DROP FORGED WIRE ROPE CLIPS - APPLICATION INSTRUCTIONS

WARNING!
Failure to read, understand, and follow these instructions may cause death or serious injury. Read and understand these instructions before using clips. Match the same size clip to the same size wire rope. Prepare wire rope end termination only as instructed. Do not use with plastic coated wire rope. Apply first load to test the assembly. This load should be of equal or greater weight than loads expected in use. Next, check and retighten nuts to recommended torque (See Table 1). For OSHA (Construction) applications, see OSHA 1926.251.

Efficiency ratings for wire rope and 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" 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 rotationresistant RRL wire rope, 8 x 19 Class, IPS, XIP, XXIP sizes 1-1/2" and smaller; and to rotation-resistant RRL wire rope, 19 x 7 Class, IPS, XIP, XXIP sizes 1-3/4" and smaller. 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.

Wire Rope Splicing Procedures: The preferred method of splicing two wire ropes together is to use inter-locking turnback eyes with thimbles, using the recommended number of clips on each eye (See figure 5). An alternate method is to use twice the number of clips 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.

1. Refer to Table 1 in following these instructions. Turn back specified amount of rope from thimble or loop. Apply U-Bolt over dead end of wire – live end rests in saddle (Never saddle a dead horse!). Tighten nuts 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. Tighten nuts 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 in second clip firmly, but do not tighten. Proceed to step 3.

3. When three or more clips are required, space additional clips equally between first two – take up rope slack – tighten nuts 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.

If a pulley (sheave) is used for turning back the wire rope, add one additional clip. See figure 4. If a greater number of clips are used in the table, the amount of turnback should be increased proportionately. The tightening values shown are based upon the threads being clean, dry, and free of lubrication.
