1.1 Quality in material
The steel wires used in manufacturing a Cimaf rope are submitted to the strictest testscorresponding to the most demanding specifications used in manufacturing wire ropes.The materials approved by this testing ensure the safety and the good quality of thefinished product.
Conventionally, the wire ropes can be manufactured in some traction resistancecategories, namely:

Note: The bright wire ropes in the gauges between 6.4 mm and 52 mm, have theFaixa Amarela[Yellow Stripe] identification (a strand lubricated with yellow grease)except for specific uses, such as, for instance: ropes for passenger elevators, high
performance cables and others.
Another current manufacture product is the wire rope for elevators. The quality of the steelfor this product is special, gathering the characteristics required to withstand the stresseswhich take place in the elevator facilities.
Galvanized ropes (Zinc coated)
Wire ropes subject to aggressive environments or in contact with water, require anadditional protection against corrosion.
Cimaf manufactures the wire ropes galvanized with wires which have a uniform layer ofzinc, which can by applied by a process of fire or electrolytic zinc plating.
Galvanization of these wires can be done in the final gauge or in an intermediary gaugeand later, it is drawn again, providing an uniform zinc layer. The intermediary gaugegalvanized wires are called redrawn galvanizedwires.
The Cimaf wire ropes produced with galvanized wires have the same resistance to tractionas the bright wire ropes on the strength range.
The initials PS, IPS, EIPS and EEIPS refer to the first stages of development of the wireropes and remain until today. The Plow Steel resistance curve forms the basis forcalculating the wire strengths.
As it can be observed in the graph, the wire traction resistance for each category is notconstant, varying inversely to their diameter.
The categories are also characterized by the quality of elasticity, resistance to traction andto abrasion, which importance will depend on the application of the wire ropes.
However, the modern trend in manufacturing wire ropes is to obtain a product whichgathers all these characteristics in the highest possible degree.
The wire ropes manufactured in the SHT category are manufactured with steel core(IWRC), being recommended for special applications, where a great resistance to tractionis required, having limitations of mass and diameter. It is a rope of maximum duration,resistance and responsibility.
Main advantages of the SHT wire rope:
1 - Rupture load 10% greater than the EEIPS category, enabling the increase of loadcapacity, without increasing the diameter of the wire rope.
2 - Insurmountable resistance to abrasion, kneading and shock.
It is worthwhile to remember that resistance to traction is not the only factor to be takeninto account when specifying the ropes. Thus, Cimaf produces wire ropes especiallydeveloped for such applications as: passenger elevator, overhead crane, oil rig, winch,work site elevator, among others.

2.1 Constructions and lay types
Construction is a term employed to indicate the number of strands, the number of wires ineach strand and its composition, as we will see next:
2.1.1 Number of strands and number of wires in each
strand
(por exemplo: o cabo 6 X 19 possui 6 pernas com 19strand
(for instance: rope 6 X 19 has 6 strands com 19 wireseach).
The strands for the wire ropes can be manufacturedin one, two or more operations, according to theircomposition. In the early manufacturing of wire ropes,the usual compositions of the wires in the strands were inmultiple operations, with wires of the diameter, such as: 1+ 6/12 (2 operations) or 1 + 6/12/18 (3 operations).
So, at first, 6 wires were twisted around a central wire.
Later, in a new passage, the core (1 + 6) wires werecovered with 12 wires

In single composition, all the wires have the samediameter.
In the Sealecomposition there are at least two adjacentlayers with the same number of wires. All the wires of theexternal layer in this composition have greater diameter toincrease the resistance to wear caused by friction.
TheFiller composition has very thin wires between thetwo layers. This condition increases the area of contact,flexibility, resistance to kneading and reduces wearbetween the wires.
Warringtonis the composition where there is at least onelayer built of wires of two different and alternate diameters.Wire ropes manufactured with this composition have agood resistance to wear and a good resistance to fatigue.
On the other hand, there are still other kinds ofcompositions which are formed by agglutinations of thementioned above, such as, for instance, the Warrington-Seale composition, which has the main characteristics ofeach composition, providing the rope a high resistance
to abrasion conjugated with a high resistance to bendingfatigue.
With the improvement of manufacturing techniques, machines and constructions of ropeswere developed which enabled us the confection of strands in a single operation, all thelayers being in the same pitch.
So the following compositions appeared Seale, Filler and Warrington, formedby wires of different diameters. These compositions present great advantages over
the strands manufactured in multiple operations for they eliminate their advantages asmentioned above.
Fatigue testing has shown that wire ropes with strands manufactured in a single operationhave greater durability to those of the wire ropes manufactured in multiple operations.

2.1.3 Direction and Lay Type
When the strands are laid from left to right, it issaid that the wire rope is right lay (Z).
When the strands are laid from right to left, it issaid that the wire rope is left lay (S).
The use of the left lay rope is uncommon in themajority of applications. All the characteristicsof the application must be considered beforespecifying a left rope.
In theregular lay rope,the strand wires arelaid in the opposite direction to the lay of thestrands themselves. As a result, the wiresfrom the top of the strands are positionedapproximately parallel to the longitudinal axisof the wire rope. These ropes are stable, have
a good resistance to internal wear and twisting and are easy to handle. They also have aconsiderable resistance to kneading and warping due to short length of the exposed wires.
In the Lang lay rope,the strand wires are laid in the same direction to the lay of thestrands themselves. The external wires are positioned diagonally to the longitudinal axisof the wire rope and with a greater exposure length than in the regular lay. Due to thefact of the external wires having a greater area exposed, the Lang lay provides greaterresistance to abrasion to the wire rope. They are also more flexible and have greater
resistance to fatigue. They are also more subject to internal wear, distortion and warpingand have a low resistance to kneading. Moreover, the Lang lay wire rope must always have
their ends permanently attached to prevent their distortion and, on this account, are notrecommended to move loads with only a single line of rope.
Note: Except for special cases (such as, for instance, airlines tractor rope), Lang layropes with fibre core must not be used on account of presenting poor stability and smallresistance to kneading.
2.1.2 Core type
The core of a wire rope is a nucleus around which the strands are layed and are arranged ina helix manner. Its main function is to make the strands be positioned in such a manner that
the stress applied in the wire rope is distributed uniformly between them. The core can becomprised of either natural or synthetic fibre; it can also be formed by a single strand or byan independent Wire rope.
Almas de fibra:Fibre cores in general provide greater flexibility to the wire rope. The Cimafwire ropes can have cores made of natural fibres (FC) or synthetic fibres (SFC). The naturalfibre cores are normally made of sisal, and the synthetic fibre cores are usually made ofpolypropylene.
Almas de ao: The steel cores ensure greater resistance to kneading and increaseresistance to traction. The wire rope can be formed by a single strand of rope (WSC) or byan independent wire rope (IWRC), this latter mode being preferred when greater flexibility isrequired from the rope, combined with high resistance to traction. Wire ropes with diameterequal to or above 6.4 mm, when provided with steel core, are the IWRC type.
A 6-strand rope with steel core presents approximately an increase of 7.5% in its loadcapacity in the IPS category and approximately an increase of 12.5% in load capacity in the
EIPS category in relation to a rope with fibre core of the same diameter and construction.Its mass also has an increase of approximately 10%.

2.2 Rope lay length
It is defined as lay length of a wire rope the distance, measured parallel to the rope axis,required so that a strand makes a full turn around the rope axis.
2.3 Lubrification
Rope lubrication is very impor tant for its protection against corrosion and also to reducewear by friction by the relative movement of its strands, the wires and the wire ropeagainst the equipment parts, such as, for instance, sheaves and drums.
The Cimaf wire ropes are lubricated during the manufacturing process as a lubricantcomposed especially for each kind of application.
This lubrication is adequate only for a storage period and operations start-up of thewire rope.
For good rope conservation, it is recommended to lubricate it on a regular basis.
If an adequate lubrication plan is not carried out, the wire rope will be subject to:
The occurrence of oxidation with porosity causing loss of metal area and,consequently, loss of load capacity;
The wires start to become brittle, due to the excess corrosion;
As the wire rope wires move relatively against one another, during use, they are subjectto wear by friction. Lack of lubrication intensifies wear, causing loss of wire ropecapacity caused by loss of metal area;
Porosity also causes internal wear of the wires, resulting in loss of load capacity.
Lubrication of a wire rope is just as important as lubrication of a machine.
Never use burnt oil to lubricate a Wire rope, for it contains small metal particles which willcause friction with the rope, in addition to being an acid product and contain few of thecharacteristics which a good lubricant must have.

LAY LENGTH
A lubricant which is adequate for wire rope must have the following characteristics:
To be chemically neutral;
To have good adherence;
To have viscosity capable of penetrating between the strands and other wires;
To be stable under operational conditions;
To protect against corrosion;
To be compatible with the original lubricant.
Before re-lubrication, the rope must be cleaned with a steel brush to remove the old
lubricant and crusts containing abrasive par ticles. Never use solvents, for they remove theinternal lubrication, in addition to deteriorating the fibre core.
The rope must be re-lubricated just after being cleaned.
Due to the small space between the strand wires and the strands in the wire rope, duringre-lubrication, the lubricant being applied will have difficulty in fully penetrating the wirerope.
As a general rule, the most efficient and cost-effective form of re-lubrication is througha method which applies the lubricant continuously during the rope operation, such as:immersion, dripping and spraying.
It is recommended that the lubricant application point is preferably where the wire ropepasses through sheaves or drums, for at this moment, an opening occurs between thestrands on the top part of the wire rope, favoring lubricant penetration.
In the table below we suggest a few lubricants, for field re-lubrication.
notes:
The performance of the lubricants from the table was analyzed in the eld. Othersimilar specications can be used.
These lubricants are not commercialized by Cimaf.

2.5 Wire rope strength
The aggregate breaking forceof the wire rope is obtained by means of the wire strengthmultiplied by the total section area of all the wires.
The minimum breaking forceof the wire rope is obtained by means of its aggregatebreaking force, multiplied by the spinning loss factor. This factor varies according to thevarious classes of wire ropes.
The measured breaking forceis determined in laboratory, by means of wire rope traction.
.
The forces indicated on the tables of the Cimaf technical manual always
represent the ropes minimum breaking force.

2.4 Preforming
The Cimaf wire ropes can be provided both preformingand non preforming; however,in the majority of applications, preformed is more recommended than non preformed.The difference between a preformed and a non preformed rope consists in that whenmanufacturing the former, an additional process is applied, which makes the strandsand the wires stay laid in helical shape, remaining placed inside the rope in their naturalposition, with a minimum of internal tensions.
The main advantages of the preformingrope can be numbered as follows:
1. In the non preformed rope, the wires and the strands have the tendency to straighten,and the force required to keep them in position causes internal tensions to which areadded the tensions caused in service when the rope is curved in a pulley or in a drum.
The internal tensions cause pressure between the wires in the region of contact betweenlayers and between strands which move reciprocally the moment the rope is curved,causing a sharp internal friction. In the preforming rope the internal tensions are minimum,and therefore, friction and consequently rope wear is minimal.
The preformed wire ropes, on account of having minimum internal tensions, have greaterresistance to fatigue than the non preformed ropes.
2. Handling is made much easier by the absence of internal tensions.
3. Rope balanced is ensured, each strand having equal tension equal to the other, dividingthe load into equal parts between the strands.
4. Handing is safer, the rope being free from tensions, not having the tendency to escapefrom your hand. Secondly, if a wire ruptures by wear, it will remain lying down in itsnormal position, not bending outwards, which would make it dangerous to handle.

3.1 Working loads limit and design factors
Note: The reference Minimum Breaking Force (Fmim) is also known as Minimum BreakingLoad (MBL).
Working load limit is the maximum load that the wire rope is authorized to support.
The design factor (DF) is the ratio between the minimum breaking load (MBL) of the ropeand the working load limit (WLL), i.e.:
An adequate design factor will ensure:
- Safety in load movement operation;
- Performance and durability of the wire rope and, consequently, cost effectiveness.
The table below recommends the minimum design factors (DF) for various applications:

3.2 Constructional Stretch of the wire ropes
Pre-stretched Ropes
There are two kinds of longitudinal stretches in wire rope, i.e.: constructional and elastic.
Constructional Stretches
Constructional stretches is permanent and starts just af ter a load is applied to the wirerope. It is motivated by the adjustment of the wires in the rope strands and by the settlingof the strands in relation to its core.
Constructional stretches occurs in the first days or weeks of ser vice of the wirerope, depending on the applied load. On the conventional wire ropes, its value variesapproximately from 0.50% to 0.75% of the length of the wire rope under load.
Constructional stretches can be almost totally removed through pre-stretching of the wirerope. The pre-stretching operation is done by a special process and with a load whichmust be greater than the ropes working load limit, and lower than the load corresponding
to its elastic limit.
In certain installations, such as, for instance, in Blast Furnace Skip, the elongation ofthe wire rope can not exceed a certain limit; it must be pre-stretched. It s also usual topre-stretch the rope to be used in suspension bridges or similar services.
Cimaf is capacitated to pre-stretch wire ropes with diameters up to 58 mm.
Elastic StretchesA deformao elstica diretamente proporcional carga aplicada e ao comprimento docabo de ao, e inversamente proporcional ao seu mdulo de elasticidade e rea metlica.
The metal area of a wire rope varies as a function of the construction of the wire rope. It iscomprised by the sum of the cross-section areas of the individual wires which compose it,except for filler wires.
The calculation of the metal area of a wire rope or strand can be done by means of theformula below. Although this calculation is not exact, its result is very approximate.
Where,
A = metal area in mm2;F = multiplication factor given in the following table;d = nominal diameter of the wire rope or strand in millimeters.
Notes: For ropes with 6 strands with IWRC add 15% to metal area; with WSC add 20% and for
ropes with 8 strands with IWRC add 20% to its metal area. In general, the elastic stretch of a wire rope can be estimated on 0.25% to 0.50%,
when the same is submitted to a tension corresponding to 1/5 of its breaking force,depending on its construction.
Note:
Elastic stretch is proportional to the applied load as long as it does not exceed theelastic limit value of the rope. This limit for usual wire rope is approximately 55% a 60%of its minimum breaking load.
Modulus of elasticity of wire ropes:the modulus of elasticity of a wire rope increasesduring its service life, depending on its construction and the conditions under which it isoperated, such as intensity of the applied loads, constant or variable, bends and vibrations
to which it is submitted.
The modulus of elasticity is smaller on the new or unused ropes, being that for used ornew pre-stretched ropes, the modulus of elasticity increases approximately 20%.
Next we provide the approximate modulus of elasticity of the usual constructions of newwire ropes.

3.3 Diameter of a wire rope
The nominal diameterfor the rope is the one by which it is designated.
The actualdiameter for the rope must be obtained measuring in a straight part of rope,in 2 positions with minimum spacing of 1 m. Two measurements must be taken in eachposition, with a 90offset, of the circumscribed circle diameter. The average of these 4measurements must be the actual diameter.

4.1 Choice of construction as a function of the application
The flexibility of a wire rope is inversely proportional to the diameter of its externalwires, while the resistance to abrasion is directly proportional to this diameter. As aconsequence, a composition with fine wires can be chosen when the bend fatigue stressprevails, and a composition of thicker external wires when the work conditions requiregreat resistance to abrasion.
The table below stands as a general rule.
By the table above, the 6x41 WS construction wire rope is the most flexible one, thanksto the smaller diameter of its external wires; however, it is the least resistant to abrasion,while the contrary takes place with the 6x7 construction wire rope.

D = Diameter of the sheave or drum
d = Diameter of wire rope
(ISO 4308) Sheave groove For optimum rope life, the sheave groove profile should becorrectly matched to the rope diameter. The groove radius, should lie within the range0,525d to 0,550d, with 0,537d, where d is the nominal rope diameter.
4.3 Fleet angle
According to the recommendations of the standards, the fleet angle of wire rope in thesegment between the sheave and the drum must not exceed;
a = 1 30 for conventional wire ropes (Classes: 6x7, 6x19, 6x36, 8x19, 8x36), withwinding in drums with no groove drums.

= 4 for conventional wire ropes (Classes: 6x7, 6x19, 6x36, 8x19, 8x36), withwinding in drums with grooved drums.
When a rope is coiling in multiple layers on the drum, the fleet angle at the flanges shouldbe greater than 0.5 to avoid rope pile-up.
These recommendations seek to prevent the wire rope from being damaged, for if the fleetangle is greater that the maximum indicated, we will have two inconveniences:
The wire rope will maintain sharpfriction with the sheave flangeincreasing the wear of both;
During o winding, the wirerope will maintain sharpfriction with the adjacent turnalready wound in the drumincreasing its wear andpromoting damage which willinfluence its service life, as wellas its safety.
Although a recommendation waspresented regarding the wire ropesfleet angle on the sheave segmentwith the smoothdrum (with nogrooved drums), the standardsrecommend that all the hoistingequipment must be equipped witha drum with grooved drums. Thisrecommendation is due to thefact of the inconvenience of thewire rope, when wound, it leavesvoids between the winding turnson the drum, making the upperlayer go into these voids providinga disordered winding and, as aconsequence, influencing its servicelife and safety.

5.1 How to handle
The wire rope must be handled with care so as to avoid throttling (knot), causing aharmful twist as show in the example below:
The wire rope must never be allowed to take the shape of a loop as shown in figure 1.However, a knot can be avoided if the loop is promptly undone (opened).
As shown infigure 2, with the loop closed, thedamage is done and the load capacity of the wirerope compromised, and the same being out of theconditions for use.
Figure 3shows the result of the knot, for, even ifthe individual wires have not been damaged, the
wire rope loses its proper shape. With the wiresand the strands out of position, the wire rope issubject to uneven tension, exposing it to rupture byoverload, in addition to causing excessive wear tothe displaced strands.
Caution: even if a knot is apparently straightened,the wire rope can never provide maximum
performance, according to the assured capacity.The use of a wire rope with this defect is

It can also be unwound by means of a rotary table, as shown in figure 5. It is importantthat when unwinding, the reel always turns around its axis and never the wire rope turnsaround the reel axis, as shown in figure 6.
5.2 Winding in smooth drum or reel
It is important that the wire rope, to be well wound, is attached correctly during itsinstallation.
If this does not happen, the first winding layer can present faults, causing, consequently,when the top layers are wound, kneading and warping in the wire rope, which will notablyreduce its service life.
The figures below present a practical rule for the correct attachment of the practical rulefor the correct attachment of the wire rope on smooth drums or reels.

The confection of a splice requires careful and skilful work. The perfect settling andpositioning of the strands in the splice segment is important.
It is recommended that a splice length is between 1,000 to 1,500 times the diameter ofthe wire rope.
The essential basis of the splicing process is show in the following example:
The example refers to splicing two wire ropes with a diameter 20 mm, with 6 strands,fibre cores and preformed. A splice length of 20 mm x 1,200, i.e., 24 m was adopted inthis example.
Phase 1: Both wire ropes will be well tied a distance about 12 m from their ends(2x12 m = 24 m of length required for the splice).

Phase 3: The ends of the wire ropes will be pushed one against the other for the strand Ato stay beside strand a, strand B beside strand b, and so on.
Phase 4: The ties will be released. Strand a will be twisted outwards of the assemblyin a length of 10 meters, and strand A shall be twisted into the respective empty space.Strands B and b shall proceed in the same manner.
Phase 5: Strands c and D shall twisted outwards from the ends of the respective wireropes, in a length of 6 meters, and strands e and F a length of 2 meters, counting from
the point of joining the wire rope, and the respective strands will be twisted into the spacespreviously emptied.
Phase 6: The figure above shows the par t corresponding to the splice when ready.
Care is required with the splices. A badly done splice represents a great hazard.

Inspection in wire ropes is of the utmost importance for an adequate and safe service life.
The first inspection to be done in a wire rope is the Receival Inspection, which mustassure that the material is as requested and has a certificate of quality issued by themanufacturer.
In addition to the Receival Inspection, two other inspections must be carried out, theVisual Inspection and the Periodic Inspection.
The Visual Inspectionmust be performed on a daily basis on the wire ropes used in loadmovement equipment and before each use for the loops. The purpose of this inspection isa visual analysis to detect damages on the wire rope which can cause hazards during theuse. Any suspicion regarding the material safety conditions must be informed and the wirerope inspected by a qualified person.
The frequency of the Periodic Inspection must be defined by factors such as: type ofequipment, environmental conditions, operating conditions, results of previous inspectionsand time of service of the wire ropes. For the wire ropes slings, this inspection mustbe done at intervals not in excess of six months, having to be more frequent when itapproaches the end of its service life. It is important that the results of the inspections arerecorded.
Whenever an incident occurs which may have caused damages to the rope or when it has
been out of service for a long time it must be inspected before the beginning of the job

When this deformation is sharp, they can change the original geometry of the wire ropecausing imbalance of stresses between the strands and, consequently, its rupture.
The most common deformation are:
a) Waviness
Occurs when the longitudinal axis of the wire rope takes on the shape of a helix. Insituations where this anomaly is sharp, it can transmit a vibration on the wire rope which,during work, will cause premature wear, as well as broken wires.
b) Crush
Crush on the wire rope is normally caused by the disorderly winding on the drum. Insituations where the disorderly winding can not be avoided, the use of wire rope with steelcore must be chosen.
c) Birdcaging
This warping is typical in wire rope with steel core in situations where a sudden release of
tension takes place. This irregularity is critical and prevents the wire rope from continuingto be used.
d) Core protusion
It is a characteristic also caused by the sudden release of tension of the wire rope, causingan imbalance of tension between the strands, preventing it from continuing to be used.
7.3 Corrosion
Corrosion decreases the load capacity by reducing the metal area of wire rope, in additionto accelerating fatigue.
It can be detected visually, when it shows up on the external part of the wire rope.
Detection of internal corrosion is more difficult; however, a few indications can point outits existence:
Variation in rope diameter: the decrease of diameter usually takes place in thefolding points of the wire rope. I n wire ropes or strands for static use, the increase of
diameter is common due to the increase of oxidation. Approximation between strands: frequently combined with broken wires in the
valleys
7.4 Unbalance of the wire ropes
In conventional wire ropes, normally with 6 or 8 strands with fibre core, a typical damagecan happen which is a ripple of the wire rope cased by the sinking of 1 or 2 of its strandsand it can be caused by a few motives:
a) Poor attachment, which allows a few strands to slide, the remaining ones beingovertensioned.
b) Fibre core of reduced diameter.c) Fibre core which deteriorate, giving no support to the strands of rope.
On ropes with several layers of strands, as in the resistant to rotation ropes and ropeswith steel core, the danger of birdcaging and raised core exists, defects which can becaused by the following motives:
d) Poor handling and/or installation of rope, giving rise to torsions or distortions ofthe same.
In case a the danger exists of the overtensioned strands breaking; in cases b and c,there is no imminent danger, however, there will be an uneven wear in the wire rope and,therefore, low efficiency.
Case d is more common for Non-Rotating ropes and with Steel Core, where the dangerof birdcaging and raised core exists. These de fects are grave and require promptreplacement of the wire rope.
7.5 Deformation*
Deformation in the wire ropes occurs mainly due to misuse or irregularities in theequipment or, further, by inadequate methods of handling and attaching.

e) Kink or knot (dog leg)
It is characterized by a discontinuity in the longitudinal direction of the wire rope which inextreme cases reduces its load capacity. It is normally caused by improper handling or
installation.
7.6 Replacement criteria
Even if the wire rope works in optimum conditions, a moment comes in which, afterreaching the end of its service life, it needs to be replaced by virtue of its natural
degeneration.In any installation, the problem consists in determining what is the maximum efficiencywhich can be obtained from a wire rope before replacing it, to keep it working in completesafety, since, in the greater por tion of the installations, the breaking of a wire rope putshuman lives at risk.
There isnt a precise rule to determine the exact moment for replacing a wire rope. The
decision of a wire rope remaining in service will depend on the evaluation of a qualifiedh t it diti i t i ti b d di l

The rotation resistant wire ropes are usually manufactured with 12external strands of 7 wires each with regular right lay, laid arounda nucleus composed of 6 strands of 7 wires each with Lang leftlay which in turn are laid around a core which can be made of fibreor steel.
The term Rotation Resistant, is due to the smaller tendency ofturning of this wire rope which is grounded in the inversion of laybetween the layers of external and internal strands, annulling the
torsion moment under tension.
The ropes of this class twist a little in the beginning of applying theload, until it stays in balance.
The rotation resistant wire ropes must be used with great care andwith design factors higher than the other classes.
Special care recommended in the use of Rotation Resistantropes:
1) The general instructions for handling wire ropes must befollowed, preventing them, both when unwinding from the reeland in installing in the machine, from suffering distortions orknots which may render them useless.
2) This wire rope is very sensitive to brusque variations of loadand requires a very smooth handling. In general, there must bea weight next to the hook to keep it under tension. Most times,
the brusque variations promote birdcaging, rendering the wirerope useless.
3) It must be avoided that the rotation resistant rope undergoesrotation during service.
4) On attaching (anchoring), it is essential that all the strands of therotation resistant rope are well attached, including the internalones. To achieve that, attachment by means of clips or otherpressure-actuated fittings must be avoided, the use of socketsis recommended.
5) This rope must be wound on a drum with channel and sufficientdimensions to prevent overlapping of different layers.
6) The rotation resistant rope is usually recommended forequipment which works with only a single wire rope line, orfurther, when the equipment works with two very close ropelines, its hoisting height being very high.
Note:By virtue of the special cares which are required in
installation, handling and operation of the rotation resistant ropes
(18x and 19x7), it is recommended to limit is employment only to
the essential cases.
