steel wire rope end terminations supplier

As a rigger or end-user of wire rope, it’s important to understand the types of terminations, or treatments, that can be used at the ends of a length of wire rope. These terminations are usually made by forming an eye or attaching a fitting, and are designed to be a permanent end termination on the wire rope where it connects to the load.

Wire rope is an extremely versatile mechanical device that can be used to help support and move an object or load. In the lifting and rigging industries, wire rope is attached to a crane or hoist and fitted with swivels, shackles or hooks to attach to a load and move it in a controlled matter. It can also be used to lift and lower elevators, or as a means of support for suspension bridges or towers.

In this article, we’ll explain what some of the following terms mean and how the can be used to terminate the end of a wire rope cable:Wire rope sockets—spelter sockets, swaged sockets, and wedge sockets

When you understand the construction and specifications of the wire rope you need, as well as the right type of end termination you need, you’ll be able to select the best performing and longest-lasting wire rope for the job at hand.

There are essentially two techniques that can be used to create a termination on a length of wire rope or cable:You can form an eye, or loop, in the wire rope

Eyes, or loops, can be created at one end of a length of wire rope by using a mechanical splice with a swaged sleeve, a hand-tucked splice, or wire rope clips.

A swaged socket is applied to the end of a wire rope cable and is then forced into place using special dies and a hydraulic machine called a swager. When properly applied with the correct sized fitting, swaged sockets have an efficiency rating of 100% of the breaking strength of the rope.

A poured socket, commonly referred to as a spelter socket, attaches a termination fitting onto the end of a wire rope cable by pouring molten zinc or resin into a socket that then hardens and holds the fitting onto the end of the cable.

Due to the rigidity of this type of termination, the wires of the rope are subject to fatigue where the wires enter the socket, if the poured socket is subject to constant vibration.

Wedge sockets secure the rope to the end attachment by passing it around a grooved, wedge-shaped piece of steel and pulling it down under load into the bowl of the fixture.

Wedge sockets are popular because they can be installed in field and adjusted in field – providing 80% efficiency of rope breaking strength. Wedge sockets are popular in applications where the wire rope may be subjected to abuse and abrasion—particularly in construction and mining applications.

Wire rope clips can be used to form a load bearing eye at the end of a cable or wire rope, or to connect two cables together with a lap splice. Wire rope clips are popular because they can be installed in the field and provide 80% efficiency of the rope breaking strength.

However, the use of wire rope clips is heavily regulated by ASME B30.26 Rigging Hardware. When using wire rope clips, the end user must account for the following:When using U-bolt wire rope clips, the saddle shall be placed on the live end of the wire rope, with the U-bolt on the dead-end side—NEVER SADDLE A DEAD HORSE!

After installation, the connection shall be loaded to at least the expected working load. After unloading, the wire rope clips shall be re-tightened to the torque specifications of the manufacturer or a Qualified Person.

This type of wire rope clip is essentially a U-bolt, two nuts, and a metal base (saddle) that can be made from forged steel or cast iron. Careful consideration and attention must be given to the way U-bolt type wire rope clips are installed.

The base of the wire rope clip is made from forged steel. Forged clips are heated and hammered into the desired shape—resulting in a consistent grain structure in the steel. Forged wire rope clips are used for critical, heavy-duty, overhead loads such as winch lines, crane hoist lines, support lines, guy lines, towing lines, tie downs, scaffolds, etc.

Malleable wire rope clips are used for making eye termination assemblies only with right regular lay wire rope and only for light duty uses with small applied loads, such as hand rails, fencing, guard rails, etc. The base of the wire rope clips is made from malleable cast iron, which may fracture under heavy use and does not have the desirable metal properties of steel, or the beneficial grain structure that a forged base has.

Double saddle wire rope clips consist of two saddles, each with a leg, and two nuts—one used on the top and one on the bottom. Double saddle wire rope clips can be used in either direction, so they take the guesswork out during installation when applying to the live end and the dead end of a piece of wire rope.

An eye splice may be used to terminate the loose end of a wire rope when forming a loop. The strands of the end of a wire rope are unwound and then the wire is bent around, and the unwrapped strands are then weaved back into the wire rope to form an eye.

A Flemish eye splice is created when the wire rope is opened, and the strands are laid out into two parts. The two strands are looped in opposite directions and then laid back together—forming an eye, or loop, at one end of the wire rope cable. The strands are then rolled back around the rope body and a metal sleeve fitting is slipped over the splice and swaged using hydraulic machinery. This splicing method provides the most efficient use of rope capacity and is highly economical.

A hand tucked splice is formed when the shorter “dead” end is tucked into the longer “live” end of the wire rope—forming an eye. These types of splices allow for easy inspection of the wire rope wires and strands.

When the end of a rope is turned back and formed into an eye, a thimble is often used to keep the shape of the eye, prevent the rope from being crushed, and keep the rope from being bent at a diameter smaller than the rope manufacturer’s recommendations.

The table below will explain the efficiencies of the different types of wire rope end terminations for both independent wire rope core (IWRC) and fiber core (FC) wire rope configurations. Rope efficiency is described as the ratio of a wire rope’s actual breaking strength and the aggregate strength of all individual wires tested separately—usually expressed as a percentage.IWRCFC

*Spelter sockets in smaller rope sizes (usually less than 7/16”) may not always develop 100% efficiency and are not recommended by some rope manufacturers.

When you need to order a replacement wire rope, understanding the right type of end termination will help to make sure you get a direct replacement rope so you can get your project back on track. We hope this article gives you a better understanding of terms related to sockets, wire rope clips, and eye splices and that you understand what type of end termination may be best for your application.

For crane wire ropes many different types of sockets are used: open and closed spelter sockets, open and closed swage sockets, wedge sockets and Nemag rope pear sockets.

A wedge socket termination reduces the wire rope efficiency to 80%, but the wedge socket remains a popular choice because it is easy to install and can be attached after the wire rope is reeved.

The Nemag rope pear socket when paired with the Nemag quick release link forms an unbreakable connection between two ropes. Together, they enable quick and straightforward coupling and uncoupling of grabs on cranes. Made from high grade austenitic manganese steel, these Nemag fittings generally outlast the wire rope.

Our Spelter sockets and Nemag rope pear sockets are poured with Wirelock, the original cold socketing resin and the first socketing system to meet the performance criteria of DNV for offshore wire mooring rope, currently the DNV-OS-E304 standards. Wirelock produces a void free socket for 100% efficiency and safety, and is unparallel in dependability and fatigue performance.

Our sockets are made of high quality cast steel supplied in hot dipped galvanised finish and comply with EN10204 3.1/3.2, JIS F3432 or RR-S-550D, Type B standard.

Large structures and equipment needing stabilization and support require specially-fabricated wire rope products. These assemblies usually fit swaged or poured terminations to wire rope. Assemblies like these used on boom cranes are referred to as either pennant or boom lines. Similarly-made products are also frequently used in structures such as large awnings and support cables for bridges.

The proper application of these types of assemblies requires careful consideration of capacity, length, plane, and type of termination. The capacity of the socketed assembly will be determined by the diameter and grade of wire rope. Trinity Sling offers a wide variety of wire ropes suitable for socketed and threaded wire rope terminations. The length of a socketed or threaded wire rope assembly requires exacting measurements. These usually are ordered in pairs and require length matching. Due to the differences in stretch inherent in different batches of wire rope, it is not recommended that new socketed slings be matched to used assemblies. The lengths will be mismatched under load.

At Trinity Sling we have years of experience with the various types of socket terminations. The terminations most commonly come with one of three types of connections; open socket (female), closed socket (male), and threaded ends. An open socket looks like a fork with a pin that can be inserted to close and secure the end fitting to the opening of the fork. A closed socket has an eye. The eye of the closed socket is designed to accept the pin of the open socket so they can be linked together. Threaded wire rope end fittings can be made with any type of thread pitch or thread length required for the application.

With open and closed socket wire rope terminations the plane of the attachment to the wire rope is also important. The plane of the assembly is determined by the degree relative to each end to which the terminations are attached. Consult the diagram from the Wire Rope Sling User’s Manual for reference to same and opposite planes.

Whether a job requires poured sockets or swaged sockets, well-built assemblies will carry up to 98% of the rated break strength of the rope. Poured sockets are usually set with an epoxy covering the broomed wires inside the socket, while swaged end fittings are attached by forming the shank of the end fitting over the wire rope with a press. Poured socket wire rope end fittings feature flexibility of assembly.

With a properly-trained person and the right equipment, poured sockets can be made in the field. Field installation should not be used in critical or overhead lifting or supporting applications, however, as those applications cannot be proof tested in the field.

As for all products fabricated by Trinity Sling we use only the highest quality materials and industry-recommended manufacturing techniques for our end fittings. Trinity Sling’s high capacity test bed is available for proof loading and recertification of all type of pennant lines and socketed end fittings. Trinity Sling can also offer tagging and asset tracking of each assembly with the InfoChip tagging and tracking system.
