PENDANT AND ANCHOR INSTALLATION
The pendant and anchor installation (fig. 3-40) is
the means by which the barricade webbing is
suspended and tensioned to maintain its 20-foot
midspan height above the flight deck. Components
comprising the pendant and anchor installation are:
four wire rope tensioning pendants, two stanchion
mounted winches. A deck mounted winch assembly,
and an anchor assembly.
Stanchion mounted 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 deck winch, through the tensioning pendants
provide a means of tensioning the starboard side lower
loading strap of the barricade webbing (see fig. 3-40).
The anchor assembly, through the tensioning
pendants provides a means of tensioning the port side
lower loading strap of the barricade webbing (see fig.
Tensioning pendants provide the link between the
winches, anchor and loading straps to keep the straps in
the correct position when a barricade is rigged (see fig.
STANCHION HYDRAULIC CYLINDER
The hydraulic cylinder (fig. 3-41) raises and lowers
the barricade stanchion when hydraulic fluid under
pressure is introduced into the cylinder on either the
raising side of the piston or the lowering side of the
piston. A front cap (3) and a rear cap (4) are each
attached to the cylinder ends by bolts and sealed by an
O-ring (13) and backup rings. Contained in the cylinder
(2) are a piston (1), a piston rod (5), and two plungers
(6), one on each side of the piston. The piston and
plungers are held in position on the rod by a castellated
nut and secured by a cotter pin. The piston and piston
rod are sealed by an O-ring (13) and backup rings. The
piston is fitted with two packing followers, two sets of
V-ring packings (12), four rings each, and two piston
