is a Flemish eye formed at a rope end secured by means of a ferrule pressed on the main body of the rope and the tail ends of the strands from the Flemish eye.

is a termination to form an eye whereby the ropes firstly undergoes a limited form of hand splice which is then completed by mechanically swaging a steel ferrule over the ends of the rope. This method is the dominant splicing in North America.

is an eye termination completed solely by unlaying the rope and relaying to form an eye. No ferrule is used. It’s rarely seen on steel wire ropes in Europe and North America due to cost of production.

“Giant Pliers” or Sailor tongs is used to press the smaller ferrules. A hand tool may have more than one cavity. It is not to be used for safety critical applications.

is an eye termination containing a Thimble.

is the trade name used for the TALURIT range of hexagonal dies for use with Stainless Steel Terminals. It is also used for special swages with hexagonal shapes. Normally used for lower strength applications.

is a registered trademark of Talurit AB. It is applied to the TALURIT range of DIN 3093 Aluminium Turnback ferrules. ISO 8793 is an International Standard Organisation’s standard for FSET’s. It defines certain manufacturing parameters and type approval requirements.

Splice which used some form of Ferrule or End Stop, which is then swaged onto the rope. Both Turnback and Flemish Eye Splices are Mechanical Splices.

Factor derived from fill factor and used in the calculation to determine the nominal metallic cross-sectional area of a rope. This may be expressed as C=f*ð/4

The product of the metallic cross-sectional area factor (C) and the square of the nominal rope diameter. This may be expressed as A=C*d²


is a machine used to compress ferrules onto a rope. The tooling (swaging dies) is changeable. May be hand operated or powered. Force is delivered to the swages via a hydraulic ram held in the Press Head. Defined by maximum ram force in tons or kN. Also called Swager.

is the part of the press, which consists of a cast or fabricated frame containing the hydraulic ram and die holder.

is a hardened steel plate in the Die Holder upon which the Dies/Angle Packings are placed. Used to prevent damage to the softer die holder.

is the valve, which allows the press hydraulic output pressure to vary (and thus the pressing tonnage).


is the average force applied when performing a proof test (the average force to which a product may be subjected before deformation occurs). Proof Load is usually twice the working load limit.

is a machine used to test wire rope slings and other rigging equipment by applying a pre-determined load. This load is normally twice the rated Safe Working Load of the sling or fitting. Proof Load machines are not suitable for destruction testing. Defined by force in tons or kN.

is a combined Proof Load/Destruction Test Machine. The capacity of the machine to proof load is far greater than its capacity to destruction test in terms of rope diameter.


The pressing cycle is completed by feeding the assembly between two opposed wheels, shaped as rotating dies. These are forming the outer diameter. Can only be used for terminals or sockets.



A strand with a perpendicular cross-section, which is approximately the shape pf a circle.

Single wire or strand used for making close-wound helical serving to retain the elements of a rope in their assembled position.

are dies/swages designed to press ferrules with a minimum of three bites, the dies being moved after the first and second bites. The dies have a chamfer at one end. It is used to increase the capacity of the press. For use only with untapered Aluminium and Copper Turn back splices. See relevant data sheet.

is a force that results from a rapid application of a load (such as impacting or jerking) or the rapid movement of a static load. Shock loads add significantly to the static load and should be avoided.

is the North American term for ferrule. Often referred to ferrule when concerning steel ferrules for Flemish Eye Splicing. See FERRULE.

is a Talurit range of steel turn back ferrules. A limited range of sizes is available.

Sockets are designed to fit one part of wire rope and may be applied with socketing media, wedges, or by swaging.

is an Eye termination not containing a Thimble.

is a range of ferrules conforming to BS 528, ISO 8793, DIN 3093 and EN 13411.

A round strand (CWS) or independent stranded rope (CWR) construction for stranded rope.

An element of rope normally consisting of an assembly of wire of appropriate shape and dimensions laid helically in the same direction in one or more layers around a centre.

is a North American term for press. See PRESS.

is a limited range of thin wall figure 8 shaped ferrules used with synthetic ropes. It is not for use in safety critical applications.

is a trademark owned by Talurit AB in more than 70 countries. TAPERED DIES is a die with a parallel porting and tapered portion at one end only.

A level of requirement of tensile strength of a wire and its corresponding range. It is designated be the value according to the lower limit of tensile strength and is used when specifying wire and when determining the calculated minimum breaking force or calculated minimum aggregate breaking force of a rope.

is an eye formed at a rope end secured by means of a ferrule pressed onto the main body of the rope and the tail end.

is a Mechanical Splice whereby the rope is passed through the ferrule and then looped back on itself and back through the ferrule. The ferrule is then swaged onto the rope forming a FSET.

is the average load or force at which the product fails and no longer supports the load.

is a tool used to clamp directly onto a wire rope and hold it in a Test Machine.

in the European market a new standard has been built up to classify steel wire ropes. See EN 12385.
