Steel Wire Rope
Wire Rope is made up of steel wires, generally braided in a helix(spiral) forming units known as strands. The strands in the wirerope can vary in accordance with specic and desired properties.
Wires
Wires are produced by reducing the diameter of the base wire, af -ter passing through a series of dies and formers while have an axialforce applied to it.
The wire´s properties depend on its chemical composition, micro-structures, grain size, segregations and process conditions.
Wires comply with the required ASTM A 1007, JIS G 3525, API 9 A,RRW 410 F, ISO 2232 and other internationally recognized stan-dards.
Strands
Strands are formed by wires of the same or dierent diameters,twisted over a central core.
Core
The core or nucleus is the central axis of the wire rope, aroundwhich strands are wrapped. We use various cores, including steel,natural ber or synthetic.
Wire Rope
Group of strands twisted helically around a core or nucleus.

Lay length
The lay of a steel wire rope is determined by the form in whichthe strands are rolled in the wire rope and the way the wires arerolled in the strands.
The length of lay of a steel wire rope is the linearly measured distance,from one point of the strand to another point on the same strand, af -ter completing a pass around the core of the wire rope (360°).
According to the direction of the strands over the core, they canbe to the right or the left.
According to the direction of the wires in the strands and the rollingof these over the core, the wire rope can be of two types: regular layor lang lay. These can also be rolled to the left or right.
Regular Lay: The position of the wires in the strands is opposite tothe direction of the wire rope, see following gures. This type of
conguration allows the wire rope to be compact, well balancedand with excellent stability.
Lang Lay: The position of the wires in the strands provides it with thesame direction of all the strands within the wire rope. This providesexcellent fatigue resistance as well as resistance to abrasion damage.

The wire ropes should not be stored in places that emit corrosvapors and should not be in contact with the oor.
Maintenance should be comprised of inspections, lubrication acleaning with regular frequency. Defects or irregularities should noted and rectied. The inspection should always include the staing point of the wire rope as well as its installed.
The inspection should always include the settling up of the termnals, with emphasis on the point of entry.
An adequate lubrication prolongs the useful life of a wire rope becauit reduces corrosion and abrasion caused by the friction of twire rope against the pulleys.
The frequency of lubrication depends on the following factors
• Retained lubrication from the manufacturing process• Elevator use• Security factor and working temperature
To install the wire rope in a winch or drum, it’s advisable to follow thefollowing instructions:
Before installing a new wire rope, the pulleys and drums shouldbe checked to insure they have no degradation or defects. Whena degradation or defect is found in the pulley and/or drums, this
should be replaced with new ones, matching the prole and di-ameter of the new wire rope.
Rotating or rotating the free end of the wire rope can cause thede-braiding of the wire rope.
The terminals and/or accessories cannot be removed or installedwithout making sure that the twist is maintained.
This transportation operation should be performed in such a wayas to completely avoid any possible of contact of between thewire rope and loading equipment.

Steel Wire Ropes Classifcation
Steel Wire Ropes are classied by diameter, number of strands,type of core and construction.
The types of strands in wire ropes are:
1. SIMPLE CAP COMMON STRAND
The most common example of simple lay strand. Construction is com-
prised of seven wires. It has a central wire and six wires of the same diam -
eter that revolves around it. The most common composition is 1+6=7.
2. SEALE STRAND
Construction in which the last layer contains the larger diameter
wires than the interior strand, giving the strand more resistance to
abrasion. The most common composition is 1+9+9=19.
3. FILLER STRAND
This strand is distinguished by having ne threads that ll the existing
spaces between two wire layers. This type of strand is used when a largemetallic section wire rope is required with a good resistance. The most
common composition is 1+6/6+12=25.
4. WARRINGTON STR AND
This strand is characterized by having an exterior cap formed by wire
of two dierent diameters, alternating their position in the crown
The type of strand most commonly used is 1+6+6/6=19
5. WARRINGTON SEALE STRAND
This is a combination of the previous two strands and combines thei
best qualities: The conjunction of ne interior wires allows for exibility
while the exterior cap of wider diameter wires, gives resistance to abra
sion. The most common construction is 1+7+7/7+14=36
6x26 steel cable combines resistance to exing and abrasion, givin
good wire live during usage 1+5+(5+5)+10=26
Most Common Wire Rope Constructions
The physical and mechanical properties of the dierent constructiothat EMCOCABLES® manufactures are detailed in the followitables. These are taken using the ASTM1023 standard.

Below is the recommended factors comparing the assumed breakiload as compared to the established working load.
Security Factor
Selection of Non-Rotating Wire Ropes
There is no precise rule for determining when to utilize non-rtating wire ropes in the rst instance, it is important to considthe experience obtained with previously wire rope.
The variables that help determine this are:
• Lift height.• Wire Rope diameter.• Pulley diameter.• Number of Lines.• Pulley disposition.• Specic torque of the wire rope.
It is not recommended to use non-rotating wire rope when tload is guided. (rotational resistance)
Specic Precautions and Installation:
Due to its particular design, non-rotating wire rope presendierences in comparison to 6 lace wire rope. The form in whithey behave, degrade and break, diers in respect to all othconventional constructions.

The most common use of these wire ropes is in cranes in order tolift guided loads.
Recommendations for Installation and Use
Non-rotating wire ropes are very delicate and thus require specialcare during mounting, use and in the selection of maintenanceequipment. The following is a list of conditions and precautions thatshould be observed in order to use thenon-rotating wire rope:
• The diameters of the drum and pulleys used for 18x7 or 19x7
wire ropes should not be less that 40 times the diameter of thewire rope. A diameter equal to 54 times the diameter of the wirerope or greater is recommended.
• The 18x9 non-rotating wire rope should be used with pulleysand drums whose diameter should not be less that 25 times the
diameter of the wire rope. A diameter 36 or more times greateris recommended.
• Non-rotating wire ropes should always be under to tension,thus it is necessary to install a hook or counterweight in order tomaintain the wire rope taught even when there is no load.
• Rotating or spinning the load should be avoided because thattorsion, distortion will condition will reduce the useful life of thewire rope.
• The entry angle of the wire rope into a pulley should not begreater than 1.5°´.
• If the non-rotating wire ropes are to be mounted on a hoistingequipment, it is prudent to limit the legs to only two, due to thefact more legs cannot be used.
• It is recommended that the ties on the end of the non-rotatingwire rope be made of cast Zinc or any other metal for low fric -tion. The use of staples, in this case, is not a good practice be -
cause they allow slipping of the exterior laces (strands) over thecore, causing potential surface defects and internal deviations.
Wire Ropes for the Petroleum Industry
These recommendations apply to all wire ropes in general use
1. Use of Sling or Chains
When it is necessary to move the wire rope reel with slings chains, wood blocks should be used between the wire rope athe element used (to lift the roll) in order to prevent damage the wires or distortion to the strands in the wire rope.
2. Use of Bars
When bars are used to move the roll, these should be leveragagainst the edge of the roll, not the wire rope itself
3. Sharp objects
The Roll should not roll or fall or hard or sharp objects in suchway that can cause damage to the wire rope.
4. Falling
The roll should not be allowed to fall from the truck or platformthis can damage the wire rope or break the roll.
5. Mud, Dirt, Ashes
The roll should not come into contact with anything that ccause surface damage, rust or scratches as dirt, mud or ash.
Placing the roll on a pallet, will help to transport as well as prtecting the wire rope against damage

7. Excess of wire rope or dead caps
The number of dead caps or excess wire rope should be maintainin accordance with the equipment manufacturer’s standards.
8. New Wire Rope
When possible, the new wire rope should be carefully controlland monitored, under loads and speeds, for a short period aftinstallation. This allows the wire rope to settle into the work evironment.
The EMCOCABLES® manufactured SUPER B SHRIMP and SPER B FISH galvanized steel wire ropes for shing have beedesigned according to the heavy work loads shing ships carout, as well as the great power developed by these ships todaOur high quality thoroughly meets the demands of the modesherman’s most important work tool, high resistance, long lwire ropes.
The production of our shing wire ropes is meticulously montored during the drawing, galvanization, stranding and closiprocesses. The most rigid international standards are set for tproduction of our shing wire ropes. Our quality control is n
just limited to approving nal wires ropes, but to strict oversigduring each of the manufacturing processes. It is to this attetito detail that we produce shing cables of unbeatable quality.of the wires in our shing wire ropes are strong, resistant to tesion and heavily galvanized.
Together, these factors make our wire ropes resistant to corrsion, abrasion, deformation and yet still maintain a great exibity, an important requirement in this type of wire ropes.
The individual diameter of the wires and the geometric designthe strands have been technically and carefully calculated, thgiving the SUPER B shing wire ropes magnicent physical proerties.
The polypropylene center is specically designed for our shiwire ropes. It is dense, uniform and resistant to seawater. It hthe best characteristics of natural ber core strands but none the disadvantages.
HANDLING DURINGINSTALLATION
2
1. Thread Block
The blocks should be threaded without wearing against theslot in the pulley
2. Line changes and cutIts good practice during a line change to suspend the ying blockfrom the crown, in a single line. This tends to limit the amount ofrubbing over the guards or spacers, to diminish the formation ofbends. This practice is also very eective in the cutting procedure.
3. Tension
Tension should be maintained from the moment the wire rope isremoved from the roll in order to restrict its movement.
There should be enough tension in the wire rope in order to assurea good pay o and accommodation.
4. Threading with a rotating type clamp
It is recommended when a worn wire rope is going to be replacedby a new one, the use of a clamp to attach the new wire rope tothe old one is done.
It should not be welded onto the used wire rope in order to pull itthrough the system.
5. Twisting
There should be the utmost attention paid in order to avoid thetwisting of the wire rope, because the formation of a bend, cancause the entire wire rope, or a section.
6. Cleaning
The use of solvents can cause damage to the wire rope.
If the wire rope gets covered in dirt, sand or any other contami-nating material, it should be cleaned with a brush.

PROBLEMS THAT CAN ARISE WITH PULLEYS AND THEIR SOLUTI ONS
Pulley Wire Rope Incidents, Causes Observations
Too Small Groove Normal
The wire rope fatigues rapidly becouse of brunt folds, which caused the outer
strands to deteriorate quickly. The strands of the wire rope attack the pulley
and draw a spiral print.
Replace the pulley.
A convenient pulley should have a relation
of 120 to 140° and the borders should
have an inclination of 40 to 50°Overly Wide Normal
The wire rope wears out due to the slidings and the inertia of the pulley, of a
false groove, and fatigues prematurely due to abrasion.
Groove Evidence by a
Mark EvidenceNormal
If the previous wire rope had left an impression on the bottom of the groove,
this can have a ling eect on the exterior wires of the wire rope.
Groove Evidence by a
Worn Side
Due to continuous excessive rubbing at a great deection angle or a
defective pulley – drum alignment.
Rectify the pulley or replace it well. Test
alignment
Deform Groove
A at spot on a point on the pulley creates a bump in the wire rope each
pulley revolution. The cumulative eects of this cause a constant fatigue on
the exterior strands and engenders a vibration.
Replace or rectify
Used Pulley New The wire rope eliminates old impressions and wears quickly.
Bearing or Axis of
Broken PulleyNormal
Provokes an oscillation and the cable whips around thus reducing its useful
life. The wearing of the axis tends to cause a false rotation in the pulley and
the wire rope fatigue, generally around the connection.
Replace the bearing or remount the axis
Poorly Rounded or
Coated PulleysNormal
The wire rope also whips around and the damaged face can remove itself
from use or at least rub together against the live edge, causing rapid wear.
Sti Pulley Normal The wire rope is worn by ling and produces grooves in the pulley.Re-grease the axes of the pulleys and mak
sure they spin freely
Notched Pulley Normal A Notch can destroy thewire rope. Change Wire Rope
Undulated Pulley
Overly Heavy PulleysHas a moment of inertia such that its movement doesn’t adjust to the wire
rope, and acts as a grinder against the exterior wires.Change Wire Rope
Normal Pulley Used
The diameter of the groove section results small, if a new wire rope is
mounted, it will be too loose in the pulley and brush the sides of the pulley,
deforming it and eventually destroying.
Too SmallThe wire rope, when isn´t tensioned, generally tends to atten, then it
deforms and eventually destroys.
