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 minimum breaking force
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
classification or 6 x 36 classification, fiber core or IWRC; IPS, EIP
or EEIP.
If
Seale construction or similar large outer wire type construction in the
6 x 19 classification is to be used for sizes 1 inch and larger, add one additional
clip.
The number
of
clips shown also applies to rotation resistant right regular lay
wire rope, 8 x 19 classification, and 19 x 7 classification,
IPS, EIP and EEIP
sizes 1-1/2 inch and smaller.
For other classifications
of
wire rope not mentioned above, it may be neces-
sary 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.

IMPORTANT:
Failure to make a termination in accordance with aforemen-
tioned instructions,
or
failure to periodically check and retighten to the recom-
mended torque, may cause a reduction
in efficiency rating.
