A. Noble & Son Ltd. has been stocking and distributing wire ropealmost since the inception of the company in 1911.

Apart from the distribution of wire rope Nobles personnel cansupply guidance on correct usage and selection of wire rope. Nobles branches throughout Australia have swaging presses forterminating wire rope and NATA accredited tensile testinglaboratories. The testing laboratories can be used for destructiontesting and proof loading of wire ropes and wire rope assemblies.

A. Noble & Son Ltd. represents a range of wire ropemanufacturers from all over the world who each have their ownspecialities in mine winding, crane and general purpose ropes.

Description, Size & Construction

A wire rope is made up of the basic components illustrated. The terms used to describe these component parts should bestrictly adhered to, particularly when reporting on the conditionsof ropes.

Describing wires as strands and strands as wire can be grosslymisleading. For example, a report that a rope has a broken strandin most applications calls for immediate discarding of the rope,and subsequent cessation of operation, while a report that a ropehas a broken wire in it should call for early inspection but seldomfor discarding the rope.

Wire Rope DescriptionThe properties of a wire rope are derived from its size,construction, quality, lay and type of core.

SizeRopes are referred to by a diameter size. The correct way tomeasure wire rope is shown below.

Wire Rope & Strand

GENERAL INFORMATION

ConstructionThe main components of a wire rope are shown below.

In the above example, each individual wire is arranged around acentral wire to form a 7-wire strand. Six of these strands areformed around a central core to make a wire rope. The rope isspecified as 6x7 (6/1) – i.e. six strands each of seven wires.

The size and number of wires in each strand, as well as the sizeand number of strands in the rope greatly affect thecharacteristics of the rope. In general, a large number of small-size wires and strands produce a flexible rope with goodresistance to bending fatigue. The rope construction is alsoimportant for tensile loading (static, live or shock), abrasive wear,crushing, corrosion and rotation.

GENERAL INFORMATION

Multiple Operation: Individual strands are composed ofsuccessive layers of wire laid up at different lay lengths. This results in a cross laid rope.

This type of construction is now confined to a limited range ofproducts such as ropes below 8mm diameter, and large sling andstatic ropes.

Single Operation: All wires in the strand are laid up in the onemanufacturing operation. This type of rope is standard production,providing an equal laid rope that eliminates internal cross-matingand forms a compact strand of high metallic content. There arethree main types: 6x9/9/1, 6x25 FW and 6x36 SW.

Rotation Resistant: The conventional rotation resistant wirerope is composed of a number of strands that are laid up inopposite directions to produce a non-rotating effect.

The 4 strand Mono Track is a complete departure from thisconvention and is created through theoretical analyses of theworking torques.

Triangular Strand: The wires are specially formed to produce a strand with a triangular section – this type of rope is onlyproduced in Lang’s lay. This construction has improved wear andcrush resistance and has wide application in winding and haulagesystems.

Galvanised Strand: These are single strands of concentric layersof wires, some of which are cross laid to produce a non-rotatingresult.

Half Locked Coil: A strand with the outer layer composed ofalternate shaped and round wires covering one or two layers ofround wires laid in the opposite direction.

Full Locked Coil: A strand used as a rope and composed of oneor two layers of Z-shaped wires laid over layers of half lock coiland/or layers of round wires.

Rotation Resistant Mining Ropes: A rope composed offlattened strands of six or eight wires contra laid over a triangularstrand rope to produce a rotation resistant result.

Cores & Wire TensileA number of core types are available and each gives specificproperties to the rope:

1. Fibre Core (FC) – sisal or polypropylene.

2. Wire Strand Core (WSC) – strand usually of the sameconstruction as the outer strands.

3. Independent Wire Rope Core (IWRC) – a wire rope usually of6x7 (6/1)/1x7(6/1) construction.

Fibre Core (FC) in 6x7 ropeA fibre core, generally sisal, provides aresilient foundation for the strands in therope structure. Fibre cores are used forropes that are not subjected to heavyloading and where flexibility in handling isrequired. Fibre cores are inadequate wherewire rope is subjected to heavy loading,prolonged to outdoor exposure andcrushing on small drums and sheaves.

Wire Strand Core (WSC) in 6x7 RopeThese cores are used chiefly for standingropes (guys or rigging), and offer highertensile strength and, owing to the largerwires in the core, greater resistance tocorrosion failure.

Independent Wire Rope Core (IWRC) in 6x25 FW RopeIn many instances it is recommended touse a wire rope with an independent wirerope core (I.W.R.C). Such a core is usuallymade up of 6 strands of 7 wires each pluscentre strand.

GENERAL INFORMATION

The independent wire rope core provides:

1. Permanent support and uniform spacing of the strands laidaround it; it is not compressible and has greater wearresistance than fibre core.

2. Permanent elastic stretch of the wire rope over a longerperiod of time.

3. Increased resistance to deterioration and deformation.

4. Delay of internal corrosion; the lubricant is not squeezed outof the core.

5. It increases the actual breaking load of the rope by at least8% in the case of 6-strand ropes and about 25% in the caseof 8-strand ropes.

6. Better performance for operating in very high temperatures.

An independent wire rope core increases the weight of a 6-strandrope by about 10%, and that of an 8-strand rope by approx. 20%.

Although a new rope with I.W.R.C. may be somewhat less flexiblethan a new rope with fibre core, it retains its relative flexibilitywhereas a rope with fibre core gradually loses its flexibility duringuse. Having better resistance to deterioration and deformation, arope with I.W.R.C. is less susceptible to damage when used onsmall sheaves and drums than a rope with fibre core, it will alsolast longer before deterioration and deformation set in whenwound on a drum in multiple layers.

Tensile Strength GradesWire ropes are usually supplied in the following tensile ranges:

Preforming, Postforming & LayPreformingA preformed rope is one in which the component strands areshaped to their final helical form before being laid into the rope.

Preforming can be applied to both Ordinary lay and Lang’s layropes and, unless specifically ordered otherwise, all standardropes are supplied preformed.

The advantages of preforming are mainly:

1. Reduction of internal stresses in the rope. This makes therope easier to handle, install, reduces its tendency to kink and gives better spooling onto drums.

2. Greatly improved resistance to bending fatigue particularly in operation over small drums and sheaves.

3. Greater stability and better resistance to shock loading and abrasion.

4. Improved rope life due to the better equalisation of loadingbetween strands in the rope and reduction of internal stressesin the rope.

5. Greater safety in handling of ropes as broken wire ends donot protrude. This factor also reduces wear on equipment incontact with the rope.

PostformingPostforming is a manufacturing process applied to ropes tominimise stretch in service. It reduces the stretch caused by"bedding-in" the wires and strands onto their respective cores. In addition to controlling stretch, postforming produces resultsclosely related to those achieved by preforming.Postforming is particularly useful in overcoming stretch in longlengths of rope and where take-up adjustment is restricted. It iscommonly applied to ropes used in aerial ropeways, guying,chairlifts and control cables.

LayThis refers to the way the wires in the strands, and the strands inthe rope are formed into the completed rope. The wire strandsare essentially laid up in a planetary motion with controlled twistbeing imparted to produce a tightly formed rope.

The term "lay" is used in three ways:

1. To describe the direction in which the strands are laid in therope, right or left. In a Right Hand lay strands are laid aroundthe rope core in a clockwise direction – see illustration. In a Left Hand lay, the strands are laid anti-clockwise – see illustration. Steel Wire Ropes are conventionally producedRight Hand lay unless special circumstances require Left Handlay.

2. To describe the direction in which the wires are stranded inrelation to the direction of the strands in the completed rope,e.g. Ordinary lay or Lang’s lay.

Ordinary lay means the wires in a strand are laid in adirection opposite to the direction in which the strands arelaid in the final rope.

Lang’s lay is the reverse of Ordinary lay. That is, the wires arelaid in the same direction as the strands in the rope.

Lang’s lay ropes have superior properties in resistance towear, abrasion, fatigue and scuffing. This is illustrated on thefollowing page, where it can be seen that wear on an outerwire is distributed over a far greater area than in Ordinary lay.

3. "Lay" is also a measure of the pitch of a strand in a rope.

With the increasing use of heavy-duty and more compactequipment (e.g. power winches on mobile cranes and minewinding) there is a gradual upward trend in the required rope wiretensile range. However, as factors other than strength influencethe life of wire rope, the specific application must be kept in mindwhen tensile strength of wire is selected.

Surface FinishThe most common are:Galvanised wire rope - Zinc coated Class B is denoted with B (formerly G).

Galvanised wire rope - Zinc coated Class A is denoted with A (formerly G Class A).

Uncoated or Bright wire rope (Black) - is denoted with U (formerly B).

GENERAL INFORMATION

Characteristics of Lay: The direction of rope lay does not affectthe Breaking Force of a rope. However, the combination of strandlay and rope lay will greatly affect the rope characteristics andthis factor must be taken into consideration when choosing arope. Although the lay length can slightly affect rope behaviourthe dominant aspect that influences performance is the directionof lay and whether it is Lang’s lay or Ordinary lay. For example,the importance of rope lay is evident in a four-part highlift grabwhere rotation of the grab is prevented by the use of alternateright-hand and left-hand ropes.

Lubrication, Specifications, Testing& Plastic CoatingLubricationWhen a rope is operated over a drum or sheave, the strands and wires move relative to one another. To reduce the resultantfriction within the rope as well as the friction between the ropeand drum or sheave, ropes are lubricated in manufacture. In addition this lubrication also retards corrosion and inhibitspossible rotting of the fibre core. In special applications acombination of lubricants may be called for, e.g., the core andinner wires of the strands may be heavily lubricated while thelighter lubrication may be applied to outer wires and strands.

Wire rope cores are normally heavily lubricated irrespective of the outer strand lubrication.

SpecificationsAll standard ropes are produced to generally comply with therequirements of Australian Standards. However some of our more technically advanced wire ropes have special characteristicsrequired to provide superior performance.

Testing & Inspection of Wire RopesNobles can offer special services for rope users to assist in theirinspection of used ropes. Our personnel have in many cases had a lifetime in the industry during which considerable experiencehas been gained.

The NATA accredited tensile laboratories in the various Noblesbranches throughout Australia can provide tensile destructiontesting services, while the company is also accredited by NATA to carry out non-destructive testing on wire ropes in situ.

Plastic Coated Wire RopesPlastic coatings are extruded onto a range of rope and strandedproducts for applications requiring a high resistance to corrosion.Plastic coated ropes are available in the following rope size andconstruction range:

6x7 and 7x7 up to 8mm galvanised6x19 and 7x19 up to 12mm galvanised6x24 up to 12mm galvanised

Typical applications are rigging lines, handrails, steering lines andholding lines in the shipping, pearling and fishing industries.

Plastic coated strands are also available in PVC and blackpolyethylene.

GENERAL INFORMATION

OrderingThe size, grade and construction of a rope must match thespecific application and design factors.

Rope LengthWire rope is manufactured to length tolerances as follows;Up to 400m = +5% - 0%400 to 1000m = +20mOver 1000m = +2% - 0% When a closer length is required, this should be specified in theorder. In calculating rope length requirements, it is advisable toconsider the following practical points for economy in operation:

1. In most cases, mining regulations require a test length be cutat specified periods. Sufficient extra length to cater for suchtests over the expected service life of the rope should beadded to the necessary operating rope length, plus aminimum of 2 1/2 drum turns for anchorage.

2. It is also advisable to make allowance for "cropping" inservice as a consequence of wear or accidental damage at the capel end.

3. In many rope applications, wear and other deterioration areconcentrated in spots along the length of the rope. It is oftenpossible to gain economies in the overall life of the rope byproviding additional length to enable feeding through of thenew rope from the drum to spread the area of wear. Thispractice is regularly used to advantage on cable-operatedearthmoving equipment and oil-well drilling rigs.

4. Short lengths of special rope constructions, if ordered insingle units, can be costly to produce. Consideration of thenumber of such ropes in use and their probable service lifecan often make it more economical to order several suchropes at one time. As a rule, this helps to expedite productionand lessens the possibility of delays in supply.

On existing equipment the rope size is generally fixed by thegrooving of the sheaves and drums. Larger ropes should never beused without modification of drum and sheave grooving to suitthe new rope. It should be remembered that ropes 8mm andabove are made to a diameter tolerance of minus 0% to plus 5%with the exception of 6x24 construction, which has a tolerance ofplus 7%.

ConstructionThe construction of a rope for any given application should besuited to the equipment and to the conditions under which it willoperate. It is important to nominate the construction whenordering. For example, the rope illustrated is ordered as 6x25Filler Wire.

Rope GradeThe minimum tensile strength of the wire is expressed inmegapascals.

Lay of RopeLay affects behaviour and operating life of a wire rope. It isimportant therefore to quote (a) the direction of lay, and (b) thetype of lay and details of the rope application and operatingconditions. The illustration shows a right hand lang’s lay (zZ) orRHLL rope. Ropes are normally supplied right-hand lay.

Rope CoreThe type of rope core must be specified because of the significantdifferences in properties of a wire rope core and fibre core.

Ordering for Special ApplicationsTo obtain the best rope recommended for particular equipmentand operating conditions, information should be supplied onloading, sheave and drum diameters, speed of operation,corrosive conditions and fleet angles etc. A simple sketch of therope rigging is a convenient means of showing this type ofinformation.

All orders should contain information on the above factors.

When purchasers are not sure of the exact requirements thefollowing particulars should be submitted:-

(a) Length and size.(b) Load exclusive of mass of the rope.(c) Dimensions of drums and sheave.(d) Corrosive conditions.(e) Sketch of the application.

Special aspects of rope supply may be necessary

The following check list is suggested:-

(a) Special length considerations such as minimum length, exact length.

(b) Special diameter tolerance.(c) Rope end preparation.(d) End attachments to inside or outside end.(e) Stretch considerations.(f) Special lubricant type and amount.(g) Special reel dimensions, strength, shaft sizes, anchorage

details and lagging.(h) Despatch instructions.

PrestretchingIs the loading of a rope or strand from 33.3% to 50% of itsbreaking load to remove constructional stretch, and this allows forthe more accurate setting of lengths for guying and suspensioncables.

The initial stretch cannot be accurately determined by theoreticalmeans and will continue to take place until it has been completelyremoved.

After this initial stretch (or constructional stretch) has beenremoved the strand will have a truly elastic measure whereelongation is proportional to applied load.

SeizingEither of the following methods of seizing will ensure that therope will later perform its job satisfactorily.

Long Seizing (for ropes over 26mm diameter)

1. Place one end of seizing wire in the valley between strands.2. Take the long end of the wire and turn at right angles to itself

and wind back over itself and the rope in a close tight seizingof the required length.

3. The amount of seizing should not be less than 6 to 8 timesthe rope diameter.

4. Twist the two ends of the wire together. Alternate tighteningand twisting of the ends will draw the seizing up tight.

5. Cut the end of the twisted wires and knock down into a valleybetween two strands.

The above method is best applied using a seizing mallet or bat.

Short Seizing (for ropes below 26mm diameter)

1. Wrap the seizing wire around the rope eight or ten turns.2. Twist the two ends of the seizing wire together approximately

at the centre position of the seizing. Alternate tightening andtwisting of the ends will draw the seizing up tight.

3. Cut the end of the twisted wires and knock down into a valleybetween strands.

The number of seizings required depends on the type anddiameter of the rope. The following minimum number of seizingsare recommended:-

Preformed or Postformed ordinary lay – 1 seizing.

Lang’s lay rope with wire rope core and rotation resistant ropes –2 seizings.

Seizing WireBoth soft annealed single wire and stranded seizing wires areused in the seizing of steel wire ropes. Suitable sizes are listedbelow:-

Transport, Storage & Handling

TransportingRopes are supplied on reels or in coil form. When transporting,care must be taken not to damage rope by contact with othergoods. Reels and coils should be lifted rather than dropped, tippedor rolled, to avoid damage.

Ropes should be uncovered as soon as they are received andchecked for possible transit damage.

StorageRopes, whether on reel or in coils, should be stored on blocks offthe floor to prevent sweating and corrosion and under cover indry conditions free from possible attack by corrosive agents, suchas milldust, sulphur or acid fumes.

GENERAL INFORMATION

If ropes are to be stored for any length of time in warm or hotconditions likely to cause the lubricant to drain to the lower sideof the reel, the reels should be mounted on a horizontal shaft andturned over periodically to maintain uniform lubrication of therope. Additional lubrication may be necessary.

Removed ropes awaiting further use, should be thoroughlycleaned, inspected, lubricated and stored under the sameconditions as new ropes.

HandlingIncorrect handling of rope from reels and coils can result inspringing of wires and strands and kinking of the rope. This typeof damage can seldom be entirely corrected and can greatlyreduce the effective life of the rope.

The drawings show correct and incorrect methods of reeling arope from the transport reel onto a drum or another reel. Thetransport reel should be firmly mounted and braked to preventoverrunning and give tight rewinding. A suitable stand for the reelis also shown.

Methods of removing rope from reels & coilsTurntables, preferably mounted on the floor, may be used forunwinding ropes from reels stored on their sides. Care must betaken to brake such turntables, as over-running could cause therope to slacken, fall off and foul under the turntable.

If a coil is too large to be handled manually it should be mountedon a turntable or suspended by a spindle from a swivel cranehook.

When coiling ropes down by hand on the floor, an occasional coilwound “underhand” relieves torque and provides a more easilyhandled coil. Right Hand lay ropes should be coiled downclockwise, Left Hand lay ropes anti-clockwise.

InstallationRope Equipment CheckingImproved rope performance can be obtained by paying attentionto the following areas:

• Sheaves should be grooved to the nominal rope diameter plusan allowance of 7% to allow for rope manufacturing tolerancesand should be re-machined when worn to nominal diameterplus 3%. Sheaves must also be free from score marks, runfreely and be true.

• Guides and rollers must be free from undersized grooving andbroken flanges, and should run free and true.

• Drum grooves should be checked for size and riser plateschecked for effectiveness.

• Displaced or damaged cheek plates in rope blocks or safetyguards should be repaired.

• Grabbing clutches and brakes should be repaired and adjustedto obviate impact loads on the rope.

• End fittings, such as wedges, sockets and drums anchorages,should be inspected for excessive wear.

The fleet angle has an important bearing on the winding of a rope from sheave to drum, particularly at high operation speeds. If winding is to take place smoothly, the fleet angles on both sides of the drum will have to be kept within acceptable limits.

Excessive fleet angles can result in considerable abrasive damageto both sheave flanges and rope and considerably reduce the lifeof the rope and the equipment.

Fleet angles normally range to a maximum of 1.5˚ for plaindrums and to a maximum of 2.5˚ for grooved drums. Smallerangles are required for high speed haulage such as minewindings. Unless the head or guide sheave is centred with respectto the drum, there will be different values for the left and theright fleet angles.

Rope End PreparationNormally wire ropes are delivered with seized ends. As a rule, nofurther preparation is necessary, but in some cases where ropesmust be reeved through restricted openings, such as drumanchorages and blocks systems, the rope can be supplied withwelded tapered ends or with links welded on the ends. The latterenables the new rope to be installed by attaching it either to theold rope or a tow rope and drawing onto the equipment.

Tensioning RopeWire rope for multi-layer drums must be installed under tension.It is imperative that the bottom layer is tight with the exactnumber of turns on the drum.

Correct method Incorrect method

Correct methods of taking ropesfrom coils: Roll the coil along theground or use a turntable.

Incorrect method: Don’t pullthe rope from a stationary coil.

Correct methods of taking ropes from reels: When a largereel is used, it is recommended that a plank is used as a brakeagainst the reel flange or on the shaft or side plate.

WARNING• When releasing rope from coils or reels, care must be taken to

retard the violent release of the rope end which could causedamage, serious injury or death.

GENERAL INFORMATION

Wire Rope LifeThe main factors, which affect rope life are:

1. Basic design of equipment or installation:

Sheave size, drum design and drum diameter can directlyaffect wire rope life. For example, doubling the sheave sizecan produce up to four times the rope life. The minimumratios in the following table should be adhered to:-

2. Operating Environment:Corrosion – when corrosive conditions exist, regular ropeinspection, particularly of the IWRC, is essential. The effects of corrosion can be partly offset by the use of galvanised wire rope. Temperature – excessively high operating temperatures canlead to deterioration of the wire rope core, and thereby causerope fatigue.

3. Rope Maintenance:End for ending and cropping – in certain applications, e.g.,drag ropes, it is possible to "end for end" the rope. This willgive longer rope life due to the wear points being re-located.If additional rope can be accommodated on the drum, thenprogressive cutting back (cropping) will bring "new" rope intothe system, and will re-locate wear points.Treatment of broken wires – broken wires affecting the lifeof adjacent wires should be removed.Discard practices - clear policies regarding discard shouldbe formulated. Rope Maintenance Schedules, based onexperience, should be drawn up to provide periodicinspections and removal cycles for each rope as well asinspections of individual components such as the sheaves.Regular maintenance ensures optimum rope life, minimisesdown time of plant and equipment and increases theefficiency of the operation.

Broken WiresGeneral purpose ropes, crane ropes and hoist ropes should bediscarded whenever any of the types of degradation exceed thelimits given in the Table below. However, the rope life may beended before these limits are reached.The table below allows for internal wire breaks and is valid for all constructions of rope. In 6-strand and in 8-strand ropes, wirebreaks occur principally at the external surface. This does notapply to wire ropes having a number of layers of strands(typically multistrand constructions), where the majority of wirebreaks occur internally and are therefore non-visible fractures.

Wear All types Outer wires are worn more than one third of their diameter

Loss of area All types The loss of metallic area due to visible combined wire wear andbroken or cracked wires exceeds 10%

Corrosion All types Corrosion is marked by noticeable pitting or loosening of outer wires

NOTES:1. The number of wire breaks before discard in the above table is quite high, and if wire breaks are concentrated in one strand, lower levels for discard are appropriate. If more than

one third of the outer wires in a strand are broken over a length of six times the rope diameter, the rope shall be discarded.2. Where ropes are used for lifts, AS 1735.2 applies, which is less stringent than the above table. The mining industry frequently requires more stringent discard criteria.3. Rope of Lang’s lay construction other than rotation resistant ropes shall have no more than 50% of the above values.4. Number of broken wires alone is not the only factor in discarding a wire rope.

Type of degradation Construction (see Note 3)

Limit of degradation for discard (see Note 4)

Maximum allowable number ofbroken wires over a length of 6times the rope’s diameter

Maximum allowable number ofbroken wires over a length of 30times the rope’s diameter

As such it should be broken in assoon as it is installed, by loading it very lightly for a few cyclesand then gradually stepping up the load, to enable both wires andstrands to ‘bed down’ into the working positions, with the loaddistributed as uniformly as possible.

With strand 6 and 8 stranded ropes, the torque can greatlydiminish after breaking in by releasing the connection andallowing the torque to run out. This procedure may have to berepeated until the constructional stretch has been worked out ofthe rope and it has become neutral.

The use of ‘spinners’ or swivels should be avoided wheneverpossible. All ropes should be reeled onto winch drums as tightlyand uniformly as possible during the initial installation.

InspectionWire rope is tough and durable, but nonetheless expendable and eventually reaches the end of its safe service life. Rope deterioration becomes noticeable through the presence ofbroken wires, surface wear, corrosion, wire or strand distortiondue to mechanical abuse, or drastic reduction in diameter andlengthening of the lay. Also deterioration can be detected by theuse of non-destructive testing techniques. Wire ropes shouldperiodically be inspected for signs of deterioration.

While Statutory Regulations govern the inspection and discardingof certain wire ropes, the same rules cannot be applied to allropes. The proper frequency and degree of inspection dependslargely on the possible risk to personnel and machinery in theevent of rope failure. The determination of the point at which arope should be discarded for reasons of safety requires judgmentand experience in rope inspection in addition to knowledge of theperformance of previous ropes used in the same application.

Where the Statutory Regulations are laid down for the inspectionand discarding of wire ropes and their attachments, wire ropeusers should become fully acquainted with the regulations andsee that they are carried out.

Sufficient records should be kept to provide a reliable history ofthe ropes under their control. Inspection of both operated anddiscarded ropes frequently indicates equipment faults that have a large bearing on the service life and safety of the rope. It istherefore essential to inspect the equipment on which the rope is used as well as the rope itself.

Non Destructive TestingThis method of inspection of wire ropes has become part of themining industries standard requirements for over 20 years. An electromagnetic instrument is used to non-destructivelyexamine the rope. It incorporates a sensor head that is able toinduce a magnetic field in a section of rope that is located withinthe instrument. Changes in the metallic field enable a chart to beproduced showing changes in metallic cross-sectional area andany wire breaks or other anomalies. Life of costly wire ropes maybe extended by this sophisticated method.

DeteriorationTypical examples of wire rope deterioration1. Mechanical damage due to

rope movement over sharpedges whilst under load

2. Localised wear due toabrasion on supportingstructure.

3. Narrow path of wire breakscaused by working in agrossly oversized groove orover small support rollers.

4. Severe wear in Lang’s Lay,caused by abrasion at cross-over points on multi-layercoiling application.

5. Corrosion of severe degreecaused by immersion of ropein water.

6. Typical wire fractures as a result of bend fatigue.

7. Wire fractures at the strand,or core interface, as distinctfrom ‘crown’ fractures causedby failure of core support.

8. Typical example of localisedwear and deformation createdat a previously kinked portionof rope.

9. Multi-strand rope ‘bird caged’due to torsional unbalance.Typical of build-up seen atanchorage end of multi-fallcrane application.

10. Protrusion of IWRC resultingfrom shock loading.

Stretch in RopesWhen load is first applied to a new rope it stretches due to theindividual wires settling down. This is referred to as the Initial orManufacturing Stretch. Subsequently a gradual stretch takes placeduring the whole of the rope’s life; the amount depends on manyvariables such as length, type of construction, loading and themodulus of elasticity of the particular rope.

T = (2W + Lw) ( )L2a E

Where T = Stretch in metresW = Load in kgsL = Length in metresw = Weight of rope in kgs/ metrea = Cross sectional area of rope in millimetres2

E = Modulus of Elasticity, kgs/mm2

To forecast the amount of stretch accurately for a rope under a given set of conditions, calculations must be based on the resultof a load/extension test on a sample from the particular rope.However, if the results of such a test are not available, an indication of the increase in length can be obtained from the formula.

BREAKING FORCE TABLES

The following tables show rope mass in "kg per 100 metres" andbreaking force in "kilonewtons" for the various rope groups.

It will be noted that the value varies from group to group sincethe various constructions contain different steel areas and variablelosses are incurred as the result of the stranding of the wires.

Wire quality has been nominated in 1570, 1770 and 1960 gradefor the majority of wire ropes, the value 1570, 1770 etc.corresponds to the minimum tensile strength of the wireexpressed in megapascals. Marine and General Purposegalvanised ropes have been nominated in 1570 grade and areconfined to certain rope constructions. Other 6 strandconstructions in galvanised rope should be ordered in 1770 grade.

The breaking forces of rope of tensile grades other than 1770 canbe calculated by multiplying the value of 1770 grade by the ratioof the grade number. The grade of 2070 is the preferred hightensile grade for 6 strand ropes but 1960 is preferred for 19x7,35x7 and most Casar ropes.

All ropes are in millimeter diameter. Only preferred sizes havebeen included in the tables. Non preferred sizes should be thesubject of special inquiry. Special non preferred sizes to suitexisting deep mining and large excavator equipment are availablealthough new equipment should use only preferred diameters.

The breaking force unit is the kilonewton, this being the forcewhich, applied to a mass of one kilogram, produces anacceleration of one metre per second. The minimum ropebreaking force required will depend on the factor of safetycovered by the application and in the case of a single supportingrope where the rope mass is ignored will be equal to thegravitational force multiplied by the factor of safety. Minimumrope breaking force (kN) = Mass (tonnes) per rope part x factorof safety required x 9.81.To calculate approximate mass equivalent, at sea level, divide kilonewtons by 9.81Example: 12mm 6 x 7 Fibre Core G1570 grade

= 75 kN = = 7.65 tonnes

For most practical purposes, divide by 10 in lieu of 9.81

Rotation Resistant 4 x 39 (SES) Mono TrackIt is well known that wire ropes tend to spin or rotate under load.This can cause damage to the wire rope or load, work delays and

4 x 39 (SES)

a hazardous environment. To overcome this problem a 4-strandrope with a unique construction has been designed.These rotation resistant wire ropes are commonly used in theconstruction industry to minimise rotation in single and multi-parthoisting systems.

CASAR SPECIAL MINING WIRE ROPES

Hoisting ropes in underground mining operations play avital role in the production cycle, not only to hoistminerals but also to transport men and materials safelyand efficiently. Winding ropes are therefore clearlysafety critical throughout their operating life.

Casar specialises in this technology and is a worldleader in the manufacture of sophisticated wire ropeproducts for a broad range of lifting applications. InAustralia Casar has established a strong position in themining industry.

Quality and high tech designEvery effort is made to maintain and improve thequality of Casar wire rope products for the miningindustry. Careful attention to quality and engineeringdesign details ensures that a Casar rope will routinelyoutperform conventional six strand and rotationresistant ropes. Special features of Casar mining ropesinclude galvanising, compacted strands and a plasticlayer between steel core and the outer strands. Theinternal plastic layer stabilises the construction andexperience has shown that Casar winding ropes are lessprone to torsional distortions like waviness and slackouter strands.

Reliability and value for moneyCasar Special Mining Ropes offer benefits such asincreased reliability of the hoisting system and reduceddowntime due to less servicing and fewer rope changes.The higher breaking strengths of Casar Special MiningRopes allow for an increase of payload for the same

diameter. The increased capacity of the shaft will lead toincreased profitability of the mine.

How to select the most suitable designThis catalogue sets out a range of different minehoisting applications that Casar ropes can be used forand identifies which rope construction should be used inparticular circumstances.

In order to assist you in rope selection, tables thatfollow give factors that can be used to calculate forexample the rope minimum breaking loads (MBL) andmasses for a given rope diameter. This allows forautomated rope diameter selection given basic windingsystem parameters. The detailed specifications ofvarious Casar mining ropes are given in 1mm diameterincrements, but with rope factors it is also possible tocalculate the rope specifications for intermediatediameters, e.g. 42.5mm or 53.5mm, which Casar canmanufacture on request.

Tailor made rope constructionWithin a particular rope construction family Casar areable to deliver a wide range of fill factors and strengthto mass ratios. An example of this is the comparisonbetween Starplast M (with no compacted strands) andStarplast VM (with fully compacted strands). By varyingthe degree of strand compaction, Casar canmanufacture ropes with every metallic cross sectionalarea, any breaking strength or any specific weightbetween the figures of Starplast M and Starplast VM.We are therefore able to adapt the rope specifications tothe exact requirements of your shaft. This is the corecompetence of Casar.

TYPICAL MINE WINDERS

Koepe friction winders are either installed in aground or tower mounted configuration. The numberof head and tail rope pairs can vary between 1 and 10depending on the hoisting duty of the winder. In generalthe combined unit mass of the head and tail ropes areequal to ensure balanced winding. Single layer ropeconstructions are widely used for shallower shaft Koepe

winders, but for depths exceeding 900 m it is criticalthat non-spin or rotation resistance constructions areused. For free looping tail ropes, non-spin ropes withswivels under both conveyances are recommended.For multi-rope winders, rope load balancing and equaldriving sheave/drum circumferences are critical toensure good rope life.

Double drum and BMR winders are almost alwaysground mounted. For these winders, single layer ropeconstructions can be used even in very deep shafts ineven in excess of 3000 m. However, in such cases thelay length changes from the manufactured state wouldbe significant. Rope load balancing and accurate drumspooling between rope pairs are critical on BMRwinders. Ropes which offer high drum crushing

resistance are preferred for these applications as theropes normally deteriorate first at the _ turn and layercrossovers on parrellel grooved drums. In cases wherethe ropes are free to rotate during the winding cycle(e.g. kibble winders) or where the shaft uses ropeguides, non-spin or rotation resistant constructionsare used.

ONESTEEL FISHING WIRE ROPES

The OneSteel range of fishing ropes are characterised by the veryhigh levels of galvanising achieved in the high strength 1770 MPagrade wire. Galvanising levels at 25% above Class A (now ClassW10Z to AS/NZS 4534) are targeted in manufacture.

OneSteel refer to these as marine grade galvanised wire products.This along with the special treatment that ropes receive inmanufacture to prevent nicking and marking the zinc ensuresa product that is highly resistant to corrosion. The product ispopular for warps and bridles in trawling.

Rope cores are lubricated laid polypropylene for best results. Also the rope strands are lubricated in manufacture using a wax

base lubricant with extreme pressure additives and corrosioninhibitors. In accord with occupational health and environmentalprinciples the use of bitumastic based lubricants has beendiscontinued.

Note:• Information on other rope sizes, constructions and compak

fishing ropes are available on request.• There is a limit to the wire size available with the marine grade

levels of galvanising in high strength 1770 MPa grade. In largersizes these may need to be of 1570 grade tensile wire to obtainthe same high levels of galvanising.

1770 Grade Wire is standard, 1570 may be available upon request.

Kiswire fishing ropes are available in both A & B galvanising andALUMAR. ALUMAR fishing ropes have 5% aluminium in the zincgalvanising mix with the inclusion of the aluminium ensuringsuperior resistance to corrosion and a longer working life.

ALUMAR ropes have performed extremely well in laboratory Salt Spray (NaCI) and SO2 Atmosphere humidity tests.

These test indicate that ALUMAR technology improves corrosionresistance by approximately 3 times. ALUMAR fishing ropes are theend product of many years of testing in regard to the correct levelof aluminium to be included in the zinc mix. The level of 5%provides the optimum balance of corrosion resistance, durability and working life.

STAINLESS STEEL WIRE ROPE

7 x 197x19 is the most common and versatile construction of stainlesssteel wire rope. It consists of 7 strands each with 19 wires and is the most flexible and the easiest construction to work withparticularly where the rope needs to turn corners, changedirections or where ferrule secured thimble eyes and wire ropegrips are used. 7x19 can be used in either fixed rigging or forlimited working rope applications such as on a boat winch.

7 x 77x7 consists of 7 strands each with 7 wires and is not as flexibleas 7x19. 7x7 is an excellent choice for fixed rigging applicationssuch as balustrading and safety barrier rails. Although 7x7 isstiffer than 7x19 it is still capable of limited angles and can beused with thimble eyes or swage fittings. 7x7 has very limitedapplications as a running or working rope.

1 x 191x19 consists of a single strand with 19 wires. 1x19 is very stiffand is suitable for fixed "straight line" rigging only such as maststays, guy ropes and structural applications. It cannot be usedwith thimble eyes and is best utilised and looks very effective withmachine swaged end fittings.

There are three common constructions of stainless steel wire ropeused in fixed rigging applications. Nobles stock stainless steel wirerope mainly in 316 grade but some 304 grade product isavailable.
