How to measure (or caliper) a wire rope correctly. Since the "true" diameter (1) lies within
the circumscribed circle, always measure the larger dimension (2).
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, produce imbalance in the rope and may result in open or
closed kinks (Fig. 12). Once a rope is kinked, the damage is permanent. To correct this
condition, the kinks must be cut out, and the shortened pieces use for some other purpose.
