if the cable gets
lots
of use,
give it a coat of
OE-HDO 30 engine oil.
Stay away from
used
oil.
it contains acid that can
weaken the rope strands.
The cable
doesn’t
need oil
in dry, dusty areas, though.
in fact, oil just collects
more dust and dirt.
if the
wire rope
isn’t
used a lot,
or if
conditions
are damp
or salty,
give
extra
protection
with a
coat of
MIL-G-18458
wire rope
grease.

Cleaning
Inspecting
Lubing
Here’s what to do after a
muddy
or
dirty
operation…
While you’re cleaning, look for
kinks, bends, caging and other
damage. Broken wires can KO
the cable, too.
See your vehicle’s TM for
inspection details. FM 5-125,
Rigging Techniques, Procedures
and Applications,
and TB 43-
0142,
Safety Inspection and
Testing of Lifting Devices,
have
more good info.
Replace
the
cable if necessary.
A damaged cable should be
destroyed
to keep it from being
reused. Get your welder to cut the cable into small sections.
Bird-
caging
Don’t
Leave
Wire rope
stranded!
Exposed to
rain, snow, wind
and heat… it’s
a
hard life
for
us wire ropes
who are used
on cranes,
winches and
construction
equipment.
These
conditions
weaken
us
until we’re
no longer
useable
or safe!
PM will keep your
wire rope healthy,
but first you’ll
need to put on
some
leather
gloves
to protect
your hands from
broken strands.
Play out the wire rope and
stretch it out straight on a
clean surface, like a paved
motor pool.
Use a
wire brush,
like the one from
the standard
automotive tool
set (SATS), to
remove old
lube, dirt and
corrosion.
Clean the
entire
cable.
Grit and
corrosion get
buried among the
cable strands.
Lube the
wire rope
according
to the
lubrication
instructions
for your
equipment.
There are
some
other
things you
can do to
keep the
rope
mission-
ready.
I’ll
clean
ofF the
dirt…
…and I’ll
lube with some
frEsh Oil!
