
of the upper loading strap of the barricade.
The barricade stanchion winch (fig. 3-36) is a
worm-driven winch whose component parts include
1. Worm wheel
11. Winch base
14. Locking pawl
5. Bevel gear
15. Pawl handle
6. Ratchet lock
16. Winch cover
9. Drum handle
