What to Look for With Your Winch Cable in Need of Replacement
A winch cable has to withstand a lot of
force when being used for situations that involve recovery. Whether it be for vehicle
recovery, industrial lifting, or marine operations, the cable experiences
significant stress with every pull. This is why knowing whether it is time to
replace your cable and how to do so is a crucial aspect of winching safety and
efficiency. There are several warning signs indicating that the time has come
to change your winch line, as listed below -
Signs Indicating It Is Time to Replace Your Winch Cable
Broken Wires
It is very easy to spot broken cables with
a quick visual inspection. However, you have to remember about the potential
risk of getting cut while performing such examination.
The best way to perform visual inspection
is to wear gloves and gently run your fingers along the cable surface, trying
to feel if there are protruding wires. Even if you feel only one or two, it is
already clear that your cable needs replacing.
In case the number of broken wires reaches
five in one strand or ten wires within one rope lay length, it must be replaced
immediately.
Kinking
Another obvious indication that you need to
replace your winch line is kinking. While a normal bend in a cable might seem
harmless, kinks are another matter entirely. As soon as the cable gets kinked,
it loses a significant amount of strength and will not be able to carry the
required load.
Bird-Caging
This is another condition which is easily
visible during the visual check. When the cable gets separated into individual
wires and takes the shape of a bird cage, it definitely requires changing.
Kinks and bird-caging both are usually
caused by a sharp impact or incorrect spooling of the cable.
Corrosion
While rust itself is quite a common thing
for a winch line, severe corrosion and discoloration of the cable are another
story. The main concern regarding corrosion of a cable is that it is likely to
affect the metal deep inside, meaning that a cable will weaken considerably in
places unseen from outside.
Wear and Reduction of Diameter
As we have mentioned above, you should be
especially careful about those parts of the cable which experience high levels
of mechanical strain.
To see if it is time to get your winch
cable replaced, take measurements of its diameter at various locations and see
if it has decreased by more than 10% compared to the initial value.
Heat Damage
Even if the winch cable has experienced
excessive overheating without other visible damage, it still will be useless as
it will weaken significantly. Blue or brown discolouration always indicates
that the cable has overheated at some point and should not be used any longer.
Regular Inspection and Checking for Damage
It is important to establish an inspection
routine based on the intensity of the cable's use. In case you use a winch on a
recreational basis, you will need to examine the cable once at the beginning of
each season as well as after a hard recovery. Professionals will need to
perform this operation more often – perhaps even after each use.
Choosing a Suitable Replacement for Your Winch Cable
If your inspection showed that there is
something wrong with your winch cable and you need to replace it, you will have
to choose a proper replacement. Nowadays, 7x19 construction galvanized steel
cable remains one of the most popular types of winching cable, and for a
reason.
