INSPECT YOUR LUG-ALL DAILY FOR THESE
DANGEROUS CABLE CONDITIONS
Pictured here are examples of more obvious types of cable damage. These examples
are intended to illustrate severely damaged cables. Cables exhibiting damage of
this sort to any degree should be replaced immediately.
Drum Crushing and Spiraling
The badly deteriorated condition of this
cable clearly indicates that it is unsafe for
operation. Cable damage of this type is
usually caused by hoist abuse and by
repeatedly overloading the hoist beyond
its rated capacity. A hoist with this cable
condition should not be used under any
circumstances, and the cable must be
replaced before the hoist can be safely
operated.
Cut Cable
The condition of this cable indicates that
it has been cut by a sharp object. This is
apparent to the eye because several of
the strands appear to be of equal length.
It goes without saying that this cable must
be replaced before the hoist can be safely
operated.
Broken Wires
The frayed condition of this cable
indicates broken wires and an unsafe
condition. Cable deficiencies of this type
are usually caused by abrasion. This can
easily happen in a hoist operation if the
operator allows the cable to come in
contact with any other surface. This cable
is considerably weakened and must be
replaced before the hoist can be safely
operated.
Kinks
Kinks can result from improper uncoiling
and unspooling, or they can be formed in
hoist operation. Cable loops can occur in
a slack line, or in a line under tension. If a
loop occurs, it should be removed
immediately. Otherwise the loop may be
pulled through when tension is applied
to the line and form a permanently
deforming kink. Kinks in a cable are
always dangerous as they create unequal
tension in the rope and in the strands. A
cable with kinks must be replaced before
the hoist can be safely operated.
