This catalogue is designed to provide a non-techni-cal guide to the selection of a suitable wire rope forvarious applications. Technical information is re-stricted to weights and breaking loads and a few for-mulae. Constructions and sizes shown here are thosecommonly available and used in New Zealand butthere are many others and enquiries for special ap-plications should be directed to your nearest Cookesbranch.Wire Rope is a machine of many working parts andlike most machines it must be made right, selectedright for the application and used correctly in thatapplication. Like many machines, there is a greatvariety of types of wire rope, each with different prop-erties to suit it’s intended use. The internal combus-tion engine used to power a racing car is quite differ-ent to the one powering a large truck although theyboth may produce the same horsepower. Like manymachines it is impossible to combine the advantagesof each type into one single machine. The high horse-power and low weight of a racing engine would begreat in a truck. The high fuel cost and short life wouldnot. The same with wire rope, the attributes that makeone construction eminently suitable for one applica-tion could well be a total disaster in another.

COOKESWIRE ROPE DESIGN & CONSTRUCTION
Wire ropes are composed of independent parts - wires,strands and cores - that interact with each other dur-ing service.
Wire rope engineers design those parts in differentsteel grades, finishes and a variety of constructionsto attain the best balance of strength, abrasion resis-tance, crush resistance, bending fatigue resistance andcorrosion resistance for each application.
To select the best wire rope for each application, onemust know the required performance characteristicsfor the job and enough about wire rope design to se-lect the optimum combination of wire rope proper-ties.
The following information is provided as a basicguide. Our expert in house staff and field service spe-cialists are available to provide more specific rec-ommendations.
11
COOKESThe three attributes of a wire rope to consider are:(1) Strength.(2) Flexibility.(3) Robustness.In all dynamic rope applications (as opposed to staticapplications such as guy wires etc.) the choice is in-variably a compromise.
Strength can be increased by increasing the diameterof the wire rope and/or increasing the tensile strengthof the individual wires and/or increasing the crosssectional steel content (by decreasing the air voidsbetween the wires) and/or using a steel core construc-tion.
Flexibility can be increased by using more wires of asmaller diameter and/or decreasing the tensilestrength of the individual wires and/or using a fibrecore.
Robustness, or resistance to physical damage, canbe increased by using fewer wires of a larger diam-eter and/or using a steel core and/or by increasingthe steel area exposed to sources of external dam-age. Coatings such as galvanizing or others can beapplied to protect against corrosion.
12
COOKES
In almost all cases improving one attribute dis-tracts from another. In addition the wire rope’s work-place is rarely ideal. Apart from the environment (dirt,dust, moisture and chemicals), the equipment towhich the rope is fitted is rarely ideal and another setof compromises must be decided on. For example allwire rope suffers from being bent and the smaller thebend radius the shorter the rope life. For a 26mmwire rope to escape bend fatigue the winch drum orblock sheaves over which it runs would need a mini-mum diameter of over 1.5 metres. This is clearlyimpractical in many applications, and unnecessary ifbend fatigue does not cause the ultimate demise ofthe rope.

TERMINOLOGYWire rope consists of a number of strands laid upusually over a central core. Each strand is madefrom a number of individual wires.
CORESAlmost all wire rope is laid up over a core, FibreCore (natural or synthetic), Independent Wire RopeCore or Wire Strand Core (FC, IWRC or WSC):

COOKESSTRAND CONSTRUCTIONS.
Strands are designed with various combinations ofwires and wire sizes to produce the desired resistanceto fatigue and abrasion. Generally, a small numberof large wires will be more abrasion resistant andless fatigue resistant than a large number of smallwires.
SingleSize
The basic strand has wiresof the same size woundaround a centre.
Seale
Large outer wires with thesame number of small innerwires around a core wire.Provides excellent abrasionresistance but less fatigueresistance. When used withan IWRC, it offers excellentcrush resistance overdrums.
FillerWire
Small wires fill spacesbetween large wires toproduce crush resistanceand a good balance ofstrength, flexibility andresistance to abrasion

Bright finish is suitable for most applications. Gal-vanized finish is available for corrosive environments.Plastic jacketing is also available on some construc-tions.
WIRE GRADESThe most common steel wire grades are: 1420-1770N/mm², and 1860N/mm². Stainless steels and otherspecial grades are provided for special applications.Most wire ropes are made with round wires. Bothtriangular and shaped wires are also used for specialconstructions.Generally, the higher the strength of the wire, thelower it’s ductility will be.

COOKESAs with all engineering design proplems, feasiblesolutions demand compromise to some degree. Attimes is becomes neccessary to settle for less thanoptimum resistance to abrasion in order to obtain themaximum flexibility: the latter being a more impor-tant requirement for a given job. A typical exampleof this kind of trade-off would be in selecting a highlyflexible rope on an overhead crane. Conversly, in ahaulage installation, a rope with greater resistance toabrasion would be chosen despite the fact that suchropes are markedly less flexible.Two compelling factors that govern most decisionsas to the selection of a wire rope are abrasion resis-tance and resistance to bending fatigue. Striking aproper balance with respect to these two importantcharacteristics demands judgement of a very highorder. A graphic presentation of just such compari-son of qualities between the most widely used ropeconstructions and others is given by means of an X-chart.Referring to this chart when selecting a rope, themidpoint (at the X) comes close to an even balancebetween abrasion resistance and resistance to bend-ing fatigue. Reading up or down along either leg ofthe X, the inverse relationship becomes more appar-ent as one quality increases and the other decreases.See next page.

EFFECT OF SHEAVE SIZEWire Ropes are Manufactured in a great variety ofconstructions to meet the varying demands of wirerope usage. Where abrasion is an important factor,the rope must be made of a coarse construction con-taining relatively large wires. In other cases, the greatamount of bending to which a rope is subjected ismore important. Here, a more flexible construction,containing many relatively small wires, is required.In either case, however, if the rope operates over in-adequate size sheaves, the severe bending stressesimposed will cause the wires to break from fatigue,even though actual wear is slight. The smaller thediameter of the sheave, the sooner these fatigue breakswill occur and the shorter rope life becomes.Another undesirable effect of small sheaves is accel-erated wear of both rope and sheave groove. The pres-sure per unit of rope on sheave for a given load isinversely proportional to the size of the sheave. Inother words the smaller the sheave the greater therope pressure per unit area on the groove. Using theproper diameter sheave for the size and constructionof rope can obviously prolong both sheave and ropelife.Sheave diameter can also influence rope strength.When a wire rope is bent around a sheave, there is aloss of effective strength.
22
COOKESThis is due to the inability of the individual strandsand wires to adjust themselves entirely to theirchanged position. Tests show that rope strength effi-ciency decreases to a marked degree as the sheavediameter is reduced with with respect to the diam-eter of the rope.Therefore, it is evident that a definite relationshipexists between rope service and sheave size. As aguide to rope users, wire rope manufacturers haveestablished standards for sheave sizes to be used withvarious rope constructions. To secure the most eco-nomical service, it is important that the suggestedsize of sheaves given on the following page be used.As a rope is run through a groove, both becomesmaller. A used groove can be too small for a newrope, thus accelerating rope wear. A compromisebetween rope life and machining frequency must bemade.Grooves should have an arc of contact with the wirerope between 135 and 150 degrees. They should betapered to permit the rope to enter and leave thegroove smoothly. Field inspection groove gauges aremade to the nominal diameter of the rope plus 1/2 ofthe allowable rope oversize tolerance. When the
gauge fits perfectly, the groove isat the minimum permissible con-tour

COOKESDRUM WINDING
It is very important to have a rope wind evenlyand tightly on a smooth drum. Due to lay directionand tension, rope has a tendency to rotate or roll as itapproaches a winch drum. This characteristic is usedto advantage by establishing the winding directionand dead end location so the rope will rotate in thedirection of the preceding wrap. Tightly packed wrapson the all-important first layer will ensure properwinding for additional layers.
If the drum attachment and direction of wrapsare not correctly selected, the first layer of rope willnot wind evenly or tightly, causing the second layerto pinch down between the wraps of the first layer.The resultant uneven winding will become worse witheach succeeding layer and result in abnormal scuff-ing and abrasion. If there are sufficient layers the ropewill pile up and “fall over” on itself with disastrousresults.
The hand rule is a convenient way to checkthe correct lay for an installation. The extended thumbpoints to the flange to which the rope is terminatedwhile the extended forefinger represents the ropeleaving the drum. A palm up hand representsunderwind and palm down overwind. If the right handmeets the conditions, use right hand lay rope and viceversa.

FLEET ANGLEExcessive fleet angles can cause serious
damage to wire rope, sheaves and grooved drums.Severe scuffing results when rope wears againstgroove walls, grinding them down causing the ropeto become bruised and crushed.
Fleet angles on equip-ment should preferablybe kept between 1° and1.5° and should notexceed 2° for smoothdrums or 4° for grooveddrums. To ensure therope crossing back andstarting the second layerproperly withoutassistance the fleetangle should not be lessthan 1°.The fleet angle is thatangle between thecentre line of the firstfixed sheave and thecentre line of the ropeleading to the drum.

Under static conditions the tension in eachpart of a rope in a multi-reeved system will be thetotal load to be lifted divided by the number ofparts supporting the load. When the load is raised itis necessary to take into account forces required toovercome friction in the sheave bearings and theresistance to bending of the rope as it passes overthe sheave. These additional forces are cumulativeand vary with the type of bearing and the sheavetread:rope diameter ratio.

COOKESSAFE WORKING LOADS
The safe working load (SWL) of a wire ropeor a sling made from it is calculated by dividingthe particular wire rope’s minimum breaking load(MBL) by the safety factor to be used. This safetyfactor depends on the application and may bedetermined by legislation or other codes of prac-tice. A common safety factor is 5:1 which meansthe SWL of the rope is 1/5th of it’s MBL. Wherethe load is evenly supported by more than onelength of rope the SWL can be increased as shown:
Load carriedon two parts
at 90°= SWL x 1.4
Load carriedequally on two parts
at 30º = SWL x 2at 60º = SWL x 1.8at 90º = SWL x 1.4at 120º = SWL x 1
Load carriedon two parts= SWL x .8
Load carriedon four parts
at 90°= SWL x 2.1
30
COOKESIncorrect installation or handling prior to in-
stallation can damage a wire rope and cause failurebefore it is even put to work. Care must be taken toavoid putting a kink in the rope and thus permanentlydamaging it. DO NOT lie the coil on it’s side or thereel on it’s flange and lift the wraps off the top! Thefollowing illustrations demonstrate correct methods:
31
COOKES
32
COOKES
Ensure that wire rope always passes aroundwinch drums and sheaves in the same direction (al-ways clockwise or always anticlockwise) and ensurethat the rope is loaded to equipment in the same di-rection as supplied i.e. top of reel (or coil) to top ofwinch drum or bottom to bottom, never top to bot-tom or vice versa:
