The second step is to keep a tight
cable during hoist operations. Too
much slack is what causes the cable to
kink, tangle, break, and jump track on
the hoist.
When
you set a
pod on the
ground,
stop the
hoist as
soon as
the pod
hits the
ground.
f you let the MLRS hoist cable
foul up, you’ve really fouled up. Let-
ting the cable kink and jerk can ruin
the cable and maybe even the hoist
itself. What a mess!
The first step in keeping the cable
out of trouble is to keep it clean—but
not lubed. Lubricants attract sand,
which cuts and weakens the cable. As
part of your weekly PMCS, clean the
cable with a rag
and isopropyl
alcohol. The
alcohol not only
gets rid of dirt, but
also any rocket
residue, which is
fertile ground
for corrosion.

Clean cables with
rag and alcohol
Be careful stowing the hoist, too. If
the hook assembly swings back and
forth, it bangs against the hoist car-
riage and the hooks are bent and the
pulley jams. Stop the hoist when the
hooks reach just below the hoist car-
riage and wait for the hooks to stop
swinging before stowing the hoist.
Don’t stow a swinging hook assembly
A little slack
in the cables
can usually be
cured by pulling
straight back on
the center cable
while the hook
assembly is down.
If you suspect the
cable has jumped
the drum track,
take the cover off
the hoist and look.
You can often get the cable back on
track by using the
