UNREELING AND UNCOILING
Wire rope is shipped in cut lengths, either in coils or on reels. Great care
should be taken when the rope is removed from the shipping package since it can
be permanently damaged by improper unreeling
or
uncoiling. Looping the rope
over the head
of
the reel or pulling the rope off a coil while it is lying
on
the
ground, will create loops in the line. Pulling on a loop will, at the very least, pro-
duce imbalance in the rope and may result in open or closed kinks (Fig. 18).
Once a rope
is
kinked, the damage is not repairable. The kink must be cut out or
the rope is unfit for service.

closed kink will close
it.
