Wire Rope Clip (ITALY TYPE)

タイトルまたは説明

How to apply clips:

The correct way to attach U-bolts is shown at the right, the U-section is in contact with the rope's dead end.



Apply the first clip one base width from dead end of wire rope, the next clip as near the loop as possible. Space additional clips if required equally between the first two.



Apply the initial load and retighten nuts. Rope will stretch and shrink in diameter when loads are applied. Inspect periodically and retighten.



IMPORTANT: Failure to make a termination in accordance with the instructions, or failure to periodically check and retighten to the recommended torque, will cause a reduction in efficiency rating. Never use any wire rope clips to directly connect two straight lengths of wire rope.



Wire Rope Clip Safety Notice!



Under the approved Code of Practice for Load Lifting & Rigging,

slings assembled with wire rope clips are not to be used for lifting.

To comply with manufacturer's specifications the correct number of clips must be installed correctly and tightened to the correct torque using a torque wrench. The correct installation technique is shown below.

 

When fitting clips "Don't straddle a dead horse".

A visual inspection should be carried out prior to and during use.

 

Wire rope clips should be inspected before use to ensure that:

all markings are legible;

the wire rope clip is free from nicks, gouges and cracks;

a wire rope clip with the correct dimension has been selected;

never repair or reshape a wire rope clip by welding, heating or bending as this may affect the performance.

The wire rope clip should be fitted to the wire rope as shown in the diagrams below.

The bridge of the wire rope clip should always be placed on the load bearing part of the rope. The U-bolt of

the clip should be placed on the rope tail, also known as the "dead end" of the rope.

Turn back enough wire rope length so that the required minimum number of clips can be installed according to the instructions below.

The first clip must be placed one bridge width from the turned back rope tail or dead end of the rope,

according to figure 1. Tighten nuts to the specified torque.



The second clip must be placed immediately against the thimble but nevertheless in such a position that the

correct tightening of the clip does not damage the outer wires of the wire rope (figure 2). Tighten the nuts

firmly but not yet to the specified torque.

The following clips should be placed on the wire rope between the first and second clip in such a way that

they are separated by at least 1½ times the clip-width with a maximum of 3 times the clip-width according to figure 3.Apply light tension on the rope and tighten all nuts evenly, alternating until reaching the specified torque.

During assembly and before the rope is taken into service, the nuts must be tightened once again to the

prescribed torque. After the load is applied for the first time, the torque value must be checked again and

corrected if necessary. Periodically re-tightening of the nuts must be done at *0.**0 cycles (heavy usage),

*0.**0 e.g. every 3 months, 6 months, annually.

The torque values and the minimum number of clips to be applied, in relation to the rope size, are given in

the following tables.
