WIRE ROPE - Interplus1999

WIRE ROPEAll wire rope is manufactured with three basic components: Wires,Strand and Core. Following is a description on the essentialinformation required for ordering wire rope.DIAMETERNominal Diameter is always measured from its widest point as perdiagram. The diameter of wire rope is manufactured with a tolerance of0% to plus 5%.CorrectIncorrectCONSTRUCTIONWire rope is manufactured with individual wires which are helically laidtogether to form a strand. It is defined by the number of strands perrope, and number of wires in each strand. For instance a 6 x 26 wirerope denotes 6 stranded rope, with each strand containing 26 wires.The number of strands and wires in a wire rope will influence theflexibility of the wire rope. Generally the more wires in the rope thegreater the flexibility, however the smaller the wires the less abrasionresistance.SPECIFICATIONS SUBJECT TO CHANGE WITHOUT NOTICEIndustries Ltd.WARNING: NEVER EXCEED WORKING LOAD LIMITSPAGE 2

CoreWire RopeStrandWireCOREWire ropes are supplied with either a fibre core or steel core. The coreprovides the stability to the outside strands and several different typesare available:FIBRE CORE: A fibre core is generally manufactured with a naturalmaterial such as Sisal, or a synthetic fibre such as polypropylene.Fibre cores are generally used for ropes where flexibility in handling isrequired. The fibre core is impregnated with lubricant beforemanufacture, it then continues as an internal lubricator during theoperation of the rope. Fibre core ropes are inadequate where they aresubject to crushing on small drums and sheaves.STEEL CORE: A steel core can be either Independent Wire Rope Core(IWRC) or Wire Strand Core (WSC). IWRC is a small independent coreand is commonly manufactured from seven strands, and WSC which isoccasionally used, is manufactured from either seven or nineteenwires. Steel cores are used to add strength to the rope and to provideresistance to drum crushing.LAYThe spirals or helical twist of the wires and strands is referred to as thelay.SPECIFICATIONS SUBJECT TO CHANGE WITHOUT NOTICEIndustries Ltd.WARNING: NEVER EXCEED WORKING LOAD LIMITSPAGE 3

REGULAR LAY: Is used to describe rope with wires in a strand that arelaid in a direction opposite to the direction of the formed strands. Dueto the shorter length of exposed outer wires a regular lay rope is lesssubject to failure from crushing and distortion.LANG LAY: Describes ropes in which both the direction of the wiresand strands are the same. A lang lay rope has greater flexibility andabrasion resistance because of the longer length of exposed outerwires. However, great care should be used when recommending andhandling lang lay rope.RIGHT OR LEFT LAY: Refers to the direction in which the strands twistor rotate around the wire. Ropes in a clockwise direction are righthand lay and ropes in left hand lay are laid in an anti-clockwisedirection.Right Hand Regular LayLeft Hand Regular LayNOTE: WIRE ROPES ARE SUPPLIED AS RIGHT HAND REGULAR LAYUNLESS OTHERWISE SPECIFIED.SPECIFICATIONS SUBJECT TO CHANGE WITHOUT NOTICEIndustries Ltd.WARNING: NEVER EXCEED WORKING LOAD LIMITSPAGE 4

GRADEWire rope can be supplied in several different grades. The grade ofwire rope affects the ultimate breaking strength of the wire rope but willalso influence the life of the rope. Common grades available areImproved Plow Steel (IPS), Extra Improved Plow Steel (EIPS) and ExtraExtra Improved Plow Steel (EEIPS). EIPS is the most commonmanufactured and supplied grade today.Wire ropes are now also available as Compacted or Swage ropes. Thecompaction of wire ropes increases the metallic area of the ropeallowing for a higher breaking strength as well as improved life fromincreased drum and abrasion resistance. Swage ropes are designed togive superior strength and abrasion resistance and is generally suitedto logging industry, and it is not normally suited to regular crane usebecause the rope deteriorates from the inside out.FINISHWire Ropes can be specified as either Bright, Galvanized or StainlessSteel. Most running ropes are supplied Bright finish unless a corrosiveor harsh environment is present, and standing rope are usuallygalvanized. Stainless steel is commonly used in marine environments.Wire ropes are lubricated at time of manufacture. The lubrication helpsreduce friction between wires and strands, and the friction between therope and drum or sheave. In addition the lubrication retards corrosionand inhibits possible rotting of the fibre core. Upon customersrequests, additional lubrication can be supplied at time of order, orWesco Industries can supply wire rope lubricant which can be appliedduring the life of the rope.Wire ropes can also be supplied with plastic coatings. Plastic coatingsare extruded onto a range of wire rope products, and is available inPVC or Nylon coating.SPECIFICATIONS SUBJECT TO CHANGE WITHOUT NOTICEIndustries Ltd.WARNING: NEVER EXCEED WORKING LOAD LIMITSPAGE 5

With the increase in technologies wire ropes can now be supplied withplastic layers internally. The plastic layer between the steel core andthe outer strands inhibits inter strand wear, seals the lubricant insidethe core, keeps water and abrasive materials from penetrating the ropeand reduces the incidence of birdcaging.ROTATING ORROTATION RESISTANT?Wire rope will tend to spin or rotate under load. Therefore it isimportant to determine if a rotation resistant wire rope is required.Rotation resistant wire ropes are manufactured to allow the rotationalforce of the outer strands to partially counteract the rotational forces ofthe inner strands. Single part and some multi part operations must userotation resistant wire ropes when lifting unguided loads.COMMON ABBREVIATIONSRHRL Right Hand Regular LayLHRL Left Hand Regular LayRHLL Right Hand Langs LayLHLL Left Hand Langs LayRHAL Right Hand Alternate LayNRNon RotatingFC/HC Fibre Core/Hemp CoreIWRC Independent Wire Rope CoreIPS Improved Plow SteelEIPS Extra Improved Plow SteelEEIPSExtra Extra Improved Plow SteelSPECIFICATIONS SUBJECT TO CHANGE WITHOUT NOTICEIndustries Ltd.WARNING: NEVER EXCEED WORKING LOAD LIMITSPAGE 6
