Wire rope
Wire rope is composed of as few as two solid, metal wires twisted into a helix that forms a composite rope, in a pattern known as laid rope. Larger diameter wire rope consists of multiple strands of such laid rope in a pattern known as cable laid. Manufactured using an industrial machine known as a strander, the wires are fed through a series of barrels and spun into their final composite orientatispiral strands offer high strength and stiffness for a given diameter and wire grade; spiral strands can provide a high degree of torque balance; wires tend to be of larger Stranded Rope an overview ScienceDirect Topics

Cross section shape optimization of wire strands
This paper introduces a shape optimization of wire strands subjected to tensile loads. The structural analysis relies on a recently developed reduced helical finite rope, assemblage of fibres, filaments, or wires compacted by twisting or braiding (plaiting) into a long, flexible line. Wire rope is often referred to as cable ( q.v. ). The basic Rope Climbing, Boating & Industrial Applications

called “stranding”. Wire rope varies: • By Diameter • The grade of steel utilized • The direction of stranding and closing • The finish on the wire (Bright, Galvanized, etc.) • The core material Each variation changes the performance characteristics of the wire rope. The first differentiation of wire rope is by diameter. TheStranded wire, also referred to as wire strand, is made by stranding together individual wire filaments into strands and wrapping them helically around a core to make rope. It is made of wire filaments, strands, and a core. Strands are multiple wires arranged helically and symmetrically with uniform pitch or lay.Stranded Wire and Wire Braids IQS Directory

Technical information PFEIFER
Rope in which the strands, prior to closing of the rope, are subject to a compacting process such as drawing, rolling or swaging. Fig. 21 and 22 shows the standard, fig. 23 and 24 the compacted strand. J Compacted (swaged) stranded rope (fig. 26) After stranding the rope usually gets additionally compacted by swaging or rolling.The 120-wire spiral strand cable was modelled as the second example. Cable specimens of 6 m in length were tested by the manufacturer Bridon International Ltd. The specimens were socketed at both ends in the tests. FE modelling of a 200 mm-long cable with the mesh in Fig. 3 was carried out, with the fixed-end boundary condition Full 3D finite element modelling of spiral strand cables

Wire
History Wire wrapped jewelry. In antiquity, jewelry often contains large amounts of wire in the form of chains and applied decoration that is accurately made and which must have been produced by some efficient, if not technically advanced, means. In some cases, strips cut from metal sheet were made into wire by pulling them through perforations in stone This machine can be delivered with row by row loading or individual loading. Planetary stranding machines with backtwist for the production of steel ropes or for armouring of cables. The machines are equipped with backtwist and can operate with 0% and 100% or variable backtwist. Closing machines such as:Stranding Machines to make cable and rope STOLBERGER

What Is Wire Rope? Understanding the Specifications and Construction
Wire rope is a preferred lifting device for many reasons. Its unique design consists of multiple steel wires that form individual strands laid in a helical pattern around a core. This structure provides strength, flexibility, and the ability to handle bending stresses. Different configurations of the material, wire, and strand structure willMorrison Patent was changed to the Williamsport Wire Rope Company in 1888, manufacturing steel and galvanised wire rope “from one-eighth of an inch to two and one-half inches in diameter, and any length up to two miles in one continuous piece”, according to an 1892 history of Lycoming County.

Distributions of stress and deformation in a braided
A braided wire rope is crossed and braided in a spiral path by groups of single-stranded wire ropes, which are braided together symmetrically, with equal numbers of left- and right-hand lays. Owing to lay angle and rope length influence the fatigue resistance. Most of the tests were terminated before full failure of the ropes. This paper shows that the test termination criterion, such as fracture of the first wire, fracture of 5 % of the wires or full rope fracture, has a large influence on the resulting fatigue resistance.Fatigue resistance of steel ropes: failure criterion Wiley Online

Extra-Flexible Weather-Resistant CoatedCorrosion-Resistant Wire Rope— Not for Lifting. More wires per strand than other wire rope provides the flexibility required for repeat bending over drums and pulleys and the stainless steel wire rope withstands outdoor and washdown applications.Wire Rope: A wire rope is made up of strands wrapped about a core. The core of a wire rope may be fiber rope, solid polymer, or even another wire strand. When the core is a wire strand, it’s called “strand core” or independent wire rope core (IWRC.) Wire ropes are thick, typically 7/16” diameter up to several inches in diameter.Wire Rope vs. Strand: What’s the Difference? LEXCO

Sliding Friction and Wear Characteristics of Wire Rope Contact
Wire rope has different degrees of surface wear under long-distance transmission conditions, which leads to performance degradation and greatly threatens its safety and reliability in service.
