What is spliced wire rope slings and Why Do We Use Them?

Hand spliced wire rope slings, also known as hidden tuck slings, are made by constructing an eye and then tucking the tails of wire rope back into the body of the sling. This splicing technique creates a stable eye. This can be particularly useful when there are concerns regarding the possibility of the pressed sleeve of a standard wire rope sling getting caught or snagged during your lift. This is especially realized when using hand-spliced wire rope slings in a choker hitch configuration. Hand spliced wire rope slings make excellent chokers.

Hand spliced wire rope slings are considered to be the original technique to splice wire rope slings. Hand-spliced slings have a slightly less rated capacity than a Flemish Eye Sling and can be manufactured to your desired length +/- the diameter of the wire rope.

When it comes to lifting, hoisting, or securing heavy loads, wire rope delivers unmatched strength and reliability. However, you must splice it correctly using the right method for the job. This guide to various wire rope splicing techniques will help you understand the most effective ways to create secure terminations that meet high-load demands.

What Is Wire Rope Splicing?

Wire rope splicing involves forming a permanent connection at the end of a wire rope or joining two ropes together. These splices create loops, eyes, or terminations without the need for knots or welding. Compared to mechanical fittings involving clamps or clips, splicing often provides stronger and more reliable results.

Wire rope splices are critical in load-bearing applications such as crane rigging, winching, and overhead lifting. Professionals rely on these techniques to reduce slippage, maintain structural integrity, and meet safety standards.

Common Wire Rope Splicing Techniques

Professionals rely on several splicing methods to create strong terminations for wire rope used in demanding applications.

Flemish Eye Splice

The Flemish eye splice is one of the most widely used splicing methods in heavy-duty rigging. Technicians unravel the rope strands, loop them back into the rope body in a figure-eight pattern, and secure the splice with a steel sleeve or swage. The result is a solid eye at the end of the rope that holds under extreme tension—perfect for cranes, slings, and shackles.

Hand-Tucked Splice

This is the traditional method of splicing wire rope by manually weaving the wire strands back into the rope. While it takes more time and skill, it’s still used in specific applications, especially when a mechanical press isn’t available. Hand-tucked splices are common in logging chokers and custom rigging setups.

Swaged Splice (Mechanical Splice)

Swaging uses a hydraulic press to crimp a metal sleeve around the rope, holding the splice firmly in place. This method is precise, consistent, and widely used in industrial applications. Suppliers offer swaged terminations for wire rope slings, hoists, and lifting assemblies because they ensure maximum efficiency and safety.

Socketing

Socketing involves inserting the rope end into a conical socket and sealing it with molten zinc or resin. This creates one of the strongest possible terminations for wire rope. Socketed ends are ideal for permanent, high-load applications such as bridges, elevators, and tower cranes.

Why Proper Splicing Matters

Using the right splicing technique prevents equipment failure, reduces downtime, and ensures OSHA compliance. Poor splicing can lead to slippage or rope fatigue, increasing the risk of serious accidents. When done right, a quality splice extends the life of your rigging gear and supports the demands of your operation.
