there are clips. Pay particular attention to the wire at the
clip farthest from the eye, as vibration and whipping are
heaviest here and fatigue breaks are likely to occur.
To obtain maximum strength in the temporary eye
splice, use the correct size and number of wire clips.
The size is stamped on the saddle between the two
holes. A rule of thumb for determining the number of
clips required for various sizes of wire rope is to
multiply the diameter of the wire rope by 3 and add 1.
Stated as a formula, this means
3D + 1 = number of clips.
For example, if the wire rope has a diameter of 1
inch, determine the number of clips as follows:
(3 x 1) + 1 = 4 clips
In case the answer contains a fraction, then use the
next largest whole number. For example, suppose you
want to find the number of clips for a wire rope 1/2 inch
in diameter. Using the formula, the answer would be 2
1/2 clips. You simply use the next whole number to get
the correct answer.
You should space the clips properly to provide a
good hold on the wire rope. You can determine the
correct distance between the clips by multiplying 6
times the diameter of the wire rope. Where D is equal to
