3.
When three or more clips are required, space additional clips equally between first
two - take up rope slack - use torque wrench to tighten on each U-Bolt evenly, alternating
from one nut to the other until reaching recommended torque.
4. If a pulley (Sheave) is used, in place of a thimble add one
additional clip. Clip spacing should be as shown.
5. WIRE ROPE SPLICING PROCEDURES:
The preferred method of splicing two wire ropes together is to use interlocking
turnback eyes with himbles, using the recommended number of clips on each eye (See
Figure 5).

An alternate method is to use twice the number of clips as used for a turnback termination.
The rope ends are placed parallel to each other, overlapping by twice the turnback
amount shown in the application instructions. The minimum number of clips should
be installed on each dead end (See Figure 6). Spacing, installation torque, and
other instructions still apply.
6. IMPORTANT
Apply first load to test the assembly. This load should be of equal or greater weight
than loads expected in use. Next, check and use torque wrench to retighten to recommended
torque. In accordance with good rigging and maintenance practices, the wire rope
end termination should be inspected periodically for wear, abuse, and general adequacy.

If a pulley (sheave) is used for turning
back the wire rope, add one additional clip. |
|
If a greater number of clips are used than
shown in the table, the amount of turnback should be increased proportionately. |
|
*The tightening torque values shown are
based upon the threads being clean, dry, and free of lubrication. |

|
Efficiency ratings for wire rope end terminations are based upon the
catalog breaking strength of wire rope. The efficiency rating of a properly prepared
loop or thimble eye termination for clip sizes 1/8" through 7/8" is 80%,
and for sizes 1" through 3-1/2" is 90%.
The number of clips shown (see Table 1 ) is based upon using RRL or RLL wire rope,
6 x 19 or 6 x 37 Class, FC or IWRC; IPS or XIP, XXIP. If Seale construction or similar
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. If a pulley (sheave) is used for turning
back the wire rope, add one additional clip.
The number of clips shown also applies to rotation - resistant RRL wire rope, 8
x 19 Class, IPS, XIP, XXIP, sizes 1-1/2 inch and smaller; and to rotation-resistant
RRL wire rope, 19 x 7 Class, IPS, XIP, XXIP sizes 1-3/4 inch and smaller.
For other classes of wire rope not mentioned above, we recommend contacting Crosby
Engineering at the address or telephone number on the back cover to ensure the desired
efficiency rating.
For elevator, personnel hoist, and scaffold applications, refer to ANSI A17.1 and
ANSI A10.4. These standards do not recommend U-Bolt style wire rope clip terminations.
The style wire rope termination used for any application is the obligation of the
user.
For OSHA (Construction) applications, see OSHA 1926.251.
1.
Refer to Table 1 in following these instructions. Turn back specified amount of
rope from thimble or loop. Apply first clip one base width from dead end of rope.
Apply U-Bolt over dead end of wire rope live end rests in saddle (Never saddle
a dead horse!) Use torque wrench to tighten evenly, alternate from one nut to the
other until reaching the recommended torque.
2.
When two clips are required, apply the second clip as near the loop or thimble as
possible. Use torque wrench to tighten evenly, alternating until reaching the recommended
torque. When more than two clips are required, apply the second clip as near the
loop or thimble as possible, turn nuts on second clip firmly, but do not tighten.
Proceed to Step 3.
