core, within which is contained a paper or plastic tape
strip bearing the name of the wire rope manufacturer.
The function of the oiled hemp center is to provide a
"cushion" for each strand and also to supply lubrication
when the cable is under tension. The deck pendant
cable ends are equipped with swaged-type terminals.
These terminals are pinned to the clevis and socket
assembly at the purchase cable coupling for quick
detachment during replacement.
To remove a pendant, it is necessary to put slack in
the cable. If the pendant has been retrieved and must be
replaced, reduce the accumulator pressure to 200 psi
and pull the pendant out a few feet, using a deck tractor.
Hold the retracting valve open while the tractor is
pulling, then block the valve in the closed position to
prevent retraction. It may be necessary to clamp a block
on the purchase cable to prevent its slipping back due to
its own weight. If a pendant is badly damaged during an
arrestment and must be replaced immediately, either do
NOT retract the pendant or retract the pendant only
partially so that slack is left in the cable system.
Refer to figure 3-32, and perform the following
task to replace a deck pendant. Screw the lockscrew
into the clevis end socket, remove the anchor nut and
pull out the clevis pin. Secure the eye end of the
terminal of the new deck pendant to the clevis end
socket of the purchase cable socket assembly by means
of the clevis pin, anchor nut, and the lockscrew.
Recharge the accumulator and retract the engine.
Deck pendants are provided as assemblies—not
made up on board ship. Suitable handling facilities
should be available. Spare pendants should be
conveniently stowed, ready for quick rigging, since
replacement of a deck pendant is sometimes an
emergency procedure that must be performed quickly.
The replacement operation can best be performed
by four separate crews. One crew is needed to pull out
the pendant, one at each of the two couplings, and one
to bring the new pendant on deck and roll it out and in
position.
