Figure 4-10.Drum windings diagram for selecting the proper lay of rope.
Carefully study figure 4-10, which shows
drum-winding diagrams selecting the proper lay of
rope. When putting wire rope onto a drum, you
should have no trouble if you know the methods of
overwinding and underwinding shown in the
illustration. When wire rope is run off one reel onto
another, or onto a winch or drum, it should be run
from top to top or from bottom to bottom, as shown in
If a wire rope should forma loop, never try to pull
it out by putting strain on either part. As soon as a
loop is noticed, uncross the ends by pushing them
apart. (See steps 1 and 2 in figure 4-12.) This
reverses the process that started the loop. Now, turn
the bent portion over and place it on your knee or
some firm object and push downward until the loop
straightens out somewhat. (See step 3 in figure 4-12.)
Then, lay the bent portion on a flat surface and pound
it smooth with a wooden mallet. (See step 4 in
If a heavy strain has been put on a wire rope with
a kink in it, the rope can no longer be trusted. Replace
the wire rope altogether.
