Eye Splice and Wire Rope Sling Creation
You create an eye splice when you need a loop at the end of a wire rope. This loop helps you attach hooks, shackles, or other lifting hardware. You use a full tuck to weave the strands back into the rope, forming a strong and reliable eye. You often use eye splices to make wire rope slings for lifting heavy loads.
Industry standards require you to use the correct number of clips for each splice type. The table below shows the requirements:
Type of Splice | Number of Clips Required |
|---|---|
Turnback Eye Splice | Must use the number of clips specified by the manufacturer or as per Table 15-2. |
Lap Splice | Must use double the number of clips specified for a turnback eye termination or Table 15-2. |
Powerful Machinery’s Steel Wire Rope gives you the strength and stability needed for eye splices. You can trust the rope to maintain its shape and resist twisting, which is important for safe lifting operations.
