FIST GRIP CLIPS
RECOMMENDED METHOD OF APPLYING FIST GRIP CLIPS
1. Turn back the specified amount of rope from the thimble. Apply the first clip one base
width from the dead end of the wire rope. Tighten nuts evenly to recommended torque.
2. Apply the next clip as near the loop as possible. Turn on nuts firmly but do not tighten.
3. Space additional clips if required equally between the first two. Turn on nutstake up
rope slack-tighten all nuts evenly on all clips to recommended torque.
4. NOTICE! Apply the initial load and retighten nuts to the recommended torque. Rope
will stretch and shrink in diameter when loads are applied. Inspect periodically and
retighten.
A termination made in accordance with the above instructions, and using the number of
clips shown has an approximate 80% efficiency rating. This rating is based upon the
catalog breaking strength of wire rope. If a pulley is used in place of a thimble for turning
back the rope, add one additional clip.
The number of clips shown is based upon using right regular or lang lay wire rope, 6 x 19
class or 6 x 37 class, fibre core or IWRC, IPS or EIPS. If Seale construction or similarly
large outer wire type construction in the 6 x 19 class is to be used for sizes 1 inch and
larger, add one additional clip.
The number of clips shown also applies to right regular lay wire rope, 8x 19 class, fibre
core, IPS, sizes 11/2 inch and smaller; and right regular lay wire rope, 18 x 7 class, fibre
core, IPS or EIPS, sizes 1 1/2 and smaller.
For other classes of wire rope not mentioned above, it may be necessary to add additional
clips to the number shown.
If a greater number of clips are used than shown in the table, the amount of rope turnback
should be increased proportionately. AVORED BASED ON USE OF FIST GRIP CLIPS ON
NEW WIRE ROPE.
Failure to make a termination in accordance with aforementioned instructions, or
failure to periodically check and retighten to the recommended torque, will cause
a reduction in efficiency rating.
